Cork underlayment + polyethylene sheeting = most cost effective insulator on the market.

Subject: Cork flooring in a basement (with subfloor panels)

Message Body: Hello, I’m currently renovating my basement (approx 1400 sq. ft.), and am looking into different flooring options, one of which is cork flooring. I read the FAQ on your website regarding basements and using a vapor/moisture barrier on the floor, but I wanted to know if it is a suitable option to use an engineered subfloor panel (Home Depot link: They are particle board with plastic moisture barrier underneath. I would likely still use a clear plastic moisture barrier on the concrete floor, followed by the subfloor panels, followed by cork underlay and finally the cork tiles or floating system.

Could you please let me know if this seems logical or if there are some other concerns or potential hazards? I like the look, feel and insulation value that the cork floor provides but am concerned about the possibility of moisture affecting the performance of the cork.

Thank you, Braden Deane

Dear Customer,

We’ve received your flooring sample order and will ship that tonight with Canada Post. In your situation, I would “skip” the subfloor system. The cork underlay + polyethylene sheeting = most cost effective insulator on the market. The Dricore product you show is a “nice” product for a high price ($1.75/sf). Cost of installation for the panels will have to be calculated as well (some guys charge as much as $1.50/sf to put these down). Your square footage indicates you would need 350+ panels ($2446.50 for exactly 350 panels). Typically you will need 10% – 15% waste for the DriCore (ad another 35 – 40 panels to that number). And as you’ve discovered, you still need the polyethylene sheeting for the DriCore. The polysheeting is the moisture barrier. It is “industry standard” and will do everything you need it to do. In fact, that is the only moisture requirement we have in a basement.

I propose the 6mm cork underlay ($0.95/sf) + poly sheeting ($0.06/sf) and red duct tape ($9.99/roll) = a beautifully insulated basement for $0.90/sf. Add the cork floating floor and you are done. If you insist on having a HEAVY DUTY insulator, our 12mm cork underlay ($1.79/sf) is cheaper and faster to install than the DriCore and would provide double or even triple the insulation the Dricore would offer.

Personally I’ve seen 6mm cork underlay + cork floating flooring offer a 7 Celsius increase in temperature in a cold basement. The 12mm cork underlay + 11mm floating floor will raise the temperature in the basement by 12 – 15 deg. Celsius.

A glue down tile is not allowed in a basement. The warranty is void. Even if you use Dricore (and do everything right), you still can’t glue the cork tiles into place. The OSB surface on the DriCore will not allow the glue to “stick”. You would be forced to add MORE sheathing (subfloor grade 3/8” plywood) to the DriCore ($1.50/sf + screws + cost of install/time). And we still wouldn’t offer a warranty due to “improper installation”.

Your situation is unique to all others that have come before you. Ask yourself if “7 celsius” increase in temperature in your basement is “good enough” for you. If it is, then the 6mm cork underlay will be just fine. If you desperately need added warmth (because you can’t get the temp above 12 C without rerouting the entire heating system) then the 12mm cork underlay would be the next step. You can do away with the DriCore subfloor system. You don’t need it if you are using cork + cork. But then again, I’m biased J

Please let me know if there is anything else I can help with.
Best regard

How to install a unheated space with cork flooring?

(10:35:23) Visitor 74789261: Hi, I’m leading the build of a yoga/shiatsu studio and my client would like to install a cork flooring. The building has a concrete slab and will NOT be heated permanently, as it’s off-grid in the wood in a vacation centre. Which of your product would best fit this application?
(10:35:45) *** Cacork Floor joined the chat ***
(10:35:54) Cacork Floor :Cork Glue down tiles with 3M 30NF Green Fastbond Contact Adhesive  
(10:36:24) Cacork Floor : As soon as it is “unheated” or goes without HVAC, the warranty is void – but then again so would ANY floor.
(10:36:53) Cacork Floor : In the Pacific coast region this is not much of an issue.
(10:37:10) Customer: I’m from Quebec
(10:37:11) Cacork Floor : IN more extreme areas the life of any floor will be reduced when exposed to extremes.
(10:37:57) Customer: The floor will go through temperatures from -25 to +25.
(10:38:13) Cacork Floor : Yep…reduced life expectancy = to be expected.
(10:39:34) Customer: What would be the best way to prevent damage, I’m thinking especially in terms of underglooring. I was thinking vapour barier plus foamy underlayment
(10:39:36) Cacork Floor : My shift is over – is there anything else?
(10:39:49) Cacork Floor : Please send your questions in an email
(10:39:57) Cacork Floor : Contact us
(10:40:29) Cacork Floor : The details of such an install are pretty tough to get done over a chat. It should take me 1-2 hours of typing to get it all down.
(10:40:43) Cacork Floor : Please send email with your question and I will try my best to answer tomorrow.
(10:40:55) Customer: Ok, thanks!


I happen to build a Yoga studio that’s going to be off-grid in the forest, here in Quebec. My client insists on using cork for flooring as it’s a natural, soft and “warm” material. I’m concerned because the building will be left unheated for long periods of time, so the humidity rate will fluctuate a lot. This would probably cause expansion and contraction to the floor, especially if it’s a floating floor, and could badly damage it if it happens too often or too quickly. A fireplace will be added to the room and I’m afraid that someone coming in the dead of the winter might make a fire too hot too quickly and the humidity rate would change rapidly.

The building is round, 27 feet of diameter inside. Right now the floor is a concrete slab. What would be your best product to tackle those challenges? I understand very well the fact that because humidity and heat will not be constent, your warranty will be void. I want the best option to mitigate my client needs with the conditions the building is into.

I was also considering installing a polystyrene insulation between the concrete and the cork floating floor for added insulation and protection from temperature differences between the top and the bottom of the board.

Please indicate me what solution you would recommend to me given the circumstances, and which of your product s best suited.

Cancour Floor Answer
Thank you for your email.

The best flooring for unheated space is cork glue-down tiles, but you must use 3M 30NF Green Fastbond Contact Adhesive to install the cork tiles. Ray cork installed cork tiles in a trailer in Winnipeg area 15 years ago. The cork floor still in very good condition.  You can call Ray about installation cork tiles. He provides cork glue down tiles installation service. (Ray 204-770-0200)

This is one of the toughest things you will do – install “indoor” materials in an unheated space in Quebec.  Everything you install will have a limited lifespan.  

A cork floating floor + 6mm cork underlay = a nice way to insulate the space.  This will do what the ‘polystyrene’ insulation would do without the big expense.  A cork floating floor in your situation may only have 7-15 years of life in it.  A carpet = 7-15 years of life.  Vinyl = 3-7 years.  Laminate = 3-10 years.  Linoleum = 5-15 years.  Hardwood = 5-15 years.  As you can see, everything we have that is “interior” grade is going to have a vastly shorter life span.  

Cork Glue down tiles is the best flooring for you. The down side of glue down tiles is installation requires more time. you may need a professional installer like Ray cork to install cork glue-down tile. Installation fee is more expensive than floating floor. …..

How to remove glue on the top of cork floor?


(05:01:59) Visitor 96145565: Can anyone give me advice on how to remove glue from my cork floor.
(05:02:14) Cacork Floor : What type of glue….on which side of the cork?
(05:02:21) Visitor 96145565: Im restoring a building and someone laid carpet tiles and glue on top
(05:02:24) Visitor 96145565: the top
(05:02:37) Cacork Floor : How old do you think the glue is?
(05:02:48) Visitor 96145565: a couple decades im sure
(05:03:00) Cacork Floor : What have you attempted thus far
(05:03:29) Visitor 96145565: nothing so far, not sure where to start. The glue is pretty much seeped in
(05:03:44) Cacork Floor : “Seeped in” would be very rare for cork.
(05:03:53) Cacork Floor : It would imply the cork was completely bare of finish
(05:04:27) Visitor 96145565: oh really?
(05:04:30) Cacork Floor : The first trick is always plenty of water – as hot as you can handle it and then scrape it off the finish.
(05:04:42) Cacork Floor : A finished cork floor = same as a finished hardwood = same stuff used.
(05:04:47) Visitor 96145565: okay sounds good we will try that
(05:05:01) Visitor 96145565: do you know of any companies that restores cork?
(05:05:12) Cacork Floor : Once 90%-99% of the glue is gone…you can then have the cork sanded and refinished.
(05:05:20) Cacork Floor : I do….in Winnipeg Manitoba Canada
(05:05:27) Visitor 96145565: michigan?
(05:05:28) Visitor 96145565: lol
(05:05:47) Cacork Floor : Sorry – no.
(05:06:01) Visitor 96145565: oaky thank you for your help
(05:06:15) Cacork Floor : How thick is the cork?
(05:07:03) Visitor 96145565: not sure. I think it was laid when the building was build 1927
(05:09:36) Cacork Floor : The first thing you want to know is the THICKNESS.
(05:10:04) Cacork Floor : If the cork is too thin…you won’t be able to sand/refinish = no use trying to remove the glue because the fight to get the floor in shape won’t work.
(05:14:34) Visitor 96145565: how thick does it need to be to refinish?
(05:14:49) Visitor 96145565: or to be worth refinishing?
(05:14:56) Cacork Floor : 4mm or thicker…a 3.2mm “1/8” is too thin
(05:15:15) Cacork Floor : You’ll need to get out your metric tape measure and see how thick it is.
(05:16:45) Cacork Floor : If the floor is original to the house…and for 1920’s it is VERY possible it is…it is worth a HUGE amount of money as a restored “original cork”.
(05:18:46) Cacork Floor : Is there anything else I can help with?
(05:21:05) Cacork Floor : Good bye

What is the 6mm cork underlayment acoustic value on a concrete slab?

(06:56:27) Visitor 74074667: Hello, I am considering using a 6mm cork underlayment for a glued engineer hardwood application on a concrete slab. The adhesive I am considering to adhere the cork underlay to the concrete slab is Bostik Vapor-Lock which has acoustic characteristics and using the same adhesive to attach the engineered hardwood to the cork underlay. The system would then provide acoustic value to everything except for the hardwood itself. Would this make for a good floor?
(06:56:40) *** Cancork Floor joined the chat ***
(06:56:54) Cancork Floor : Is the slab at, above or below grade?
(06:57:29) Visitor 74074667: The slab is above grade, 8 th floor of a condo highrise.
(06:58:14) Cancork Floor : Then a vapour barrier adhesive isn’t really needed. So long as the adhesive is rated for “concrete” and “cork underlay” you should be fine.
(06:58:42) Cancork Floor : The “double stick” is one of the highest rated (most expensive) installs we have in the flooring industry.
(07:01:01) Visitor 74074667: I was trying to enhance the acoustic rating by using an acoustic adhesive. The condo association wants a floating floor and I am trying to get them to approve a glue down system with better than normal acoustics. 
(07:01:52) Cancork Floor : Without knowing the ‘acoustic rating’ of the adhesive, it is super difficult to figure out how the adhesive will effect the rating for a cork underlay.
(07:02:18) Cancork Floor : In theory the double stick is the best option (from a structural) stand point.
(07:02:54) Cancork Floor : I’m not sure what the Bostik will do to increase the ratings. The 6mm cork underlay is accepted by 90% of condo boards = already approved.
(07:05:09) Visitor 74074667: It appears the adhesive has a IIC rating of 50 for a 6 inch concrete slab, our slab is 8 inches. Would the adhesive affect/reduce the rating for the cork underlay or just add to it?
(07:06:09) Visitor 74074667: The approval you mention, is it floating or glued application?
(07:06:34) Cancork Floor : STC ratings are odd things.
(07:06:51) Cancork Floor : The 6″ concrete = 28- 33 dB all by itself.
(07:07:22) Cancork Floor : So 8″ concrete = 36-38″ dB
(07:09:16) Cancork Floor : The adhesive in theory should add to the ratings of the cork…but the adhesive manufacturer must list cork and concrete as two of the substrates
(07:09:45) Visitor 74074667: Yes they do, both.
(07:10:08) Cancork Floor : Then the only thing you need are the right trowels for both formats of adhesive.
(07:10:48) Cancork Floor : A cork underlay of 6mm would be regardless of installation application. The reason: 6mm of cork is 6mm of cork. That doesn’t change.
(07:11:01) Cancork Floor : Have you received approval for 6mm cork underlay under your hardwood???
(07:12:11) Visitor 74074667: Not as yet, our condo does not have specific criiteria, all they indicate is an acoustic padding.
(07:12:25) Cancork Floor : Then the 6mm will pass.
(07:12:40) Cancork Floor : It is rated as acoustic underlayment
(07:13:05) Visitor 74074667: Can you provide me with the IIC acoustic rating for 6mm cork?
(07:13:20) Cancork Floor : I have Delta IIC ratings for cork + cork underlayment
(07:14:52) Visitor 74074667: What is Delta, I have not come across that term in my research?
(07:15:09) Cancork Floor : How much time do you have today???
(07:16:36) Visitor 74074667: Some, is it that complicated? A competiting underlay Dura-Son MB indicates a FIIC rating of 69
(07:16:54) Cancork Floor : Yes…it should take me 3-4 hours of time to type it out.
(07:17:10) Cancork Floor : FIIC = FIELD IIC testing = almost useless.
(07:17:22) Cancork Floor : Go ahead and Google “Delta IIC ratings”
(07:18:19) Visitor 74074667: It is interesting because some in the industry suggest that is a better indicator than the lab IIC.
(07:18:56) Cancork Floor : Nope…Delta IIC is a PURE number that is ONLY for floor+ underlay
(07:19:19) Cancork Floor : STC/IIC and FIIC ratings REQUIRE the EXACT floor/ceiling assembly as tested = never happens.
(07:19:39) Cancork Floor : If you require more help…please send an email: via contact us
(07:19:52) Visitor 74074667: I am trying to provide a communication to the Condo Board that they may understand and accept.

What is the density of Forna cork tiles?

(10:09:14) Visitor 41003281: I can’t seem to find the % of density of your cork tiles, can you help?
(10:09:29) *** Stephanie McCarthy joined the chat ***
(10:09:38) Stephanie McCarthy : Cork glue down tile density?
(10:09:55) Stephanie McCarthy : roughly 550kg/cubic meter
(10:10:16) Visitor 41003281: Is that for all types?
(10:10:21) Stephanie McCarthy : pretty much
(10:10:34) Visitor 41003281: Thank you
(10:10:35) Stephanie McCarthy : That is the level needed to create a floor tile.
(10:10:41) Stephanie McCarthy : The cork underlay is different
(10:11:14) Visitor 41003281: What i am surching for are tiles to glue
(10:11:40) Stephanie McCarthy : no problem…the 3 wall tiles have a slightly lower density but still higher than the underlay
(10:11:59) Stephanie McCarthy : This is for a floor application?
(10:12:07) Visitor 41003281: Yes
(10:12:44) Stephanie McCarthy : All of them are same level of quality
(10:12:51) Stephanie McCarthy : Just different thicknesses.
(10:13:34) Visitor 41003281: Thank you for your help and excuse my english, I’m french.
(10:13:46) Stephanie McCarthy : No problem. Have fun.

Is cork flooring suitable for a hot yoga room?

(10:54:36) Visitor 84611895: hello, is cork flooring suitable for a hot yoga room?
(10:55:05) Cancork Floor : Sometimes…it depends on the setting, the material and the installer.
(10:55:10) Cancork Floor : And how “hot” is hot?
(10:55:30) Visitor 84611895: 100f
(10:55:37) Visitor 84611895: 50 % humidity
(10:55:42) Cancork Floor : Cork itself doesn’t care…but the ADHESIVES and the FIBRE BOARD care a WHOLE BUNCH!!!!!
(10:56:18) Cancork Floor : A floating cork floor in a traditional yoga studio (no heat, no humidity) will receive 2 coat of polyurethane at time of install (to be done by the installer) and that makes the floating floor water resistant. It won’t care (too much) about ‘mopping’. Of course “mopping” will be limited to slightly damp mop with the appropriate cleaners applied (can be dealt with at the level of the owner of the flooring = proper cleaning procedures found on our website).
(10:56:29) Cancork Floor : We will recommend installing the glue-down cork tiles in a hot yoga studio, but not the floating flooring. Many yoga studio owners have turned to the glue down cork tile format (with glue and polyurethane needed for the job). We have recently had an 8mm cork glue down tile installed in a Moksha yoga studio in Squamish BC.
(10:57:03) Cancork Floor : The 100F = 37 – 38 C.
(10:57:09) Visitor 84611895: yes
(10:57:33) Cancork Floor : This is well outside the ‘happy’ range for most adhesives. You would have to work with the super expensive stuff with a glue down tile + the expensive installer.
(10:57:42) Cancork Floor : How big is the space?
(10:57:54) Visitor 84611895: 800 sq feet
(10:58:16) Cancork Floor : Do you own the space? Or are you renting? How long do you feel the hot yoga will be a fad?
(10:59:12) Visitor 84611895: this space will go for 10 years before we relocate to a larger studio
(10:59:32) Cancork Floor : Do you feel the “hot” yoga trend will continue for the full 10 years?
(10:59:37) Visitor 84611895: yes.
(10:59:45) Visitor 84611895: its been going strong already for 10.
(10:59:50) Cancork Floor : And you own the space?
(10:59:54) Visitor 84611895: yes
(11:00:07) Cancork Floor : OK…then you would benefit from the high-end install.
(11:00:13) Cancork Floor : What produces the heat??
(11:00:34) Visitor 84611895: inferred panels
(11:00:41) Cancork Floor : On the walls/ceiling?
(11:00:48) Visitor 84611895: ceiling
(11:00:54) Cancork Floor : What’s on the floor right now?
(11:01:07) Visitor 84611895: 10 inch concrete slab
(11:01:08) Visitor 84611895: new
(11:01:13) Cancork Floor : How new is new?
(11:01:23) Visitor 84611895: 2 months
(11:02:12) Cancork Floor : It might take another 1-2 months before you can glue to the slab….but after that, it is possible to go ahead with a solid cork tile (6mm or 8mm) glued in place using the high end adhesive.
(11:02:32) Cancork Floor : The floor is then finished with 2 coats of polyurethane = ready for use 5 days later.
(11:02:53) Cancork Floor : Is the concrete slab “at grade”, “below grade” or “above grade”?
(11:03:05) Visitor 84611895: above. mezzanine lever
(11:03:20) Cancork Floor : Excellent.
(11:04:19) Visitor 84611895: ok great. do you have anyone that can install in Alberta?
(11:04:30) Cancork Floor : – not to that level.
(11:04:48) Cancork Floor : The only person I know of who can handle that type of install = Winnipeg cork installer.
(11:05:03) Cancork Floor : He’ll use the correct adhesive….he’s done several.
(11:05:11) Visitor 84611895: how about quick tanning on it? I am journey man stone mason.
(11:05:25) Cancork Floor : ?Quick tanning?
(11:06:02) Visitor 84611895: iv been doing natural stone and tie for 25 years. I need to be shown once. then I can do it.
(11:06:35) Cancork Floor : He could not handle this install – even though he was taught by German Meisters
(11:07:06) Cancork Floor : This is a contact cement application using a high-end water based roll on adhesive with ALL the “cement” testing required for a “new” slab = ouch.
(11:07:16) *** Visitor 84611895 has rated the chat Good ***
(11:08:25) Cancork Floor : The adhesive I’m thinking of = 3M 30NF Green Fastbond adhesive
(11:08:35) Cancork Floor : It is roughly $180 per gallon
(11:08:42) Cancork Floor : lays roughly 170sf per gallon
(11:09:19) Cancork Floor : It has a better “temperature” range than the adhesive I sell. And at 2.5 TIMES more expensive, there are few who will work with it…because of the cost.
(11:09:44) Cancork Floor : Please visit the Canadian website:
(11:11:07) Cancork Floor : The thicker the cork, the LESS LIKELY the heat will reach the adhesive. This is the most vulnerable part of the system…too much heat and the adhesives will release = big mucky mess
(11:12:13) Visitor 84611895: this is very helpful thank you
(11:12:38) Cancork Floor : No problem. Remember to work with the Canadian website when ordering your free samples.
(11:13:12) Visitor 84611895: I wasn’t aware. I will. thanks
(11:13:18) Cancork Floor : No problem.

Do I need an additional underlayment with the floating floors?

(05:12:53) Visitor 40510907: Which of your cork floors is below grade
(05:13:13) Cancork Floor : all of the floating floors = click together options
(05:13:51) Visitor 40510907: Do I need an additional underlayment with the floating floors?
(05:13:59) Cancork Floor : Yes…and no.
(05:14:17) Cancork Floor : “Need” is a difficult word to translate in the building industry.
(05:14:36) Cancork Floor : In legal terms it denotes “requirement for warranty purposes”…which it is not
(05:14:54) Cancork Floor : “Need” from a personal perspective often means “want”
(05:15:10) Visitor 40510907: It is for the basement, that occasionally get water damage
(05:15:30) Cancork Floor : Then you will occasionally need to replace damaged planks.
(05:15:43) Cancork Floor : Cork underlay is not water proof.
(05:15:54) Cancork Floor : A vapour barrier is always required in basements
(05:16:07) Visitor 40510907: Ok, I was just goingto ask that
(05:16:14) Cancork Floor : A vapour barrier stops water from moving up through the slab and exiting into the air.
(05:16:22) Cancork Floor : STANDING WATER is a different animal.
(05:16:52) Visitor 40510907: How do I figure out what thickness I can use?
(05:17:16) Cancork Floor : You can use ANY thickness you want – in the floating floor options
(05:17:31) Cancork Floor : Again, “can use” translates multiple ways.
(05:17:41) Cancork Floor : The best way to go about this is to choose the PATTERN.
(05:17:49) Cancork Floor : The patterns often dictate thickness
(05:18:09) Cancork Floor : Not all of them duplicate.
(05:18:17) Visitor 40510907: I’m worried about it matching up to tile in bathroom in basement and carpet in bedroom in basemnet. Also have a door that needs to open and close
(05:18:36) Cancork Floor : Then a sample set is well worth the effort.
(05:19:02) Visitor 40510907: How do I get a sample set? is there a charge?
(05:19:25) Cancork Floor : Samples are ordered right off the website.
(05:19:33) Cancork Floor : for USA clients
(05:19:40) Visitor 40510907: ok thanks for your help
(05:19:41) Cancork Floor : for Canadian clients
(05:19:50) Cancork Floor : Which website are you on?
(05:20:06) Visitor 40510907:, I’m in US
(05:20:15) Cancork Floor : please click on the icork link above
(05:20:47) Cancork Floor : The cancork option won’t take zips
(05:21:00) Visitor 40510907: got it thanks
(05:21:34) Cancork Floor : The samples are free but the small cost to ship using USPS is charged. It calculates per 5 samples
(05:21:49) Visitor 40510907: thanks
(05:22:01) Cancork Floor : Anything else I can help with
(05:22:09) Visitor 40510907: no thank you

Can cork planks be used for a glue down installation in a basement bathroom?

(05:49:51) Visitor 25746827: Hi; Can bevelled edge cork planks be used for a glue down installation in a basement bathroom?
(05:49:59) Cancork Floor : No.
(05:50:17) Cancork Floor : Basement bathrooms are very tough to achieve using cork
(05:50:29) Visitor 25746827: Is there a particular technical reason?
(05:50:38) Cancork Floor : It takes plenty of preparation + plenty of water proofing and then it takes some more prep.
(05:50:43) Cancork Floor : when installing  cork tile in a basement, you first need to lay down a 6 mm vapor barrier sheet that will prevent moisture from seeping up through the slab from the ground below. Then you should install a plywood subfloor that will provide stability for the structure. After that, you can adhere the cork tiles directly to the plywood without having to worry about moisture from below.
(05:51:41) Cancork Floor : If the bathroom does NOT have shower or tub (so a powder room) then you can use a floating floor
(05:52:49) Cancork Floor : Or if you feel the shower will be used infrequently – only a few times per year. Then a floating floor can be used.
(05:53:09) Cancork Floor : Again, none of these options carry warranty…but you would certainly get many years of use out of them
(05:53:37) Visitor 25746827: Would cork tiles glued down over a polyethylene moisture barrier be different?
(05:54:34) Cancork Floor : The moisture barrier = inappropriate for tiles. It is fine for floating floor, but not allowed under glue down cork tiles
(05:55:12) Visitor 25746827: Thank you. Good day.
(05:55:46) Cancork Floor : The moisture barrier in a basement is the hardest to achieve under tiles
(05:56:13) Visitor 25746827: Thank you again.
(05:56:33) Cancork Floor : No problem…do you think this will be a heavy used bathrooms?
(05:56:38) Cancork Floor : bathroom*
(05:57:17) Visitor 25746827: Yes. Daily use, perhaps two showers.
(05:57:21) Cancork Floor : Ooppps
(05:57:51) Cancork Floor : The amount of effort to get a cork tile to stick (25years worth of ‘stick’) is tremendous. It is a little bit more work than a HIGH END porcelain tile.
(05:59:31) Cancork Floor : No problem. Please let me know if you are interested in your free set of samples.
(06:00:08) Visitor 25746827: I am in Toronto. Where do you ship from?
(06:00:19) Cancork Floor : Richmond BC = suburb of Vancouver BC
(06:00:26) Cancork Floor : Samples are free to Canadians.
(06:01:09) Visitor 25746827: Yes please, send the samples to
(06:01:19) Cancork Floor : Can you send an email |
(06:02:00) Cancork Floor : I will also need a list of the floors you are interested in.
(06:02:19) Visitor 25746827: I will do that momentarily. Thanks.
(06:02:36) Cancork Floor : Super. I look forward to gather them and shipping them.
(06:02:49) Cancork Floor : Do you have a colour-scheme in mind?
(06:03:09) Visitor 25746827: Just pulling that together now.
(06:03:34) Cancork Floor : OK…I’ll wait to see your request to see if there is anything else I can add for you.
(06:03:55) Visitor 25746827: Thank you very much.
(06:04:07) Cancork Floor : You are welcome. Good luck with the basement baths.

what is the IIC and STC ratings of Forna 6mm, 12mm cork underlay?


(06:25:10) Visitor 66090347: Hi, what is the IIC and STC ratings of your 6mm, 12mm cork underlay?
(06:25:20) *** Cancork Floor joined the chat ***
(06:25:31) Cancork Floor : Have Delta IIC ratings = much better
(06:26:10) Cancork Floor : The STC/IIC ratings are outdated and easily manipulated.
(06:26:34) Cancork Floor : The Delta IIC ratings are highly scrutinized and the “Gold Standard” for today’s building industry.
(06:27:00) Visitor 66090347: Ok thanks. What is the Delta IIC for these products?
(06:27:15) Cancork Floor : What type of floor is going over top?
(06:27:20) Visitor 66090347: laminate
(06:27:41) Cancork Floor : 12mm underneath 8mm Pergo (laminate) = 22 dB
(06:27:58) Cancork Floor : 6mm cork underlay underneath CORK floating floor = 20 dB
(06:28:07) Cancork Floor : 6mm cork underneath laminate = 11 dB or so
(06:28:59) Cancork Floor : The STC/IIC ratings are NOT convertible to Delta IIC.
(06:29:12) Cancork Floor : You cannot compare an STC of “72” to Delta IIC of 22.
(06:29:25) Cancork Floor : There are completely different tests with different outcomes.
(06:29:36) Cancork Floor : Are you looking to install in a Condo?
(06:31:58) Visitor 66090347: Yes. My condo requires cork underlay of IIC 71 STC 70. I can’t seem to find anything that meets this requirement. 🙁
(06:32:35) Cancork Floor : Those numbers are as outdated as Harvest Gold appliances
(06:32:44) Visitor 66090347: LOL
(06:32:46) Cancork Floor : How many stories to the building
(06:33:38) Visitor 66090347: 4
(06:33:45) Cancork Floor : wooden lowrise???
(06:33:49) Visitor 66090347: yes
(06:34:00) Cancork Floor : Sigh…this is why the numbers are sooooo out of date.
(06:34:18) Cancork Floor : The condo board is as old as the building = completely out to lunch on these numbers
(06:34:27) Visitor 66090347: LOL :)))
(06:34:39) Cancork Floor : Only a LUXURY highrise with 12 INCH concrete slabs can achieve “STC 72”
(06:34:56) Cancork Floor : If you don’t have the 12 INCH concrete you CANNOT achieve “72”
(06:35:01) Cancork Floor : It is a physical impossibility.
(06:35:26) Cancork Floor : Which a lawyer would eat this ordnance for breakfast…
(06:35:45) Cancork Floor : To get this, you would have to undergo “severe personal or financial hardship”
(06:36:10) Visitor 66090347: Sigh! I wish the council members have more knowledge about what they’re asking for…
(06:36:31) Visitor 66090347: yes totally agreed!
(06:37:32) Cancork Floor : You are welcome to show them the evidence…but that means becoming an acoustics detective and learning everything there is to know.
(06:37:56) Visitor 66090347: I’m too old to learn 🙁
(06:38:36) Visitor 66090347: Thank you Stephanie! I wish you were on the council board!
(06:39:21) Cancork Floor : Ok…You can point out that the 6mm is accepted by 90% of condos in Vancouver/Toronto, etc.
(06:39:43) Cancork Floor : Then you point out that the other 10% accept 12mm…but those condos are $1.6 MILLION or MORE!!!
(06:39:59) Visitor 66090347: Holy smokes!
(06:40:32) Visitor 66090347: I really appreciate your help, Stephanie! Thank you thank you!
(06:41:06) Cancork Floor : no problem…those are your biggest arguements = money.
(06:41:29) Visitor 66090347: yes precisely
(06:42:08) Cancork Floor : So long as you are UNDER the “luxury” condo market value, you have every right to ask them to update their mandate to state “6mm cork underlay or equivalent”
(06:42:11) Cancork Floor : It is simple as that.
(06:44:05) *** Visitor 66090347 has rated the chat Good ***
(06:44:41) Visitor 66090347: Super helpful and knowledgeable!
(06:44:59) Cancork Floor : Good luck. This is a battle I’ve helped win many, many times.

Can Cork Tiles be Installed over a Painted Concrete Floor?

(06:42:48) Visitor 92708909: Looking at cork floor for my bathroom
(06:42:57) Cancork Floor : Sure.
(06:43:00) Cancork Floor : Glue down cork tiles
(06:43:57) Cancork Floor : All glue down floor tiles are for bathrooms.
(06:44:26) Visitor 92708909: Would you recommend 8mm over 6mm?
(06:45:06) Cancork Floor : It is a personal choice.
(06:45:14) Cancork Floor : Have you seen samples?
(06:45:44) Visitor 92708909: I had installed the 6mm salami…on a painted concrete floor…Big mistake!
(06:46:21) Cancork Floor : yep.
(06:46:29) Visitor 92708909: I had a flood in my bathroom due to a clogged drain. The whole floor lifted up and bucked. Have to start all over
(06:46:38) Cancork Floor : Painted concrete is not allowed underneath these tiles.
(06:46:54) Visitor 92708909: I know NOW
(06:47:29) Cancork Floor : So how did you like the 6mm thickness?
(06:47:40) Visitor 92708909: it was fine.
(06:47:53) Cancork Floor : Are you looking for a thicker floor?
(06:50:17) Visitor 92708909: not really
(06:50:40) Cancork Floor : OK. Then you are welcome to stick with the 6mm in which ever pattern it comes in.
(06:50:51) Visitor 92708909: right. thanks
(06:51:11) Cancork Floor : We still have plenty of the 6mm Salami if you want to keep going with that.
(06:51:59) Visitor 92708909: ithat’s what I’ll do
(06:52:32) Cancork Floor : Sounds like a plan. Once the paint is removed, you will have a much better situation to work with.
(06:53:37) Visitor 92708909: How Loba 2K ultra do I need for about 110 sf?
(06:53:45) Visitor 92708909: how much
(06:53:53) Cancork Floor : 1 litre = 150sf of coverage.
(06:54:02) Cancork Floor : You will need 2 coats = 2 litres.
(06:54:02) Visitor 92708909: one coat?
(06:54:07) Visitor 92708909: ok
(06:54:13) Cancork Floor : No problem.
(06:55:39) Cancork Floor : Anything else I can help with?
(06:56:16) Visitor 92708909: i’m good. thanks
(06:56:48) Cancork Floor : OK…remember the adhesive as well. 1 gallon Wakol D3540 lays 170 – 180sf of cork = just about perfect for your project.
(06:56:53) Cancork Floor : ‘Bye.
(06:57:08) Visitor 92708909: bye
