Sound-control answer

Cork for floor and wall sound control

Cork can support sound-control projects when the product matches the problem: underlayment for floor impact sound, wall panels for room echo, and realistic expectations for the full assembly.

  • Compare 3mm, 6mm, and 12mm cork underlayment for floor assemblies.
  • Compare cork wall panels when the room needs decorative acoustic surfaces.
  • Ask a specialist before promising sound ratings or ordering full boxes.

Cork Soundproofing and Sound Control

Concrete building floor soundproofing

The 12mm (½”) cork underlay has been tested and found to absorb 48 dB of noise and 6mm (1/4”) cork underlay absorb 23 dB of noise.  This is the number that can be ADDED to your subfloor’s calculated rating of (assume 27 dB).  The final assembly rating depends on your building’s existing structure; the per-product acoustic test statements are linked from each product page.  If you work with a cork floating floor (19dB) over top of the 6mm cork underlay (23dB), you can add (with confidence) 42 dB worth of acoustic insulation (19 dB + 23 dB, per the individual product test statements).

Wood-frame building floor soundproofing

If you have a wood-frame building, the floor/ceiling will only offer 25 dB worth of insulation. It is very difficult go get sound barrier standards 72dB (most HOA requirements about flooring/soundproofing) if you use a laminate flooring with cork underlayment, such as Pergo laminate is a NEGATIVE number (-6 dB) which means it INCREASES noise in the space AND INTO the spaces next to it (your neighbours).

We will recommend you order cork underlayment with Forna cork floating flooring. With 6mm underlay (23dB) + 12mm floating floor(19dB) = 42dB of acoustic improvement. Or 12mm underlay (48) + 12mm floating floor (19dB) = 67 dB. These are the per-product tested improvements; the final assembly rating depends on your building’s existing floor and ceiling structure.

Flooring
  • 12mm Foran Cork Floating (19dB)
  • 10mm Foran Cork Floating (19dB, tested at 11mm)
  • 10.8mm Fusion Cork Floating (18dB)
  • Engineer hardwood (0dB)

  • Pergo laminate NEGATIVE (-6 dB)
Underlayment
  • 1/2″ cork underlayment (48dB)
  • 1/4″ cork underlayment (23dB)
  • 1/8″ cork underlayment (12dB)
 
 
 
Building Structures
  • 12″ concrete slab (54dB)
  • 8″ concrete slab (36dB)
  • 6″ concrete slab (27dB)
  • 2.5″ concrete slab (12dB)
  • Wooden subfloor (25dB)
Ceiling

Your floor’s calculated rating:

Eg. Cork flooring (19 dB) +1/4″ cork underlayment (23dB) + 6” Concrete slab (27 dB)
Eg. Engineer hardwood (0dB)+ 1/2″ cork underlayment (48dB) + Wooden subfloor (25)

Choose cork for sound control projects

Sound-control visitors need the right path for the problem: cork underlayment for floor impact sound, cork wall panels for room echo, samples, and realistic project guidance.

Frequently asked questions

Can cork help with sound control?

Cork can help with sound-control projects when the right product is matched to the problem: underlayment for impact noise and wall panels for reflected room sound.

Is cork underlayment enough to soundproof a floor?

No single flooring layer guarantees soundproofing. Results depend on the full assembly, building structure, thickness, installation method, flanking paths, and project requirements.

Should I choose cork underlayment or cork wall panels?

Choose cork underlayment for floor impact sound planning and cork wall panels for decorative acoustic surfaces that help soften room echo.
