Cork Underlayment

  • Why cork underlayment?

Cork underlayment is a wonderful eco-friendly underlayment option that helps to add warmth underfoot as well as sound reduction properties. Popular for use in condos and commercial properties, cork is naturally mold and mildew resistant and allows air to flow freely through the floor system.

Do I REALLY need underlay?

  • Yes, most definitely.

Underlayment is an amazing invention created by the flooring gods out of necessity. Underlay has an impressive list of benefits, including: adding warmth to your floors so your feet aren’t so cold on new tile flooring, adding comfort and a slight ‘give’ underneath wood or vinyl floors, reduced sound transmission (great for houses with noisy teenagers!), as well as reducing in room step noise. The image to the left is a very simplified example of using underlayment versus not using it, but as you can see the benefits greatly outweigh any reason not to.

Making your house a home

  • Products that work together

Cork underlayment is popular for use underneath of ceramic and porcelain tile flooring, hardwood floors, vinyl floors, and laminate floating floors. Cork underlayments is really quite versatile and can be used underneath all floor types.


  • What does it mean?

Underlayment with a thickness of up to 5mm thick are great when it comes to residential or commercial use, with all flooring types. When you get to more than 5mm thick, these are really great for installations where you need to add thickness to match up with an adjoining/existing floor surface.
