insulated underlay

Insulate EVA Underlayment

Product Code:

Insulated underlay creates a thermal barrier on a concrete substrate and your finished floor. When installing floor heating on a concrete substrate we highly recommend as it is inexpensive, easy to lay and provides significant operational savings. Note: There are insulation boards available for this purpose but they are very expensive and overkill!

Insulated underlay is extremely durable and will withstand repeated stress. The mat will not shrink, absorb moisture or rot. Insulate has not been tested or approved as a sound reducing application but it does offer high impact and sound reducing properties. 

    • 5 times faster to install than compressed sheet.
    • 20 times lighter than compressed sheet.
    • High 33% reduction in impact & sound.
    • Increases insulation values & performance by 37%+.
    • Easy to cut.
    • Peel & stick (no nails or screws required)
    • Approved Installer 10 year Manufacturer’s warranty.
