What Is the Best Underlay for Floating Floors?

If you are installing a floating laminate floor or floating engineered timber floor, then you will be required to install prior to the floor being laid a foam or rubber underlay. A minimum of 3mm underlay is recommended by Imperial Flooring Australia. Underlay and subfloor types are the most important aspect of any flooring project in both residential and commercial spaces. Proper selection and installation of underlays and subfloors is crucial to the proper wear and stability of any flooring type, especially when it comes to acoustic performance.

What is Flooring Underlay?

Floating floor underlay is a layer of foam or rubber that protects your floors. It is installed between the subfloor and the floating floor that acts as an insulation that will both dampen sound (acoustics) and protects your beautiful floors from mould, mildew, and any potential moisture.
