Yes. For floating floor application, Evalay 3mm underlay plus a 200-micron black plastic must be installed.

Acouslime adhesives and moisture seal are suitable for use on heated slabs.

Evalay Underlays and Acouslime Adhesives are suitable for use on the following substrates:

• Concrete slabs
• Existing timber flooring
• Chipboard or particleboard
• Plywood
• Ceramic tiles
• Marble
• Cured levelling compounds
• Heated slabs

As a general rule, density is more important than thickness, particularly. For under carpet, a thicker underlay offers good cushioning and softness underfoot.

A denser underlay provides superior insulation and acoustic performance in both carpet and hard flooring applications. Under carpet it can also reduce flattening or indentations left by heavy furniture or high traffic areas.

It depends on the type of flooring. Residential broadloom carpet requires underlay whereas commercial carpet tiles are generally glued down or looselay so do not need underlay.

Laminate flooring must have an underlay, while engineered timber only needs underlay if installed as a floating floor. If timber is glued down then no underlay is required.

Hybrid flooring already has the underlay attached to the boards and it is not recommended to use additional underlay.

Most vinyl flooring does not need underlay as it is usually glued down.

There is the option to install glued down underlay under some types of flooring to provide better acoustic performance and insulation. This should be discussed with the retailer or manufacturer to insure underlay is fit for your purpose.
