ISO-SCREED FOAM (Part Code A335 / A340)

Iso-Screed Foam is a 5mm foamed polyethylene layer of 33Kg/m³ density. Used in conjunction with the appropriate floor materials it meets Approved Document E requirements for an underscreed resilient layer. Giving added value of water resistance. It can also protect the mineral wool during screed laying.

ISO-SCREED significantly reduces impact noise and vibration under floor screed as well as providing a degree of airborne and thermal insulation.

This product can also be used on top of a concrete floor especially if the floor has failed an impact sound test. If the product is bonded down impact improvements in the order of:
Impact Sound Improvement Index ISO Method 140 part8 - Delta Lw.34dB
can be expected.

Acoustic Resilient layer for under screed isolation UK


Section 3.65 of the Building Regulations (Approved Document E) states that the resilient material should meet the following two requirements:

1. A maximum dynamic stiffness (measured in accordance to BS EN 2905201:1992) of 15MN/m³
and
2. A minimum thickness of 5mm under the load specified in the measurement procedure of BS EN 29052-1:1992, 1.8kPa to 2.1kPa.

ISO-SCREED meets both these requirements.

In any construction height is a significant factor. This material is designed to ensure maximum performance whilst minimising height rise of the construction.
