Resilient 250

Resilient 250 is a high performing acoustic resilient layer that has been designed to significantly reduce impact sound. It can be used as used as a Soft Floor Covering or as an Acoustic Underlayment.

Why Resilient 250?

Resilient 250 is quick and easy to work with and can be used with a wide range of floor coverings, providing exceptional acoustic performance to the finished installation. Being manufactured from sponge rubber, it provides long-lasting durability and strong resistance to foot traffic, prior to the floor covering being installed. Resilient 250 exceeds the requirements for a Soft Floor Covering in Approved Document E (England & Wales), Technical Booklet G (Northern Ireland) and Section 5 of the Building Standards in Scotland.

Resilient Applications

Resilient 250 is widely used in developments where high levels of acoustic performance are required. It is therefore used in applications requiring compliance with Approved Document E – Floor Type 1 (concrete base with ceiling and soft floor covering). It must be bonded to the subfloor to comply with Approved Document E.

Installation Points to Note

Full installation guidelines can be downloaded below.

Installation Instructions Download
The area of installation must be dry, smooth, dirt and dust free and weather tight.
The subfloor must be sound and sufficiently level, with no imperfections protruding through Resilient 250. If not, then a self-levelling screed may be required.
When bonding to bare concrete, a suitable concrete sealer is recommended to ensure maximum adhesive coverage and bond strength
If moisture levels exceed 75% RH, seal the area with a suitable primer.
Sonixx SX900 adhesive should be used to permanently bond Resilient 250 to the subfloor.
Where possible, the skirting board should be installed above Resilient 250, in order to reduce flanking sound transmission.
When installing ceramic tiles, stone and vinyl flooring, leave at least a 3mm gap around the perimeter, which should be filled with a flexible sealant.
