RubberLay 65 Under Screed Resilient Layer
InstaCoustic RubberLay 65 is a high performance resilient membrane designed to reduce the transmission of impact sound through floor screed
Applications
- New build
- Change of use
- Under screed
- Concrete floors
Benefits
- Exceeds Building Regulations performance standards
- Significantly reduces impact sound transmission
- Longevity of performance due to removing possible creep or collapse under high loads
- High stability – creates a very stable resilient membrane which reduces the risk of settlement and prevents screed failure
- Strong and durable layer that is resistant to damage before the screed is laid preventing points of contact with the structure leading to sound test failures
- Suitable for use with under floor heating

System Detail Illustration
Perimeter Detail Section
Please note that it is critical that the perimeter detail is applied consistently throughout the contruction process. Failure to isolate the perimeter edge of the screed will create points of contact with the structure that will result in flanking transmission of sound. The wall lining and the skirting board also require isolation from the screed to avoid flaking sound transmission. Failure to follow this detail could compromise the sound insulation performance.
Under Floor heating
Under floor heating systems can be applied within the screed application. However, it is critical that no fixings of any sort penetrate the resilient layer or create any direct points of contact between the screed and the structural floor. If the under floor heating system has an insulation layer, on which the heating pipes are installed, this can be laid directly on top of the resilient layer but not penetrate this layer.
Consult the underfloor heating manufacturer to check the minimum screed depth to cover the heating system.
