A self-compacting flowing screed for acoustic and non-acoustic flooring systems.
Application
It is specifically intended for use in acoustic and non-acoustic flooring systems which use timber joists as their primary supporting structure.
The product can be installed on separating floors that include:
- Minimum 240 mm engineered 'I' joist.
- Minimum 18 mm oriented strand board (OSB).
- Approved acoustic resilient insulation.
- Polythene separating layer (500 gauge minimum).
- Optional underfloor heating elements.
- Supaflo TimBRE screed.
The product can be used with either warm water or electric underfloor heating systems in both commercial and residential developments. Its use will help to improve the acoustic performance of the floor to meet or exceed the requirements set out in Building Regulations Approved Document E.

The screed will also improve the environmental, fire resistance and durability characteristic and provide timber supported floor that feels like concrete.
Designed to be used in conjunction with a resilient acoustic insulation layer.
Features and benefits:
- The product is delivered to site ready mixed.
- Forced drying: Can be forced dried after seven days using the underfloor heating system or temporary dry source heater or dehumidifiers. Forced drying will reduce drying times.
- Volatile organic compound (VOC): Virtually zero.
