Description

Gypsol TimBRE self levelling anhydrite screed is made to exacting standards by quality assured manufacturers to BS EN 13813. It is a combination of high quality Gypsol binder, specially selected sands, water and special additives where required. It is designed specifically for use in acoustic and non-acoustic flooring systems which use timber joists as their primary supporting structure.

Gypsol TimBRE self levelling anhydrite screed is suitable for the encapsulation of an underfloor heating system, either electric or warm water. Gypsol TimBRE self levelling anhydrite screed is suited to both residential and commercial and will help to improve the acoustic performance of the floor to meet or exceed Part E of the Building Regulations (E&W). Gypsol TimBRE self levelling anhydrite screed also improves the environmental, fire resistance and durability characteristics and gives a concrete feel to a timber supported floor.

Gypsol TimBRE self levelling anhydrite screed is designed to be used in conjunction with a compressible or an acoustic resilient insulation and an acoustician should be consulted to approve the design prior to installation where acoustic performance is required.
