Application

Gypsol TimBRE screed is a free-flowing and self-compacting liquid screed that you can use in various applications, including both commercial and domestic projects. Customers use the product to produce a smooth, flat, and level floor to form the subbase for subsequent floor coverings for internal floors in a large variety of constructions where they form the substrate using timber.

Customers are specially trained screeders who use specialized equipment to pump the screed into place. Because Gypsol TimBRE offers a concrete feel to a timber floor, it eliminates issues with creaking and imparts excellent acoustic and thermal properties to the floor.

Description

Gypsol TimBRE screed is designed and independently tested for use in acoustic and non-acoustic flooring systems which use timber joists as their primary supporting structure.

Gypsol Binder screed is an integral component of Gypsol TimBRE, a liquid screed suitable for use in both residential and commercial projects with a timber substructure. It can be used with or without underfloor heating and can be used to enhance the acoustic performance of the floor to meet or exceed Part E of the UK building regulations. Gypsol TimBRE screed is non-combustible and can offer a creak-free, concrete feels to a timber-supported floor. Gypsol TimBRE is approved for use in the SoundBar® system.
