Application

This free-flowing and self-compacting liquid screed produces a highly efficient heating system with a co-efficient of performance some 25% higher than competing sand cement screed systems. The screed is independently third-party verified for the thermal conductivity of up to 2.5 W/mK.

Screed will give you a surface finish which is:

Smooth.
Flat.
Level.

Therefore, it forms a subfloor for tiles, vinyl, laminate, or any other floor covering for internal floors.

Specially trained screeders using specialized equipment pump Gypsol HTC into place. Screed can be applied thinner than other flowing screeds because it requires just a 20 mm cover to any underfloor heating pipes/cables. Improves overall diffusivity and offers unrivaled thermal performance.

Description

Gypsol HTC is specifically formulated for use with underfloor heating and cooling systems. It suitable for both warm water and electric underfloor heating.

Gypsol Binder is an integral component of Gypsol HTC, a screed specially formulated to allow thinner depths than other Gypsol liquid screeds, allowing just a 20 mm cover to heating conduits. Gypsol HTC is designed to offer high thermal performance in conjunction with underfloor heating and cooling systems. Gypsol HTC is suitable for all types of floor covering, including traditional tiles, carpets, vinyl, and wood floors.
