Knauf Brio Dry Floor Screed is a substrate for floors in new build and refurbishment projects that not only cuts construction times but also boosts both thermal and acoustic performance, while scoring on the sustainability front according to Knauf. <br> <br> Developed by Knauf Drywall – the UK's manufacturer of lightweight building products and systems – Brio is an engineered gypsum flooring panel that has a high thermal conductivity (R = 0.38) so heating response times are quicker and energy use is reduced. When used in place of chipboard, Brio increases underfloor heating system efficiency by between 36% and 43%, the company claims.<br> <br> Once installed, Brio creates a robust monolithic floor with a high density of 1,100 Kg/m3 and so cuts both impact and airborne sound transmission, while its low profile minimises the impact on floor-to-ceiling heights so it can meet Part E of the Building Regulations, Knauf explains.
