Excel have supplied GB Solutions and the sub-contractor, Roseville Plastering, with Knauf Brio flooring to enable a moisture-free floor screed for the timber-frame scheme.
The outstanding acoustic performance of Brio flooring led to it being chosen for The Green development. Knauf Brio 18WF, an 18mm gypsum fibreboard with a 10mm laminated wood fibre layer, provides a 50dB sound insulation – a full 5dB above the standard Part E Building Regulations. The interlocking boards are proving to be both cost-effective and easy to install between floors in the development’s 34 town houses and 101 apartments, particularly in comparison with a wet screed system. The student village has been designed based upon sustainable principles and is one of only 15 buildings in the world with an ‘Outstanding' BREEAM classification.
Providing a strong, durable and flat surface, Knauf Brio Dry Floor Screed can be specified either as an acoustic solution variant or as a dry screed with excellent thermal transparency for use over underfloor heating and cooling systems. Dave Taylor, Roseville’s Floor Screed Operations Manager, stated:
“Brio passed our on-site acoustic trials with flying colours and we find the tiered edge boards very easy to install. We can also work around other trades more easily – if there is a hold up with other trades in a particular area we can just leave Brio boards mid installation and start working somewhere else. But once you’ve started laying a wet screed you have to keep going until the floor is finished.”
