Dry Floor screed faster and more stable than wet screeds and decking

Suitable for newbuild or refurbished residential and commercial buildings, Brio Dry Floor Screed offers many real advantages over traditional wet screeds and timber decks such as better stability, the speed and ease of installation, and higher quality. It creates a robust and monolithic floor with excellent loading.

This gypsum fibre board is virtually thermally transparent, so it works well with underfloor heating systems offering responsive heating at low running cost and with lower CO2 emissions. So there’s no premium to pay for heating up a mass of concrete before the environment starts to feel warm. Knauf Brio has an impressive thermal conductivity of 0.38 W/mK.

The panel is also ideal for refurbishments because of its low installation thickness of just 23mm, which allows for the installation of an underfloor heating system for a total loss in room height of just 50mm. Knauf Brio is also much lighter than traditional wet screeds, significantly reducing loads and costly structural requirements in multi-storey buildings.

There are four Knauf Brio boards: Brio 18 18mm thick), Brio 23 (23mm – recommended for underfloor heating applications), Brio 18WF and Brio 23WF. The Brio WF (wood fibre) products are specifically developed to be an effective floor treatment as part of an acoustic separating floor, and an instant upgrade in refurbishments.

They are composite boards with an additional 10mm laminated wood fibre layer that provide high mechanical load resistance and effective footfall sound insulation and remove any need for acoustic battens.

Installation is both simple and fast, with no special skills required. The precise tiered edges are glued with Knauf Brio Joint Adhesive and then screwed together to ensure a solid bond. Once the glue has hardened the new floor is ready to take traffic - typically a matter of hours. All Brio boards are non-combustible and classified as Building Material Class A1.
