Knauf's new Brio Screed Board simply floors them!
New Brio Dry Floor Screed from Knauf Drywall is the ideal base for a perfect floor in new or refurbished residential and office buildings. A state-of-the-art gypsum fibre board with a precision tiered edge, Knauf Brio is light and narrow – and it provides a strong, durable and flat surface. Its excellent thermal transparency makes this latest addition to the Knauf Drywall Product Portfolio the perfect screed for use over underfloor heating and cooling systems.
Knauf Brio is a lightweight gypsum fibreboard with precision engineered tiered edges. The boards are 1,200 x 600mm for ease of handling and installation. They are laid directly over an underfloor heating array of routed polystyrene containing the pipes and supporting diffuser trays, or over the subfloor. The Knauf Brio edges are glued, then screwed together. This fast-lay flooring can take traffic as soon as the glue has dried – just a matter of hours, and much sooner than wet screeds.
For underfloor heating applications, Knauf Brio is available in a 23mm thickness. For use without heating systems, Brio comes in 28mm and 33mm overall thicknesses, with a sound absorbing 10mm wood fibre laminate on the underside. Depending on their type, Knauf Brio boards weigh just 22–30kg/m2. By comparison, a traditional site-mixed sand and cement screed, 60mm deep to provide 30mm cover over underfloor heating pipes, weighs about 110kg/m2. The potential weight saving is approximately one ton for every 11.5m2, making Brio an ideal choice for reducing structural loads in tall buildings – and existing buildings that upgrade to underfloor heating.
Knauf Brio is thermally transparent, making it incredibly efficient for use with underfloor heating systems. Temperature changes are achieved almost immediately – so there’s no premium to pay for heating up a mass of concrete before the environment starts to feel warm.
The low installation thickness makes Knauf Brio ideal for refurbishments – and the total height of 23mm means you can install a highly efficient underfloor heating system for a total loss in room height of just 50mm.
Knauf Drywall Marketing Manager Bob Stark says the Brio Dry Floor Screed System has many real advantages over traditional wet screeds and timber decks. “The main benefits are better stability, the speed and ease of installation, and higher quality. In addition, Knauf Brio can take high loads, yet it retains its elasticity – bowing is simply not an issue. It is non-combustible and is classified as Building Material Class A1.”
Brio Dry Floor Screed is available from distributors and builders merchants, and comes with a range of accessories including Knauf Brio Joint Adhesive, Knauf Brio Screws (17 and 22mm), Knauf Edge Strip, and Knauf Levellers for correcting uneven substrates.
