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.

For easy transport and installation, Knauf Brio boards are 600 x 1,200mm – weighing 22–30kg, depending on their type. There are four Knauf Brio boards: Brio 18 (standard 18mm thick), Brio 23 (reinforced 23mm – recommended for underfloor heating applications), Brio 18WF and Brio 23WF (composite boards with an additional 10mm laminated wood fibre layer providing high mechanical load resistance and effective footfall sound insulation).

Installing Knauf Brio boards is incredibly simple and fast – no special skills are required for a perfect job. The precise tiered edges are glued with Knauf Brio Joint Adhesive and then screwed together to ensure a solid bond. Because it is so quick to lay, Knauf Brio saves valuable installation time – and the new floor can take traffic as soon as the glue has hardened, typically a matter of hours.

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. Knauf Brio has impressive thermal transmission coefficients: standard units – 0.05-0.08 m2K/W.

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 Brio is also much lighter than traditional wet screeds, significantly reducing loads and costly structural requirements in multi-storey buildings.

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.

Knauf Drywall manufactures a full range of plasters, plasterboards, insulating laminates, drywall accessories, metal sections and steel building systems, for domestic and commercial applications. Recently Knauf Drywall introduced the UK industry’s first carbon neutral plasterboard, Knauf Futurepanel. Knauf Drywall also actively promotes recycling from building sites and has a zero waste policy in its energy efficient factories at Sittingbourne in Kent and Immingham on Humberside.
