British Gypsum Glasroc X is a high performance sheathing board providing six months' weather protection as certified by the BBA, making it a reliable alternative to cement particle boards
External sheathing boards are designed to make buildings watertight prior to the completion of a façade. This means that not only is the building frame itself protected from the weather but internal trades, such as dry liners and heating engineers, can progress with their installations and avoid expensive delays.
British Gypsum's new high performance Glasroc X external sheathing board provides weather protection for most external façade systems used in steel frame construction. It is the only gypsum-based sheathing board with full BBA certification verifying its weather protection performance in its own right, rather than as part of a system.
It has many practical installation benefits, including being 35 per cent lighter than cement particle boards, making it easier to handle and install on site - especially important when contractors are working at height. The new sheathing board is also easy to score and snap – similar to plasterboard – with no need for specialist cutting or dust extraction equipment.
Glasroc X sheathing board was first specified on the Bupa and Richmond Villages' Wood Norton retirement development near Evesham in Worcestershire, due to open in spring 2019. Kieran Boxwell, operations director at sub contractor CG Reynolds, said: 'Wood Norton is one of the first projects in the country to use the Glasroc X sheathing board. It has been easy to handle on site because it's lightweight and easy to cut. However, it was the six months' BBA certificate for temporary weather protection that gave me confidence in using the product.'
The new external sheathing board and its associated accessories were also specified on University Centre Shrewsbury's The Tannery student accommodation and retail complex in Shropshire. Calvin Challis, quantity surveyor at sub contractor V&D Interiors, said: 'As Glasroc X is faster to install, fewer people are required to complete the job. Using an alternative product would have taken around 25 to 30 per cent longer.'
