Cavity Barrier protecting new development of timber frame studios.
Situated on the former site of St. Albans’ Oaklands College, this multi-phase project was to both refurbish the existing residential properties and to deliver a new development of timber-framed studios, one and two bedroom flats.
The project was conceived and is being directed by property development firm Nicholas King Homes, following designs by chartered architects MGM Associates.
The first phase, the renovation of the existing blocks of apartments, was completed in 2010. The completion of the currently-underway second phase of this project, dubbed “Oaklands II”, will see the Oaklands site given a new lease of life.
On-site application of Envirograf® Product 55 is being carried out by Cygnum Timber Frame, following consultations with our technical team, ensuring that the timber-framed buildings will not only meet, but exceed, Building Regulations.
Envirograf® Product 55 FB/TS (free-air-flow cavity barrier) is being used in the construction of the new, timber-framed second phase of the development. Consisting of 1-metre lengths of non-fibrous sponge faced with an intumescent strip, the barrier is also coated with a protective sleeve, making it fully resistant to condensation and moisture. Usable in both party floors and party walls, the product is incredibly easy to attach, using a high-tack self-adhesive tape affixed to the fixing side.
Product 55 FB/TS has been tested to both BS En 1363-1 1999 and BS476 Parts 20/22 (1987), achieving up to 142 minutes fire resistance and integrity. This is of particular importance as the product is designed to be used with timber party walls and floors, which are required to offer fire resistance from below matching that of the connected walls. It is of the utmost importance that the product is fitted correctly, and as such it can be easily cut to size to fit smaller gaps or corners.
