4 Introduction Timber frame construction is well established in the UK, and British Gypsum products are extensively used to form the internal elements. Internal partitions and walls can be used in both new-build and refurbishment. Gyproc plasterboards are used to line the timber stud framing, whilst Isover insulation products can be used to improve sound, fire and thermal insulation even further. External linings are based on a structural timber frame and can be lined with Gyproc plasterboards to form the internal lining. Floors and ceilings combine Gyproc plasterboard ceilings with Gyproc flooring solutions to provide the required impact and airborne sound insulation, as well as the necessary fire resistance. Again, Isover insulation can be used to improve the thermal and sound insulation. Roofs can be underlined with Gyproc plasterboards and Isover insulation for good sound and thermal insulation. Cavity barriers comprising British Gypsum Gyproc / Glasroc and Isover products can be specified for concealed spaces in the structure or fabric of the building in order to satisfy national Building Regulations requirements for providing suitable cavity barriers and fire-stopping. Whilst timber frame is a form of lightweight construction it has good inherent strength with a lower overall dead weight than masonry, and it is not uncommon for buildings to be built up to seven storeys with timber.

NB Separating floors require both a suitable isolating floor and a suitable isolating ceiling. NB The fire resistance and sound insulation performances are for imperforate partitions, walls and ceilings incorporating boards with all joints taped and filled, or skimmed according to British Gypsum s recommendations. The quoted performances are achieved only if British Gypsum components are used throughout, and the company s fixing recommendations are strictly observed. Any variation in the specifications should be checked with British Gypsum. NB Where boards are fixed direct to timber joists, Drywall Timber Screws should be used as opposed to nail-fixing to minimise the risk of fixing defects occurring. bgtechnical.enquiries@bpb.com 0
