Description
Underfloor Fire Barrier and Acoustic Barrier
Underfloor fire barrier UF60 (60 minutes) is made from graphite-impregnated cloth covered with reinforced kraft paper, giving 60 minutes of fire and insulation protection. UF104 is similar but has a wire mesh inside the unit as added support, approximately 5mm thick. Designed to provide insulation and fire protection to the flooring as well as ceilings. Additionally, it can also help improve the support of wooden flooring.
For the acoustic requirement to U value and to meet the requirement of Document E (H in Scotland), there is a 40mm thick sponge supplied for the width between the joists. Lay this over the barrier between the joists.
Standard lengths are 1800mm long. Standard widths are 400mm, 450mm, 500mm, and 600mm. Other lengths and widths are available to order. The barriers are very strong. But with a sharp knife, you can cut where there are herring box joints. Use all of the supplied metal plates when fixing the barrier in position.
- In testing, the UF104 barrier was installed in a ceiling/ floor without any plasterboard or lath-and-plaster. Just the barrier itself. It tested to BS476 part 21 (1987), achieving 104 minutes of integrity, insulation, and load-bearing.
- UF60 tested to BS476part 21 and achieved 62 minutes.
