Fire Barrier Curtain (FB30)

Fire barrier curtain FB30, a 1mm thick x 1220mm wide reinforced glass cloth curtain impregnated with an intumescent coating.

• Available up to 40m long rolls. Very robust material, ideal for drop curtains up to 10m.
• FB30 is also suitable for affixing to a range of surfaces and structures, such as steel, trunking, wood, and concrete.
• Provides effective fire protection against the spread of flame, insulation, acoustic protection, and also smoke sealing.
• Also non-fibrous and dust-free, ideal for clean rooms, hospitals, and computer suites.

Additionally, for greater fire protection between floorboards and secondary floors, use fire barrier curtain horizontally over a suspended ceiling. Furthermore, use in conjunction with Envirograf® Product 13 or Product 16 to provide an effective penetration seal.

In addition, an acoustic version, FB30/AC, is available to meet airborne and impact sound reduction, meeting requirements of Document E of UK Building Regulations. FB30/AC has a 13mm acoustic sponge adhered to the cloth. For greater acoustic properties, a sponge up to 20mm can be used. For additional insulation, see Product 54 Insulated Fire Barrier Curtain.

Application Instructions

All curtains are supplied with sufficient adhesive for the 50 mm overlap. The adhesive can be applied to
one face and pressed together, although it is best to apply a small layer to each face and apply
together, giving a much quicker bond. Just hold together for approximately 1 minute, to allow the
adhesive to grip. 1 litre of Adhesive is sufficient for 50 metres of curtain.
Should the Curtain be installed in a windy area, Envirograf ST50 or ST75 Class 0 Adhesive Tape can
be applied over the glued joint to hold it more securely while the Adhesive dries.
For fixing the top, bottom and ends of the Curtain; for timber supports use Envirograf FB/T Battens,
fixed through to the timber with 30 mm large head clout nails. For concrete, block or brick fixing, use
FB/C Metal Straps – 25 mm wide, with 2 mm holes every 300 mm apart. These can be fixed with spit
nails, screws, pop rivets (steel) or self tapping screws to the steel work.
Where cutting around services is required;
1. Wrap around the service with a section of the curtain and adhere together using the adhesive.
2. Cut a cross – X – in the barrier to allow the service through. Once the service is wrapped,
adhere the cut area of the curtain to the wrapped service.
3. If necessary, fit a patch over the curtain with the adhesive, using a section of curtain as the
patch.
