The Envirograf FB30 Fire Barrier Curtain provides up to 30 minutes fire protection to steel and wood trusses and fits between concrete soffits and suspended ceilings. As the curtains don't shed fibres, they are ideal for use in clean spaces and areas such as hospitals, laboratories and computer rooms. Simply cut with a sharp knife; openings in the barrier curtain can be made for access fire doors if required.

An acoustic version (FB30/1220/AC) of the curtain has 15mm-thick sponge for extra sound absortion, meeting the airborne and impact sound reduction requirements of Document E of UK Building Regulations. If more insulation is required see Envirograf® Product 54.

The curtains can also be laid horizontally flat over a suspended ceiling for more fire protection, using one FB/CLIP3 every 500mm, and between floorboards and secondary floors. Services can be passed through in conjunction with Envirograf® Products 13 and 16.

At 1200mm wide, the curtains can be overlapped by 50mm and sealed using the included adhesive. a 310ml tube of IA intumescent water based adhesive (product 46) is supplied with each order of up to 10m, with additional tubes for every additional 10m length or part thereof.

Rolls of the fire barrier curtain can be provided up to 40 metres long. Contact our sales team 0113 245 5450 if these are required.

Application

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 PVC pipes, cables, services, etc., pass through the curtain, refer to the Application Guide in our downloads section for more and continued information showing the use of our FB/C Battens and our Economy Boxes (product 16).

Examples of use

An authentic African village, built in the grounds of Christian conference centre Sizewell Hall, allows school children to learn about the problems of sourcing water, food, and other everyday essentials that a third-world country faces every day. The thatched roofs of the village huts posed a considerable fire risk to the volunteers that run the centre and required a fire barrier be used under the thatch for up to 30 minutes of fire protection.

Half of the Fengate Greyhound Stadium, according to Peterborough’s The Evening Telegraph, was saved due to a fire curtain, in a fire that took six hours to bring under control.
