Features & Benefits

• General purpose intumescent material
• Offers the qualities of a high expansion foam with a firm pressure to provide the qualities required of an ideal intumescent material for most applications
• Designed to withstand a full range of environmental conditions
• Can be used in either open or concealed situations without special protection
• Flexible nature of the material also permits it to be used for many applications where a rigid strip would be impractical

Installation

Therm-A-Flex has been developed for general sealing applications but it is particularly suited for the following type of installation:

• Sealing gaps between elements of construction
• Sealing gaps between fire resisting doors and frames, shutters, windows and the adjacent walls
• Sealing services into walls or even for sealing voids within services

Recommendations on the amount of THERM-A-FLEX necessary for the above applications cannot be made, because this will vary according to the size of the gap or void, the nature of the bounding materials, and the period of fire resistance required.

Testing

Therm-A-Flex meets the requirements for fire and smoke performance of BS476 : parts 20, 22 & 31.1 . It has also passed the more exacting standards required by Certifire.

It is currently being evaluated to the requirements of BS EN 1634-1.
