THERM-A-FLEX is a general purpose intumescent material offering the qualities of a high expansion foam with a firm pressure to provide the qualities required of an ideal intumescent material for most applications. The product is designed to withstand a full range of environmental conditions, allowing it to be used in either open or concealed situations without special protection. The flexible nature of the material also permits it to be used for many applications where a rigid strip would be impractical.
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
• sealing services into walls or even for sealing voids within services
THERM-A-FLEX is formulated from a unique chemical formulation based upon
expandable graphite in a binder that allows the material to flex at normal room
temperatures. This flexiblility reduces as the temperature nears freezing point. It is not recommended that the material is used at temperatures below 5ºC.
THERM-A-FLEX is supplied in its natural black* finish which because of its resistance to both atmospheric moisture and carbon dioxide, requires no additional protection. The material may be decorated with a wide range of conventional finishes without impairing its performance.
