    When Therm-A-Sol is subjected to a fully developed fire the intumescent material produces a mass of incombustible heat resistant foam that is like glass.

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

    • Used as a concealed fire seal behind timber lippings
    • Sealing gaps between fire resisting doors and frames

    For ease of installation it has a self – adhesive tape allowing rapid installation for any application.
