Timloc Thermo-Loc FRstop Fire Rated Cavity Stop Sock For 210mm Cavity

The Timloc Thermo-Loc FRstop Fire Rated Cavity Stop Sock is a non-combustible, thermal and acoustic cavity insulation solution that prevents the spread of flames within exterior masonry and reduces the effect of noise pollution. Manufactured using lengths of low-resin, fire-resistant Rockfibre mineral wool that will provide 1 hour of fire integrity and minimum 15 minute insulation. 

FRstop is designed to friction fit within the cavity and is easily installed both vertically and horizontally into the cavity during construction. Take care to ensure butt joints are closely fitted and the cavity sock fully fills the cavity.
