The Thermo-loc FR by Timloc is a rigid profile extrusion that has a 30-minute fire rating. These cavity closers provide effective DPC and thermal barriers between the outer wall leaf and the inner frame. The rigid profile extrusion allows for both a first and second fix making it suitable for all frame and sill positions. This also makes the Thermo-lock FR durable and resistant to decay.

The Thermo-loc FR has a thermal conductivity of 0.036W/mK and exceeds the minimum thermal resistance path of 0.45m2K/W.
