This joist seal from Manthorpe's G912 range has been created to resolve the issues of air leakage, related to built-in timber joists. With the box positioned over the end of the joist, this joist seal can be built into the inner leaf block work of the external wall construction to form an air-tight seal with the masonry and ensure excellent insulation.

As the timber dries out, it shrinks within the joist seal as the seal is still retained between the masonry and the box, inhibiting air leakage into the cavity, and conforming to Part L of building regulations. Situated around the inner flange are several push-out pockets to position the restraining straps as needed. Effectively mounting the joist in the wall removes the requirement for awkward joist hangers.
