The Manthorpe G912 Joist Seal helps to solve the problem of air leakages that are associated with built in timber joists. This joist seal proposes an alternative to joist hangers, for an easier fit to help speed up the building process.

The box is placed over the end of the joist and built into the inner leaf of the external wall construction. As the timber is drying out and shrinks, the seal is maintained between the masonry and the box, preventing air leakages in the cavity. Located around the inner flange are several push-out pockets for the location of restraining straps as required.
