Manufactured to resolve the difficulties associated with built-in timber joists, of air leakage, this joist seal, from Manthorpe's G912 range, can be placed over the joist end and fitted into the inner leaf block work of the external wall construction to ensure great insulation and to create an air-tight seal with the masonry.

Once the timber has dried out and shrunk within the joist seal, the seal is uncompromised between the masonry and the box, therefore stopping air leakage into the cavity and adhering to Part L of building regulations. Positioned around the inner flange are multiple push-out pockets to place the restraining straps as necessary. Successfully installing the joist in the wall eliminates the need for awkward joist hangers.
