Manthorpe’s G912 joist seal saves time, eliminates the need for impractical joist hangers and gives unrivalled protection against air leakage. Simply place the box at the tip of a joist, then install at the inner leaf. The joist seal fits into the interior layer of the wall via foam gasket that is not adversely affected once the timber dries and shrinks. The seal at the masonry and box remains durable and prevents air leakage into the cavity.

The inner flange of the box comes with push-out pockets that allow restraining straps to be used where required. Each item is one-hour fire tested in party wall details, and fully compliant with Part L of Building Regulations.
