Manthorpe’s G913 gives unrivalled protection against air leakage, saves time on building sites and means there’s no need for awkward joist hangers during installation. Simply push the joist onto the end section of each joist and then build it into the blockwork. Fully compliant with Building Regulations Part L, Manthorpe's joist seal is developed with several push-out pockets located around the inner flange, meaning restraining straps can be added in if necessary.

When the timber in question dries out and naturally starts to shrink, the seal created by Manthorpe's G913 joist seal will retain its integrity, meaning no air leakage into the cavity. Each product has been one-hour fire tested in party wall details.
