Benefits for house builders

bulletBuilding regulation compliance:
bulletCAPIT joist seals effectively assist in meeting the requirements of Parts E and L of the Building Regulations. They provide a better seal against air leakage than any other proprietary joist seal and better than flexible sealant. Click here for more information.

Health and safety:
bulletCAPIT joist seals are used with joist ends built into the wall and avoid the risk of joist-hanger collapse.
bulletUnlike other joist seals, once the joists have been laid and battened, with CAPIT joist seals there is no need to lift the end of the joist in order to fit the seal.
bulletUnlike some other joist seals, CAPIT joist seals do not have large exposed flanges and tabs that cause a tripping hazard until the wall has been built around them.

Inexpensive:
bulletCAPIT joist seals are competitively priced.
bulletThey avoid the costs of joist hangers, mastic and underslinging the floor.

bullet

Quick and easy:
bulletThe CAPIT joist seal simply fits over the end of the joist in a matter of a second or two once it has been laid - no need to lift the joist.
bulletThe CAPIT joist seal grips the end of the joist, while the wall is being built - no need for nails to hold it..
bulletThe wall is built around the capped joist end in the conventional way.
bulletNo need to wait for mortar to harden.
bulletNo exposed flanges to interfere with flooring or plasterwork.
bulletColour-coded for easy identification on site.

bullet

Strong:
bulletThe joist ends are supported directly on the wall.
bulletNo exposed flanges and tabs to impede proper tooling-in of the mortar all around the joist, front and back.

bullet

Compact:
bulletBecause of their design, CAPIT joist seals can be interleaved in their packaging, and they are devoid of large flanges and tabs to interfere with tight packing. It is estimated that a box of CAPIT joist seals occupies as little as about 15% of the volume of a box of the same number of flanged, closed-bottomed, joist seals. Less space taken up on site.
