Save Time, Save Materials, Save Costs


• Totally transparent for easy inspection • Air gap for moisture evaporation • Air tight seal • Simple to fit • Flangeless design for placement •Moisture ingress prevention • Part L and E compliant


Ease of Installation Built-in tolerance lines for ease of placement. The fins on the sides of the cap provide a key for mortar aiding pointing. Perfect placement is further aided by minimum and maximum fill lines which maintain an air gap to allow the wood to dry out. Joist Cap is attached with a nail each side of the cap. It has no flanges or clips to obstruct restraints or blocks. It also has a reinforced over hit zone.


Terraced Housing And Party Walls Designed to fit flush for use back to back in terraced housing or on party walls.


Visual Inspection Translucent material allowing visual inspection for correct load bearing of 90mm on the masonry inner leaf wall.


Air Leakage Because the seal with the masonry is maintained unwanted air leakage between the ceiling void and wall cavity is stopped and thereby heat loss by air infiltration (as required by statutory regulations concerning the conservation of fuel and power regulations).


Sound Transmission Stops air paths around joist ends within separating masonry, stopping noise transference across the cavity wall.


The product is available in two colour coded sizes.
