Joist seals in a wide range of sizes and permutations

Joist seals in a wide range of sizes and permutations

Joist seals – another innovative product from Manthorpe designed in response to the evolving building regulations. Our joist seals are designed to meet the requirements of Part L of the Building Regulations relating to insulation and air leakage. The joist seal is placed on the end of the joist, is built into the external wall and remains sealed thanks to the foam gasket seal, which maintains the seal over time in the event of any joist shrinkage; a simple and elegant solution.

The two size ranges (G912 and G913) cover a multitude of joist cross-section dimensions. Overall, the joist seals cater for joist widths ranging 38-180mm, joist heights up to 302mm and blockwork depths from 100mm to 140mm. In the case of smaller joists, packer materials can be used. Further information is in the downloadable information sheets.

In order to ensure the correct joist seals are ordered, the product code is composed of the three relevant dimensions: maximum joist height, joist width and blockwork depth. This also makes on-site final checking and subsequent re-ordering both simple jobs.

 

Joist seals – meeting the requirements of Part L of the Building Regulations

To comply with building regulations, restraining straps should be fitted at 2m centres. Each joist seal is supplied with cut-out slots, which are easily removed to allow the affixing of these straps.

Our joist seals are entirely British manufactured, as are the majority of our products; proudly supporting British manufacturing and minimising risk in the supply chain and in your project schedules.
