Installation Instructions for K8 Cavity Insulation
To proceed with the installation of Kingspan K8 Cavity Board and meet the requirements you’ve mentioned, follow these steps:
- Prepare the inner leaf:
- Ensure the inner leaf is constructed to an appropriate level.
- Make sure the surface is clean and free of any debris.
- Remove excess mortar:
- Inspect the exposed edges of any installed insulation boards.
- Remove any excess mortar or mortar droppings from these edges.
- Clean the surface thoroughly to create a smooth and even base.
- Offer the K8 Cavity Board to the external face of the internal leaf:
- Take the Kingspan K8 Cavity Board and align it with the external face of the inner leaf.
- Ensure the board fits properly and covers the desired area.
- Hold the board in place temporarily.
- Secure the K8 Cavity Board in place:
- Install wall ties along the edges of the insulation board.
- Use wall ties that include a retaining disc or clip.
- Make sure the wall ties are of the double drip type, with the drip facing downward.
- Attach the retaining disc or clip securely to the wall ties.
- This will hold the insulation board in position.
- Build up the outer leaf:
- Proceed with constructing the outer leaf.
- Continue building it up to the level of the top of the installed insulation boards.
- Ensure that the outer leaf is properly aligned and built according to the desired specifications.
- Repeat the process:
- Once the outer leaf reaches the desired level, repeat the steps mentioned above.
- Offer the K8 Cavity Board to the external face of the outer leaf.
- Secure it in place using wall ties and retaining discs/clips, just like before.
- Maintain a residual cavity:
- Throughout the construction process, ensure that a residual cavity of at least 40 mm is maintained.
- This is in accordance with the moisture penetration provisions set out in the masonry structures standard AS 3700, as called up in the NCC Volume 1, Section B1.4.
- The residual cavity helps with moisture control and insulation performance.
By following these steps and adhering to the guidelines provided, you can proceed with the installation of Kingspan K8 Cavity Board while maintaining the required standards for construction.
Cutting and Packaging
To cut the boards, you have two options:
- Use a fine-toothed saw.
- Score the board with a sharp knife, snap it over a straight edge, and then cut the facing on the opposite side. Ensure precise trimming to achieve closely fitting joints and maintain insulation continuity.
The boards are packaged in packs, labeled, and shrink-wrapped in polythene, based on the quantity required.
Handling and Storage
The packaging of Kingspan Kooltherm should not be deemed suitable for providing long-term outdoor protection. It is highly recommended to store the boards indoors within a building whenever possible. In cases where outdoor storage is unavoidable, it is important to stack the boards above ground level and shield them with an opaque polythene sheet or a weatherproof tarpaulin. Boards that have come into contact with moisture should be avoided and not utilized.
