To ensure your project complies with the building code’s H1 Energy Efficiency clause, our insulation experts can do an H1 calculation free of charge.

Site sign off

Site sign off

You may have the best insulation on the market, but a poor install can significantly reduce its performance. It’s crucial to get it right first time, because once the linings are on you won’t get a chance to go back and fix it. To ensure your project is correctly insulated, our insulation experts can complete a free site sign off. We look for gaps, folds, and tucks, and ensure the right product has been installed in the right place. Once the sign off is complete, we provide a certificate that can be kept on file to give you peace of mind.
