How to cut Kingspan TF70?

1. Mark the cut line clearly – Outline exactly where you need to cut on the TF70 insulation.
2. Pick the right tool – Handsaws, fine-toothed saws, and sharp insulation knives work well for cutting TF70. Use a circular saw for thicker boards, preferably with dust extraction.
3. Score & snap for thin boards – Boards around 20–40 mm thick can be lightly scored on both sides, then snapped along the line.
4. Support the board – Place the panel on a flat surface or a batten so it breaks evenly.
5. Protect yourself – Wear gloves, goggles, and a dust mask. PIR dust may irritate.

How to fix Thermafloor TF70 insulation?

Level the subfloor and make sure it is clean. Lay your Kingspan Therma TF70 panels edge-to-edge so they are flat, with the joints staggered. Use adhesive or mechanical fixings where needed on screeded or timber floors. Finish with your selected floor covering once the screed or deck layer has been installed.

Note: Fixings are only required if specified in the floor system design.
