Multi-purpose 100mm insulation boards
Kingspan TF70 100mm PIR insulation is a high performance rigid thermoset insulation which can also be used for lots of other applications such a lining walls in between battens and insulating floors; both timber and concrete. 100mm Thermafloor TF70 is the sister product of Kingspan TP10 and Kingspan TW55 - same specification just referred to with different names for use in different applications.
How can I cut PIR insulation?
Cutting 100mm TF70 Kingspan is a fairly simple task. You can use a regular handsaw to achieve the perfect fit, even in tricky areas. Remember to fill any gaps with expanding urethane sealant to prevent drafts and cold spots. For thinner boards (around 50mm or less), a sharp knife will create a cleaner cut with less mess. Due to potential dust, wearing safety gear, especially a dust mask, is highly recommended!
The technical stuff!
Amongst building insulation options today, PIR (polyisocyanurate) stands out for its exceptional thermal efficiency.
PIR starts as a liquid mixture of polyols and isocyanates. As these chemicals react, they create a wet foam that hardens and locks into its final shape. This precise process allows manufacturers to create insulation sheets with consistent thickness and minimal variation.
Is PIR Insulation waterproof?
The answer is no. PIR insulation is constructed from closed-cell foam, a material with tiny gas-filled cells. These cells offer excellent insulation but aren't entirely watertight. To improve moisture resistance, PIR boards are encased in foil. If the foil becomes wet during transportation, it's crucial to allow the boards to dry naturally indoors before installing them.
