70mm PIR Thin-R
70mm PIR insulation combines the thermal efficacy of polyisocyanurate (PIR) with a slim build to provide a seamless insulation solution for all types of construction spaces. Commonly sold in the shape of panels or boards, 70mm PIR sheets offer a high amount of thermal resistance, making them a go-to solution for many general insulation applications.
What is 70mm PIR insulation?
Made using polyisocyanurate, PIR insulation 70mm is a type of plastic foam produced when isocyanates, polyols, catalysts, blowing agents, and other additives are combined. The foam is inserted between two foil facings, and a blowing agent is applied to increase its size. At 70mm, the process is stopped, and the product is further cured to produce the sheets we see in use today.
What are 70mm PIR used for?
You can apply 70mm PIR sheets to many of your room insulation needs. The boards are intended for insulating floors, flat roofs, pitched roofs, masonry walls, steel and metal-framed walls, and partition walls. They may also be used on external walls, depending on what you want your insulation efforts to achieve. For example, suppose you aim to meet building standards by achieving a specific outcome. In that case, you may need to layer your 70mm PIR insulation board with additional PIR boards to boost thermal resistance.

Benefits of 70mm PIR insulation
- Easy handling — 70mm PIR boards are lightweight, making them easy to carry and move from one place to another, and fit into the space you’re insulating.
- Moisture resistance — PIR has a low water absorption rate. Similarly, the backing material, which is usually aluminium foil, also acts as a barrier against water penetration, boosting the board’s moisture resistance.
- Low toxicity — Since few toxic compounds are used in their manufacture, PIR insulation boards have low toxicity. They also produce minimal waste when cut, and are among the materials considered reasonably safe.
- Durability — When installed correctly, 70mm PIR insulation can serve you for 50 years or more. It’s designed to stay in place for the lifetime of the building, unless the building is severely damaged, in which case you’ll need to renovate and replace the insulation.

FAQ
How do I cut 70mm PIR insulation?
Divide your 70mm PIR board into pieces quickly and easily using a Stanley knife or saw. Though rigid, PIR insulation is soft enough for a knife or saw to slice through.
How do I install 70mm PIR insulation?
Follow the manufacturer’s installation instructions for the specific application, whether that’s between joists or above, between or below rafters. Also included are guidelines for securing the insulation board.
How much 70mm PIR insulation do I need?
Measure the area you want to insulate. Divide this by the total coverage of a single 70mm PIR sheet. Keep in mind that PIR boards are available in various lengths and widths. If you choose a smaller board size, you’ll need more pieces than if you opt for a larger board.
