50mm PIR Thermal
The high-performance 50mm PIR insulation board is a general insulating product suitable for various building applications. It’s commonly used when constructing or renovating houses, as well as commercial and industrial complexes. Applied correctly, 50mm PIR boards can help you meet regulatory standards for thermal insulation.
What is 50mm PIR insulation?
Made from polyisocyanurate foam, this PIR insulation sheet is expanded to 50mm and processed into a rectangular board. It has a closed-cell architecture that keeps heat from escaping or entering a room. Only small amounts of water can penetrate the material due to the rigid form of the cells, which is why it works so well as an insulating material.
What are 50mm PIR used for?
50mm polyisocyanurate insulation is suitable for insulating walls, roofs, ceilings, and floors. You can click on any 50mm PIR product to see the manufacturer-recommended applications for that specific PIR insulation model.

Benefits of 50mm PIR insulation
- Reduces heat loss — The closed molecular structure of PIR means heat is not easily transferred through the material. When installed correctly, 50mm PIR insulation sheets will minimise heat losses.
- Improves energy efficiency — Reduced heat loss in your interior spaces means lower energy consumption, which is good for the environment and your pocket. Hello, lower electricity bills!
- Keeps interiors warm and cosy — When your interiors are properly heated, staying indoors is enjoyable.
- Ease of installation — 50mm PIR sheets are light enough for you to install them without breaking too much of a sweat. It’s the kind of product you can comfortably work with even when you have few hands helping.
- Durability — PIR insulation sheets are built to last, and the 50mm PIR insulation is no different. Replacing insulation is a massive project that is time-consuming and expensive. Avoid unnecessary replacement by getting it right the first time when you use appropriate PIR insulation for your building projects.

FAQ
How do I install 50mm PIR insulation?
Each 50mm PIR sheet comes with installation instructions tailored to its recommended applications. Follow each step carefully to ensure the insulation fits properly into each space.
How to cut a 50mm PIR insulation sheet?
The best way to cut 50mm PIR insulation is with a Stanley knife or a sharp saw. It’s essential to ensure the blade is sharp to achieve a clean cut.
How much 50mm PIR insulation do I need?
The amount of 50mm PIR insulation to use is determined by the size of the area to be insulated. A smaller area will require fewer boards than much larger spaces. The number of PIR sheets increases in proportion to the space. To find the exact number of boards to use, measure the area to be insulated, convert it to square metres, and divide this number by the total coverage of one 50mm board.
