115mm PIR
PIR insulation 115mm bears the typical rigid structure of PIR, one of the most popular insulation materials in the construction industry.
What is 115mm PIR insulation?
115mm PIR insulation is a 115mm thick polyisocyanurate (PIR) panel designed to improve thermal control in buildings. The board has all the characteristics that make PIR an outstanding insulation material. These include exceptional thermal insulation properties, low vapour permeability (however, not vapour proof), dimensional stability, and durability.
What are 115mm PIR used for?
115mm PIR board sheets are well-suited to many general insulation applications, including roofing insulation, wall insulation, flooring insulation, and loft insulation. Check the manufacturer’s recommended areas of application, as some may be optimised for specific uses, for example, partial or full fill cavity wall insulation.
Types of 115mm PIR
We feature 115mm polyisocyanurate insulation from different brands.
Some manufacturers, like Ecotherm, produce 115mm PIR panels with tongue-and-groove edges. Such edges have slots that ensure the boards interlock to fit tightly against each other, minimising air gaps when you install the panels in layers.
The boards come in various sizes, with 2400mm x 1200mm and 1200mm x 450mm being among the most popular.
Benefits of 115mm PIR insulation
- Superior thermal resistance — When PIR insulation is installed correctly, heat transfer through the boards is low. This allows the heat generated within a building to stay inside, keeping the space comfortable.
- Maintains its performance over time — Your 115mm PIR insulation board will maintain its rigidity over time, guaranteeing sustained performance and durability.
- Trouble-free installation — The installation of PIR insulation boards is a straightforward process, made even easier by the lightweight nature of the panels.

FAQ
How to install 115mm PIR insulation?
The installation process may vary depending on where you’re installing your 115mm PIR boards. Consult your user guide for the specific steps to follow for each application. In general, however, you’ll go through these main actions:
1. Prep the area by cleaning it.
2. Measure the area and do the same on the PIR board to ensure you have the correct size of board.
3. Cut and position the board against the wall or other space you’re insulating.
4. Ensure all boards are tightly fit together.
5. Secure the panels.
How to cut 115mm PIR insulation?
Begin by marking the location where you will cut. Place the board on a flat surface to keep it from shaking when cutting. This will also ensure you get a neat cut. You may need to make additional markings next to the first mark you made and along or across the board so that you end up with a straight cut. Then use an insulation saw to cut the panel.
How much 115mm PIR insulation do I need?
Calculate the total area that requires insulation. Divide this by the total coverage of one 115mm PIR sheet. This will help you know how many PIR panels to buy.
