Types of Insulation Boards

There are 2 types of insulation boards that are commonly used in building projects, which are known as a PIR insulation board and Cavity Wall insulation boards. Both can help to reduce minimise heat loss and reduce energy bills. Alway seek professional advice on before installing an insulation board to see what equipment and other building materials might be needed. If you are looking for thermal and acoustic insulation, then insulation slabs will be a better product.

PIR Insulation Boards

Polyisocyanurate (PIR) insulation board (sometimes referred to as an insulation foam board) is one of the most popular thermal insulation board choices for construction projects. PIR insulation board is made from polyisocyanurate, which is a rigid material and why it makes such a popular choice. An insulation sheet is easy to cut for installation and can be used in a wide variety of applications, such an in a pitched roof, an internal wall, under a loft board - all which better insulate a building, reduce heat transfer and heating bills. We stock PIR insulation foam board from industry-leading brands like EcoTherm, Celotex and Recticel in different types of thicknesses that range from 20mm to 150mm, with the Celotex 100mm thickness being our top seller.

Cavity Wall Insulation Boards

Cavity wall insulation board are designed to fill the space and provide extra insulation between two external walls. They can even be friction fitted between joists and placed on flat surfaces that need to be filled. Cavity boards and slabs trap heat inside your home. An insulation board for cavity walls can have a thermal conductivity value as low as 0.018 W/mK.

There are lots of different types of cavity insulation. You can purchase glass mineral slabs (acoustic insulation), phenolic boards, and PIR boards. PIR is one of the most popular types of insulation for people who want a strong performance cavity insulation board.
