Insulation Boards & Sheets
Insulation boards are rigid pieces of wood, plastic or aluminium used for thermal resistance in walls, roofs, and floors. They can be used to create a continuous insulating layer that helps maintain indoor temperatures. Insulation board’s thermal performance can be enhanced with add-ons like foil facing and mineral glass coating, improving their U-value. They can even reduce noise pollution in residential homes and commercial buildings.
Also known as roof insulation boards or insulation panels, popular types of insulation board include PIR (polyisocyanurate), XPS, EPS, wood fibre and aluminium. Many of these are types of rigid foam insulation board, which is known for its high compressive strength and moisture resistance. Insulation board materials are also easy to handle and can be cut to fit specific dimensions.
Why choose insulation board?
When comparing the different types of insulation on the market, it is important to know what makes board insulation unique and if it could be the best fit for your project or application. Generally speaking, insulation boards have a higher R-Value than other materials such as mineral or glass wool. To put this simply, it means you get more insulation in a thinner profile – Ideal for spaces where there isn’t room for bulky layers.
If you’re opting for PIR board with foil facing pr XPS insulation, you’re benefitting from their high resistance to moisture, which other types of insulation don’t have. This means they can be used in areas that are likely to get damp or wet, such as flat roofs, basements, and external walls.
These rigid boards act as a type of thermal insulation sheet, and are simple to measure, cut, and install. They can form part of the overall structure of a wall without any sagging over time, which can be a risk with less solid insulation such as fibreglass batts or mineral wool.
