Is an Insulation Board Right For My Home?

An insulation board is an all-rounder product that can be delivered in any part of a building or property, including walls, floors and roofs.

It does not matter what type of home you have, as insulation boards are flexible in their application. These products are ideal for those wanting to save money from their heating bills every year.

Boards for Flat Roofs

Flat roofs primarily use insulation boards. Since these boards have strong features that can withstand foot traffic, they are an important asset to consider when creating modern roofs with single-ply construction.

Due to the many regulations, UK Flat Roofing will always recommend that you hire a professional when insulating a flat roof.


PIR insulation is the most used and efficient insulation material found online and is available as easy to cut boards. PIR can be used in many systems and installed in a variety of ways.

UK Flat Roofing provides materials that are efficient for insulating all properties and systems, see our range above.

Insulation board thickness can vary depending on where you want it applied in your home. Popular insulation board thickness comes in 25mm, 50mm, 75mm, 100mm and 150mm, which are all available at UK Flat Roofing.

The insulation thickness will depend on the U-Value you require to achieve within the regulations.

Please ask either an Architect or Insulation Specialist such as ourselves if you are unsure what you need.

Insulation boards are more expensive than rolls but compensate with better thermal values at half of their thickness, as well as easier installation..
