What Thickness Do I Need?
When choosing an insulation product it is important to select the right thickness for the job. You need to consider the space you are insulating and the climate. The thicker the insulation, the better the overall U Value will be, meaning that less heat that can escape the area or property.
Always measure the space you want to insulate before you purchase your insulation, to ensure that the thickness you buy will fit in the space.
The GA4000, TB4000, and XR4000 thermal insulation products have been designed to meet or exceed the latest European standards and are the most commonly used boards for internal floor, wall, and roof applications.
Similar to internal projects, if you are insulating a cavity wall, you will also need to take into account the width of the cavity. When it comes to installing cavity wall insulation, always consult a professional.
