The thickness of your ceiling insulation should be chosen based on the specific requirements of your building and the level of thermal efficiency you aim to achieve. Generally, a thicker insulation offers better thermal resistance. In the UK, a common guideline is to aim for an insulation thickness that achieves a U-value (a measure of heat loss) in line with current building regulations.

For instance, our polypad ceiling insulation comes in various thicknesses, ranging from 100mm to 200mm. The choice depends on your specific needs and the space available for insulation. If you’re unsure about the appropriate thickness for your project, do feel free to contact us for help.
