How Thick is the DIY InsulationUpdated 4 days ago

The overall thickness of the DIY Insulation Kit varies due to the material being spongy.

The main features of the insulation include:

• Up to 78% reduction in heat loss
• Compact insulation wadding keeps the weight low but the performance high
• Foil laminated on both sides, to ensure heat is reflected back into the garage in the winter, and heat is reflected away from the garage in the summer
• Easy DIY installation, requiring no specialist installer or tools

The U-value with the garage door insulation attached using 2mm thick spacers is 1.28 W/m²K. This represents a 78% reduction in heat loss through the door.
