40mm Insulation

40mm insulation is a thick insulation that's robust and effective for enhancing thermal efficiency and reducing energy consumption. The increased thickness offers superior performance in maintaining indoor temperatures. 40mm insulation also provides better energy savings compared to thinner options. 

Its versatility and effectiveness make it a preferred choice for many building projects. If an application requires higher levels of thermal resistance, 40mm insulation is particularly beneficial for this. It contributes to a more energy-efficient and comfortable living or working environment. Whether you're applying it to ceilings, floors, roofs, or walls, 40mm insulation is suitable where space may be limited. 

The exceptional thermal conductivity of 40mm insulation serves as a supporting insulative benefit in cold and warm temperatures. What's more, 40mm thick insulation is made from a vast range of materials, not limited to foilmineral woolwood fibre and PIR, to suit different needs for the building. 

In addition to thermal benefits, some 40mm insulation solutions have acoustic insulative properties and fire protection for further support. Couple that with the different dimensions available, and you have lots to choose from to suit specific project requirements

At Insulation Superstore, you can discover 40mm insulation solutions from leading brands like JCW Acoustics, YBS Insulation, Kingspan, and more.
