Technical Information - Benefits Of Alumaflex Multifoil Insulation
At Nu-Look Conservatory roof solutions we have been replacing polycarbonate and glass conservatory roofs with light weight solid insulated roofs for over 5 years, so how do we do it?
Firstly, we completely remove your old conservatory roof and build you a bespoke braced timber roof, this is built on site to ensure that the measurements are exact, as no two conservatories are the same, We install 3 layers of insulation, Alumaflex multifoil insulation is installed between the membrane and the timber rafters, we then fit 40mm insulation boards between the rafters, this is then covered with 27mm insulated plasterboard, which is then skimmed to provide a smooth perfect finish, giving a uValue of 0.18.
As replacing your conservatory roof with a solid insulated roof falls under Building Regulations, please click here for more details, we provide a Building Regs Certificate will all installations and a 10 year insurance backed guarantee.
Below, you can see exactly how the insulated solid conservatory roof is constructed.
