Is uPVC a good thermal insulator?

Yes, UPVC is a an excellent insulator. Unlike aluminium which is a conductor, uPVC is an insulating material and when combined with an IGU (insulated glazed unit) it is the perfect choice for maximum efficiency. Its coefficient of heat conductivity is actually slightly lower than wood at 0.17 W/mC°, compared with 0.23 W/mC°. The equivalent coefficient for aluminium is approximately 210 W/mC°. As 40% of household energy can be lost through windows huge savings can be made. A degree of comfort in the living space is achieved that cannot be equaled with single glazed aluminium windows.

I sourced the windows for my passive solar designed house from Elite Double Glazing. I chose double glazed UPVC windows for the thermal performance and low maintenance characteristics they offer. I am happy to recommend the company and the product.  In all my dealings throughout the process of buying, transporting and installing the windows, the prompt responses and reasonable pricing were a significant part of my decision to deal with the company.
