Aluminium Windows Profiles


The bottom line here is that modern aluminium profiles are absolutely no worse insulated than wooden or, even more so, plastic ones. On the contrary, modern aluminium window profiles are distinguished by the best thermal performance and are often used in the construction of passive houses. As a result, the price of aluminium windows and doors has risen considerably in recent years, and we currently have to pay more for them than for wooden windows!
