* Vinyl and fiberglass frames have not been around for long enough to assess their long-term durability. Because vinyl is not as strong as other frames, some vinyl frames are reinforced with metal; however, this will reduce the thermal efficiency of a vinyl window frame.

** Modern metal window frames typically consist of two surfaces separated by a thermal break made of an insulating spacer material. While this can double thermal resistance, it is still less than half that of other frames.

*** Metal window frames durability depends on the geographic location, for example, in coastal areas the effect of saltpetre (Potassium nitrate) will quickly damage aluminium.

Windows can be a significant source of heat transfer. Insulated glazing units therefore consist of two or more panes to reduce the heat transfer.

Frames and sashes can be made of the following materials:

Milton Keynes (pronounced /ˌmɪltən ˈkiːnz/ , often abbreviated MK, is a large town in Buckinghamshire, England, about 60 miles (97 km) north-west of London. It is also the principal town of the Borough of Milton Keynes. It was formally designated as a new town on 23 January 1967. Its 89 km2 (34 sq mi) area incorporated the existing towns of Bletchley, Wolverton and Stony Stratford along with another fifteen villages and farmland in between. It took its name from the existing village of Milton Keynes, a few miles east of the planned city centre. Uniquely for the United Kingdom, the urban form uses a 1 km grid for the top level of street hierarchy: the local form of most districts is more traditional. At the 2001 census the population of the Milton Keynes urban area, including the adjacent town of Newport Pagnell, was 184,506, and that of the wider Borough, which has been a unitary authority independent of Buckinghamshire County Council since 1997, was 207,063 (compared with a population of around 53,000 for the same area in 1961)

Aluminium is the most widely used non-ferrous metal. Global production of aluminium in 2005 was 31.9 million tonnes. It exceeded that of any other metal except iron (837.5 million tonnes).[31] Relatively pure aluminium is encountered only when corrosion resistance and/or workability is more important than strength or hardness. A thin layer of aluminium can be deposited onto a flat surface by physical vapor deposition or (very infrequently) chemical vapor deposition or other chemical means to form optical coatings and mirrors. When so deposited, a fresh, pure aluminium film serves as a good reflector (approximately 92%) of visible light and an excellent reflector (as much as 98%) of medium and far infrared.
