* 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:

Oxfordshire (abbreviated Oxon, from the Latinised form Oxonia) is a county in the South East England region, bordering on Northamptonshire, Buckinghamshire, Berkshire, Wiltshire, Gloucestershire, and Warwickshire.

It is divided into five local government districts: Oxford, Cherwell, Vale of White Horse (after the Uffington White Horse), West Oxfordshire and South Oxfordshire.

The county has a major tourism industry. The area is noted for the concentration of performance motorsport companies and facilities. Oxford University Press has headed a concentration of print and publishing firms; the university is also linked to the concentration of local biotechnology companies.

The main centre of population is the city of Oxford. Other significant settlements are Banbury, Bicester, Kidlington, and Chipping Norton to the north of Oxford; Witney to the west; Thame and Chinnor to the east; and Abingdon, Wantage, Didcot, Wallingford and Henley-on-Thames to the south. Future population growth in the county is hoped to be concentrated around Oxford, Banbury, Bicester, Didcot and Witney, near the South Midlands growth area.

Aluminium  is a silvery white and ductile member of the boron group of chemical elements. It has the logo Al; its atomic number is 13. It is not soluble in water under normal circumstances.

Aluminium is remarkable for its ability to resist rust due to the wonder of passivation and the metal's low density. Structural atributs made from aluminium and its alloys are vital to the aerospace industry and very important in other areas of automation and building. Its reactive nature makes it useful as a catalyst or additive in chemical mixtures, including being used in ammonium nitrate explosives to enhance blast power.

A window is a transparent opening in a wall (or other solid and opaque surface) that allows the passage of light and, if not shut or sealed, air and sound. Windows are usually glazed or covered in some other transparent or translucent material. Windows are held in place by frames, which prevent them from collapsing in.

Insulated glass production, the term "lite" refers to a glass pane, several of which may be used to construct the final window product. For example, a sash unit, consisting of at least one sliding glass component, is typically composed of two lites, while a static window is made of of one lite. The terms "single-light", "double-light" etc refer to the number of these glass panes in a window.

The lites in a window sash are divided horizontally and vertically by narrow strips of wood or metal called muntins. More tough load bearing or structural vertical dividers are called mullions, with the corresponding horizontal dividers referred to as transoms.
