The type of window frame and the insulation of its cavity are critical for energy-efficiency and thermal performance (and for strength, durability and maintenance). Aluminum frames are excellent for strength, durability and maintenance but they are a poor choice for thermal insulation. Aluminum is an extremely conductive material.
It is similar to the British aluminium alloy HE9. 6063 is the most common alloy used for aluminium extrusion. It allows complex shapes to be formed with very smooth surfaces fit for anodizing and is popular for visible architectural applications such as window frames, door frames, roofs, and sign frames. [3]
A window is an opening in a wall, door, roof, or vehicle that allows the exchange of light and may also allow the passage of sound and sometimes air.Modern windows are usually glazed or covered in some other transparent or translucent material, a sash set in a frame [1] in the opening; the sash and frame are also referred to as a window.

Note that the term aircraft aluminium or aerospace aluminium usually refers to 7075. [65] [66] 4047 aluminium is a unique alloy used in both the aerospace and automotive applications as a cladding alloy or filler material. As filler, aluminium alloy 4047 strips can be combined to intricate applications to bond two metals. [67]
Cladding can be made of any of a wide range of materials including wood, metal, brick, vinyl, and composite materials that can include aluminium, wood, blends of cement and recycled polystyrene, wheat/rice straw fibres. [2] Rainscreen cladding is a form of weather cladding designed to protect against the elements, but also offers thermal ...
Copper belfry of St. Laurentius church, Bad Neuenahr-Ahrweiler Metals used for architectural purposes include lead, for water pipes, roofing, and windows; tin, formed into tinplate; zinc, copper and aluminium, in a range of applications including roofing and decoration; and iron, which has structural and other uses in the form of cast iron or wrought iron, or made into steel.
Aluminium (or aluminum in North American English) is a chemical element; it has symbol Al and atomic number 13. Aluminium has a density lower than that of other common metals, about one-third that of steel. It has a great affinity towards oxygen, forming a protective layer of oxide on the surface when exposed to air.
In the case of pure aluminium, the grain size has a minor influence on the strength for metals. In the case of alloys, the influence increases with the alloy content. At 5% Mg, materials with grain sizes of 50 μm achieve uniform elongations of around 0.25, at 250 μm they are around 0.28.
