TOPIC 8 : WINDOWA window must be aesthetically acceptable in the context of building design and surrounding environment.
-
to provide for occasional rapid ventilation and sunlight entry.to provide a vision out with the world outside the buildingwindow should be selected or designed to resist wind loadings, be easy to clean and provide for safety and security.

WINDOW MATERIALS
Windows are made from wood, aluminum, PVC, fiberglass, or from a combination of these materials.
i. WOOD WINDOWSWood windows are warm, traditional and aesthetically pleasing. Because it is a good insulator, wood does not become cold like metal and glass. Wood is treated with preservatives to prevent rotting. Wood windows can be painted on the exterior, or clad with aluminum or PVC profiles for better weathering and reduced maintenance.
-
ii. ALUMINUM WINDOWS
Aluminum windows are more durable than wood, and are thinner, lighter, and easier to handle.But aluminum is a poor insulator and in cold weather, Most recent aluminum windows are manufactured with a thermal break, a vinyl or rubber strip that separates the exterior and interior aluminum parts of the window. The thermal break reduces the movement of cold from the outside to the inside of the building. Most commercial applications still specify aluminum windows.
-
iii. PVC WINDOWS
PVC windows are relatively new, having only been introduced during the last 25 years. These windows are extruded from highimpact resistant polyvinyl chloride (PVC). PVC windows have excellent weathering characteristics, are almost maintenance-free and have excellent resistance to heat loss. PVC is available in several extruded colours.
-
iv. FIBERGLASS WINDOWS
Fiberglass windows are the latest window products to be developed. Fiberglass and PVC lineals look similar at first glance, however, fiberglass is much more rigid than PVC
