WITH development in modern architectural designs, the use of aluminum window frames has become a popular choice for framing windows in homes from the 1960s through the mid-1980s. However, since the introduction of polyvinyl chloride (PVC) window in the country, the use aluminum frames may have dropped steadily, but the product remains homebuilders choice.According to industry stakeholders, several reasons for the popularity of PVC frames may not be far-fetched from reasons ranging from cost durability to maintenance, but there are also reasons to consider aluminum-framed windows in the home.For NIGELEX, a major manufacturer of aluminum products, aluminum is a relatively inexpensive metal, its strong and durable and easily shaped into any length to frame windows.Aluminum conducts heat from the home and dissipates it to colder surroundings. It is possible to buy aluminum frames that have been fitted with a less conductive material between the panes of windows to prevent heat loss.However, Austin Laz, a popular PVC distributor, in a chat with The Guardian revealed that one major factor for the popularity of PVC windows, is that PVC comes in varying qualities, and some of the best quality PVC is in line with the cost of aluminum.Another reason that PVC frames are popular is because they are excellent insulators. PVC window frames are also called vinyl frames, because they are made from rigid, impact-resistant PVC. They have hollow spaces inside the frames that make them resistant to heat loss and condensation.On maintenance, property experts at eHow.com are of the opinion that, both aluminum and PVC window frames are easily cleaned with a damp cloth, as both are also durable, although inexpensive. PVC window frames tend to expand and contract when exposed to extremes of heat and cold, making them harder to operate and prone to air leakage. Vinyl window frames cannot be painted and darker shades may fade over time.PVC is not as strong as aluminum, and because of the tight fit possible with aluminum-framed double glazed windows, they are favoured for security. Its difficult to pop out a window from an aluminum frame if it has been properly installed.Some of the more expensive PVC frames are reinforced with metal to make them more secure. A professional Aluminum windows never need painting, dont rot or warp and are rigid and strong enough to bear the load of window lintels with minimal reinforcement. Over time, however, aluminum can deteriorate in coastal areas with salty air.The main advantage is that aluminum components do not rust as easily as iron. Aluminum fences are given a powder-coat finish that protects the surfaces. This kind of a finish also enhances its appearance and provides a smooth surface for painting, if desired. All the components of the fence are drilled and powder-coated prior to assembly. Extreme care is taken during assembly by using sturdy fasteners, brackets, and rivets. Wherever these fasteners, etc., need to be visible, attractive stainless steel ones are used. This provides both looks and strength.As aluminum is an easy metal to work with, a plethora of style choices and adornment options are made available to clients. The flexibility of the metal allows for several designs that can complement the facade of the structure they are installed around.
