Timber has always been the traditional material of choice for doors and windows in homes. Wood gives a solidity and permanence to interiors that does not come as easily from other more modern materials like steel, aluminum or PVC.
Wooden windows however, do require a lot of maintenance and protection from weather. Alu clad windows offer a combination of aluminum and timber that satisfies the traditional look of windows on the inside, while allowing the sturdier and more weather resistant aluminum to act as a frame on the outside that is normally exposed to the elements. This combination reduces the need for exterior maintenance.
Aluminum profiles that are used for frames of alu clad windows are anodized or powder coated and this greatly increases their ability to resist weathering. These clad frames will not require any maintenance, except for cleaning. The interior of these windows will have attractive wooden finishes that can be designed or finished to complement the interiors.
It is important that any timber being used in alu clad windows be seasoned and well treated, so that it competes in durability with the aluminum of the outside frame. The outside frames will require almost no maintenance, while the wooden interior may need to be painted or polished every five or six years. These windows are better insulators than windows made entirely of aluminum, as wood has high thermal resistance.
Alu clad windows have a smooth finish and give a rich and clean look that makes an impact on the exterior of a home. Homes with these windows will stand out in a neighborhood. These windows have a greater resistance to impact and abrasion and will give many seasons of service. The wooden portion of the interiors of these windows give the warm look that is highly preferred by many homeowners. They can be of great advantage to people staying in waterfront properties or in places that have a high humidity.
The combination of wood and aluminum offers a great variety in finishes and colors that give a lot of scope to interior designers. Manufacturers also offer guarantees for such windows and this makes windows that offer their customers a greater peace of mind.To make these windows a wooden sash and frame is covered on the outer side with an extruded aluminum section. The section is made in such a way that it slides on the wood, but even then is secured independently to the external walls.
The structural stability of these windows is ensured by having all its components being able to be pressure fitted to each other and then further secured by screws. The wooden frames have the usual mortise and tenon joints to complete the sashes and wooden frames. It is also customary to use vinyl liners between the timber and metal to prevent water accumulation or moisture crossing over from the outside.
Alu clad windows have outstanding technical and performance properties that also allow for a lot of flexibility in design. They are recommended by many architects and builders for homes that they are required to design or build.
