Aluminum Clad Windows
Aluminum clad wood frame replacement windows are wooden windows whose frames are covered on the exterior with an aluminum cladding. These windows provide a higher U-value insulation along with the preferred traditional look that many homeowners prefer. Many architectural designs include aluminum clad windows because these replacement window alternatives display the attractive wood frames on the interior of the home along with the weather-resistant exterior cladding which protects the outside of the window. This allows the homeowner to take advantage of the higher insulating U-value of a clad window while enjoying the traditional look of the interior wood frame.
Replacement aluminum clad wood windows are an increasingly popular window choice for many homeowners due to a variety of reasons.
 Energy Efficiency
Aluminum clad replacement wood frames have the advantage of wood’s natural insulating qualities but they don't require the type of annual maintenance that a non-clad wood window demands. Wood frames may warp or rot when exposed to the elements but the addition of an aluminum cladding allows the window frame to resist the weather conditions. This provides for a strong, sturdy and maintenance-free window frame.
Aluminum clad window frames do not require additional maintenance after the initial installation. They are durable and can last for decades.
Wood frame replacement windows with aluminum cladding are sturdy windows. The frames can support multi-pane windows including double and triple panes.
Installation of an aluminum clad replacement window is a straight forward job and can be accomplished by a carpenter or general window installer. Installation requires new flashing, sealants, insulation and caulking though replacement of an aluminum clad window sash can be accomplished with just a sash replacement kit. Most major aluminum clad window manufacturers train and certify their own installers, making it easy to find a contractor who is able to both sell and install the replacement windows.
Most major aluminum clad window manufacturers offer a 10 years warranty on the window's sash and frame. These warranties are transferable from owner to owner.
Homeowners should investigate the ins and outs of wood clad frames before purchasing aluminum clad replacement windows for their home.
Wood window frames insulate well but they also contract and expand according to weather conditions. Properly applied aluminum cladding may prevent this situation but if the aluminum cladding is not applied properly to the wood frame the window may leak and the frame can rot or warp. Homeowners are advised to always purchase aluminum clad replacement windows from a reputable manufacturer.
 Design & Color

 Frame Size
