Aluminum Window Frame
Light, robust, tough, noncorrosive, and simply extruded into the complicated shapes needed for window components, aluminum can be fabricated to particularly close tolerances to produce specific forms for the insertion of glazing, weatherstripping, and thermal breaks. Over time, the steel or zinc fasteners utilised for aluminum windows may react with the aluminum and corrode. I simply went to my regional hardware supply business and purchased exterior metal paint. Vinyl frames are thicker than their aluminum counterparts, which may well not be as appealing, based on the building’s style. If a painted aluminum frame is chipped or scratched, the metal will show via.
From a thermal point of view, wood-framed windows execute effectively, with frame U-aspects in the range of .3 to .5 Btu/hr-sq ft-°F. The biggest disadvantage of aluminum as a window frame material is its high thermal conductance, which raises the all round U-element of a window unit. You … Read the rest
