Extruded aluminum has proven over time to be the best material for long lasting, low maintenance commercial windows. Marlin Windows uses high quality aluminum alloys best suited for window applications. All Marlin windows use extruded exterior glass stops to allow matching anodized finishes and provide extra strength under negative window loads.
Marlin thermally improved extrusions are accomplished by placing a specially designed cavity in the extrusion that is filled with a high density polyurethane. The bottom side of the cavity is then debridged with a saw, resulting in two separate extrusions that are held together by the polyurethane "thermal barrier". This provides a higher resistance to heat loss and condensation.
Marlin offers both anodized and painted finishes in any available specification or color. Because custom colored windows require extended lead times for color selection, sample submittal, and production as well as additional cost for setup and minimum order quantities, Marlin recommends this as an option for larger projects that allow for added time.
For fast track and smaller jobs, Marlin inventories the two most popular anodized finishes - dark bronze and clear anodized. In addition Marlin's commercial line windows are also available in a white painted finish, since these products are often used as a residential upgrade.
