Wood/Clad Windows

Wood offers good thermal performance and natural beauty. Montana Window & Door offer products in a wide variety of interior wood species.  All of Montana Window & door’s wood products have EXTRUDED aluminum cladding on the exterior to minimize Maintenance and Damage from Hailstorms. Montana Window & Door offers products incorporating “engineered” wood components, in non-visible areas, to enhance performance and achieve optimal wood utilization.

Vinyl Windows

Vinyl is the most commonly used framing material, because it offers good thermal performance and requires little maintenance. It can be used to produced very cost-effective products, but vinyl windows can also be provided in a choice of interior finishes, including woodgrains and colors. All of Montana Window & Door’s vinyl products incorporate rigid vinyl with multi-chamber profiles for strength and insulation. The Frame and sash corners in these vinyl windows are Fusion-welded, creating a joint that is more resistant to air and water infiltration than corners that are mechanically fastened with screws.
