Forming the base of our clad windows, it adds beauty to interiors, provides great insulation, and is extremely durable. Wood fiber reclaimed from our manufacturing process is also a key ingredient in our patented Fibrex composite material.

• Natural interior beauty

• Excellent insulation

• Ideal for traditional homes

Fibrex® Composite

Used to make our 100 Series windows inside and out, it’s twice as strong as vinyl and made by fusing reclaimed wood fiber and thermoplastic polymer. This innovative material performs well in extreme temperatures and is virtually maintenance free. It’s also used as a supporting material in various other product lines.

• Made from reclaimed wood fiber + polymer

• Stronger than vinyl

• Low maintenance

• Used in 100 Series & Renewal lines

Aluminum

As the protective material (cladding) used on the exterior of E-Series windows, it resists the elements, is virtually maintenance free, and can be customized to various shapes through our extruding process.

• Durable and weather-resistant

• Customizable finish options

Fiberglass

Together with Fibrex composite material, this glass-reinforced resin is used on the exterior of our A-Series windows because it’s tough, weather resistant, and maintenance free. It’s part of what makes A-Series windows so high performing and a great choice in areas with extreme weather like hurricanes.

• Strong and stable

• Excellent in extreme climates
