Painted Finishes:

Alpen’s sturdy fiberglass frames are made with thermoset resins that do not soften or melt when heated.  This means Alpen windows can be painted with dark colors like black and dark brown, and used in even hot, sunny, high altitude climates without warping or sagging.

Alpen sliding glass doors are available in virtually unlimited color options, ranging from 14 standard colors to any custom color or split finish/two tone styles.

 

Alpen offers the widest range of insulated glass options available, providing unlimited glass design and performance freedom.  We draw from over  216,000 combinations of glass, low-e, gas and film to custom-engineer insulated units to meet any performance target and any aesthetic style using glass with tints, colors, obscure patterns, spandrel ceramic frit, and more.

Triple and Quad-Pane Glazing:

Alpen IG Cross Sections FilmAt the core of our technology is use of advanced suspended coated film glazing technology.  Internally mounted low-e films complement the benefits of low-e glass. Combining both film-based coatings and glass-based coatings creates a lightweight, multi-cavity insulating glass unit that reflects heat and harmful UV radiation while maximizing light transmission. It provides superior insulation performance.
