Alpen HPP X25 series combines a fully-insulated framing systems with spectrally selective glass packages to achieve high insulation performance across the full-frame — not just measured at center of glass. Inert gas fill, with a choice of argon or krypton Suspended film reduces convection and energy transfer without the weight and size of a third
More than 35 companies worldwide now manufacture commercial, institutional and residential “multi-chamber” IG units based on a performance array of crystal-clear, low-emissivity films suspended midway between two panes of glass. Adhesion and Sealant Reliability Film Adhesion Verification – Testing extending back to 1979, has systematically stressed the spacer/film/spacer bond in excess of twice the actual
There are three important wavelengths to consider when selecting windows and glass: UV, visible light, and infrared. UV wavelengths can cause sunburns and fading in fabrics, and should be blocked; visible light is light that we see and should not be blocked; infrared wavelengths transfer heat (these are the wavelengths that make your car too

Passive solar heating is utilized in multiple design approaches and focuses on how combining various building elements in strategic ways can positively contribute to the heating, cooling, and daylighting of a building. Glazing is one of the most critical considerations for effective passive solar heating designs. Taking into consideration the orientation of a building’s windows
Alpen HPP units have been installed in over 10,000 residential and commercial projects, across extreme and high humidity climates, extending back to first installations in 1981. Architectural Project Gallery To review just a sample of our project success stories, click on our Project Gallery.
