Alpen High Performance Products, formerly owned by Serious Energy, offers high-performance fiberglass windows. Alpen windows use a combination of suspended low-emissivityAmount of heat radiation emitted from a particular body or material. Emissivity is expressed in a fraction or ratio, with the lowest values indicating low emissivity and the highest indicating the high emissivity of flat black surfaces. (low-e) Heat Mirror films, low-e coatings directly deposited on the glass, low-iron glass (which increases visible light transmittance), low-conductivity gas fill (including kryptonA colorless, odorless inert gas, often used with argon in fluorescent lighting and sometimes used as gas fill in high-performance glazing. and argonInert (chemically stable) gas, which, because of its low thermal conductivity, is often used as gas fill between the panes of energy-efficient windows. ), pultruded fiberglass frames insulated with soy-based foam, and low-conductivity glazingWhen referring to windows or doors, the transparent or translucent layer that transmits light. High-performance glazing may include multiple layers of glass or plastic, low-e coatings, and low-conductivity gas fill. spacers. These 3-1/4"-thick custom windows are available with a wide range of properties to meet different needs. The company's highest performing windows have a U-factorMeasure of the heat conducted through a given product or material—the number of British thermal units (Btus) of heat that move through a square foot of the material in one hour for every 1 degree Fahrenheit difference in temperature across the material (Btu/ft2°F hr). U-factor is the inverse of R-value. of 0.11.
