Alpenglass Windows by Alpen Energy Group Alpenglass Windows by Alpen Energy Group

Alpenglass windows use a combination of low-E coatings; suspended Heat Mirror films; gas fills; vinyl, wood, or insulated fiberglass frames; and low-conductivity spacers to achieve whole-unit U-factors as low as 0.10 for fixed units and 0.14 for casements using superinsulating glazing combinations, such as triple films and xenon gas, and superinsulated frames. Depending on the customer’s requirements, the manufacturer can provide products with higher SHGC values for passive solar gain, or whole-unit SHGC values as low as 0.15. 800.882.4466. Read more

SageGlass Electronically Tintable Skylights by Velux SageGlass Electronically Tintable Skylights by Velux

SageGlass electronically tintable skylights allow control of the amount of light and heat that enters a room. Applying a safe, low-DC voltage via a control switch, remote, or automatic timer causes the electrochromic layers on the skylight to darken, and reversing the voltage polarity causes the layers to lighten. The skylights have a whole-unit U-factor of 0.49 and an SHGC of 0.10 when the skylight is dark or 0.47 when it is clear. SageGlass is available in select sizes of model FS and model VSE skylights, which are deck-mounted and have wood frames, as well as in select sizes of the aluminum FCM and wood VCE skylights, which are curb-mounted. The skylights are Energy Star–qualified. 800.888.3589. Read more
