Insulated Glass Unit

There are two basic types of insulated glass units which are fabricated at Green Mountain Insulated Glass, Inc. The first is the dual seal-silicone/PIB unit which has a much greater longevity than IG units fabricated with other types of sealants used with metal spacers. We routinely stock many choices in clear and colored anodized spacers as well as mill finish and white painted spacers. Different color spacers are sometimes not available in all sizes, but Green Mountain Insulated Glass will consider stocking any size for substantial orders.

Two-Pane CutawayThe second type is a reverse dual seal IG unit made with warm edge Superspacer. This spacer product is made of a type of foam and promotes less conductivity of cold through the spacer. Green Mountain Insulated Glass routinely stocks gray, white and black in several different sizes of each.

Our insulated glass exceeds common practices and quality in the careful construction of our IG units. We use high strength butyl (which outlasts other more commonly used PIB and hot melts), the highest quality silicone secondary seal, the highest quality of tempered glass, and washes both surfaces of the glass in the unit before assembly. Our glass is always cut precisely to size and correctly aligned for a proper fit into the glazing cavity. Green Mountain Insulated Glass, Inc. sightlines are always straight and true. Careful application of PIB onto metal spacers maintains tight sightlines for quality work.
