Northerm Kodiak Windows

Double-Pane Windows

Double-pane windows are a staple throughout Alaska. But Capitol Glass Kodiak double-pane windows offer more than most others: Our 3 ¼”-wide frame and 7/8” glazing pocket allows for proper spacing between panes of glass for more argon fill. We use channeled frames and thicker material than other manufacturers do. This is why Capitol Glass windows can withstand winds up to 165 mph.

Our windows have better resistance to air and water infiltration because we seal them with rubber gaskets around the glass, not tape that can shrink and leak. All our insulated glass units have a foam spacer between the panes, not metal, like many other companies use. This prevents the contraction and expansion of not only the glass but the frame itself. Cold and heat don’t transfer through the glass as they do with most mass-market double-pane windows.

Triple-Pane Windows

Triple pane window

Three panes of glass are not enough to give you the benefits of a triple-pane window. True triple-pane windows require a 1-3/8” glazing pocket, creating the right airspace between the glass. This gives you excellent insulating and noise-reducing barriers. Available in picture, sliding, casement, awning and custom. 

Four-Pane Windows

Our quad-pane window is, quite simply, unmatched. If you want the best, this is it. Four panes of glass in 2″ glazing pockets add up to truly impressive insulation and noise reduction. This is yet another proven design our engineers developed to meet even our toughest extremes. Available in casement, picture and awning designs.  

Additional Windows

Prime 9000 Series Sliders

Multi-cavity, vinyl lineals improve thermal performance, help block heat transfer and enhance sound absorbency. The double-pane window uses a ¾” glazing pocket and the triple-pane version uses a 1-1/8” glazing pocket. PRIME 9000 windows’ energy-saving thermal efficiency and 3 ¼” frame depth provide outstanding structural integrity. Its beveled exterior frame provides beauty and elegance, and the self-aligning tandem rollers glide over a stainless-steel track for smooth, effortless operation.

PRIME also makes first-rate patio doors, casements, awnings and Euro-design tilt/turn windows.
