The H Window was designed in Norway, where  homes are subject to environmental extremes.  These extremes range from severe arctic coastal conditions to cold weather blasts directly from the North Pole.


All of Norway lies north of the most southern part of Canada, and about a third of its land is north of the Arctic Circle.  The H Window was designed to insulate homes from sub-zero arctic blasts from the polar cap, while providing the home with the lasting beauty of a real wood interior.


Due to these extremes, the H Window exterior was engineered to be virtually maintenance-free with structural integrity unmatched in the window industry.


No operating window available can match the structural, air infiltration and water resistance of the H Window.


Obviously, if the H window can insulate and protect the homes of Norway against these extreme weather conditions, imagine the performance this window can achieve for your home.


No matter if your home is located in the scorching heat of the deserts of the Southwest... or the icy, windswept plains of the North... the H Window will insulate, protect and beautify your home.
