We know that adding new windows is a great investment in any home. Windows can account for 20% to 25% of the total heat loss and 45% or more of the building’s designed cooling load in a typical house. With windows, you have eight or more basic frame types, six or seven glass options, and different warm-edge technologies, not to mention argon and krypton gas fills. Mix in NFRC ratings, U-factors and solar heat gain coefficient, you need a source that understands your needs and can fulfill them, while explaining all of your options. That’s why we carry the best- Marvin, Andersen, Integrity, Gerkin and Hayfield. At Kruse Lumber, you will find what you need to add more sunlight, warmth, comfort and style to any room or space.
