The warm weather is here and many consumers are looking to make home improvements while sticking to a budget. BBB advises consumers to balance cost effectiveness with energy efficiency, as more efficient windows, doors and skylights can make a big difference in energy consumption over time.
1. If you are looking for a well insulated room, check the window’s U-Factor.
2. Is your room sunny and bright? The Solar Heat Gain Coefficient (SHGC) rates how much solar radiation is admitted through the window.
3. Are you looking for a well lit room or one that’s on the dimmer side? Visible Transmittance is an optical property that indicates the amount of visible light transmitted through the window.
4. Make sure your window doesn’t give off any unwanted breeziness. Heat loss and gain occur by Air Leakage through cracks in the window assembly. The lower the AL, the less air will pass through cracks in the window assembly.
5. Check to see how well your window will resist the formation of condensation. The higher the Condensation Resistance (CR) rating, the better that product is at resisting condensation formation.
