Connecticut BBB Helps Consumers Compare and Choose
The warm weather is here and many consumers are looking to make home improvements while sticking to a budget. Connecticut BBB advises consumers to balance cost effectiveness with energy efficiency, inasmuch as more efficient windows, doors and skylights can result in significant long term energy savings.
Start by looking for products that carry the Energy Performance Ratings label from the National Fenestration Rating Council (NFRC). The label can help determine how well a product will perform its key functions - helping to keep your home cooler in the summer and warmer in the winter, keeping out wind and resisting condensation. Information on the label enables builders and consumers to reliably compare one product with another, and make informed decisions.
As with any home improvement project, it’s important to make sure you are dealing with a reputable contractor and high quality materials. Connecticut BBB encourages consumers to consult with their home contractor to see that all energy performance materials carry this information label.
If you are looking for a well-insulated room, check the window’s “U-Factor” - During the cold winter months, you’ll want to make sure your windows are trapping heat. U-Factor ratings generally fall between 0.20 and 1.20. The lower the U-value, the greater a window's resistance to heat flow and the better its insulating value.
Is your room sunny and bright? - The Solar Heat Gain Coefficient (SHGC) rates how much solar radiation is admitted through the window. SHGC is expressed as a number between 0 and 1. The lower a window's solar heat gain coefficient, the less solar heat it transmits in the house.
Are you looking for a well-lit room or light that’s more muted? - Visible Transmittance (VT) is an optical property that indicates the amount of visible light transmitted through the window. VT is expressed as a number between 0 and 1. The higher the VT, the more light is transmitted.
Make sure your window doesn’t give off any unwanted breeziness - Heat loss and gain occur by Air Leakage (AL) through cracks in the window assembly. The lower the AL, the less air will pass through cracks in the window assembly.
Check to see that your window will be free from any water leakage - The higher the Condensation Resistance (CR) rating, the better a product is at resisting formation of condensation. While this rating cannot predict condensation, it can provide a credible method of comparing the potential of various products for condensation formation. CR is expressed as a number between 1 and 100.
