The Energy Star Label is Important for New Windows and Installation in Swansea

 

One of the most important considerations about new window Installation in Swansea is understanding the ratings that represent energy savings, and protect the house from heat penetration in the summer and heat escape in the winter.

First, look for an Energy Star rated window. In order for manufacturers to apply the Energy Star label to the window, manufacturers must test the FENESTRATION products according to independent testing at National Fenestration Rating Council (NFRC) approved laboratories. Fenestration is a Latin word for windows. As used in the rating procedures, it refers to any opening in a building structure to accommodate a window. The NFRC labels provide accurate information on the energy ratings for the window to which it is affixed.

The NFRC label provides ratings for all of the features measuring how well a product will prevent heat from escaping through the window. The lower U-factor ratings indicate the better product. This is important information during the winter heating season.

The NFRC label may indicate the solar heat gain coefficient (SHGC), which is required, and visible transmittance (VT). The label may indicate air leakage and condensation resistance. The SHGC measures how much solar energy is blocked from the sun. The lower number between 0 and 1 indicates that more solar heat is being blocked from the sun. This is important in the window Installation in Swansea.

The VT measures how much light can enter through a product. This data is expressed as a number between 0 and 1, with a number closer to 1 indicating a higher potential for more daylight entering through the window.

Air leakage is measured by how well the window prevents outside air from entering the home through a window. This rate is measured and reported as between 0.1 and 0.3. Obviously, the lower the air leakage allowed by a window, the better the window is at keeping outdoor air out.

The condensation resistance is measured by how well the window will resist the formation of condensation. This value is expressed by a number between 1 and 100 with a higher number indicating the window has a better resistance to condensation, which is a good attribute.
