On September 30, NFRC (National Fenestration Rating Council) said that it had designed labels for energy-performance that will guide homeowners and contractor in window replacement, but the codes and labels can be very confusing.

Replacement windows generally have labels coming with them, indicating the efficiency of their energy, but not many know the meaning of the labels. Thus, homeowners have been asked to make sure they have learnt how to go through the labels so that they are sure of the best windows auguring well with their house.

People are ending up concerned with the surroundings every passing day, as well as the rising energy cost, as many choose more products that are energy efficient as they improve their homes, and no exceptions is made when it comes to choice in window replacements.

NFRC is a leader in the rating of certification and energy performance programs (non-profit organization) for all window products. Any contractor or homeowner can easily find NFRC’s label on replacement windows’ upper left corner, which depicts the certification of the manufacturer as well as whether the window performance is also in tandem with the standards of NFRC. Another label on the upper right corner highlights the materials, style, model and the manufacturer.

Contractors and homeowners considering reviews of replacement windows looking for energy performance types of ratings have been told to search for U-factors. These U-factors show the heat loss rates that a building might have, falling in between 0.20-1.20. If a U-value is low, the resistance is greater and the better the value of insulation. An inverse of a U-value is the R-value, showing the insulating windows value.
