Park-Vue ™ patio doors have been performance tested and rated, in compliance with the national system established by the
NFRC (National Fenestration Rating Council). These ratings enable consumers to compare the energy efficiency of various
patio door and window products. Ratings appearing on the NFRC label include:
  • U Factor, or how well the unit keeps heat inside the home.  The lower the U Factor, the better the energy performance.
    (NOTE:  R Factor  = 1 / U Factor)
  • Solar Heat Gain Coefficient (SHGC), or how well a product keeps solar heat out of the home. 
    The lower the SHGC, the less solar heat the unit will transmit.
  • Visible Light Transmittance (VT), or the percentage of visible light that comes through the unit.
  • Condensation Resistance (CR) measures how well a product resists the formation of condensation.
    The higher the CR rating, the better that product is at resisting condensation
