The
National Fenestration Rating Council
(NFRC) is a United States 501(c)3 non-profit organization which sponsors an energy efficiency certification and labeling program for windows, doors, and skylights.
What is the meaning of NFRC?
NFRC is short for the
National Fenestration Rating Council
, which is a non-profit that established standardized ways to test the performance of windows and doors. The ratings they offer give consumers detailed info about how energy performance, which gives them more information to make the most informed decision.
What is NFRC certification?
NFRC certification gives
consumers the assurance that your product has been rated by the world’s foremost expert in window, door, and skylight performance
, in addition to ensuring compliance. Plus, it gives your product added visibility in the marketplace by being listed in the NFRC Certified Product Directory.
What does NFRC 100 mean?
NFRC 100 is
a set of procedures and guidelines for determining the U-factors* of windows and doors
. NFRC 200 is similar to 100, except it is used to determine the Solar Heat Gain Coefficient (SHGC) and Visible Transmittance (VT) of windows and doors.
How do you read NFRC labels?
Here’s what you need to know and look out for when reading an NFRC label:
U-Factor
: The lower the U-factor, the better a product is at keeping heat in. U-factor or U-value measures how the complete window (glass and frame) prevents heat from escaping. Ratings generally fall between .
How do I get NFRC certified?
NFRC requires
certification by an accredited third-party agency
. The Inspection Agency of the manufacturer’s choosing reviews the submitted computer simulations and physical test reports to confirm product compliance. Once compliance is verified, the Inspection Agency issues the certification.
What is a good SHGC rating?
When it comes to an optimal SHGC rating, again you will want to look for a rating of
0.25 or less
for efficient energy performance and lower A/C costs. Although for people that like their home on the warmer side should choose a SHGC rating between 0.35-0.60 to allow natural solar heat in.
Is it better to have a higher or lower SHGC?
The lower the SHGC
, the less solar heat it transmits and the greater its shading ability. A product with a high SHGC rating is more effective at collecting solar heat during the winter. A product with a low SHGC rating is more effective at reducing cooling loads during the summer by blocking heat gain from the sun.
What is nfrc200?
ANSI/NFRC 200:
Determining Fenestration Product Solar Heat Gain Coefficient
. Scope: This test applicable to both residential and commercial fenestration products. … This typically is used to certify windows, doors, skylights and curtain walls for SHGC and VT and to qualify for Energy Star.
What is AAMA rating?
AAMA stands for American Architectural Manufacturers Association. An AAMA rating for fenestration is the standard for replacement windows and doors in Chicago by which companies products are accreted. The AAMA rating uses
“Performance Grade”
as a measurement rating.
What is clear low E glass?
Low-E glass has a microscopically
thin, transparent coating
—it is much thinner than a human hair—that reflects long-wave infrared energy (or heat). Some low-e’s also reflect significant amounts of short-wave solar infrared energy.
What is U-factor in windows?
U-Factor
measures the rate of heat transfer and tells you how well the window insulates
. U-factor values generally range from 0.25 to 1.25 and are measured in Btu/h·ft2·°F. The lower the U-factor, the better the window insulates.
How are windows rated?
Energy Performance Ratings
U-Factor ratings for windows 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. (The window’s insulating value is indicated by the R-value, which is the inverse of the U-value.)
What is a good U-factor for doors?
The range is from 0 to 1. SHGC measures how well a product keeps out solar heat. Look for a low U-factor; the range is from
0.00-2.00
. The lower the U-factor, the better the door keeps in heat.
What is nfrc400?
NFRC 400. is the National Fenestration Rating Council document titled “’NFRC 400:
Procedure for Determining Fenestration Product Air Leakage
.” (2017).
What is the meaning of fenestration performance?
Fenestration refers to
the openings in the building envelope
, including the installation of windows, doors, and skylights.
