In these cases, the only available specifications for the fenestration system are its bulk properties of U-factor and solar heat gain coefficient (SHGC), visible transmittance (VT), and air leakage (AL), as specified on the NFRC
label, along with other observable characteristics (i.e., if the fenestration is on an existing structure), such as the frame material, the number of glazing layers, glazing coating, gap spacing, etc.
The procedures for testing, conducted and certified by the NFRC
, provide the customers with energy performance numbers that can be trusted.
The new combined entity will enable NSU subsidiary NFRC
to underwrite and reinsure surety bonds through its licensed insurance carrier partner, Clear Blue Insurance Company, Inc.
Now, Figure 5 shows selected normalized load displacement curves corresponding to fracture test for FRC and nFRC
. Normalization was performed according to the maximum load achieved for each material.
GIK Institute in collaboration with Isotherm Inc., USA has established the NFRC
to provide refrigeration solutions on a global scale.
Obtaining suitable NFRC
properties depends on several factors such as type of lignocellulosic material (which is related to constituent content, microfibril angle etc.), fiber content, size and distribution, and interaction between fibers and matrix.
In 1996, after receiving a separate request from the National Fenestration Rating Council (NFRC
), NIST issued SRM 1453, Expanded Polystyrene Board, for use in the calibration procedure for testing windows in a hot box.
The thermal models for the prediction of the U-factor were compared with the measurement data taken from the certified product directory database of the National Fenestration Rating Council (NFRC
) and CFD simulations.
This information is usually included in a table of default U-factor for fenestration products without National Fenestration Rating Council (NFRC

The city firms have benefited from a range of training courses delivered by the National Federation of Roofing Contractors (NFRC
), with financial support through the Growth Fund, which is administered by CITB.
