NFRC Announces First Spacers Added to CMA Software
July 7, 2010
The National Fenestration Rating Council (NFRC) announced that
PPG Industries and ADCO Products are the first spacer manufacturers
to submit products into NFRC's Component Modeling Approach Software
Tool (CMAST) database.
According to the announcement, PPG placed both its tin-plated steel
spacers and its stainless steel Intercept® spacers in the database.
Both types of Intercept spacer are available in 21 widths ranging
from 5.08 mm (0.200") to 20.96 mm (0.825"). ADCO's thermoplastic
spacer is available in 10 sizes, from 6.35 mm (0.250") to 20.65
PPG and ADCO products are configured in CMAST as 'Path III' spacers,
meaning they provide CMAST users with the ability to fully define
the geometry and effective conductivity (Keff) for each of the numerous
"This calculation occurs 'on the fly' with CMAST as THERM 6
is running in the background to complete thermal analysis of the
spacers once the CMAST user configures a spacer edge seal assembly,"
said John Lewis, NFRC's director, new business programs.
In related news, NFRC's board of directors decided to waive CMAST's
spacer and frame component fees for the remainder of 2010, in an
initiative designed to facilitate implementation of the Component
"Ordinarily, submitting these components into CMAST would require
a nominal per-component fee," said Jim Benney, NFRC's chief
executive officer. "The board, however, views waiving these
fees as an effective means to allow the CMA program to continue
to gain traction as a viable modeling tool that will ultimately
prove invaluable to the fenestration industry."
