New NAHB Research Center Report Reveals
Insulated Vinyl Siding is Driest Wall Assembly
Fullback® Insulated Vinyl Siding demonstrates the best moisture performance,
with the overall driest wall assembly regardless of indoor moisture conditions.
BEACH CITY, Ohio, February 8, 2012— The NAHB Research Center along with
Progressive Foam Technologies, the leader in siding insulation, today announced the
results of a new report that details the moisture performance of various exterior wall
constructions with elevated indoor winter humidity and seasonal moisture
injections.
Craig Drumheller, NAHB Research Center senior energy engineer and principal
author of the report, states that “Insulated vinyl siding demonstrated the best
moisture performance in the study, with the overall driest wall assembly regardless
of indoor moisture conditions.”
A field investigation of nine different wood-framed wall assemblies was conducted to
determine the moisture performance of various exterior wall constructions with
elevated wintertime humidity in two seasonal phases (40-45%RH for typical winter,
and 25-30RH in the summer) levels and
seasonal moisture injections between the
cladding and sheathing over a thirteenmonth period. The report compares the
nine wall pairs’ performance to each other
and the two phases.
Stud bay temperatures and humidity were monitored, as were moisture contents in
the exterior sheathing and the studs. Insulated vinyl siding and brick came out as the
two driest assemblies with the insulated vinyl siding being the least affected by
orientation. Stucco clad walls represented the wettest wintertime sheathings. Most of
the wall sections were greatly influenced by the indoor relative humidity; the only
wall system that was somewhat immune to the indoor relative humidity was the
insulated vinyl siding.
“We engineered our FullBack siding insulation to do both--reduce air and water
infiltration from the outside, and allow for an effective release of water vapor and
excess humidity from the inside,” said Pat Culpepper, president. “The NAHB Research
Center study verifies Fullback’s superior moisture performance, which is a key
consideration for building professionals and homeowners.”
About Progressive Foam Technologies, Inc.
With core competencies in product development and innovation, advanced process
technologies, and marketing for product commercialization, Progressive Foam
invented Fullback® Siding Insulation.
Progressive Foam manufactures contoured foam insulation made from expanded
polystyrene (EPS). Because the insulation foam is contoured to fill the gap between
the siding and sheathing, it delivers maximum energy efficiency, along with
durability, low maintenance, and lasting beauty.
Progressive Foam has also pioneered innovations in energy-efficient manufacturing,
while minimizing manufacturing waste. Progressive Foam is dedicated to fulfilling
increased demand for siding insulation for homeowners, builders and contractors
who are looking for ways to reduce energy consumption. www.progressivefoam.com
