CENTRIA
The MetalWrap Series has been expanded and is available for use
with brick, terra cotta, or metal. The design includes a
single thermal, air and moisture barrier back-up panel that can be
used with all three wall exteriors, or any combination of the three
in mixed-medium buildings, to help architects, owners, developers
and contractors build better walls. MetalWrap Series also meets
thermal and fire code requirements. The MetalWrap Series features
CENTRIA's Advanced Thermal and Moisture Protection that controls
moisture without sacrificing thermal efficiency. It combines
a super-insulating foam core with a durable metal rain screen,
air/moisture barrier and unique clips, anchors and supports that
are designed with the specific requirements of each building
material in mind.
Therm-All Insulation
Therm-All Insulation reintroduced Reflect-R, a cutting-edge
fiberglass core reflective insulation that deflects 97 percent of
radiant heat gain. The insulation product aids in condensation
control and maintains moderate indoor temperatures. It also
significantly reduces noise and vibration; naturally deflects solar
heat waves, thereby reducing energy and lowering utility bills; and
possesses heavy duty reinforced "printed" foil facings (3/4-inch
thick fiberglass core standard).
Rhino Hide
The patented Solar-SNAP Radiant Heat Barrier from Rhino Hide is
simply rolled into place. The product doesn't require
installers to crawl out onto insulation or hard-to-reach areas.
Available in 16-inch and 24-inch widths, the barrier fits in
between the trusses on the underside of roof decking. It can
also be easily removed and reinstalled for inspection, cleaning and
repairs. Perforated, Solar-SNAP Radiant Heat Barrier won't
trap vapor. Since the barrier doesn't impede ventilation within the
attic, air can flow freely behind it from the eave to the ridge
vents. This reduces moisture buildup, as well as potential mold and
mildew problems.
Firestone Building Products
Firestone's new V-Force Vapor Barrier Membrane doubles as a
reliable vapor barrier and self-adhered temporary roof, providing a
puncture resistant surface that withstands roof traffic. The SBS
adhesive in the membrane is suitable for use over a variety of
substrates, making V-Force an excellent solution for quickly
weatherproofing new or re-roofing projects. In addition, V-Force's
non-slip, UV resistant surface can be left exposed to the elements
for up to three months over an approved substrate. UL and FM
approved, V-Force is recognized by the International Building Code
as a Class l vapor retarder (perm rating = 0.02) and can qualify
for Firestone Red Shield Warranty coverage.
Metl-Span
Metl-Span has introduced the HPCI Barrier insulated metal panel,
a new air, water, thermal and vapor barrier panel that can be used
behind virtually any type of facade. The High Performance
Continuous Insulation Barrier back-up panels are available in 2-
and 3-inch thicknesses and provide R-values of 15 and 22,
respectively.
The HPCI Barrier offers a single panel system that controls air,
water and vapor without sacrificing thermal efficiency. The panels
are installed completely outside the structural supports and there
are no thermal bridges to reduce the energy efficiency of the wall.
The HPCI Barrier is quick and easy to install and provides an
economical solution to conventional air, water, thermal and vapor
control.
