This fluid-applied, one-component membrane cures to form a resilient, monolithic, fully bonded elastomeric sheet when applied to construction surfaces.
The silyl-terminated polyether (STPE) liquid-applied air barrier does not wash off when exposed to light rain following application, avoiding weather delays.
Perm-A-Barrier VPL50 can be applied to a wide variety of commercial and residential exterior wall systems, including concrete block with a brick veneer or pre-formed cladding panels, and steel- or wood-stud walls with exterior gypsum sheathing, brick veneer, or pre-formed panels, plywood, and OSB.

New air-conditioning design standard allows for increased air speed to cool building interiors
Building occupants, who may soon feel cooler from increased air movement, can thank a committee of building science specialists. The committee in charge of ANSI/ASHRAE Standard 55 - Thermal Environmental Conditions for Human Occupancy—after months of study and discussion--has voted recently to allow increased air speed as an option for cooling building interiors. In lay terms, increased air speed is the equivalent of turning up the fan.

Study explains the financial value of green commercial buildings
Green building may be booming, especially in the Northwest, but the claims made for high-performance buildings have been slow to gain traction in the financial community. Appraisers, lenders, investors and brokers have found it difficult to confirm the value of high-performance green features and related savings. A new study of office buildings identifies how high-performance green features and systems can increase the value of commercial buildings.

Architecture Billings Index flat in May, according to AIA
After a slight decline in April, the Architecture Billings Index was up a tenth of a point to 42.9 in May. As a leading economic indicator of construction activity, the ABI reflects the approximate nine to twelve month lag time between architecture billings and construction spending. Any score above 50 indicates an increase in billings.

Free-span solar energy system installed at REM Eyewear headquarters
The first cable-suspended free-span solar energy system was completed today over the REM Eyewear headquarters parking lot in Sun Valley, Calif. The patented, cable-supported photovoltaic system created by P4P Energy is expected to generate 40,877 kilowatt-hours of renewable electricity per year, enough to power five to six single family homes and to prevent 1.5 million pounds of carbon from being released into the atmosphere.

Architecture Billings Index drops to lowest level since June
Another stall in the recovery for the construction industry as the Architecture Billings Index (ABI) dropped to its lowest level since June. The American Institute of Architects (AIA) reported the August ABI rating was 41.7, down slightly from 43.1 in July. This score indicates a decline in demand for design services (any score above 50 indicates an increase in billings).
