Distributed in the U.S. by Four Seven Five, Pro Clima offers a full line of VOCVolatile organic compound. An organic compound that evaporates readily into the atmosphere; as defined by the U.S. Environmental Protection Agency, VOCs are organic compounds that volatize and then become involved in photochemical smog production.-free, pressure-sensitive air barrierBuilding assembly components that work as a system to restrict air flow through the building envelope. Air barriers may or may not act as a vapor barrier. The air barrier can be on the exterior, the interior of the assembly, or both. tapes designed for interior and exterior use in wall assemblies marketed toward Passive HouseA residential building construction standard requiring very low levels of air leakage, very high levels of insulation, and windows with a very low U-factor. Developed in the early 1990s by Bo Adamson and Wolfgang Feist, the standard is now promoted by the Passivhaus Institut in Darmstadt, Germany. To meet the standard, a home must have an infiltration rate no greater than 0.60 AC/H @ 50 pascals, a maximum annual heating energy use of 15 kWh per square meter (4,755 Btu per square foot), a maximum annual cooling energy use of 15 kWh per square meter (1.39 kWh per square foot), and maximum source energy use for all purposes of 120 kWh per square meter (11.1 kWh per square foot). The standard recommends, but does not require, a maximum design heating load of 10 W per square meter and windows with a maximum U-factor of 0.14. The Passivhaus standard was developed for buildings in central and northern Europe; efforts are underway to clarify the best techniques to achieve the standard for buildings in hot climates. construction projects. Most tapes are 2-3/8" (60 mm) wide, but the tapes range in width from 1"–3-3/8" (25–85 mm). Tapes with separate backing papers for use in corners are available. Pro Clima tapes adhere to a wide range of substrates, including OSB, soft wood, and masonry, although Pro Clima recommends the use of its Tescon Primer in some cases. Tescon RP primer is fluid-applied and requires no drying time before the tapes can be applied over it. According to Four Seven Five, Pro Clima tapes bond in several hours and, once dry, adhere extremely well. However, long-term testing data to support their durability is not available.
