Air Barrier Systems

Air barriers are designed to control air leakage into buildings in order to significantly improve thermal performance for greater efficiency and comfort. High-quality air barriers are designed to seal an entire above-grade building envelope and come in impermeable or permeable options to meet project-specific design requirements.

EPRO’s air barrier products are designed not only to control air leakage but to also control moisture vapor as well.

Ecoflex-S

ECOFLEX-S is designed to be an air and moisture vapor barrier membrane for a variety of above-grade surfaces including concrete, block, gypsum and metal for cavity walls. It is applied with a unique, self-contained sprayer to produce an instantaneous, monolithic membrane with excellent adhesion.

ECOFLEX-S is a low-viscosity, water-based, anionic bituminous/asphalt emulsion modified with a blend of synthetic polymerized rubbers and special additives, which is highly reactive and exhibits exceptional bonding, elongation, vapor retarding and build characteristics.

It performs as a non-permeable air barrier while being non-hazardous, non-toxic and fire-resistant (VOC compliant). Its noteworthy tensile strength, in addition to its weather-resistant qualities, makes it a superior air barrier. ECOFLEX-S has an instant build, allowing for applications in inclement weather and eliminates the risk of shrinkage, saving time and money.

ECOFLEX-S should be applied to clean, dry surfaces, and with any adjacent surfaces protected from contact with the substrate. It should be stored above 40℉ and exposure to UV should be limited. You cannot apply a solvent-based product overtop.

Ecoflex-R

ECOFLEX-R is designed as a moisture and vapor barrier membrane for cavity wall construction that may be applied on a variety of surfaces including concrete, concrete block, metal and dense glass. It should be applied by roller or sprayer to form a monolithic air barrier. It can also be used as waterproofing adhesive for insulation board and as a base coat for other water-based coatings.

ECOFLEX-R is a medium viscosity water-based, polymer-modified anionic bituminous/asphalt emulsion, which exhibits excellent bonding, elongation and waterproofing characteristics, along with being non-hazardous, non-toxic and non-flammable (VOC compliant). ECOFLEX-R is not affected by ponded water, and it may be applied to green or uncured concrete and to damp surfaces. Its rapid setting allows the job to be completed in one application, making it extremely efficient.

ECOFLEX-R should be applied to clean, dry surfaces, and with any adjacent surfaces protected from contact with the substrate. It should be stored above 40℉ and exposure to UV should be limited. During warm weather, application in 20-mil layers is recommended. You cannot apply a solvent-based product over top.

Ecoflex-PS

ECOFLEX-PS is designed to be a permeable membrane for cavity wall construction that may be applied on a variety of surfaces including concrete, concrete block and dense glass. It should be applied by roller or sprayer to form a monolithic, vapor-permeable air barrier.

ECOFLEX-PS is a medium viscosity, water-based, copolymer latex emulsion. This product offers excellent elongation and recovery, and it exhibits durability, great bonding and waterproofing characteristics. ECOFLEX-PS is non-hazardous, non-toxic and nonflammable (VOC compliant), making it a great option for an air barrier.

Its rapid setting qualities allow for the job to be finished in one application, making it affordable and time-conscious. Because it is water-based, it can be applied to damp surfaces.

ECOFLEX-PS should be applied to clean, dry surfaces, with any adjacent surfaces protected from contact with the substrate. It should be stored above 40℉ and below 120℉. During warm weather, application in 20-mil layers is recommended. You cannot apply a solvent-based product overtop.
