Eco Depot Inc. announced the following ASTM E-96 Water Vapor Transmission test results in accordance with the IBC International Building Code & IRC International Residential Code Vapor Retarder Specifications on its Bronya Climate Shield Fa?ade and Aquablock product line. Bronya Canada Group submitted Bronya Climate Shield Fa?ade and Aquablock Product for testing at SEREX Labs, a Canadian Government approved testing center to conduct American Standard Testing Method (ASTM) tests. ASTM E-96 was used to determine the water vapor transmission for outdoor use. The six fiber cement samples coated with the "BCS Aquablock" and "BCS Facade" formulations (two coats of 10 mils wet) were installed inside stainless steel trays (Figure 1) in order to seal the perimeter of the samples with a mixture of beeswax and rosin (50/50). The trays are fitted with a cavity at their base allowing an average quantity of water of 275g to be placed in order to simulate outdoor exposure with a relative humidity content of 100%. The painted surface of the sample faced the water in the tray, while the unfinished portion was exposed to ambient air. When mounting the samples in their respective trays, a minimum distance of 6 mm between the sample and the water was observed. The initial mass of the six assemblies was taken, then they were installed in a conditioning chamber adjusted to a temperature of 23°C ± 1°C and a relative humidity of 50% ± 2%. Subsequently, a daily mass gain was performed excluding weekends. The measurement took place over a period of six weeks in order to obtain the loss of mass as a function of exposure time (g/h) allowing the transmission of water vapor to be calculated. Permeance is the degree to which a material allows the flow of water vapor. It is expressed by measuring the mass of water that passes through a material per unit of time, area and vapor pressure difference on either side of the material. The higher this value, the more easily the vapor passes through the wall. Thus, a material is said to be impermeable or vapor barrier if its permeance is less than 57 ng/s · m2 · Pa (<1 US perm), semi-permeable between 57 and 570 ng/s · m2 · Pa (1- 10 US perms) and permeable above 570 ng/s · m2 · Pa (> 10 US perms). It is estimated that the total cost for repair, rehabilitation, strengthening, and protection (including waterproofing) of the concrete structures in the U.S. is $18 to $21 billion a year. Façades, Balconies, Plaza Decks, Exposed Concrete Airborne chlorides, freezing-and-thawing cycles, and carbonation are some of the distress mechanisms that may be related to design and construction errors. Waterproofing failures are also common, and seismic retrofits may be needed. Repair methods include foundation waterproofing, plaza deck waterproofing, and replacement or repair of balconies. This market is alone valued at 2 Billion USD per year according to the Concrete Repair Bulletin. These ASTM E-96 tests further prove efficacy in water vapor transmission of the product's application on foundations and envelopes (Facades). Note that about 15% of all heat loss is through the floors, basements and facades of commercial, industrial, and residential buildings.
