Download Water Vapor Transmission Measurement and Significance of Corrections Book in PDF, ePub and Kindle
Water vapor transmission properties of building materials play an important role in the overall moisture management and durability of the exterior building envelopes. The cup method, as described in the ASTM Standard Test Methods for Water Vapor Transmission of Materials (E 96), is widely used in North America and other parts of the world for this purpose. Recently the latest ASTM standard (E 96/E 96M-05) has started taking into account various corrections (e.g., buoyancy correction, correction for resistance due to still air and specimen surface, edge mask correction, etc.) while analyzing the results obtained from the cup methods. This paper presents the results obtained from the laboratory tests carried out on more than 50 building materials. These results have been used to demonstrate the significance of various corrections on the measured water vapor permeability or permeance of various commonly used building materials or components. The results presented in this paper were discussed in the ASTM technical task group to underline the importance of various corrections for the calculation of water vapor transmission properties of various building materials.

Download Use of the Modified Cup Method to Determine Temperature Dependency of Water Vapor Transmission Properties of Building Materials Book in PDF, ePub and Kindle
This paper describes a modified cup method and its application to investigate the effects of temperature on the water vapor transmission (WVT) properties of building materials. The modified cup method is a simple and versatile technique that allows the user to vary the temperature condition of the test without altering the relative humidity. Two commonly used building materials considered in this study were fiberboard and gypsum board. The five temperature levels under consideration were between 7°C and 43°C. The WVT properties were measured at 50 % average relative humidity. The results obtained from these tests are critically analyzed and reported in this paper. These results demonstrate that there is a steady exponential increase of WVT rate, through both the materials tested, with temperature. However, water vapor permeability (WVP) through the materials shows no significant change due to the variation of temperature between 7 and 43°C. The general observations made in this study confirm that the modified cup method could be used reliably to measure WVT properties of building materials. Detailed analysis of the test results also reaffirms the fact that, for fiberboard and gypsum board, at 50 % average relative humidity condition, the WVP is not dependent on the temperature condition.
