Hygrothermal Performance Of A Building Insulation Material Case Study

Decent Essays

The increasing demand for housing and growing interest in environmentally friendly building designs motivates the investigation of the hygrothermal performance of the building insulation material. The water vapor transfer rate, water vapor permeability, water vapor permanence, water vapor absorption rate, thermal conductivity and thermal conductance are the key hygrothermal properties, which establish the performance index of the building insulation material. The building envelopes are subjected to the various environmental factors such as extreme temperature ranges from -40 degree to +50 degree, solar radiation, Wind energy, Rain [1]. The design of the building insulation material derived from the environmental condition of the specific …show more content…

The characterization of any building insulation material is evolved from the water vapor permeability (WVP) during these days. The effect of temperature on the WVP is determined during this testing. The results are evaluated with the existing results from the recent studies as per described in the ASTM Standard Test Method E96. The tests are compared on the basis of their WVT, WVP. The Four building insulation material used during the testing are 1) Siding Sheathing Paper 2) Stormtite Sheathing Paper 3) Gypsum Board 4) Plywood (3/8 inch). The three temperature ranges are adopted for each building insulation material which is 1) Low Temperature 2 to 3 degrees, 2) Room Temperature 22 degree and High Temperature 47 to 52 degree respectively. There is narrow information is available on the temperature dependency of the WVP for widely used building insulation materials and this testing establish the results and temperature dependency of the building insulation materials. Chapter 2: Objective and Project Layout The objective of the project is to investigate the hygrothermal
