Description
A comprehensive, multi-institutional project, funded largely by the American Society of Heating, Refrigerating and Air- Conditioning Engineers, Inc., on ventilation drying in screen-type enclosure wall systems was recently completed. The project encompassed laboratory testing, field testing, and computer modeling. This paper presents the results of that portion of the laboratory testing program that was directed at evaluating ventilation drying in walls with vinyl siding claddings. These tests involved full-scale wall panels with vinyl siding. For the tests, three 1.2 × 2.4 m (4 × 8 ft.) wall panels, each with a spun-bonded polyolefin sheathing membrane, were constructed, instrumented, and then tested under different climate conditions. Testing was carried out in the climate chamber test facility in the Building Enclosure Testing Laboratory at Pennsylvania State University. Three representative climates were imposed, namely, winter in Minneapolis, Minnesota, fall in Baltimore, Maryland, and summer in Tampa, Florida. Consideration was also given to exposure to solar radiation. The primary focus of the study was on the nature and extent of ventilation drying in each wall system with different physical parameters. Vinyl siding was representative of a low mass, air permeable, and nonstorage cladding. Performance with respect to the extent, nature, and rate of ventilation drying was studied.
