Analysis of climate conditions in crawl spaces with high insulated wooden floor plates for the prevention of structural damages

Highly insulated wooden floor plates in combination with crawl space constructions for foundations of residential and functional timber-buildings were more frequently applied in the last years. Missing knowledge of microclimatologically conditions in crawl spaces and the resulting boundary conditions for timber and wood-based panels led to various constructional designs. By long term in-situ measurements and laboratory tests, design principles which guarantee a durable use of wooden floor plates in combination with air ventilated crawl spaces were developed. For German climate a rating to use class 1, of EN 335 (class 0 according DIN 68800) becomes possible.      «
