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.      «
