Supplemental obstacles result from constructing-code specifications that inadvertently or indirectly enhance the threat of humidity difficulties. Most codes involve passive or Energetic air flow of crawl spaces. That requirement causes it to be difficult to build a crawl space that is provided as part of the conditioned Room or simply Within the thermal envelope (Highly developed Vitality, 2001). If rainwater and groundwater are saved out, sealed insulated crawl spaces are frequently drier than ventilated kinds. The entry of warm, humid out of doors air into ventilated crawl Areas, which are typically cooler than outdoor, serves like a humidity source for that crawl spaces.
Numerous roofing materials are impermeable to liquid h2o and may be repeatedly wetted and dried without the need of problems. Wood shingles and thatched roofs are exceptions. They drain the bulk of rainwater faraway from the interior but also take up several of it.
