This Crawl Space in New Hyde Park, NY was insulated with a Crawl Space Encapsulation System. All vents and other air leaks to the outside are sealed. The crawl space walls are insulated with SilverGlo foam board insulation with a reflective radiant barrier face. Then a dimpled plastic drainage matting is installed on the floor to create an airspace and thermal break. Finally a heavy duty, 20 mil thick crawl space encapsulation linear is installed permanently across the dirt floor- sealed with mechanical fasteners to the walls and spiked to the floor.
