摘要:
A bushing formed of insulation that can be installed in holes drilled in wood framing components, used to construct a building, such as a dwelling, these holes are drilled so plumbing pipes & electrical wiring can be installed in said framing components.Purpose of this invention is to close off & insulate these holes before the articles are installed, or after they are installed, either method would greatly reduce infiltration & heat transfer through these necessary drilled holes, reducing the energy usage in said building, helping our Countries energy conservation program.
摘要:
A method of providing thermal insulation in relatively small spaces, such as the spaces between window and door frames and the structural members forming the rough openings therefor, comprises use of a prefabricated compressed-insulation tape, which may be secured at the factory to the outer periphery of the window or door frame, or to the inner periphery of the rough opening on the building site, the tape comprising a strip of any suitable compressible insulation material, such as spun glass or polyurethane, for example, retained in a compressed state by means such as a paper or plastic envelope, the envelope having at least one rip cord, whereby when the rip cord is pulled after installation of the window or door frame to rip the envelope longitudinally off the tape, the compressed insulation expands to fill the air gap space between the frame and the rough opening structure to provide thermal insulation therefor.
