Insulation reducing infra-red light heat transfer - involves reflective indoor surfaces permitting lower temp. acceptable heating

摘要

Heat insulation in a room is increased by counteracting infra-red heat transfer, using a set of reflective surfaces. The surfaces provided reduce this form of heat transfer by reflecting infra-red light back in the direction from which it originated. The system is esp. applicable to indoor wallpaper, permitting room temp. to be lowered by 6 deg. without the occupant feeling cold. A number of different materials may be used to form the reflective surfaces.
