Aluminum foil on a paper basis

Use of aluminum foil in designs of baths and saunas allows to keep as much as possible a full range of thermal radiation indoors. The foil provides fast heating and long preservation of heat at smaller costs of heating (EFFECT of the THERMOS). Installation of a foil in baths and saunas directly on a ceiling and walls under lining by the polished (mirror) party in the room gives notable thermal effect. Such scheme of a design quickly heats up and long keeps heat.
