Show Heat Waste Prevented by Felt Asbestos Cover When your cellar is hot and upstairs up-stairs rooms feel like a piece of ice, you are losing heat through lack of furnace and boiler insulation, states an announcement by n New York corporation cor-poration specializing in insulation and roofing. This condition is caused by faulty or Inefficient boiler, heating pipes and furnace. This great heat "loop hole" may be readily and cheaply stopped, declare engineers who have experience along this line, by the employment of a patented felt and asbestos insulation. This material, composed partly of the fireproof asbestos mineral, is one of the best known heat insulators, due to the fact that It has under its outer surface a numher of corrugations which act as obstructions to the passage pass-age of air, either hot or cold. Figures computed by the engineers show that it furnishes a high efficiency effici-ency primarily becnusp' of the type of corrugation used. This material may be applied with ease to "bare" pipes or boiler in from one to four or more layers, each layer appreciably lowering lower-ing fuel waste and increasing comfort. com-fort. 1 |
