Types of insulation are improved and the methods of inâ€" stalling them are réfined also. Insulation is becoming big by Kim Dadson Whether you decide to utilize the sun or a woodburning unit to supplement your home heating system, it will be necessary to properly insulate your home. "In 1977, we couldn‘t get it (insulation) fast enough,, says Ted Starling of Beaver Lumber, Elmira. A government grant system, which started that year, contributed to the greater interest in insulation. + : Insulation alone can make a major difference in your fuel bills, whether they be electric, oil or gas. o Homes in our cold, Canadian climate are built to protect us from the bitter winter climate, but unfortunately, there are many places in our homes where warm air gets out and cold air gets in. Doors and windows may be an obvious area to most hoâ€" meowners, but ceilings, walls and attics also contribute to a large amount of heat loss. Insulation makes a difference Energy Special The great thing about insulation is that homeowners can do most, if not all of the work. Types of insulation, their maâ€" terial properties and the methods of properly placing them should be studied. As the warm air moves outside, a vicious circle starts. The temperature is raised to keep the body warm and the warm body and room heat moves outside through uninsulatâ€" ed areas. Insulation works because it traps tiny pockets of air which cannot circulate. The heat cannot travel through the air and through the insulating material. According to "Keeping the Heat In", a booklet released by Energy Mines and Resources, Canada, ‘"The cost (of insulation) will be paid back through fuel savings in a maxâ€" imum of five years, usually less." _ * The interior of an uninsulated wall can to eight to 14 deâ€" grees cooler than an insulated wall. Room temperature could be lowered to what should be a comfortable level, but body heat will radiate to cold walls, ceilings and floors and as a result you will feel cold. Reitzel Insulation of Kitchener has done many homes in the region andâ€"services a 70 mile radius to as far as London and Toronto. A vapour barrier, made of polyethylene, should be applied to the heated side of insulation. The barrier goes on the room side of a wall, not behind the insulation next to the exâ€" terior wall. This will prevent moisture from reaching the insulation and destroying it. But the house should not be absolutely air tight and vents in the attic should allow proper ventilation. Any moisture that can escape should be allowed free passage from the exâ€" terior walls or attics. Outside caulking should not be done unless it is a major source of drafts, such as windows and ‘"We are really pleased; we‘ve saved about 35 per cent in our gas consumption. The best thing is comfortâ€"wise; there are no drafts and we are much more comfortable." ~~Dr. Gregory Mason of Elmira says he would recommend insulation to anyone after having his home done by Reitzel in June of 1977.
