Insulation wraps the house ina layer that stews the rate of feat loss. Insulation traps tiny pockets of air. This .air reduces heat loss by conduction and since air cannot cir- culate, heat loss by convection is minimiz- ed. It also blocks heat -radiation. An air - vapour barrier is used to ensure that. humidity from the house dues not enter the building structure and cause damage. The insulating material must be carefully chosen and installed so that it completely ankets the available space, otherwise heat .11 escape through the holes. If the material is compressed it will also be less effective. Bear in mind that the cold side of insulation needs to be ventilated to allow moisture to escape and prevent damage to the insulation and surrounding structures. There are four types of insulation — batt or blankets, loose fill, rigid or semirigid foams. All insulation materials are potentially hazardous and must be handled and in- stalled with care. Read the product in- structions closely. There are a number of safety , precautions you should follow when working with any type of insulation: • Never smoke near insulation. • Handle equipment carefully. Sprayers, brewers and foamers require special in- struction and practice. • Wear long sleeves with tight cuffs, loose, thick clothing and gloves. Insulation materials can easily irritate the skin. ' • Goggles should be worn if there is a possibility of insulation dust coming in con- tact with the eyes. • A nontoxic particle mask or breathing filter should be worn. • Hard hats are necessary to prevent head injuries, and to protect eyes and hair from -.. 1 ifixotiorip4ette00,. • Vacuurn fibres or dust if peSSibler;.,444.

No matter hew tight the house, some moisture will find its way into insulated areas. Adequate venting is essential to allow its escape to the outdoors. The basement can be insulated on either the inside or the outside. When working in- side, keep yourself and materials away from the flue pipe of the furnace, or any other source of heat. Watch out for knob and tube wiring that is in poor condition (thisi is more likely to be a problem in, an older house). And before you begin, be sure to caulk any cracks between the foundation and sill. - If yiki're working outside, it is gping to re- quire a lot of digging before the job really begins, so allow lots of time for, this gel). If any services such as gas, telephone or cable enter .your home underground, be sure to find out where before you start digging: Special care should be taken to prevent damage to exterior drainage pipes or tiles. If you don't haveithese, this is a,good time to install adequate drainage 'and waterproof exterior basementivalls. Walls are generally thernost difficult and most expensive part of the house to insulate, but if you decide to do the work yourself, be sure to follow the safety precautions listed above. In most cases, the advice or services of a professional will be required. NOTES: • 1 in. = 25,4 mm. • The RSI(R) values quoted here are averages for the materials listed and are repres- entative values only. Individual products may vary; be sure to check the packaging. • Proper installation of blown, loose -fill insulation requires an experienced, well- trained technician. • Althoughit is possible to insulate enclosed walls that are open at the top with pouring insulation, it may be difficult to do a good job because of obstructions in the wall cavity, voids in insulation coverage and settling of the insulation material. The cost may not be justified. • Cellulose fibre is regulated .by Consumer and Corporate Affairs Canada. This ensures that all cellulose fibre sold meets strict guidelines for flammability, corro- siveness, smoulder resistance and chemical separation. • A vapour barrier must be used with all insulation. It must be applied to the v arm side of the insulated surface. All air leaks must be sealed to ensure vapour barrier continuity. • All thermal insulation materials will lose thermal resistance when wet ..Most \yin dry with little effect on the RSI(R) value., Start saving today! - ULTRAMAX: IIEWMAS High -Efficiency Gas FurnaCes Duomatic Oken.
