properly installed insulation can dramatically in- crease the comfortof your home and lower your fuel bills so dramatically in fact that some homeowners cant resist rushing headlong t into the job this enthusiasm can be an expensive mistake insulation is safe and effective only if its correctly installed and if the proper materials are used take the time to do it right the first time v before you even begin insulating seal your house with caulking and weatherstip- ping to make it as airtight as possible wherever you can install an air vapor bar- rier as part of the insulation process this is a layer of impermeable material usually 6 mil polyethylene that you attach to the warm side of the insulation prov vided it is continuous and well sealed it will serve the double function of blocking air leaks and preventing moisture from seeping into the insulation or walls if installing a plastic air vapor barrier is impractical you can still protect your in- sulation by covering the walls with an oil- based paint and caulking around base- boards recessed lights electrical outlets and so on when youre ready to insulate you have the alternatives of hiring a contractor or doing the job yourself if you decide to con- tract out the work get several written esti- mates be sure the contractor you select is certified by the canadian general stan- dards board insist on a written guarantee that only materials listed by an approved standards group will be used s even if you opt for hiring a contractor you should know something about different insulating materials and methods when youre choosing insulation ask ab- out the cost the insulating value where the product can be used and how its installed whether it can withstand moisture and whether it is fireretardant with that in- formation in mind decide what would best suit your house and your budget here are the common types of insulation and some of their characteristics t fiberglass is inexpensive insulating value of rsi 021mm r 303in can be used throughout the house a frequent choice for attics and wall cavities avail able as batts or as loosefill which is blown or poured in place and needs an air vapour barrier

for the basement he spreads the fuel throws a match in a puddle and as the fire flares up he leaves the building a paid arsonist has torched another building this is the popular conception of an arsonist but while the paid torch is one of the most serious threats to society others are even more dangerous the young van- dal the mentally disturbed the angry per- son seeking revenge for some fancied in- jury all will strike the innocent property owner with perhaps even more devastat- ing results while the hired torch partner in an attempt to defraud an insurance company is responsible for a high proportion of the property loss in arson fires it is theran- dom action of the disturbed or mindless fire setter that poses the greatest threat to innocent victims of arson the number of arson fires in canada in- creased by 341 per cent from 1977 to 1981 from 8809 reported or known arson off- ences to 11816 insured losses from arson fires in- creased in the same period from just over i 25 million to more than 180 million approximately one half of all arson fires are set by vandals while fraud fires amount to from 10 to is per cent of the total inci- dents but fraud fire attempts account for up to 50 per cent of the dollar loss popular mythology has it that arson is i the hardest crime to prosecute because the evidence is burned this is not strict- ly correct traces of fuels used to start arson fire can be measured by testing room i air in a burned out building the modern investigator has many other sophisticated methods of determining the cause of a fire even if arson investigators are unable to i register a criminal conviction for fire sct- ting they may lay other charges arson is frequently accompanied by fraudulent insurance claims or other forms of fraud and if it- is impossible to make an arson charge stick it may be easier to get a fraud conviction an insurers final recourse to protect in- nocent insurance buyers from fraudulent i claims is to refuse to pay a suspicious claim and let the matter go before a civil court- where different legal rules apply making it more difficult for the arsonist to have his own way to help canadians fight the ever- increasing threat of arson the canadian i private sector propertycasualty insur- ance industry has developed an arson i awareness program for the canadian association of fire chiefs and the-insur- ance crime prevention bureau this program arson alarm is de- signed to help people work at the commun- ity level in cooperation with their local fire i department to reduce the arson menace for a free

ontario currently sets the recommended minimum insulation level at rsi 21 r 12 for walls and rsi 5 r 28 for the roof and ceilings which is being increased to rsi 56 or r 32 the minimums recommended for northern ontario are higher but remember that proper installation is at least as important as the rsi value re gardless of the insulation you choose fol- low these general rules when you install it orobserve your contractor carefully to sec that he does fill cavities and gaps completely to keep air from circulating except in places which require ventilation like attics dont compress batts or loosefill insula- tion in an effort to cram more into the space this does notmake it more effec r tive remember that insulation cant prevent i air leakage or the movement of water vapor for this you need a continuous well- sealed air vapour barrier only the warm side of the insulation- should be airtight the outer side should allow any vapor that gets through to escape always take great care when youre working around wires electrical motors fans and light fixtures these days insulation is still one of the homeowners best investments its re latively inexpensive and you can install it yourself or have it done for a reasonable cost w most of the money involved is spent on preparatory and finishing work so its eco nomical to combine insulating with home improvements if youre already planning
