_ the market ome basic h With some warm, sunny days left to enjoy, it is hard to turn your mind to snow, rain and bone-chilling winds. Nevertheless now is the time to think about winter and home insulation before you are forcefully reminded by the sound of your furnace working overtime. If you are for home insulation, here are some basic facts about insulating matenials. Most insulation works by trapping air in tiny pockets, thus slowing the movement of heat from the inside to the outside of the building. The measurement of any matenal’s ability to reduce this heat transfer is called its “R” value or thermal resistance value.

The “R” value of insulating material should appear on _ the material or its container. The first step is to determine how much _ in- sulation you now have, its condition, and its efficiency. There are a number of ways to do this and these are explained well in the book “Keeping The Heat In”, available free from _ the Federal Department of Energy Mines and Resources. You might well opt for the computer analysis offered by the federal energy depart- ment. It's simple and free. Fill out an = “Enersave™ questionnaire, and a NN bringing Asking computer analysis pinpoints areas in your home where insulation can be increased. The analysis also gives tips on other’ fuel-saving measures. Vastly increased con- sumer interest in insulation has stimulated the production of insulating materials designed to fit almost any need. Generally, the best way to classify the types of insulation is by their method of installation. BATT OR BLANKET TYPE This is the kind of in- sulation generally used in new construction.The most common substances. are glass fibre or mineral fibre. The batts or blankets come in various thicknesses.

The “R” values of these materials vary considerably. All can be poured by hand — as you might do in an attic on top of existing insulation — or machine-blown into the outside walls of a house. Loose fill insulation usually costs less per unit of “R” value than batts or blanket types. FOAMED-IN-PLACE INSULATION There are essentially two types of foamed-in-place insulation used in Canada today — urea formaldehyde and polyurethane. The latter RICHMOND 8271 WESTMINSTER HWY ., RICHMOND 273-6181 WEST & NORTH VANCOUVER 103 PARK ROYAL SOUTH WEST VANCOUVER 925-1111 C17-Sunday News, September 21, 1980 has not been accepted by CMHC for houses insured under the National Housing Act or for the Canadian Home Insulation Program. Urea formaldehyde is ac- ceptable only for use in empty wood stud wall spaces. There have been problems with urea formaldehyde foam, usually due to im- proper installation. Urea formaldehyde foam is produced on site by the contractor who combines two liquid chemicals. Both the preparation and = in- stallation must be correct to avoid the production of urea formaldehyde gas, a possible irritant to the human respiratory tract.

One final disadvantage, the “R” value of most urea formaldehyde foam insulations’ will decrease over time as the foam shrinks. RIGID BOARD INSULATION Several synthetic sub- stances come in the form of rigid board insulation, ali with relatively high “R” values. This kind of in- sulation is generally used in basements or on the exterior of non-combustible walls. If used inside, they should be covered by gypsum board or other suitable protection against flame spread.
