The effectiveness of an insulating material is measured by its resistance to heat passing through it. This is called the resistance -value or R - value of insulation. The higher the R -value, the more effective the in- sulation. Insulating, material should bepurchased according to the R -value, not just the thickness. One inch of glass fibre insulation has the same R -value as 40 inches of concrete. R -values are clearly stated on in- sulation wrappers and containers. There are many in- sulation materials on the market. Flexible in- sulation made from glass fibre or mineral wool is the most common. It comes in four -foot long batts or in blankets cut to length by the installer. Both are fire and moisture resistant and easy to install. The R - value for flexible in- sulation is 2.9 to 4.0 per inch, according to the type used. Loose -fill insulation is available in glass fibre, mineral wool, cellulose fibre and vermiculite. This insulation is sold by the bag or bale, can be poured into unfinished attics, or blown into the attic space or wall cavity. Depending on the in- sulation type and method used R -values vary between 2.1 and 3.6 per inch. - Rigid -board insulation is used in the insulation of basement walls and in new construction. R - values range between 3.4 and 6.0 per inch, but great care must be taken in installation or the in- sulation may be a fire hazard. Rigid -board and foamed insulations must Stop lucks .. .

Foamed insulation is the new insulating material. This method applies foam inside the finished wall and attic cavities. Special equipment and highly skilled contractors are needed for this process. R -values for foamed insulation vary between 2.5 and 2.8 per inch. Recommended R - values for each area of the house are the following: for ceilings, R- 28; for walls, R-12 (ex- cept for solid masonry), R-8 if less than 50 percent of basement walls are above ground, R-12 for more than 50 percent. Cathedral ceilings, built over unheated garages or unheated crawl spaces, should be insulated to R- 20. Home insulation is a one-time investment which pays long-term dividends in money saved, energy consumed and your comfort. gamegimmem INSTANT - PATCH It stops roof Teaks. • Just brush on .roofs, flashings , and 'gutters; trailer roofs, leaky seams. • No spe- cial tools, nails, rooting paper. • Exclusive self - reinforcing for- 3BMW_ NID mula contains TMSIFIIB bristles and fibers.
