Panelfoam--a deary lightweight. expanded polystyrene ma terial. is supplied in six-board packages: exactly sued to fit between standard feniag strips behind any type of four by eight foot wall panel. Each package insulates one full ftff panel. Because expanded polystyrene is one of the most effective of the modem thermal insulating materials, it assures a warmer, drier basement It markedly reduces heat less through cold masonry, and eliminates a major cause of moisture condensation. Result: a more comfortable room tltrough all four season*. Then are other benefits. Paneiioam helps protect panels against moisture damage--which could cause warping or delaminating in extreme cases. Sound absorbent, it creates a quieter environment (The reduced noise transmission is espe cially noticeable when the young fry take over the new play room. I And it cushions wall panels against impact damage. The new insulation is about as easy to handle as anything ever produced for the borne handyman. Just nail the first furring strip in place with masonry nails and place a Panel- foam board snugly against it to locate the next strip. Nail the second furring strip in place, and fill out the space between the strips with another Pknetfoam board. Repeat the pro cedure across the entire wall. The material cuts easily with a knife or saw to fit odd-sized areas. _ Manufactured by the W. R. Grace Sc Co. Construction Products Division, the product is available through local building supplies dealers. Each package includes complete installation instructions. > 25055721 ' J-l* ; - - ; 1'C ... -r.->v ; I :-i\- > . <>> .- U r* -j. v*-,' CONSTRUCTION/TECHNOLOGY I .l.r* WaterpToofing systemis`pressure sensitive' f" -tii:S.<ittfiai-.
