And people are be- coming more and more aware of..the. need_to. conserve: But perhaps one of the largest areas of energy waste is being ignored. The walls of most private homes have lit- tle or no insulation, even though they represent an op- portunity for significant en- ergy savings. Certainly, a wall is one of the more difficult areas in your home to insulate. It is relatively easy to add insula- tion in the attic, or beneath the house in the crawlspace :- basement. You can't take the same approach- with a wall. There are two ways to in- sulate a wall. One is to blow insulation into the wall cav- ity. But this means drilling holes through the outside wall of your home, which later must be patched to match the exterior finish. 'ARO; the 'lnsufiatto i often doesn't fill the wall com- pletely, because of obstruc- tions in the internal framework. And many in- sulating materials will settle in the wall cavity, which re- duces their insulating value. Finally, this method doesn't insulate the entire wall since there is no insula- tion over the studs. The other alternative is to apply an insulating layer to the outside of a house, then cover it with siding. But Wbat materials should be used for the job'? First off, standard insula- tion, such as fiberglass bat- ting, won't work because of space limitations. If it's applied to the wall, then compressed by the siding, it loses nearly all of its insula- tion value. Also, it may trap moisture. Many contractors are turn- ing to an insulation board of one form or another. • These materials, usually one-half inch thick or greater, provide the same in- sulation value as a much thicker layer of standard in- sulation, depending on the composition of the board. •A new aluminum foil - covered insulating board sold by Reynolds Metals Com- pany, called Climate Guard, can reduce heat loss through uninsulated walls by as much as 59per cent, depending upon the type of siding in- stalled over it. And since the hoard is lightweight and easy to apply, labor costs are low. \ Which brings you to the next decision—what should you cover the insulation with'? Of all the available type's of siding, aluminum siding is the most preferred mater'aI, at least judging from h storical sales. It has been on the market for almo.•t 40 years and cov- ers mor than 10 million houses in the United States. Today, s x times as much aluminum siding is sold as compared to any other mate- rial. Aluminum is the lightest of any of.the metal siding mate- rials, which makes it easier to - install, cutting labor costs. It comes in a wide range of col- ors and styles, and reduces maintenance by eliminating the need for constant repaint- ing. BEAT THE HEAT Take the heat out of the kitchen by installing an exhaust fan in a convenient window. It'll do double duty by helping to keep the rest of the house aired out. Depending on the indi- vidual product, it carries a limited warranty up to 40 years. Specimen warranty certificates- are ava'il'able` through individual dealers. Also, the siding will not red rust, an important considera- tion in many areas; and soffits, shutters and down- spouts made of aluminum can be color coordinated to add character to a home. Steel siding, slightly more expensive than aluminum, is also available in a wide range of colors and styles. Because of its heavier weight, steel also costs more for installa- tion. The main drawback to steel' is its susceptibility to red rust. Vinyl plastic siding is used for conventional residing work, but in some cases, its application.over plastic foam insulation board is prohib- ited. Traditionally it's only been available in white and pastet,cplocs ,and, in.,limited... styles. Since vinyl's expansion/ contraction ratio under tem- perature change is higher than any other conventional siding material, it has to be installed more carefully; and vinyl, like most plastics, is susceptible to brittleness in cold temperatures -and• after prolonged exposure to sun- light. Also, vinyl plastic can burn. Regardless, the first thjpg to do when choosing siding is to ignore the rumors you've heard. Many people think that metal siding will attract light- ning, for example. Not true. Lightning has no preference for tiny material. The deter- mining factor is height. The tallest object in ari area will attract lightning, regard- less of composition. If this weren't the case, lightning would never strike trees. Another false rumor about metal siding concerns TV and radio reception, proba- bly started when someone noticed their car radio fading,.: --When=: passing over„ ti-'`irrid'ge .: with a metal framework. Ac- cording to independent laboratory experiments, metal siding causes Tess TV interference than leaves on surrounding trees. Interference essentially is a function of mass, and it's ridiculous to compare the amount•ofatuminum' Or steel' -' used in a siding job with the thousands of tons of steel needed to build a bridge. In. choosing a siding mate- rial, also think in terms of maintenance savings—it will make a big difference in your budget. Aluminum siding is the easiest to maintain. And when you remember that most houses have to'be repainted every five years, the longer your siding job remains intact, the more money you .save. That's something most people don't realize. Assuming professional painting on a five year cycle, in most cases insulated aluminum siding can pay for itself in less than 10 years through savings in mainte- nance, painting and energy. o..tbtuk.. baut_i.n,sul tt-ity„,--.
