You may not be aware o f it, but there's a good chance "dampness d em o n s" are on the loose in your ho m e, doing th e ir worst to cause damage and discomfort. T ellta le signs that dampness de mons are around are fogged mirrors and condensation o f m oisture on walls and elsewhere in your b ath room after use o f shower or tub fa cilities. But far more worrisome ef fects o f the demons in the bathroom are peeling paint or wall covering, rusting o f fixtures or cabinets, fo r m ation o f m ildew and warping o f doors. Also, the demons may cause paint to peel around the bathroom window outside the house and wet, stained, molded or rotted areas in in sulatio n or boards in the attic above the bathroom. The demons are created through the normal use of tub or shower fa cilities which puts an excessive amount o f moisture in the air. Use o f these facilities also results in an increase in water vap o r pressure and it ’s this pressure which forces the water droplets through walls, ceilings, cracks and other openings, where they can do their damage. Recent tests done at Texas A & M University under the sponsorship of the H o m e V e n tila tin g In stitu te ( H V I) , clearly show that excessive moisture and water pressure in the b ath ro o m can be controlled w ith proper ventilation. In an unventil ated b ath ro o m , the tests showed, the relative humidity (percentage of moisture in the air compared to the m oisture the a ir could hold at the same tem perature) reached 99 per cent during the use o f the shower and remained at 98 per cent for 25 minutes thereafter. By contrast, rel ative hum idity in a bathroom with an exhaust fan providing eight air changes an hour (as specified by the U .S . D epartm ent o f Housing and H V I standards) in operation peaked at 97 per cent, fell to 84 per cent ten minutes after the shower, and to 79 per cent, or near the starting point, 25 minutes after the shower. W h ile expelling dampness de mons is one o f the primary advan tages o f proper bathroom ventila tion, it is not the only one. Ventilat ing fans also help control bathroom tem peratures and clear the a ir o f odors, vapors which might be harm- The best way to combat dampness demons is to get rid o f them before they can do damage, and the most Do walla, atapa, baaamanta, foundation«, landscaping, ate.

For a re lativ ely sm all expense, bathroom ventilation offers protec tion, minimizes the need for clean ing, and enhances your com fort. I f your bathroom is unventilated, you should consider rectifying the situa tion. I f i t ’s ventilated, you might want to determine if the ventilation is sufficient.

A light-col ored ro o f, for example, attracts the eye and directs vision upwards. Used on a low house or unusually small roof, a light-colored roof will provide added dimension. A dark colored roof can be used for the op posite effect— making an unusually steep roof seem less towering. •Another design element in roof ing is dimension. Three-dimensional asphalt shingles add depth creating bold shadowlines. •In s te a d o f using contrasting colors, consider earth tone shades fo r blending a home w ith its sur roundings. The muted shades o f beiges, buffs, and browns, can also be used to coordinate the roof with masonry walls.

Roof color, texture provide decoration I f color and texture play such a vital role in the exterior appearance o f a home, why should the ro o f re main dull and lifeless? It shouldn’t. R oofing manufacturers have in troduced new products in recent years that offer greater flexibility in design. T h ro u g h the use o f color and texture, it’s now possible for the homeowner to start exterior deco rating right from the top— with the roof. Just as color and texture can en hance a ro o fs design, the improper use o f color can detract fro m a home's visual appeal. •Although siding and trim colors can be changed easily and with some regularity, you can expect to “ live with” your roof for many years— so select its color carefully. Do not use more than three different colors for siding, trim and the roof.

SPRING Pull shades on heat loss When it comes to rating the worst squanderers o f home energy, w in dows rank second only to an uninsu lated a ttic , according to the U .S . Department o f Energy. In winter, windows are especially energy-wasteful. They are responsi ble fo r as much as 35 per cent o f heat loss in a typical house. T h a t’s because window glass is a conductor o f heat. In fact, 3 to 4 times more costly furnace-generated heat is lost through the window than through the sash around it. In a study conducted at the Illin ois In s titu te o f Tech n olo gy, re searchers tested out standard w in dow shades that retail for less than $6 each. Their findings: shades keep in 24 to 31 per cent of the heat that normally escapes through windows. H e re ’s how . W hen shades are drawn, heat “ bounces” back like a basketball o ff a backboard. That is .. wilt give away a STORM DOOR why the W indow Shade M an u fa c turers Association suggests that when it is most cold outside— in the evening, at n ig h t, and during the early m o rn in g — pull your shades down to the sill. Be sure there is very little space between the vertical edges o f the shade and the window frame. This will block the escape of in te rio r heat. D u rin g the sunny hours, raise the shades and let the sun warm up the inside. with each order of STORM WINDOWS which totals ’900°° or more! DESIGNERS OF BEAUTIFUL KITCHENS AND BATHS The Illin o is Tech findings are good news during this high-cost fuel era. Less heat loss means less fuel waste and lower fuel bills. The re searchers estimate that proper w in dow shade use can chop as much as 8 cents o ff each heating dollar for a typical home in a moderate climate. Dollar-for-dollar, window shades are the homeowners best investment in fighting the high cost o f keeping warm during the cold, cold months o f winter.
