Insulation
Insulation The essential areas in your home that should be well insulated are the walls, attic and floors. Here's what you'll need to know to get the job done: * Does your home need additional insulation material? Generally, if you have less than three inches of insulation in the attic, you would be well advised to add extra insulating material to achieve the correct levels. If you find that there is no insulation in the floors or walls, adding insulation is highly recommended. * First, you will have to determine whether you want to perform the insulation project yourself or to hire a professional instead. Don't forget that some insulation work is quite a bit harder than other home improvement projects. * If you would rather have a contractor perform the work, make sure you get several bids. Only employ a bonded and properly licensed contractor. * If you do the job yourself, be sure to follow installation instructions precisely and pay attention to proper safety precautions. * When purchasing insulating material, pay attention to the R-value. It specifies the efficiency of insulation. The larger the R-value the higher efficiency of the insulation. * Decide what type of insulation you require. There are many different types of insulation materials on the market including fiberglass, cellulose, mineral wool/rock wool, rigid insulation and sprayed foam. The choice of material will ultimately depend on the area of the house you are insulating. A knowledgeable salesperson should be able to help establish the best type of insulating material and R-value you need. Windows Rating windows insulation value is measured by the U-value. This number shows the window's ability to insulate. The lower the U-value, the better the window is at preventing the transmission of heat. The U-value of a window is determined by such factors as the number of glass layers, the thickness of air space between the layers and the type of window frame. A few tips include: * Inspect windows for cracks, damaged frames and seals, rotten wood, loose putty, poorly fitting sashes, and drafts. * For a quick but short-term fix before wintry weather hits, you can purchase storm-window kits constructed of plastic film that you attach to the inside of your windows. Insulating kits are usually available at most hardware stores for $5 to $10 per window. They typically last from one to three years. * You can diminish heat transfer through windows by installing insulated curtains or drapes on the inside of the window. This will help keep heat in during the winter and reduce radiant heat during the summer. * In the winter retract the curtains if the sun is out to allow natural heating, and, during the summer block the sun with your curtains or add an ultraviolet film to help keep the heat out. * During the summer, when possible, open a few windows during nighttime and early in the morning when there is a cool breeze. Opening a window on opposing sides of the house will help with the flow of air and provide better cooling. Caulking & Weather-stripping In addition to inadequate insulation, air leaks are among the major problems with energy loss in homes. * Inspect your home for hidden air leaks by using a damp hand or candle flame to detect air movement. Secure all doors, windows and fireplace flues and turn off all ventilating fans to make any air leakage easier to locate. * Caulk is best used on gaps that are smaller than 1/4" wide. When available, use caulks that will stay flexible over a long number of years. If it can be seen, select a tinted caulk or one that can be painted. * When there are sizeable gaps and holes shielded from sunlight and water, apply expanding foam sealant to plug them. However, please use only products listed as ozone safe. * Backer rod or crack filler, is a elastic foam material sold in long coils, with a variety of diameters available. It can be useful in sealing larger voids. It also can be used as filler material in deep spaces that are to be sealed with regular caulk. * Position insulating material behind electric outlets and switches - areas that are often overlooked.
