Insulation

Insulation

The essential areas in your home that should be well insulated are the floors, walls and attic. To do the job efficiently, here are a few things you should know:

* Does your home need additional insulation material? Generally, if your home has less than three or four inches of insulation in the attic, it would be a good idea add additional insulating material to achieve the proper levels. If none exists in the walls and/or floors, insulation is highly recommended.

* First, you will have to decide whether you want to complete the insulation project yourself or to hire a professional instead. Don't forget that some insulation work is quite a bit harder than other household projects.

* If you would prefer to have a contractor perform the work, make sure you get several bids. Only hire a bonded and properly licensed contractor.

* If you tackle the job as a DIY project, follow installation instructions precisely and follow pertinent safety precautions.

* When purchasing insulation, pay attention to the R-value. It shows the efficiency of insulation. The higher the number the higher efficiency of the insulation.

* Choose the type of insulating material you need. There are numerous insulation materials available including fiberglass, cellulose, mineral wool/rock wool, rigid insulation and sprayed foam. The choice of material will for the most part depend on the part of the home to be insulated. You can ask a knowledgeable salesperson to help determine the best insulation R-value and type of insulation for your project.

Windows

Rating windows insulation value is measured by the U-value. This number specifies the window's ability to insulate. The lower the U-value, the better the window is at stopping the transfer of heat. The U-value of a window is determined by such factors as the number of glass panes, the amount of of insulating space between the panes and the type of window frame. A few tips include:

* Inspect windows for broken glass, broken frames and seals, damaged wood, missing putty, poorly fitting sashes, and air leakage.

* For a quick but temporary fix before wintry weather arrives, you can buy storm-window kits constructed of plastic film that you tape to the inside of your windows. The kits are available at most hardware stores for $5 to $10 per window. They generally last from two to four years.

* You can cut down heat transfer through windows by mounting insulating curtains or drapes on the inside of the window. This will help reduce heat loss during cold weather and reduce radiant heat during heat waves.

* In the winter retract the curtains when the sun is shining to allow passive solar heating, and, during the summer block the sun with your curtains or attach an ultraviolet film to help keep the heat out.

* During the summer, when possible, open two or more windows during nighttime and in the early hours of the morning when there is a breeze. Opening a window on each side of your home will aid in air circulation and offer improved cooling.

Caulking & Weather-stripping

In addition to poor insulation, air leaks are among the major sources of energy waste in homes.

* Examine your house for concealed air leaks by using a moist hand or candle flame to discover air leaks. Shut all doors, windows and fireplace flues and switch off any ventilating fans to make the air leakage easier to locate.

* Caulking is best used on areas that are less than 1/4" wide. When available, use caulking that will remain pliable over a long period of years. If it is visible, select a colored caulk or one that will accept paint..

* If there are substantial gaps and voids shielded from light and water, try expanding foam sealers to plug them. However, please buy only products identified as safe for the environment.

* Crack filler or backer rod, is a flexible foam product available in long coils, with a number of different available diameters. It can be useful in sealing larger gaps. It also can be used as filler material in deep spaces that are to be sealed with ordinary caulking.

* Position insulating material behind electric outlets and wall switches - openings that are often unnoticed.
