Insulation
by JimNavary
Insulation
The primary areas in your home to insulate are the attic, walls and floors. To accomplish the project efficiently, here are a few things you should know:
* Does your home require additional insulation material? Generally, if you have less than three inches of insulation in the attic, you should probably add extra insulation to achieve the proper levels. If none exists in the walls and/or floors, insulation is highly recommended.
* You will need to determine whether you want to complete the insulation work yourself or to turn over the job to a contractor instead. Keep in mind that some insulation jobs are considerably harder than other household projects.
* If you would rather have a contractor handle the job, be sure to get several bids. Only use a bonded and properly certified contractor.
* If you tackle the job yourself, be sure to follow installation instructions precisely and don't forget to follow pertinent safety precautions.
* When buying insulation, note the R-value. This indicates the effectiveness of insulation. The larger the number the more effective the insulation.
* Decide what type of insulation you need. There are many different types of insulation products available including fiberglass, cellulose, mineral wool/rock wool, rigid insulation and sprayed foam. The choice of material will mainly depend on the section of the house you are insulating. You can ask a knowledgeable salesperson 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 indicates the window's insulating ability. The lower the value, the better the window is at preventing the transfer of heat. The U-value of a window is based on the number of glass layers, the amount of of air space between the panes or layers and the materials used in the window frame. A few tips include:
* Inspect windows for broken glass, damaged frames and seals, damaged wood, loose putty, defective sashes, and drafts.
* For a quick but temporary fix before cold weather hits, you can buy storm-window kits made of plastic sheeting that you apply to the interior of your windows. These kits are usually available at most home improvement stores for $5 to $10 per window. They usually last from two to four years.
* You can diminish heat loss through windows by installing insulating curtains or drapes on the inside of the window. This will help reduce heat loss during cold weather and keep cool air in during the dog days of summer.
* In the winter tie back the curtains during hours of sunlight to allow natural heating, and, during the summer keep the windows covered or attach an ultraviolet film to reduce the sun's effect.
* During the warmer months, when possible, open several windows during nighttime and in the early hours of the morning when there is a gentle breeze. Opening a window on opposing sides of the house will improve air circulation and provide improved cooling.
Caulking & Weather-stripping
In addition to poor insulation, air leaks are amongst the major causes of energy waste in homes.
* Inspect your home for hidden air leaks by using a damp hand or candle flame to identify air movement. Shut all doors, windows and fireplace flues and shut down all ventilating fans to make any air leaks easier to locate.
* Caulk is best used on openings that are less than 1/4" wide. If possible, use caulks that will stay flexible over a long number of years. If it is not completely hidden, pick a colored caulk or one that can be painted.
* If there are sizeable cracks and missing pieces shielded from light and moisture, try expanding foam sealers to fill them. However, please use only products identified as safe for the environment.
* Backer rod or crack filler, is a elastic foam material sold in long coils, with a number of different diameters available. It can be useful in sealing larger gaps. It also can serve as a filler material in deep spaces that are to be finished with standard caulking.
* Place insulation behind electric outlets and wall switches - openings that are often unnoticed.
