What Makes Good Insulation?
Apr 03, 2009Checking your home’s insulation is one of the fastest and most cost effective ways to use a whole-house approach to reduce energy waste and make the most of your energy dollars.
There are several factors to consider when evaluating your insulation options:
- Thermal Performance
- R-value per Inch and Weight Limits
- Air Infiltration
- Cathedral Ceiling Ventilation
- Fire Resistance
- Health and Safety
- Environmental Contribution
- Effects of Moisture
- Acoustical Performance
R-Value R-value means the resistance to heat flow. The higher the R, the better the insulating power. The U.S. Department of Energy has recommendations for ranges of R-values based on local heating and cooling costs and climate conditions for the area you live in.
Noise Control The Owens Corning Noise Control Solutions reduce the levels of airborne noises transmitted through wall, ceilings and floors. Go to the U.S. Department of Energy for tips on sealing air leaks.
Air Penetration Air leaking into your home will allow hot air to enter in the summer and cold air to enter in the winter. Be sure to caulk, seal and weatherstrip all seams, cracks and openings to the outside.
Ventilation In order for your home to keep its climate controlled, it must have proper ventilation. Proper ventilation promotes positive air flow which allows the house to breathe and helps prevent moisture buildup.
Moisture Control Many of the typical household activities produce moisture in the home including washing, showers and cooking. Vapor retarders help control the amount of moisture passing through insulation and collecting inside exterior walls, ceilings and floors.
