Insulation R-values are the manner of measuring insulation ability to resist the flow of heat. Higher levels of insulation R-value means it has a higher capacity of effectiveness in resisting heat. When buying insulation for your home, more is not always better. Often it is more cost effective to buy better R-value insulation at a higher cost to save more on the overall purchase price of effective insulation. Here is more information to help you better understand insulation R-values.
- Most laboratory tests done regarding insulation R-values are set in an environment with zero air motion with a temperature of 70 degrees Fahrenheit.
- When it comes to basement insulation for a home, the usually required insulation R-value for effective resistance of heat is 12.
- Insulation R-values chosen for a home are based on the home’s average weather conditions, temperature, and climate.
- An inch of well-packed insulation is equally heat resistant to two and a half feet of concrete.
Here are the two top choices for insulation materials with their corresponding R-value requirements.
- Cellulose Insulation – Blown in cellulose insulation averages an R-value of 3.7 for every inch
- Fiberglass Insulation – Fiberglass insulation requires an R-value of 3.14 for every inch
Protect Your Home’s Insulation
Any insulation installation should be followed up with proper dry wall application or other protective measures. By protecting your insulation you’ll keep it from deteriorating. Unprotected insulation is susceptible to unnecessary moisture. Moisture can weight down your insulation, lower its R-value, and decrease its efficiency.
