What You Should Know About R-Value
When you choose siding insulation, you should always consider the R-Value. What is R-Value? As it applies to insulation, R-Value is a measure of how well a layer of insulation resists the flow of heat in or out of a building. The heat flow is measured in heat flux units.
The higher the number, the higher the insulation value or R-value. For instance:
- Open-cell spray foam has an R-value of 3.7 units per inch.
- Closed-cell spray foam has an R-value as high as 6.5 units per inch.
- Cellulose has an R-value of 3.5 units per inch.
- Fiberglass has an R-value of 2.9 to 3.8 units per inch.
As you can see, spray foam insulation has a higher R-value than cellulose and fiberglass. It provides exceptional insulation for your home. However, cellulose and fiberglass still provide adequate insulation in your attic or walls. Keyprime Roofing can help you decide which insulation is best of your home based on all the factors of the installation.
