The value in knowing R-Value

User Rating:  / 0
If you are in the midst of renovating or building your home, it is likely you have heard the term "R-Value" being thrown around. Understanding what it means and its importance is the real test. 
Measuring the ability to limit the heat flow transferred through insulation is known as R-Value, say specialists in this field. 
Augmenting the traditional insulation in walls and ceilings is not typically regarded by industry specialists as an effective short-term or long-term solution, since it does not offer air sealing capabilities the way modern alternatives do. 
Spray foam insulation, like that available from innovators Icynene, provides a consistent R-Value plus air seal in one step without the potential for sagging, settling or gaping that traditional insulation might. 
Adding further layers of insulation in a traditional environment just to increase R-Value eventually proves superfluous and ineffective with very little payback over the long-term. 
The United States Department of Energy says that compressed insulation will not provide its full R-Value. Moreover, the installed R-Value will differ from the insulation R-Value itself due to heat flow around the home making it imperative that the insulation is properly installed by a professional who knows their product and how they work.
Homeowners should stay ahead of the curve and understand what is right for their home to ensure its long-term sustainability. Further information on R-Values and air sealing can be found at
