What is the R-value of Enercept panels?
There are three methods of heat transfer – convection, conduction and radiation. R-value is the measure of resistance to heat loss by conduction only. The most important factor in thermal efficiency is the continuity of the insulation. The Enercept system results in a solid envelope of rigid foam insulation. Therefore, an Enercept structure has the ability to resist heat transfer by conduction and convection (air movement). It is resonable to assume that a conventional home would require an R-40 wall and an R-60 roof to compete with a 6 inch Enercept wall (R-24) and an 8 inch Enercept roof (R-32).
