The standard gauge of the efficiency of any insulation is its R-value. Insulation is created to stop the circulation of heat. The more heat the insulation stops, the greater the R-value of that insulation.
When compared to fiberglass batt insulation, spray foam insulation has a greater R-value at a provided density. Simply put, 2 inches of spray foam will insulate your roofing system much better than 2 inches of fibreglass batts.
Cellulose fill, either blown-in or used by hand, likewise has a greater R-value than fibreglass batts at the exact same density. Once again, the R-value of spray foam insulation is practically two times as high as cellulose fill insulation of the very same density.
As crucial as R-value remains in how well insulation works, it is not the only thing to think about when selecting the very best roofing system insulation. Wetness will trigger both fibreglass batts and cellulose fill to lose R-value. Even minor wetness, that you can’t feel or see, can minimize the R-value of fibreglass batts.
Neither fibreglass batts or cellulose fill insulation can seal every space in your roofing. Heat can travel through the open spaces and this lowers the R-value of the insulation, although the R-values noted for fibreglass or cellulose do not take this into factor to consider. Simply put, the real R-value of set up fibreglass batt or cellulose fill roofing insulation is lower than the noted R-value.
Spray foam insulation is not impacted by wetness. It can stop small leakages due to the fact that, when it is used, spray foam insulation spreads out to fill every space and seal your roofing system. Contaminants and other air-borne irritants that may survive the spaces left by batts and fill are stayed out by spray foam insulation.
Possibly most importantly, insulating your roofing with spray foam insulation costs about the like other insulations.
