The basic measure of the efficiency of any insulation is its R-value. Warmth is made to stop the flow of heat. The more warmth the insulation stops, the larger the R-value of the insulation.
Spray foam insulation includes a higher R-value at a given depth, when compared to fibreglass batt insulation. In other words, 2 inches of spray foam may insulate your top better than 2 inches of fibreglass batts.
Cellulose fill, either blown-in or applied manually, also has a higher R-value than fibreglass batts in the sam-e width. But, again, the R-value of spray foam insulation is practically twice as large as cellulose fill insulation of-the same thickness.
As important as R-value is in how effectively insulation works, it's maybe not the only thing to consider when selecting the best roof insulation. Water can cause both cellulose and fibreglass batts fill to reduce R-value. Even slight moisture, that you cant see or feel, can decrease the R-value of fibreglass batts.

Neither fibreglass batts or cellulose fill efficiency can seal every gap in your roof. Heat can go through the open gaps and this reduces the R-value of the insulation, even though the R-values listed for fibreglass o-r cellulose don't take this under consideration. Put simply, the actual R-value of mounted fibreglass batt or cellulose fill ceiling insulation is leaner compared to listed R-value.
Spray foam insulation is not affected by water. In reality, it may end small leaks because, when it is employed, spray foam insulation spreads to fill every space and close your roof. Toxins and other airborne irritants that might cope with the gaps left by batts and fill are held out by spray foam insulation.
