The gauge of the effectiveness of any insulation is its R-value. Efficiency is made to stop the flow of heat. The more heat the insulation stops, the larger the R-value of this insulation.
When compared to fibreglass batt insulation, spray foam insulation features a higher R-value in a given width. In other words, 2 inches of spray foam may insulate your top better than 2 inches of fibreglass batts.
Cellulose complete, sometimes blown-in or used yourself, also has a higher R-value than fibreglass batts at-the same depth. But, again, the R-value of spray foam insulation is practically twice as large as cellulose complete insulation of the same width.
As essential as R-value is in how well insulation works, it is perhaps not the only thing to consider when selecting the most effective roof insulation. Moisture may cause both fibreglass batts and cellulose fill to get rid of R-value. Also slight moisture, that you just cant see or feel, may reduce the R-value of fibreglass batts.
Neither fibreglass batts or cellulose fill insulation may close every difference in your roof. Heat may move across the open spaces and this reduces the R-value of the efficiency, even though R-values detailed for fibreglass or cellulose don't take this into consideration. Put simply, the actual R-value of mounted fibreglass batt or cellulose fill roof insulation is leaner compared to the detailed R-value.

Spray foam insulation is not afflicted with moisture. In fact, it may stop slight leaks since, when it's used, spray foam insulation spreads to close your top and fill every gap. Contaminants and other airborne irritants that may get through the spaces left by batts and load are kept out by spray foam insulation.
Perhaps most useful of all, insulating your ceiling with spray foam insulation costs in regards to the sam-e as other insulations.
