The essential measure of the effectiveness of any insulation is its R-value. Insulation is made to stop the flow of heat. The more heat the insulation stops, the bigger the R-value of that insulation.

When compared to fibreglass batt insulation, spray foam insulation has a higher R-value at a given depth. Put simply, 2 your roof will be insulated by inches of spray foam a lot better than 2 inches of fibreglass batts.

Cellulose fill, either blown-in or applied by hand, even offers an increased R-value than fibreglass batts at the same width. But, again, the R-value of spray foam insulation is almost doubly large as cellulose complete insulation of exactly the same depth.

As important as R-value is in how well insulation works, it's not the only factor whenever choosing the very best roof insulation. Moisture may cause both fibreglass batts and cellulose fill to lose R-value. Even minor moisture, that you cant see or feel, may reduce steadily the R-value of fibreglass batts.

Neither fibreglass batts or cellulose fill efficiency can seal every difference in your roof. Heat may move across the open gaps and this decreases the R-value of the insulation, although the R-values listed for fibreglass or cellulose don't take this into consideration. In other words, the specific R-value of mounted fibreglass batt or cellulose fill roof insulation is gloomier compared to the stated R-value.

Spray foam insulation isn't afflicted with water. In fact, minor leaks can be stopped by it since, when it's employed, spray foam insulation spreads to seal your top and fill every hole. Contaminants and other airborne irritants that may complete the spaces left by batts and load are kept out by spray foam insulation.

Perhaps on top of that, insulating your ceiling with spray foam insulation charges a comparable as other insulations.

The spray foam ceiling insulation authorities at Foam Comfort have the ability you need to get the most from your insulation. compare roofers jacksonville
