Closed Cell Spray Foam The basic scale of the performance of any type of insulation is its R-value. Insulation is created to quit the flow of warm. Thegreater amount the insulation stops, the greater the R-value of that insulation. When compared to fibreglass batt insulation, spray foam insulation has a higher R-value at a given thickness. To put it simply, 2 inches of spray foam will insulate your roof covering much better than 2 inches of fibreglass batts. Cellulose fill, either blown-in or used by hand, also has a greater R-value than fibreglass batts at the exact same density. Yet, once more, the R-value of spray foam insulation is practically twice as high as cellulose fill insulation of the very same thickness. As vital as R-value remains in exactly how well insulation works, it is not the only point to take into consideration when selecting the very best roof insulation. Moisture will cause both fibreglass batts and also cellulose fill to shed R-value. Also minor wetness, that you can’t see or feel, can lower the R-value of fibreglass batts. Neither fibreglass batts or cellulose fill insulation can secure every void in your roof. Heat can go through the open voids and this decreases the R-value of the insulation, although the R-values detailed for fibreglass or cellulose do not take this into factor to consider. https://www.facebook.com/insulationtylertx/ Posted via https://local.google.com/place?id=1002703672292374879&use=posts&lpsid=4990169764323271202 From http://sprayfoamtylertxllc.blogspot.com/2020/02/closed-cell-spray-foam.html from https://sprayfoamtylertxllc.wordpress.com/2020/02/17/closed-cell-spray-foam/ from https://insulationsprayfoam0.blogspot.com/2020/02/closed-cell-spray-foam.html
