Cellulose Answer Man: Your Source For Information
I am a contractor working with cellulose to put into ceilings for builders in Australia. We have currently been questioned on the issue of the weight limitations for dry cellulose in ceilings (putting excessive pressure on plasterboard ceiling sheets) as compared to fibreglass batts. We would typically install R4.0 – R6.0 into new build projects which we would estimate somewhere between 4kg and 6kg per m2. While the same in fibreglass batts is estimated at only 2kg/m2.
Would you have any information or reference material that would assist us in determining appropriate weight limitations for cellulose installed in ceilings? I realize this may vary depending on how the ceiling has been constructed – however at this point we would be grateful for any information that may be able to assist us to use as a reference for supporting the use of cellulose insulation into ceilings.
Regards
