Pump insulation into roof.

The insulating effect of cellulose fibre ceiling insulation is a result of the transference of heat being retarded by the many air cells within the fibres when its pumped in its fluffed slightly so that its also got air locks between the fibres. No other product can provide the same insulation values in an existing cavity be it stud wall or weatherboard insulation brick veneer or even double brick. This is a professionally installed product used in limited circumstances usually when the attic will be converted to living space and you want to insulate between the roof rafters.

Ecofoam pump in foam wall insulation provides existing homes with the best possible r values in their existing cavity walls without having to remove the wall linings. Very similar to expanding builders foam in nature this form of insulation is again pumped into a cavity via a pressurised pumping system but unlike the below method the holes required to pump into the cavity can be much smaller making it a much better solution for properties constructed from engineered bricks as the required holes can be drilled in the mortar joints and those with smaller and narrower cavities such as new builds with existing sheet insulation.

I backfilled up to the roof put the foam on 18 letting it overhang and put 18 of soil on top of that. When hvac equipment is in the attic insulation and an air barrier at the roof line brings that equipment within the conditioned enclosure envelope thereby allowing it to operate in more favorable temperature and humidity conditions without air leakage and heat loss gain directly to the exterior. Most crews are very experienced in making the proper hole or entryway into the wall and have specialized hoses machines pumps and material in order to get the job done efficiently and effectively. Even the handiest of handymen will need to hire a trained insulation contractor for this kind of task.
