Mr. Omar had ice dam problems on his roof in winter. He also had problems with condensation on the ceiling and water droplets were forming.
Ice dams form when there are air leaks. The heated air quickly escapes into the attic and melts the snow on the roof. Water flowing over the roof turns to ice when it reaches the colder end of the roof. From there, huge icicles get formed.
Mr. Omar contacted Systèmes Éconergie to re-insulate his attic and solve the problems he was having.
The solution was to remove the wool to seal all air leaks on the attic floor like seams and holes to prevent the heated air from escaping quickly. Put boxes on recessed lights and seal them. Clear the soffits and install vents throughout the soffits to allow air circulation in the attic. Insulate the chimney, and then blow a little more than 16 in. of cellulose fibers to achieve an R-60 value.
Overview of the attic before work
1- There was only about 10” and less insulation in the attic.
Ice and icicle dam problem
This problem is caused by air leaks in the attic.
Condensation on a bedroom ceiling
The high humidity in the attic went through the holes and joints and caused this condensation.
Recessed lights are sources of air leakage
So we had to cover them and seal them.
Installation of vents throughout the soffits to ventilate the attic
. We also seal air leaks on the attic floor with our expanded polyurethane foam.
Work Done
Overview of the attic once well insulated with 16 in. of cellulose fibers.
