Randal writes from Corner Brook, Newfoundland: “HOW SHOULD I INSULATE AND VENTILATE MY ATTIC IN AN OLD HOUSE?
There are some basic options to consider: 1) Add PINK batts or PROPINK® loosefill insulation over the top of the existing insulation, without moving what’s already there. Add Raft-R-Mate® attic vents in between the roof rafters to promote air circulation from the soffits to the top of the attic. They create an air space for ventilation and help prevent packing insulation in those critical areas. The batts can be installed overtop and should cover across the roof joists. The PROPINK® loosefill insulation is installed by a contractor. Since both types of insulation are light in weight, you can achieve high R-values, provided you have space in the attic. 2) Change the roof by having the old roof system removed and have a raised heel truss roof installed. It provides space for higher insulation values. This option is an expensive renovation project. 3) Look for air leakage in half story, knee wall areas. Old houses often have limited space to add insulation. However, they are also leaky. K
