More than 90 percent of homes in North America lack adequate attic insulation and house insulation. Many homes in Canada lack adequate insulation, costing homeowners more money on energy bills to keep their houses warmer in the winter and cooler in the summer. With proper insulation, you can save money and be more efficient with your energy — and you can start by properly insulating your attic.
Things to Remember Before Starting
Always ensure that your installation is as clear and accessible as possible. You’ll need to be able to move around easily and access all required areas. You’ll also need something sturdy to walk/stand on such as a plank or sheet of plywood.
You’ll need some basic tools to help complete your project. Having a hammer, putty knife, caulking gun, tape measure, straight edge, utility knife, a lightweight stapler and a pole or rake (for hard to reach places) will help make this job a lot easier.
Lastly, remember that when you open a package of batting, it will expand significantly, so try not to open it outside of your project area.
For an uninsulated attic, it’s important to install a vapour barrier on the interior side of your roof before filling it with insulation.
When installing your batts, make sure to fit them tightly end-to-end as gaps in the insulation can greatly reduce your R-value. Make sure you don’t block any ventilation areas.
For electrical areas, slide the batts under the wires wherever possible, keeping it away from vents, exhaust fans, chimneys and any other heat-emitting objects and light fixtures. For exact information, consult your local building codes.
