Gateway to the attic

If you’ve ever done a home renovation project, you know that the project you intend to complete isn’t the one you need to start with.

For example, my partner and I would like to add additional insulation to our attic, so we can make sure we’re using as little energy as possible to heat our home. The attic currently sports a messy mix of fibreglass batts and cellulose. According to our energy audit the level of insulation there only amounts to R 19.9 (R level is a measure of insulation value), whereas the EcoEnergy program recommends R 50.

That project will involve us calling in some help in sealing tops of walls with foam boxes and blowing in more cellulose insulation. But first, before we can do any of that, we have to replace the bathroom vent, and make sure it’s vented it outside. You see, the existing bathroom vent, which is mounted over the bathroom in the attic, isn’t well sealed, and it wasn’t properly vented either, so it spewed warm, moist air into the attic. Yesterday a roofer came by to install a roof vent for the bathroom fan. Excited by the upgrade, my partner decided we should connect our existing bath fan to the roof vent right away. So off to the home centre we went. Half an hour later we had all the insulated ducting, tape and fittings to do the job, and thanks to my partner’s handiwork, the fan is now vented outdoors.
