Extra Attic Insulation Has Immediate Benefits

Over the last two days we added an extra R20 of insulation to our attic, bringing it up to a total of about R40. In the process we discovered that one area in the attic had been completely bare.

There have been immediate results. There used to be a temperature differential between the main floor and the top floor of 3-4C, and now it is only 1C. That makes for a huge difference, because while the basement and main floor use forced air, the upstairs has expensive electrical heat.

We've also noticed that the furnace is working much less, easily maintaining 20C with only a few minutes of heating every few hours.
