Removing unnecessary and somewhat misogynistic caveat

| Jan 21, 2023 at 9:51 | comment | added | Solar Mike | "we added..." Who did the work? What insulation was put below the floors? In the walls? in the roof? I there vapor barrier? Where is the dew point in the wall? Our house design had 12" or 30cm of insulation and the heating needs are very low even when winter temperatures drop to -15 deg C. | |
| Jan 21, 2023 at 8:09 | comment | added | Harper - Reinstate Monica | I'd be interested in how the ducting was done. The furnace needs to push A LOT of air into those new rooms... is it sufficiently sized for both the existing house and the addition? Did they run new ducts all the way from the furnace or just extend duct sections that were never intended to heat that much space? Are the ducts above the insulation (if so, when the attic is cold, they are losing heat through the walls of the ducts). Maybe adding a mini-split heat pump would be a plan. More efficient than gas. | |

Buy a dozen and place them around the addition and original house, at people height, and record a week's worth of full 24 hour readings (via smart phone app). That will give you or a consultant actual data on temperatures in different locations through day and night. | |
| Jan 21, 2023 at 6:54 | comment | added | Armand | Rather than first trying different things, spending money each time, why not hire an independent heating consultant or contractor to do a proper analysis of the heat loss from each room, and the HVAC supply (heat input) to that room. It might be that your addition is less well insulated than your main house, but it might also be that the addition doesn't have enough heating supply or uninsulated HVAC ducts or something else. | |

| Jan 21, 2023 at 6:04 | comment | added | DIY75 | : If you just hang a pice of insulation in the middle of the room, it will do nothing ,same applies to you 7 inch gap, allowing the clod to go under....so go ahead insulate, the more the better. – | |
| Jan 21, 2023 at 5:10 | comment | added | Rohit Gupta | I am sure that the insulation has some effect. But it's more likely to be the HVAC, especially if there is no sensor for the thermostat in the addition. That being the case, you will never get the mix of flows to different areas right. | |
