Heat transfers very quickly through the air to the ceiling drywall; air has a high thermal diffusivity value of 21.33 mm2/s. A few more points: while heat gain through ceilings can be significant, especially in a house that has very little ceiling insulation, two other sources of heat gain are often more significant: heat gain through windows and internal heat gains from lighting and other appliances (oven, kitchen range, refrigerator, TV, etc.). I stand by my statement. In a climate with no heating requirements, don’t use a large amount of insulation; Past the first couple of inches, it doesn’t really help you very much because it stores more heat. If you don't have ductwork that's in use year-round, you need to add dedicated ducting and air handling for the HRV….

Are your windows old and bad and do they receive a lot of direct sunlight? Could there be any internal gains you're unaware of or not considering?

If your attic just needs a top up for maximum efficiency, we’ll help you there as well. Find your zone on the map and then use the above insulation R-value chart to determine the level of insulation you need to properly insulate your attic, walls, floors and crawlspaces.

Enter your options and zip code above - then select "Update".
