If the house is less than 5 years old, then maby, just maby it is a possibility, but it is so imagenary slim that I hardly belive that you can ever get it soo tight. I'm a electrisian in Denmark, and we have some of the tightest demands in the world about how sealed a new constructed house is build today, only Norway has better demands. If a house is energyneutral, you must have the plasticmembrane absolutely 100% airtight overall in the house, and then 50 cm insulation or about 20 inch n the ceeling, walls and floor. Futhermore inorder for the house to become "energy neutral" here, you must invest in solarcells or a windmill, and use a heatpump. Today's standard for a new house here is 30 cm insulation or about 12 inch of a goodgrade fiberglass insulation or flamingo. But the airtightness in the house must still be extreme good, since fiberglass itself insulate squat nada, but the air inside the insulation is what insulate. Seelings around windows, the hole up to the attic, the space between groundfloor and the firstfloor is often not insulated, and there is even more often no windbraker, so when it is windy, the wind sweeps in and cools down. I can tell you from personal experience. If you do renovate a bathroom or whatever, be extreme good at seeling that plastic so the room will become airtight, again, fiberglass insulation dont insulate, but the air inside it does, but when there is a air exchange, then the insulation is worth squad sh.. the possibility that you can overseal the house is impossible.
