A tighter built home means less outside air infiltrating in the home, which in turn means less oxygen to use for combustion within the furnace. As the furnace burns fuel and oxygen for combustion, it "eats up" the nearby air, which has to be "made up" with fresh air. If air cannot type in the home as quickly anymore, this could cause serious issues. As the surrounding air can be used for combustion, and not substituted for fresh air, a bad pressure in the space can take place. This could create combustion trouble for the furnace, plus consume fresh air for any person inside home. Expensive cosmetics can lead you to petroleum-based ingredients and also other synthetic materials who have questionable safety testing records. Why not use safe, skin oils in your beauty routine instead? When you know an ingredient is healthy to consume, it is certain it really is safe to use on the skin, your own body's largest organ.
