AIR SEALING Air Sealing is a technique applied to your home using foams and insulations to block all areas of air infiltration and escape. The goal of air sealing is to keep the air your heating and ac systems are creating encapsulated within the walls of your home. You should not have to pay hard-earned money to heat or cool the great outdoors! Global Warming is doing that all by itself! These are techniques and theories that are typically applied to your: Attic Basement Crawlspace Windows Doors As well as the passages used within your walls to pass electrical, HVAC and plumbing from one floor to another. Also, as your home ages, the construction materials used to build your home shrink in size – typically wherever sheetrock meets the wood frame. These materials shrink in different directions, creating a gap between them. This allows the cold or warm air from your basement / crawlspace or attic to pass into your living spaces. Air sealing prevents this from happening. People have been misled into thinking that insulation is the answer to your energy conservation needs. In fact, if you don’t stop air movement, insulation is very ineffective. Air passes through insulation. Just like water, air always finds a way. By air sealing, you stop this process. HOW DOES IT WORK? We depressurize your home using high capacity blower fans and then take measurements of the amount of air leaving your home through this blower. This tells us how much air sealing is needed to be applied to your home to allow the proper amount of infiltration so you can still breathe with your doors closed and also to allow for the correct amount of makeup combustion air for your furnace, stove, water heater or any open-flame appliance to function properly.
