In fact, loosely constructed houses often are difficult to keep comfortable, due to cold drafts, outside noise, and unwanted humidity. These can be minimized through caulking and sealing. House design and mechanical equipment selection affect the pressure differential across the building envelope. Benefits If properly sealed and ventilated, an air-tight house reduces energy costs and improves comfort. Preventing air leakage is a cost effective way to improve the quality of the homes you build, increase customer satisfaction, increase customer referrals, and increase sales.
Airtight construction is one of the most cost effective ways to reduce home energy costs.
Air leakage can account for 30-40 percent of home heat loss, Reducing this major source of heat loss is the first and most critical step in building an energy efficient house. In addition, performance of other energy efficiency measures, such as better insulated walls and high performance windows, is degraded when air leaks around or through them. Air sealing makes a tighter, quieter, more comfortable home. Better quality construction is the result of carefully sealing all joints and penetrations. This eliminates uncomfortable drafts, promotes more even heating and cooling, and reduces outside noise.
