Overview
If your home feels drafty in winter, stuffy in summer, or your HVAC system runs constantly without ever getting comfortable, the problem is hiding in your walls. Leaks in your home’s building envelope are the #1 source of energy waste for Kansas City homeowners. At Green Seal Energy, we solve this problem with AeroBarrier, a patented, computer-controlled aerosol sealing technology that pressurizes your home and seals leaks from the inside out. As an AeroBarrier-certified installer and Aerosel Authorized Dealer, we bring over 20 years of home performance expertise to every project. Unlike traditional manual sealing, which relies on a technician’s eye to find and patch visible gaps, AeroBarrier finds and seals 100% of leaks up to a half-inch, including those hidden behind drywall, under subfloors, and in rim joists where most energy loss occurs. The result is a measurably tighter, more comfortable, and dramatically more efficient home — with none of the guesswork.
Education
Envelope air sealing is the process of closing gaps, cracks, and penetrations in your home’s outer shell. The building envelope includes everything that separates indoor conditioned space from the outdoors: exterior walls, the roof, the foundation, windows, and doors. When these components aren’t fully sealed, conditioned air escapes and unconditioned outside air infiltrates, forcing your HVAC system to work much harder than necessary. AeroBarrier is an advanced, automated air sealing solution that represents a fundamental shift from manual methods. The process starts with a blower door test to measure your home’s baseline airtightness. Then, technicians set up the AeroBarrier system, which fills the sealed interior with a water-based, low-VOC sealant mist. Guided by onboard sensors, the mist is drawn precisely to each leak, building up particle by particle until the gap is fully sealed. Real-time monitoring shows the leakage rate dropping second by second until you hit your target. No demolition, no mess, and no missed spots.
We provide a Duct Leakage Test Report and Certificate showing duct leakage before and after sealing (see sample attached).
