PH Airseal Becomes Champion Sponsor of the Accelerator

We’re happy to announce that PH Airseal has joined as the latest Champion Sponsor of Passive House Accelerator. The firm is based in northern New Jersey and specializes in using AeroBarrier technology in commercial, single-family, and multifamily buildings. The AeroBarrier air sealing system fortifies existing building envelopes and can be used to air seal down to the lowest ACH50 or CFM.

AeroBarrier technology has helped many projects seeking Passive House certification cross the finish line with its unique approach to sealing building envelopes by pressurizing the conditioned space, and then aerosolizing the non-toxic and Green Gold Guard Certified AeroBarrier sealant. Pressurization pushes the sealant into even the smallest nooks and crannies, sealing them off and creating air a more complete air barrier. While this is happening, technicians monitor the air leakage figures in real time. Once the target ACH50 or CFM is achieved, the team stops spraying the sealant, and then conducts a final blower door test to ensure they’ve reached the desired goal. The entire process can be replicated quickly, allowing the team to service multiple units in one visit. In most cases, they can seal between 10,000-20,000 ft2 of conditioned space per day.

PH Airseal was founded by Lawrence Linder, a Passive House certified tradesperson. Like his father and grandfather, Lawrence has worked as a general contractor in New Jersey throughout his career. In recent years, he has become increasingly interested in using technology and more advanced building science to create healthy, sustainable, and energy efficient renovations and additions. Through his work as a GC on numerous high-performance retrofits, he gained a greater appreciation of the importance of air sealing and AeroBarrier technology. In 2021, he founded PH Airseal with the goal of becoming the air sealing standard within the multifamily construction industry throughout the New York metropolitan area.

“Air sealing is integral to any Passive House project and we’re really excited to have PH Airseal on board as a Champion Sponsor,” said Michael Ingui, founder of Passive House Accelerator. “This is a valuable service for retrofits and I’m sure our community is going to enjoy learning more about the technology.”

“I’m really excited to share the benefits of AeroBarrier technology with the Passive House Accelerator community,” said Linder. “It’s going to really great to work with others who share such a strong commitment to building science and energy efficiency.”

“PH Airseal and Passive House Accelerator share strategic visions about the future of building, and I think people from the Passive House community and beyond might be surprised to learn how this technology can be applied to their retrofits and new builds,” said Passive House Accelerator Director Zack Semke.
