FAQ

AeroBarrier is an interior applied air sealing system that seals all building envelope leaks up to 1/2″. The waterborne acrylic sealant is applied by pressuring a targeted building area, then spraying the aerosolized sealant into the pressurized space. The sealant is self-guided to the edges of visible and invisible leaks creating a seal, not by packing the gap but by accumulating across the surface of leaks. Designed to deposit in leaks and not on vertical surfaces, the sealant is applied within 60-90 minutes and dries before system cleanup is complete, allowing construction to resume shortly after the process is complete with little to no impact on standard construction schedules. The system measures the envelope leakage in real-time, enabling the system to dial-in specific requirements for air leakage and guarantee the results.

The sealant is non-toxic and has been safely used in hospitals, surgery centers, schools, and government facilities all over the world. Additionally, the sealant has been tested by an independent lab and found to have extremely low concentrations of volatile organic compounds (VOC’s). The primary component has no OSHA maximum exposure limit.

Costs vary depending on the size of the building. We recommend getting a quote from a TJ Wies Sealing Solutions expert.

Independent government-sponsored studies have shown that sealing ductwork can save $850 per year! Energy savings can be difficult to predict. Many variables can contribute to energy savings, including the location and age of the home. An evaluation by an HVAC professional can better determine potential improvements.

A series of government reports have shown that air duct sealing can lead to up to $850 in energy savings per year. Some homeowners have saved up to 40% on their energy bill. Naturally, exact savings are difficult to precisely estimate since they depend on a multitude of variables such as your weather, house condition and design, your heating and air conditioning system, system usage – as well as other factors like energy prices.

No. During application, if a technician has to enter the space while it is being sealed, they wear personal protective equipment (PPE). After the sealing is complete, the area is safe to enter without protective gear within 20 to 30 minutes.

The AeroBarrier sealant is based on a waterborne acrylic that has been used as a fluid-applied permeable air barrier for many years. The sealant is GREENGUARD Gold certified and has been tested according to various ASTM standards and NFPA 285, for fire spread, smoke production, adhesion, antifungal properties, tensile strength, etc..

The sealant is low VOC and has no off-gassing

AeroBarrier may be applied at any time between rough-in and prior to occupancy. Although, the ideal time to apply AeroBarrier is rough-in or post-drywall. Other factors that affect installation are build process and climate zone.

The area needs to be aired out for 30 minutes after the sealing is complete. This is done by opening doors and windows while running the fan. But work can resume in the space as soon as the sealing equipment is removed and 30 min has passed.

Third-party lab testing reveals AeroBarrier withstands a simulated 50-year durability test, with little or no seal degradation. Click here to see the durability test results.

If AeroBarrier is applied at rough-in or right after drywall is installed, there is very minimal preparation required. Vertical surfaces like walls and windows require no covering. All designed openings, such as ducts, vents and plumbing, need to be covered prior to sealing. All finished horizontal surfaces need to be covered.

Ductwork runs through attics, crawlspaces, basements, garages, and walls. Leaking return air ducts pull in dust and other indoor air pollutants and sends them to the central heating and cooling system. From there they are sent to the living areas of your home.

The Aeroseal air duct sealing system can reduce the amount of leakage by as much as 90%, reducing dust and other indoor air pollutants from the conditioned air in your home.
