How It Works
Gain Control of Your Environment
Air Sealing Done Right
AeroBarrier is the only method to reach any level of air tightness, the first time, every time.
We connect our patented technology to your home via a modified blower to pressurize and distribute the sealing formula.
The pressure carries our non-toxic, water-based formula throughout the home and effectively seals any leak by using the very air that is leaking out of the home, thereby finding any leak point; visible or not.
Have peace of mind monitoring the seal and seeing real-time result. You’ll even get a certificate of completion showing the before and after results.
How It Works
Seal the Gap
Our air sealing system seals all building envelope leaks up to ½”, and as small as a human hair.
Waterborne Acrylic Seal
GreenGuard Gold certified, the sealant is self-guided to the edges of leaks creating a seal.
Using a standard, single-point blower door test, our software measures the leakage in real time.
Real-time measurements enable you to dial in specific requirements and guarantee the results.
WE GUARANTEE AIR SEALING RESULTS IN 4 EASY STEPS
LEAKY HOMES ARE INEFFICIENT, UNCOMFORTABLE & UNHEALTHY
Air sealing is vital to an efficient, durable, healthy home.
It is one of the most important energy-efficiency measures. Air leakage, or infiltration, occurs when outside air enters a house uncontrollably through cracks, gaps, and openings. Homes with higher air leakage are significantly less energy-efficient than well-sealed homes. They also require larger HVAC systems to keep the home comfortable. These larger systems must run more frequently to keep up with the temperature changes as the outside air leaks into the house.
The airtightness issue goes beyond how well a building’s HVAC system performs. Uncontrolled air leakage can also provide a vehicle for unwanted moisture to enter a building, which can become the reason for a building to fail, leading to costly building repairs. Because moisture is transferred predominantly by air currents — accounting for up to 98% of all water vapor movement in buildings — air sealing your home is essential. Leaky houses also allow dust, allergens, pollutants and other airborne particulates to enter the home, leading to poor indoor air quality.
Reducing the amount of air that leaks in and out of your home is a cost-effective way to cut heating and cooling costs, improve durability, increase overall comfort, and create a healthier indoor environment.
Why Does Air Leakage Matter?
1. Is typically the largest driver of energy use in the home, comprising 30% – 70% of energy wasted on heating and cooling
2. It is usually the biggest contributing factor for drafts, hot/cold spots, and other comfort issues in a home
3. Often the largest contributor to moisture problems, especially mold and mildew
Addressing the Major Risks of Building
The control of heat flow in buildings requires insulation layers installed properly that are comprised of few thermal bridges, an effective air barrier system, good control of solar radiation, and management of interior heat generation.
Different than bulk water control, a vapor control addresses the moisture that travels via air and is unseen to the naked eye. Once inside a wall cavity, the vapor will go through convective loops in which it can reach dew point and turn from vapor to liquid. This is often seen later as condensation or damp insulation fibers.
Air Flow Control
In order for air to flow into, out of, or within a building, two requirements must be met: a hole or path must exist for the air to flow through and there must be a driving force. Air flows within buildings are either controlled or uncontrolled. In either case, the actual flow of air is determined by several factors, including hole size, resistance to flow, and pressure effects. Uncontrolled air flow can lead to comfort, indoor air quality and energy efficiency concerns.
Bulk Moisture Control
Bulk moisture movement (or liquid flow) has the potential to be the most damaging moisture transport mechanism confronted by a building. Typically thought of as rain or snow, bulk moisture movement also includes flowing groundwater. This can typically be addressed by proper land grade, redirection of water via gutters, downspouts, etc.
Provide a True R-Value
Outdoor temperatures, humidity, and air flow will break down the insulation around your home over time. Even worse, brand new insulation will not perform as it was designed if installed in an environment with air leakage which compromises its integrity. Less air leakage means there is less thermal impact the insulation must combat.
A study by the Fraunhofer Institute for Building Physics, in Stuttgart, showed that a leaky enclosure can decrease the insulation’s effectiveness by a factor of 4.8 – making a 500 sf leaky building require the same amount of heating as a 2,400 sf airtight building.
What size hole will AeroBarrier seal? AeroBarrier seals holes as large as 1/2" and as tiny as a human hair. Aerosol sealing is extremely effective at sealing narrow gaps and extremely small holes that are typically not cost effective or are missed during manual sealing.
Is it safe to breathe the sealant during application? No. During application, if a technician must eneter the space while being sealed, they wear personal protective equipment (PPE). After the sealing is complete, the area is safe to enter without protective gear within 20-30 minutes.
How long does it take to apply AeroBarrier? Application time depends on what the target ACH is for the house. Typical applications take between 90-120 minutes.
What surfaces need to be protected? 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 do not need to be covered. All designed openings, such as ducts, vents, electrical and plumbing penetrations, need to be covered prior to sealing. All finished horizontal surfaces need to be covered.
Can sealing be performed in cold weather? Although the sealing equipment can heat the air as it seals, there are practical limits to aerosol sealing when it comes to weather conditions. Ideal outdoor temperature is 40 degrees F or higher. Sealing can be done when the temperature is below 40 degrees F, but additional steps may be required.
What is the sealant made of? The AeroBarrier X1 sealant is a waterborne acrylic. The sealant is GreenGuard Gold certified and has been tested according to various ASTM standards and NFPA 285, for fire spread, smoke production, adhesion, anti fungal properties, and tensile strength. The sealant is ultra-low VOC and has no off gassing.
How is the leakage measured? The AeroBarrier system uses a standard, single-point blower door test to measure envelope leakage throughout the process. The blower door is calibrated to meet ASTM Standard E779, E1554, CGSB-149.10-M86, EN 13829, ATTMA Technical Standard 1, NFPA 2001, RESNET and USACE.
How long after the sealing process can you work in the house? The space needs to be aired out for 30 minutes after sealing. This is done by opening windows and running the fan. Work in the space can continue as soon as the sealing equipment is removed.
How much will this tighten the house? Aerobarrier can meet whatever requirements the space is designed to handle. The AeroBarrier technology provides real-time air tightness readings allowing air tightness to be specified and achieved every time. AeroBarrier can seal houses just tight enough to meet any IECC code requirement or it can seal to levels below the Passive House standard of 0.6 ACH50.
When can it be applied? AeroBarrier can be applied at any time after the space can be pressurized. Different construction methods and climate zones will determine the proper time to apply AeroBarrier. Rough-in or early stages of drywall is the most economical for application but it can be applied to completely finished spaces.
