How Do You Air Seal a House with an Aerobarrier?

Even recently constructed buildings and houses fall victim to leaky envelopes. Air infiltrates the tiniest gaps on the roof, subfloor, exterior doors, walls, and other areas. Air infiltration corresponds to increased reliance on heating and cooling equipment. Although there exist several methods of sealing house leaks, most of them are inefficiently performed. It takes a ton of effort to finish one job, yet the tightness standards aren’t usually met.

Aerobarrier offers by far the most comprehensive air sealing solution. The process is doubly efficient and exceeds the envelope sealing standards. Instead of a conventional manual application, Aerobarrier is applied in the interior to seal all building envelope leaks and gaps measuring up to half an inch. It’s a waterborne acrylic sealant which uses pressure and spraying method to cover unreachable parts of the building.

Sealing a house with Aerobarrier requires a pressurized space. The contractor creates the ideal pressurized room before spraying the sealant. Aerobarrier has a self-guiding property, so there’s no need to pack the gap with a standard sealant manually. Once it’s released into the pressurized indoor atmosphere, it finds its way to the edges of both visible and invisible leaks, where it creates the seal. The tiny particles accumulate across the surface of the gaps, eventually sealing them.

In most scenarios, Aerobarrier is applied from one up to three hours, depending on the size of the building and other external factors. The sealant dries before the completion of a building or house construction. Hence, it doesn’t disrupt or causes any delay on the schedule.

Local builders and contractors have nothing but praise for Aerobarrier, especially with the real-time measurement of envelope leaks. The system is designed to meet highly specific standards (requirements) for air leakage, which is why results are always guaranteed.

How Aerobarrier Works (Step-by-Step)

Step One – Prep

The first step consists of blocking (covering) all openings in the room that aren’t going to be sealed. Local contractors have their way of covering the openings, depending on what they think is the most efficient. The idea is to cover designed openings and finished horizontal surfaces before setting up the emitters for air sealing. After covering the openings, the equipment enters the room; it’s made up of the blower door, hoses, emitters, and the Aerobarrier device.

Step Two – Pressurize the Room

The only way to pressurize an interior space is to use a blower door. It is paired with a computer that controls the process. Without the computer, there’ no way to monitor temperature, humidity, and pressure. It also controls the sealant distribution. Pressurizing the room is a necessary step for Aerobarrier to work its magic. Without it, the sealant won’t work.

Step Three – Air Sealing

Aerobarrier represents the modern take on air sealing. Its significant advantage to conventional air sealing is that results are given in real-time. With the sophisticated technology, the contractor comes up with a highly specific level of airtightness. Results come in simultaneously, so it’s easy to adjust. Once air sealing is finished in a couple of hours, a blower door test is performed to verify the results. Part of the Aerobarrier service is printing out a certificate of completion which details pre and post leakage results.

Step Four – Clean Up

Cleanup follows right after the completion of air sealing with Aerobarrier. Unlike the usual method, cleaning up the area is manageable in under an hour. It means that other aspects of the construction resume in no time. The clean up includes removing the equipment, coverings, and tape. That’s about it – there are no visible debris or damaged parts.

Residential Application

Reduced air leakage in a residential setting corresponds to improved energy efficiency, increased durability of the housing components, plus you lessen mechanical loads. Yet arguably, the most important benefit is increased comfort. There’s a considerable improvement in indoor air quality inside the living space if the house has a tighter envelope.

Multi-Family Residences

Aerobarrier offers a practical solution against air leakage in multi-family and compartmentalized living spaces. Improved building envelope in these settings doesn’t only help save energy; it also prevents the likelihood of moisture penetration and stack effect. Preventing moisture from creeping in congested and tightly spaced living spaces controls the spread of smell, pest infestation, and buildup of mold. With a tighter envelope, occupants feel more comfortable.

Commercial Settings

Aerobarrier isn’t exclusive to residential properties – commercial buildings benefit from aerosol sealing, most notably in the aspect of energy efficiency. Sealing a commercial space using Aerobarrier reduces building leakage by up to 75%. It’s not limited to existing buildings as Aerobarrier is also feasible in new and retrofit projects. Compared to traditional air sealing, it offers minimal labor costs and cuts the application time in half.
