Airsealing Makes A Difference

How air sealing with Aeroseal Envelope works

(Before) Winter: Cold air comes into the building and hot air escapes. Summer: Cold air escapes and hot air enters.
(After) Winter: Cold air can’t penetrate the building and heated air stays inside. Summer: Hot air stays out and cold air stays in.

New Builds or Remodels

Why Air Sealing Technology Matters

Energy Efficiency

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.

Unmatched Energy Efficiency:
Aeroseal Envelope significantly reduces air leakage, resulting in lower energy consumption, reduced utility bills, and enhanced overall energy efficiency for the homeowner.

Superior Indoor Air Quality:
A well-sealed envelope ensures that pollutants, allergens, and dust are kept outside, contributing to healthier and more comfortable indoor environments for your clients.

Sustainability and Green Building:
With the growing emphasis on sustainable construction, Aeroseal Envelope allows you to elevate your custom homes’ eco-friendly features, appealing to environmentally-conscious clientele.

Enhanced Home Comfort:
By preventing drafts and cold spots, Aeroseal Envelope ensures consistent indoor temperatures and improved comfort for homeowners all year round.

Distinguished Reputation:
Adopting this cutting-edge technology sets you apart as an industry leader, showcasing your commitment to staying at the forefront of innovation in custom home building.

Versatile Applications

Single Family Homes

For residential applications, reduced building envelope leakage means increased durability, reduced mechanical loads, improved energy efficiency, and more economical renewable energy options. More importantly, a tighter building envelope can help increase the comfort and overall indoor air quality (IAQ) within the home, leading to a better living environment.

New Construction

In new construction or gut renovation applications, the Aeroseal Envelope air sealing system will accurately seal at any stage from rough-in to move-in. Depending on the climate zone and environment, a builder or homeowner may prefer to have their air barrier post drywall as opposed to pre-drywall, or vice versa.

Multi Family Buildings

The Aeroseal Envelope air sealing system is the perfect solution for compartmentalization and multi-family applications. Reducing the amount of air leakage in multi-family buildings also lowers the amount of moisture traveling in the air, decreasing the likelihood of mold and water damage. The end result is potential Title 24 savings.

Frequently Asked Questions

What is a passive house?2023-09-13T17:56:31-07:00

A passive home is one that requires minimal heating and cooling. In essence these homes are very energy efficient reducing its ecological footprint. The “Passivhaus” concept was developed in Germany in the 1980’s. It includes superior insulation, airtight construction, high performance windows, ventilation with heat recovery, elimination of thermal bridges or paths where heat can flow through the building, utilization of passive solar heating, energy efficient appliances and lighting, and monitoring that the building meets a standard. As a result, Passive Houses typically use up to 90% less energy for heating and cooling compared to conventional buildings.

What is ACH50?2023-09-13T15:13:51-07:00

ACH50 stands for air changes per hour at 50 pascals of negative pressure. Pascals are a standard unit measure of pressure comparable to pounds per square inch (PSI).  ACH is a calculation of the cubic volume of space divided by air volume moving in and out per hour. For ACH50, a blower is used to measure the infiltration of outdoor air into a structure to compare the relative “tightness” of that structure. The measurement used is 50 pascals of negative pressure in reference to outside pressure. A higher number means that more air can infiltrate the structure (loose), whereas a low number means less air can infiltrate (tight). This number doesn’t reflect air moving in and out of the space when it isn’t pressurized.

How does Aeroseal Envelope work?2023-09-13T18:00:18-07:00

Aeroseal Envelope is an interior applied air sealing system that seals building envelope leaks up to 1/2″. The waterborne sealant is aerosolized and injected into a pressurized home. The sealant is self-guided to the edges of visible and invisible leaks to create a seal by accumulating across the leaking surface. The sealant is applied within 60-90 minutes and dries quickly before system cleanup is complete. This ensures construction can resume shortly after the process is complete with little to no impact on standard construction schedules. The Aeroseal Envelope system measures envelope leakage in real-time, enabling the system to dial in specific air leakage requirements with precision and guarantee the results.

What size of leaks can this product effectively seal?2023-09-13T17:24:53-07:00

Aeroseal Envelope seals holes as large as 1/2”, and as tiny as human hair. Aerosol sealing is extremely effective at sealing narrow gaps and extremely small holes that are typically not cost-effective to seal manually, or that are missed using manual sealing techniques.

To what extent can it create a secure seal, and is this sealing method safe?2023-09-13T17:25:52-07:00

Aeroseal Envelope has sealed houses to as low as 0.19 ACH50. But the value is in the system’s ability to allow builders to seal a home as tight as it is designed for. Aeroseal Envelope can meet any IECC, Passive House, LEED, Well Standard, ENERGY STAR, or Net Zero requirement.

A home that is too tight can be a bad thing if the space isn’t designed for that level of tightness. The popular saying “build tight, ventilate right” applies here and works both ways. Building tight without proper ventilation could cause issues with indoor air quality (IAQ) in the space. On the flip side, a leaky home with proper ventilation could cause the mechanical system to not work as it is designed. Because Aeroseal Envelope can dial in the desired tightness of the space it removes the guesswork and ensures that the home is only as tight as the space is designed for.

What is the expected lifespan of this product?2023-09-13T17:26:45-07:00

Third-party lab testing reveals Aeroseal Envelope withstands a simulated 50-year durability test, with little or no seal degradation.

Is it safe for inhalation?2023-09-13T17:27:33-07:00

Yes, but not 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.

When can construction work recommence?2023-09-13T17:28:27-07:00

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. During this time, the sealing equipment and coverings are removed.

Do you wear protective gear?2023-09-13T15:19:06-07:00

Yes, our installation crew wears a respirator, eye protection, and gloves as well as protective clothing.

Can a home be too air tight?2024-01-24T09:00:12-08:00

Simply put, there is no such thing as a home being too tight or that a home should breathe. However, there can be a situation where a home is not properly ventilated for the tightness of the home. If a homeowner does not wish to have a ventilation system installed, we can seal the home to a level far beyond code mandates but that will not require ventilation systems.
