Summary: Achieving an airtight home is crucial for energy efficiency, comfort, and indoor air quality. This requires attention to detail and choosing effective insulation. Blower door tests with fog reveal air leaks, allowing targeted repairs. Through sealing techniques and continuous improvement, a responsible contractor ensures minimal air leakage. MAG Insulation offers various insulation solutions in Mid-Michigan to achieve energy-efficient homes.
The Importance of Airtightness in Homes
Creating an airtight home is a cornerstone of energy efficiency and creating a comfortable living space. Airtightness prevents drafts and temperature fluctuations, reducing reliance on heating and cooling systems, which translates to lower utility bills. Moreover, it bar pollutants and allergens from entering, improving indoor air quality. When a home is airtight, it better retains heat during winter and keeps cooler air inside during summer.
The Role of Insulation in Achieving Airtightness
Insulation is key to achieving airtightness. It acts as a thermal barrier that minimizes heat transfer between the inside and outside. Proper insulation minimizes the need for heating and cooling, which leads to reduced energy consumption. There are several options for homeowners in Mid-Michigan, from retrofoam insulation to insulation products from Koala and USA Insulation. Each aims to provide thermal performance and contribute to airtightness.
Using the Blower Door Test with Fog to Identify Air Leaks
The blower door test is essential for evaluating a home’s airtightness. By pressurizing the home and observing areas where fog escapes, homeowners can identify air leaks. The test reveals the air leakage rate, shown as air changes per hour (ACH). With fog, the test visually illustrates air movement through gaps, making it clear where further sealing is needed.
What is the Blower Door Test?
In a blower door test, a powerful fan mounts to an exterior door frame, depressurizing or pressurizing the home. It measures the airflow required to maintain a specific pressure, calculating the home’s air leakage rate. The combination of the blower door test and fog allows for a visual representation of air leaks, showing where the building envelope needs improvement.
Attention to Detail for Achieving Airtightness
The Devil is in the Details
Building an airtight home requires meticulous attention to detail. Jesse from Homestead Builders showcases this in the video. He emphasizes products and techniques that minimize air leakage. One key aspect is Zip System sheathing, which creates a continuous air barrier. Even before open-cell foam insulation is added, the Zip System sheathing prevents air leaks, significantly contributing to airtightness.
Sealing Techniques and Products
Various products like Seam’s fum tape, Quick flash boots, and Zip System liquid flash are used to seal different areas. These products ensure that minor leaks are meticulously sealed. For example, Seam’s fum tape seals the bottom plate of the home, adhering securely to the concrete foundation. Quick flash boots seal smaller areas, while Zip System liquid flash addresses specific spots on the sheathing.
The Scot True Method
Jesse employs the “Scot true method of monopoly framing,” which he discovered from Scott True’s YouTube video. Instead of foam insulation, Jesse’s framer uses Zip System sheathing beneath the fascia, adding tape around the subfascia and roof decking. This technique is budget-friendly while achieving excellent airtightness.
Insulating Outlets
Electrical outlets often contribute to air leakage. Jesse tackles this by using standard blue plastic boxes and Great Stuff spray foam to fill gaps around them. Putty pads add another layer of sealing, ensuring no air passes through these points.
Challenges and Lessons Learned
Identifying Shortcomings
Even with meticulous planning, some challenges arise. During the blower door test, air leaks were found in areas where peeling stick was used as an air barrier on the roof deck. Although peeling stick adhered well to itself, it wasn’t as effective on the OSB substrate, causing some leakage. Jesse realized that products like the Zip System might have provided a more reliable air barrier, emphasizing the need to select the correct materials.
Continuous Improvement
Through this process, Jesse acknowledges the importance of learning from mistakes. Using better air barrier solutions like the Zip System, particularly on roof decks, helps achieve airtightness. The team also tried an innovative door installation technique using HardieTap and liquid flash, which created an airtight and watertight seal, bypassing traditional methods to achieve better results.
Next Steps and Future Improvements
Plan for Enhancement
Jesse and his team plan to install open-cell spray foam insulation in the attic for added airtightness. This insulation will complement the existing barrier, boosting the home’s thermal performance. The lessons from this project—like the need for reliable air barrier solutions—guide future improvements to deliver even tighter, energy-efficient homes.
