From cold to comfortable: Properly insulating your crawlspace
Rock Wool Insulation
Did you know there’s an inspection specifically designed to ensure insulation performs as intended? It’s called QII—short for Quality of Insulation Installation—and it’s a game-changer for improving the energy performance of homes and buildings.
Why does QII matter? Insulation is only as effective as its installation. Unfortunately, many insulation jobs—whether done by homeowners or professionals—fall short. Common mistakes like gaps, compression, and voids can drastically reduce thermal performance, leading to uneven temperatures, drafts, higher energy bills, and even moisture-related issues.
QII ensures insulation is installed to exacting standards, minimizing these problems. The process includes a detailed inspection to confirm insulation is properly placed, with no gaps or obstructions, and is in full contact with air barriers. For new construction, QII is often required to meet higher energy efficiency standards, such as those outlined in California’s Title 24 Building Energy Efficiency Standards.
Key Benefits of QII:
Enhanced Energy Efficiency: Proper insulation reduces energy loss, lowering heating and cooling costs.
Improved Indoor Comfort: Say goodbye to hot or cold spots in your home.
Better Air Quality: Correctly installed insulation reduces pathways for air leakage, helping control pollutants and allergens.
Moisture Management: Proper installation minimizes the risk of condensation and mold growth.
Code Compliance: QII is a requirement for certain high-performance building certifications, such as California’s CalGreen and programs like Energy Star and LEED.
For builders and homeowners aiming for Passive House, Net Zero, or Living Building Challenge certifications, QII is a critical step toward creating a truly high-performance, sustainable home. It’s not just an inspection—it’s peace of mind that your home is optimized for energy efficiency, comfort, and longevity.
When it comes to insulation, remember: It’s not just what you use, but how you use it that makes all the difference.
