Chicago, IL Air Sealing

DNR Construction provides Department of Energy, Energy Efficiency & Renewable Energy (EERE) air sealing services to Chicago, IL and the surrounding areas. Simply adding insulation to a home is only part of the solution. This is why we perform diagnostic testing (blower door tests) on every home. The blower door test measures air tightness. Air leakage is the uncontrolled flow of air through gaps and cracks in the fabric of a building. Improving air tightness in a dwelling can reduce air leakage. This means that there are no breaks or gaps in the envelope of the building fabric and there is complete control over the ventilation system with the building.

An airtight property does not mean there is insufficient air flow, it means there is controlled air flow.

Our EERE Air Sealing Services Include:

• Blower Door Tests
• Caulk and weatherstrip doors and windows
• Caulk and seal plumbing, ducting, electrical, etc
• Foam sealant application for large air leaks
• Insulation services
• Storm window installation

All these organizations work to provide financial and educational resources for homeowners interested in making their home more energy efficient. We are also preferred contractors for many energy raters who complete detailed audits for homeowners.
