Air Sealing

For our air sealing services, we use a variety of materials to help tighten up a home’s heating envelope.

Knauf Ecoseal Plus is a high-performance elastomeric sealant designed to improve airtightness in residential construction. It creates a durable, flexible seal around penetrations, seams, and joints, reducing air leakage and boosting energy efficiency. Unlike traditional caulks or foams, its spray-on application ensures complete coverage in critical areas, helping homes stay comfortable and energy-efficient.

Meeting air changes per hour (ACH) standards is essential for code compliance, and Ecoseal Plus makes it easier. Its quick-drying, water-based formula adheres to common materials, making it ideal for new builds and retrofits. Used alongside quality insulation, it helps homes pass blower door tests and supports sustainable building practices.

Additionally, gasket foams and window seal foams play a crucial role in improving a home's airtightness by sealing gaps that could allow air leakage.

Gasket foams are commonly used around electrical outlets, plumbing penetrations, and between framing components to create a flexible, long-lasting seal.

Window seal foams expand to fill the spaces between window frames and rough openings, preventing drafts and moisture infiltration.

When used alongside Knauf Ecoseal Plus, these foams enhance overall air-sealing performance. Gasket foams provide continuous protection in areas that may shift over time, while window seal foams ensure a tight fit around openings. Together, they help homes meet ACH standards, improve energy efficiency, and enhance indoor comfort.
