A Smarter Solution for High-Performance Penetration Sealing

At Alpine Energy Solutions, we constantly seek better ways to help builders and homeowners improve energy efficiency, comfort, and durability. One simple yet powerful upgrade we recommend is airtight gaskets for mechanical penetrations. That’s why we’re excited to highlight the Pro Clima gaskets available through 475 High Performance Building Supply.

What Are Pro Clima Gaskets?

Pro Clima offers a line of airtight, flexible gaskets specifically designed for sealing around:
– Round ducts
– Conduits and pipes
– Electrical cables and wire bundles

These gaskets install quickly and maintain an airtight seal even as materials expand and contract over time. They’re compatible with various substrates, including wood, OSB, and membranes like Pro Clima INTELLO or SOLITEX weather barriers.

Why Use Gaskets Instead of Caulk or Spray Foam?

Traditional methods like spray foam and caulk can shrink, crack, or pull away from surfaces, especially with temperature swings and material movement. Gaskets, on the other hand:
– Stay flexible for long-term durability
– Allow for movement without compromising the seal
– Provide repeatable, high-quality installations
– Are safer and cleaner to install—no off-gassing or mess

We often see significant air leakage during blower door testing caused by poorly sealed penetrations. Upgrading to a gasket system helps reduce leakage and improve test results, especially for homes pursuing Passive House or 2021 IECC compliance.

Our Take

We’ve tested plenty of houses, and one thing is clear: every penetration counts. If you’re aiming for airtightness, switching to Pro Clima gaskets is one of the easiest ways to improve performance without adding complexity. Whether you’re a builder, homeowner, or architect, these gaskets are a smart investment.
