Exterior Duct Insulation

Reliable Solutions for Exterior Duct Insulation

CROWN INSULATION LLC installs exterior duct insulation systems designed for durability, weather protection, and energy efficiency. The process includes:

1. Surface Preparation – Ductwork is inspected and cleaned to ensure proper fit.

2. Insulation Application – Insulation material is measured, cut, and fitted around the duct to provide thermal protection.

3. Seam Treatment – Insulation joints are sealed to prevent thermal gaps and moisture intrusion.

4. Metal Jacket Installation – A protective metal cladding (aluminum or galvanized steel) is applied over the insulation, secured with bands, screws, or rivets.

5. Weatherproofing – All seams, edges, and penetrations are sealed to resist rain, UV exposure, and environmental conditions.

6. Final Inspection – Coverage, fastening, and sealing are verified to meet mechanical insulation standards and ensure long‑term performance.

This system ensures exterior ducts are protected against weather, mechanical damage, and energy loss.

Why Exterior Duct Insulation?

Exterior duct insulation keeps supply air at the right temperature as it travels through rooftop or outdoor ductwork, which cuts energy loss and helps control utility costs. It limits condensation and corrosion risk by separating cold duct surfaces from humid outdoor air. The result is more reliable HVAC performance and longer service life for exposed ducts.

Metal Jacket Protection

With a metal jacket system, CROWN INSULATION LLC adds a durable aluminum or galvanized steel shell over the insulation to shield it from rain, UV, and impact. Properly sealed seams and penetrations help keep moisture out and maintain insulation integrity over time. This combination of thermal insulation and hard metal cladding provides a clean, rugged finish that holds up in harsh exterior conditions.
