Thermal Break Installation in Industrial Metal Roofing: What You Need to Know

Metal roofing is a top choice for industrial buildings across Colorado. It’s durable, low-maintenance, and holds up well to snow, hail, and strong sun. But without proper insulation, metal roofing can create major energy loss and moisture problems. That’s where thermal breaks come in.

What Is a Thermal Break?

A thermal break is a layer of insulating material that stops heat from passing through metal components. Metal is a strong conductor of heat and cold. So without a thermal break, metal roofs can:

• Transfer heat into the building in summer

• Transfer heat out in winter

• Cause condensation to form on the interior side

Thermal breaks block that heat transfer, reducing energy costs and keeping interiors comfortable.

Why Are Thermal Breaks Important for Metal Roofs?

Here’s how thermal breaks protect industrial properties in Colorado:

1. Prevent Condensation

In winter, warm interior air hits the cold underside of a metal roof. That temperature difference can cause condensation, which leads to:

• Water drips inside the building

• Corrosion of roof panels and fasteners

• Mold growth in insulation and framing

Thermal breaks help keep the interior side of the metal warmer, reducing condensation risk.

2. Improve Energy Efficiency

Thermal breaks reduce thermal bridging—the movement of heat through fasteners, clips, and framing. That means:

• Less heating and cooling loss

• Lower HVAC loads

• More stable indoor temperatures

In industrial spaces with large square footage, this can lead to major savings.

3. Enhance Occupant Comfort

Temperature swings near uninsulated rooflines can be dramatic. Thermal breaks help moderate these areas, making the building more usable and comfortable year-round.

How Are Thermal Breaks Installed?

Thermal breaks can be installed in different ways depending on the roof structure.

On Open Framing Systems:

• Insulated clips or spacers are placed between metal roof panels and the framing (like purlins).

• These help isolate the panel from direct contact with the metal frame, reducing thermal transfer.

On Solid Deck Systems:

• Rigid insulation boards (like polyiso or mineral wool) are placed between the deck and metal roof panels.

• A slip sheet or vapor barrier is sometimes added to allow for thermal expansion without tearing the insulation.

Key Considerations:

• Use high-performance rigid insulation with the right R-value for your zone.

• Ensure insulation layers are continuous at edges, penetrations, and seams.

• Confirm all materials meet code (IBC, IECC, and local energy codes).

FAQ

What type of insulation works best for thermal breaks in metal roofs?

Polyisocyanurate (polyiso) is commonly used due to its high R-value per inch and compatibility with metal roof systems.

Can you retrofit thermal breaks on an existing metal roof?

Yes, retrofitting is possible. It may involve adding insulation above the existing panels (overdeck insulation) or removing the panels to add a thermal break between the roof and purlins.

Are thermal breaks required by code in Colorado?

The IECC and local building codes increasingly require continuous insulation and reduced thermal bridging in commercial roofs. Always check with your local jurisdiction or hire a licensed roofing contractor familiar with Colorado energy code requirements.
