Why Do Metal Panels Create Gaps?

Profiled metal roofing is not flat.

The ribs and valleys create spaces where the panel meets:

• Eaves
• Ridges
• Flashing

Closure products are shaped to fit those profiles.

What Do They Help With?

Depending on the system, closures may help reduce entry of:

• Wind-driven rain
• Snow
• Insects
• Debris

while completing the intended roof detail.

Are All Closures Foam?

No.

Systems vary and may use different materials and ventilation designs.

Ridge Ventilation Needs Special Attention

A ridge detail may need airflow.

That means a solid closure should not be substituted where a ventilating closure system is required.

Metal Roofing Performance Depends on the Details Between the Panels Too.
