Frequently Asked Questions

What does a door threshold do?

A door threshold seals the gap beneath a door while creating a transition between floor surfaces. It helps improve energy efficiency, weather resistance, and accessibility.

Which threshold is best for exterior doors?

Exterior doors commonly use adjustable thresholds, interlocking thresholds, thermal break thresholds, or rubber seal thresholds depending on climate and performance requirements.

What is a thermal break threshold?

A thermal break threshold includes an insulating barrier that reduces heat transfer between indoor and outdoor environments, improving energy efficiency.
