Door Thresholds for Commercial & Residential Applications

Door thresholds are an essential part of any doorway system. Installed at the bottom of a door opening, thresholds help create a secure transition between floor surfaces while reducing drafts, moisture infiltration, dust, insects, and energy loss. They also work together with door sweeps, door bottoms, and weatherstripping systems to improve the overall performance of the opening.

At Trademark Hardware, we offer one of the largest selections of door thresholds available online. Our inventory includes aluminum thresholds, bronze thresholds, brass thresholds, stainless steel thresholds, thermal break thresholds, and heavy-duty commercial-grade solutions designed for high-traffic environments.

Whether you're upgrading an exterior entry door, replacing an existing threshold, improving ADA accessibility, or specifying hardware for a commercial facility, you'll find solutions available in multiple widths, heights, finishes, and custom lengths.

Popular Door Threshold Types

Different applications require different threshold designs. Some thresholds are designed primarily for weather protection, while others focus on accessibility, floor transitions, or heavy-duty commercial use.

  • Flat Thresholds – Ideal for smooth transitions and commercial applications.
  • Interlocking Thresholds – Create a tighter seal when paired with compatible door bottoms.
  • Adjustable Thresholds – Allow height adjustment to compensate for wear and changing conditions.
  • Thermal Break Thresholds – Improve energy efficiency by reducing heat transfer.
  • Rubber Seal Thresholds – Provide enhanced weather protection and air sealing.
  • Half Saddle Thresholds – Popular for residential and light commercial installations.
  • Stainless Steel Thresholds – Excellent for demanding environments requiring corrosion resistance.
  • Bronze & Brass Thresholds – Durable architectural solutions with a premium appearance.

Frequently Asked Questions

What does a door threshold do?

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

Which threshold is best for exterior doors?

Exterior doors commonly use adjustable thresholds, interlocking thresholds, thermal break thresholds, or thresholds with integrated sealing systems to provide better protection from weather and drafts.

What materials are door thresholds made from?

Door thresholds are commonly manufactured from aluminum, stainless steel, bronze, brass, wood, and composite materials depending on the performance requirements of the application.

Can thresholds be cut to custom sizes?

Many threshold products can be ordered in custom lengths or cut to fit during installation, making them suitable for both replacement and new construction projects.
