Threshold

Definition

A threshold is the wood or metal beveled floor piece at door openings that commonly separates non-continuous floor types.

Purpose

The purpose of a threshold is to provide a smooth and aesthetically pleasing transition between different flooring materials or levels and to protect the edges of the flooring. It also helps to seal the space beneath doors, preventing drafts and moisture from entering.

Examples of Use

1. Entryways: Thresholds are used at the base of exterior doors to provide a barrier against weather elements and create a finished look.
2. Room Transitions: In homes and offices, thresholds separate different flooring types, such as from tile to carpet, ensuring a seamless transition.
3. Accessible Design: Thresholds are designed to be low-profile or ramped for accessibility, making transitions easier for wheelchairs and mobility aids.

Related Terms

• Door Sill: The horizontal piece below a door that forms the bottom of the frame.
• Transition Strip: A strip used to connect two different types of flooring, often used in conjunction with thresholds.
• Reducer: A type of threshold that transitions between floors of different heights.

Notes

• Material Choice: Thresholds can be made from wood, metal, or composite materials, each providing different aesthetic and functional benefits.
• Customization: Thresholds can be customized to match the design and height requirements of specific applications.
