What are flooring trims ( door thresholds ) used for?

Floor trims are an essential component in flooring installations, providing both functional and aesthetic benefits. They help to bridge gaps between different floor coverings, create smooth transitions, and protect the edges of flooring materials. Here’s a closer look at the purpose of floor trims and their various applications.

1. Bridging Height Differences

Floor trims, such as ramps, semi ramps and transition strips, are used to bridge height differences between flooring materials. For example, if a wooden floor meets a tiled surface that sits higher, a ramped transition trim ensures a gradual slope, preventing trip hazards and providing a seamless connection.

2. Covering Expansion Gaps

Engineered wood flooring requires expansion gaps around the perimeter to allow for natural expansion and contraction due to temperature and humidity changes. Floor trims help to cover these gaps while maintaining the floor’s integrity and appearance. Ideally, a skirting board should be installed after the flooring is laid. However, in situations where clients prefer not to remove existing skirting boards, a scotia or quadrant trim can be used to effectively conceal the expansion gap while providing a clean and finished look.

3. Enhancing Aesthetic Appeal

Floor trims contribute to the overall aesthetic of a space by creating neat and professional finishes. They are available in various styles, colors, and materials to complement different flooring designs, ensuring a cohesive look.

4. Protecting Flooring Edges

Floor trims act as a protective barrier, reducing the risk of chipping, cracking, or fraying, thereby extending the lifespan of the flooring.

5. Improving Safety

Uneven flooring transitions can pose a tripping hazard, particularly in high-traffic areas. Floor trims create a smooth and stable walking surface, reducing the risk of accidents and improving overall safety in homes and commercial spaces.

6. Concealing Wiring and Cables

In some cases, floor trims can be designed to house electrical cables and wiring, keeping them hidden while maintaining easy access for maintenance. This is particularly useful in office spaces and entertainment areas where multiple cables are required.

Types of Floor Trims and Their Uses

Full Ramp Trims (18-22mm & 16-18mm) – Ideal for bridging height differences between flooring types.
Semi Ramp Trims – Suitable for slight height differences where a subtle transition is needed. - Ideal from wood flooring to carpet.
Twin Trims – Used between two floors of the same level to create a seamless connection.
End Section Trims – Designed to provide a finished edge when a floor meets a wall, threshold, or doorway.

Conclusion

Floor trims play a crucial role in ensuring a well-finished, safe, and durable flooring installation. Whether used for height transitions, edge protection, or aesthetic enhancement, selecting the right floor trim can significantly improve the longevity and functionality of a flooring system.
