What are perimeter trims used for? Perimeter trims finish the edge of a floor where it meets a wall, skirting or fixed obstruction. They cover the expansion gap left around timber floor installations, protect the floor edge from damage, and give the installation a neat, professional finish.
Why do timber floors need an expansion gap and edge trim? Timber flooring naturally expands and contracts with changes in temperature and humidity. An expansion gap is left around the perimeter to allow for this movement, and a perimeter trim covers that gap, preventing debris ingress and damage while maintaining a clean sightline where the floor meets the wall.
Are perimeter trims suitable for ceramic floors as well as timber? Yes. CAT’s perimeter and floor edging trims are suitable for both timber and ceramic floor installations, providing a neat edge finish and, where needed, allowing for expansion at the floor perimeter.
What materials are perimeter trims available in? Our perimeter trims are available in aluminium, brass and stainless steel, with additional PVC options for certain profiles. Aluminium suits most commercial specifications, brass and stainless steel are chosen for premium or high-visibility finishes, and PVC offers a cost-effective alternative.
What’s the difference between the PTA, Timberline and Kliks Slim ranges? PTA is our standard perimeter trim profile, Timberline is designed specifically for timber floor edge finishing, and Kliks Slim End Stop profiles are used to terminate Kliks flooring trim runs cleanly at a wall or fixed point. Each is available across our core material and finish options.
What do OSF and ISF mean on perimeter trim product names? OSF and ISF refer to the fixing configuration of the profile, outer stick fix and inner stick fix respectively, which determines how the trim is positioned and secured relative to the floor edge. Check the individual product page for the correct option for your installation.
Can I order a free sample of a perimeter trim before specifying? Yes. Every perimeter and floor edging trim on this page includes the option to order a free sample, so you can check the finish and profile before specifying or ordering for a project.
Do you offer bespoke perimeter trim profiles? Yes. If a standard profile doesn’t suit your project, CAT offers a bespoke service and in-house fabrication to produce custom perimeter and floor edging trims.
