Schluter Strip: What It Is and Where It's Used in Tile Installations

A Schluter strip is a metal transition profile manufactured by Schluter Systems, used at the edges of tile installations to provide a clean finished edge, protect tile from chipping at vulnerable corners, and create smooth transitions between tiled surfaces and adjacent flooring or changes in plane.

In the US remodeling market, the brand name Schluter has become broadly synonymous with metal tile trim profiles regardless of manufacturer, similar to how Kleenex is used for facial tissue. Schluter Systems products are specified by name in most professional tile installation scopes.

At Phoenix Home Remodeling, Schluter and equivalent metal trim profiles are used wherever a tile edge requires a finished transition. Eliminating exposed, unfinished tile edges is a mark of professional installation and prevents chipping at the corners most vulnerable to impact.

Because an unprotected tile edge exposed to foot traffic, cleaning, or incidental impact will chip. The corner of a tile is its weakest point, and even porcelain and ceramic will crack at an exposed edge over time. A metal edge profile covers the tile corner with a durable cap, directing any impact load to the metal rather than the tile. It also creates a clean visual transition that is part of a finished, professional installation. Absent edge profiles, installers rely on grout alone at edges, which cracks and deteriorates.

JOLLY: A simple L-shaped profile that caps the edge of a tile installation at a wall or countertop edge. The most commonly used Schluter profile in residential remodeling. Installed during tile setting so that the tile butts against the profile leg.

RENO: A T-shaped transition strip used between tile and an adjacent floor material of different height. Creates a smooth, ramped transition between flooring surfaces with different thicknesses.

SCHIENE: A flat transition profile that bridges the joint between tile and an adjacent surface at similar height. Often used at tile-to-hardwood floor transitions.

DILEX: An expansion joint profile that accommodates movement between large tile fields. Required at changes in plane, at structural joints, and in large tiled areas subject to thermal movement.

KERDI-BAND: A waterproofing membrane strip used at seams, corners, and transitions in wet areas. Part of the same Schluter system and frequently used in conjunction with JOLLY profiles at shower niches and bench edges.

Caulk is appropriate at changes in plane where movement is expected. But it is not a substitute for a metal edge profile at an exposed tile corner. Caulk at an unprotected tile edge will crack and separate as the tile edge chips over time. Metal profiles protect the tile itself, which is the function caulk cannot perform.

Yes, and that is intentional. A correctly installed JOLLY profile creates a clean, visible metal edge at the tile boundary. The profile should be treated as a design element with a finish that coordinates with fixtures and hardware. A correctly specified and installed profile looks intentional and professional. An improperly sized or mismatched one is equally visible and detracts from the installation.

We specify the appropriate profile type for every tile edge in our installations. Finish is confirmed during the design phase to coordinate with fixtures and hardware. Our tile installers set profiles as part of the tile installation process, not as an afterthought. No exposed, unprotected tile edges are left in our finished projects.

• What profile type are you using at each tile edge location?
• What finish are you specifying and does it coordinate with my fixtures and hardware?
• Are expansion joint profiles being used in large tiled areas or at changes in plane?
• When in the tile sequence are profiles installed?
• Are there any exposed tile edges in this design without a metal profile?
