Corners: Miter Cuts vs Corner Units

Ask any stone mason or tile setter and they’ll tell you that what separates an average contractor from a great contractor is how good their corners look. Corners are a natural focus point on any installation as the change in plan breaks up an otherwise ordinary field of stone or tile and creates a contrast that catches the eye. Columns can be almost exclusively corners, making them one of the most difficult projects to tackle. With all that focus on a relatively small part of a project, you can see why installers focus on the corner and use all the tools available to them to make a corner looks its best. Let’s take a look at the two most common methods of turning a corner using a stone veneer panel system – miter cuts and corner units.

Miter Cuts

When Norstone first started making thin stone veneer panels almost 15 years ago we told anyone installing our product to miter cut one of our 6” tall x 24” long field units to form an inside or outside corner. This process consisted of cutting a panel using a straight blade into two separate pieces, then back cutting each of those pieces using a 45 degree angled blade or wet saw rig. Since the rock panels vary in thickness, this process was only partially about making the cuts – a good installer would go back and selectively trim pieces here and there along the corner to make the two sides come together nice and tight.

Properly executed miter cuts are a great look, producing a clean, almost sharp edge that runs vertically along the outside corner, making them ideal for a modern clean look, but posing a challenge to under-experienced installers and slowing down production for even the most experienced of install team.

As we continued to work more closely with both architects and designers that specified our products and the masons and tile setters that installed them, one of the areas they were in agreement about was the need for a corner unit. For the specifiers, it made their job easier to specify a system and more importantly insured their vision of the project stayed true and didn’t get fouled up by a hasty installation team trying to miter cut in the field. For a tile or stone installer, a corner system was a no brainer – even at a marginally higher cost, a good corner unit system allows them to keep production high and offset the higher labor costs of miter cutting a corner in the field.

The result of this feedback is our industry leading outside corner unit. Each unit consists of two pieces, both 6” tall to match our field units, and alternating in either a 8” or 16” length. These two pieces have “fingers” which are really extensions of individual pieces of stone in each panel, that are left with a natural cleft on the faces of the stone that face out. The two pieces of each corner unit fit together and are specifically made for each other, in fact each corner unit is hand fit together to check for quality and a tight fit before being boxed up and leaving our factory. The result is an easy to install outside corner unit that creates a natural looking rounded corner that we feel is the best looking corner in the thin stone veneer market. Many manufacturers don’t have a corner option at all, and if they do, instead rely on a more basic dovetail style corner, which while much easier to manufacture, offers a far less seamless look to the corner. Corners are just one of many details that make Norstone better than other thin stone veneer manufacturers.

While both the miter cut and corner unit options are still used everyday by our clients, we highly recommend our outside corner units. Unless the installer has the right experience and tools for the job, and the customer is looking for the specific clean line look that a miter cut corner provides, a better option in almost every situation will be our outside corner unit system. Our in house design reps and technical team are always available to answer any question you might have about a specific corner condition on your project, so never hesitate to call us with your questions, and until then turn your corners with care!
