I’ve got a new construction project that requires 1×1 “Walnut” Slats to be run vertically on the exterior of the home. These need to have a walnut look but not necessarily made of walnut, or wood. My concern is that they will have a full Western exposure, as well as being part of the home’s entryway, so sun damage with traditional wood is a problem.

Is there any type of exterior finish solution (faux, PVC?) that people are using in place of real wood to avoid damage while retaining this look? Would Cedar be an option?

What are the maintenance requirements and expectations for consistent, non-fade coloring?

Bare cedar will fade and turn gray over time; maintenance will be required to maintain the color. If consistent coloring and minimal maintenance is a requirement, then amount of sun exposure could also be an issue; south and west facing surfaces will change at different rates than east and north facing surfaces, for example.

You might look into the newer composite decking materials such as Trex. They have improved their UV fade resistance and there are many color choices.

You could check into engineered wood siding. I see it quite a lot around my neighborhood. It’s supposed to be a lot more durable than real wood.

Take a look at thermo treated material.
Here is a link about what it is. Turns wood a natural brown color also.

Another option that still requires some maintenance is ipe. It does grey out in the elements but a simple coat of oil like penofin will bring it back for a couple of years.

IMO, all the engineered products look “engineered”. If the customer is ok with that then the fake wood decking is a good option.

Have your say...
