What type of wood is this?

This is a premium Douglas Fir.  Douglas Fir is a evergreen conifer species native to the west coast.  It is primarily harvested in Oregon, Washington, and British Columbia.  Douglas Fir is known for its beauty, excellent strength, dimensional stability, and solid performance in exterior environments.   


What is the grade of wood?

The technical grade is a C&btr grade, which means the board will be clear except for the occasional, if any, penny sized knots.  In clear fir, there are two types of grains - mixed grain and vertical grain.  This is a mixed grain product which means you'll see typical grain and growth rings on the surface of the board.  Mixed grain is much sustainable, available, and cheaper; it also leaves a better stained look with more variation and color contrasts that showcase the natural beauty of the wood.  


Can I still paint this, or is this a stain grade only product?

This is primarily intended to be a stain grade wood - meaning you would finish this with stain, wash, or clear finish.  It could be painted, however you'd be overpaying for that final appearance.  


Can this be used for ceilings?  

This can definitely be used for ceilings.  Fir is relatively light and is easy to work with, especially for a ceiling application.  


Can I install this directly to the studs and skip the drywall step?  

Yes, and it's fast and easy!  Installed shiplap will cost you roughly the same as installed drywall.  However certain municipalities still require sheetrock per local building code.  


Can I install this directly over my drywall?  

Absolutely, but you'll still want to fasten to the studs where possible, and you'll need to be careful of your interior window and door trim.  Make sure you plan ahead and evaluate your current door and window trim.  Our shiplap is 3/4" thick, so you could lose your shadow line if you have a thin reveal on your current trim.  


Can I use this product in a exterior application?

One of the benefits of Douglas Fir is that it's one of the few wood species that actually performs decently well in exterior applications.  It has natural oils and resins that make it resistant to rot and decay, so it's a good fit for exterior applications.  It is still recommended that all six sides of the board get properly finished (stained, painted, or sealed) before installing.  But overall, yes, this can absolutely be used in an exterior application and often does.  


It says this is a mixed length product, what does that mean? 

Clear wood fiber isn't abundant.  It only comes from certain parts of very mature trees, so you only get certain amounts of clear wood when you process a log.  Given that, the only way to sell this product is in what's called a random length mix.  That basically means that you will get a mix of 8' - 16' lengths.  You won't be able to specify all 16' lengths, for example.  Sometimes short lengths can be specified, but it all depends on availability.  


Are both sides of this product nickel gap?

The primary face is a 1/8" nickel gap.  The reverse face is what's known as a V-groove, meaning the two pieces will form a V when they come together at the tongue and groove.  The reverse face is 100% usable, and we designed it this way to give you the flexibility to choose from both options.


I want to stain my shiplap.  Which product is better … the Raw Pine or the Clear Fir?

It all depends on the look you're going for.  If you want to see knots and a more rustic look, then you should definitely go with the Raw Pine.  If you want a more upscale and sophisticated look, we believe the Clear Fir is the way to go - it is slightly more modern.

Why Douglas Fir?   

Douglas Fir is one of America's abundant tree species and is completely sustainable.  There are three main benefits to Douglas Fir over other wood species:  

1) Color & Grain

Douglas Fir has a warm reddish-brown hue with prominent grain patterns, making it visually appealing for both structural and decorative purposes.  It's natural auburn colors and distinguished grain pattern make it very visually appealing to the naked eye.  

2) Dimensional Stability 

All woods shrink and swell to some degree as their moisture content fluctuates with atmospheric conditions. However, Douglas Fir tends to be dimensionally stable, meaning it's less prone to warping, twisting, or shrinking compared to other types of wood.

3) Workability

Douglas Fir typically has a straight grain, which makes it easier to work with and results in a smoother finish.  It's relatively easy to saw, nail, and glue, making it suitable for various woodworking projects.
