Frequently Asked Questions:

When should I use 3x6 versus 2x6?

2x6 T&G Roof Decking will cover most residential applications.  3x6 T&G Roof Decking is primarily used for commercial projects, but it may be required for other areas.  We have full time engineers that can assist with answering this question.  

Can I get this pre-finished?

No - these are sold as raw timber only.  Pre-finishing sounds great in theory, but there is a lot of jobsite work required during installation that is messy, dirty, and rough on the product.  Over the years, we've found that it's best to get the product finished on site.  

If I want to make a full timber structure, which products should I match this up with?

Being a Douglas Fir Roof Decking, these pair up beautifully with our Douglas Fir Timbers, and our Douglas Fir Glulam Beams.  In fact, our personal office is a timber frame building comprised of Douglas Fir Glulams and 3x6 T&G Roof Decking.  

Can I use both sides of this product?

The product is intended to be installed with the V-Groove face exposed.  The backside is a tight butt T&G.  In theory it can be left as is for a floor, but often times it is finished over with a formal layer of subfloor and flooring or sheathing and roofing.  

Can I specify lengths?

We do our best to make any project possible.  If you have a specific length you need, reach out to us and we'll let you know what's possible.  

Why should I use Douglas Fir versus other species like Yellow Pine or SPF?

For one, it starts with beauty and appearance.  We believe that Douglas Fir is the best look and most visually appealing product available.  The auburn tones and beautiful grain make for a stunning look.  

Two, Douglas Fir is also a great combination of strength and workability.  You'll get long spans and great load tables with Douglas Fir.  It's also very dimensionally stable and won't bow, twist, or crook as much as some other wood species.  

Finally, Douglas Fir stains and finishes the best.  You will be making an investment in this product, and you want it to look as good as possible.  Douglas Fir takes stains and finishes extremely well, leaving a professional and polished look.  

Can I get this end-matched or pre-drilled?

No - those are not available options.
