Hi croig, I'm honestly not sure what type of shiplap this is. I told the builder the width (which was 6" or 7" I think) and look that I was going for and he just made samples for me to approve. I also requested a "square groove" which helps achieve the look shown. I am sorry that I couldn't be of more help!

Hi Craig,

here is a link to a company that does ship lap. You will need to copy and paste it into your browser. https://windsorone.com/products/shiplap/

Ask them who is a dealer near you. Windsor One make nice traditional trim.

Good Luck.

Thank you for your response, Stockwell!
