Every project headline
Timber purlins and joists form the roof and floor framing in timber framed buildings. The old school way to do the joinery is to dovetail them in. Unfortunatly, the beautiful dovetail is hidden in the finished building, but its strenght and integrity is not. It is a strong joint that lasts over time.

When very heavy loads are involved in a floor or roof system, we use shouldered lap joints. The lap joint allows us to maintain cross sectional area in the girts (main carrying beams). See details below, and click on the images to open active 3d pdf's. (Mac users will need to download the pdf file to open it).

Give us a call at 802-886-1917 or e-mail to learn how we can help with your post and beam project. Scroll down to learn more about timber framing and post and beam construction.

Lapped Purlins on Timber Rafter

In order to reduce the amount of wood that is cut out of this top chord, the purlins for the roof system were lapped in and screwed with log hog screws. There is a one inch deep cut in the top of the top chord, and a one inch cut in the bottom of the purlin.
