What is a Purlin in Timber Trusses Roofing Members.

A horizontal structural member which supports roof covering or a longitudinal member in a roof frame, usu. for supporting rafters or the like between the plate and the ridge.

In architecture, structural engineering or building, a purlin (or historically purline, purloyne, purling, perling) is any longitudinal, horizontal, structural member in a roof except a type of framing with what is called a crown plate. In traditional Timber framing there are three basic types of purlin: purlin plate, principal purlin and common purlin.



Purlin plates in wooden construction
A purlin plate in wooden construction is also called an "arcade plate" in European English, "under purlin", and "principal purlin". The term plate means a major, horizontal, supporting timber. Purlin plates are beams which support the mid-span of rafters and are supported by posts. By supporting the rafters they allow longer spans than the rafters alone could span thus allowing a wider building.


Principal purlins in wood construction
Principal purlins in wood construction, also called "major purlin", "side purlin". Principal purlins are supported by principal rafters and support common rafters in what is known as a "double roof" (a roof framed with a layer of principal rafters and a layer of common rafters). Principal purlins are further classified by how they connect to the principal rafters: "Through purlins" pass over the top; "butt purlins" tenon into the sides of the principal rafters; "clasped purlins," of which only one historic U.S. example is known, are captured by a collar beam. Through purlins are further categorized as trenched, back, or clasped; butt purlins are classified as threaded, tenoned, and/or[clarification needed] staggered.


Common purlins in wood construction
Common purlins in wood construction, also called a "major-rafter minor-purlin system". Common purlins are typically "trenched through" the top sides (backs) of principal rafters and carry vertical roof sheathing (The key to identifying this type of roof system).

I love this thread. I hope I'm going to get the right answer here.
My 15 bedroom self con is completed and I need estimate for woods
to roof it including woods for the ceiling. I am going for PVC.

The last time I visited, here is the structure in the pics;

Please can someone help me out with the roofing estimate?

Below is what a Carpenter gave but to me it seems outrageous;

3x3 x12ft = 47 pcs
2x4 x18ft = 110 pcs
2x4 x12ft = 264 pcs
2x2 x12ft hard = 300 pcs
1x9 x12ft = 36 pcs
Nogging (I believe it's 2x2 for ceiling) = 435 pcs
PVC = 32 Bundles
Loar Angle (yet to know what it is..) = 80 pcs
4" nail = 2 bags
32 nail= 1 and 1/2 bags

Can any one here give me another estimate because I don't know whether
I am building a Cathedral here. I might decide to give it out lol!
