Installation Best Practices

A full-scale truss bracing demo was an eye-catching feature of the BCMC 2017 show floor.

For decades, SBCA Jobsite Packages have helped component manufacturers (CMs) provide handling and installation guidance to their customers with every order. These pre-assembled packages of instruction documents, attached to truss deliveries in a zippered plastic bag, are now available in a digital format.

SBCA’s library of technical design and installation best practices has been expanded over the past year to help CMs navigate a wide array of code-related challenges in their markets.

How important is continuous lateral bracing in roof trusses? Is it detrimental to the roof integrity if it is missing?

I am looking for a 1-hour roof/ceiling assembly for wood truss construction. I would like to apply the drywall directly to the bottom of the truss and also have insulation for sound control. Is this possible without using channels and what UL number would I use?

How do I, as a truss manufacturer, adequately advise my customer against the dangers of 60 ft. and over truss span installations?

I have a 29 x 72 mobile office with a 2-foot deep wooden truss above the ceiling that a client is required to sprinkler. Is there any way to avoid sprinklering above the gypboard ceiling?

In RC 2601, is RC-1 Channel used?

We recently received bids on a school project, which referenced UL P523. This assembly used light-gauge steel trusses. We noted on the drawing that we could accept an alternate design using wood trusses in lieu of light-gauge steel framing, if the alternate design could meet the fire ratings.

I am looking for strongback bracing requirements for a 12 in. deep residential floor system with trusses in lengths up to 19 ft. Can the strongback bracing end at a truss without tying into an end wall? For instance, can three trusses of a type be tied together by strongbacks, then the next series of different trusses be tied together without having to be tied back to the previous type of trusses?
