Every published DragonBoard assemblies, with the framing type, the rating, the span, the panel role, and the number of ceiling gypsum layers each design requires. If your condition is not here, tell us and we will give you a straight answer about whether we can cover it.
Framing type, rating, span, panel role and the number of ceiling gypsum layers each design requires. Wood framing sorts first.
The published design number. This is what belongs in the specification and what the authority having jurisdiction reviews.
The number of layers of gypsum board the design requires on the ceiling below. This runs the entire ceiling plane on every level, so it is a real line item on a repeating floor plate. We publish it rather than bury it.
A full assembly test has been performed and the design is published by UL with the panel named in it.
A testing laboratory has issued a written professional opinion extending a tested assembly to a closely related condition. Engineering judgments are widely accepted, and some authorities having jurisdiction review them differently than a listing. We will tell you which one you are working with, every time. The judgment letter is available through design assist.
Request the judgment letterSend us the framing type, the required rating, and the span. If we have a qualifying design we will name it. If we do not, we will say so rather than send you a data sheet and let you find out during review. We also have assemblies in active testing, and we can tell you what is coming and when.
