Five over one repeats the same floor plate four or five times. Whatever the floor system costs you in schedule, crew coordination, and structural weight, it costs you on every level. DragonBoard takes the pour off the deck.
The rating requirement and the framing change as you move up the building. So does the right panel.
This is the volume of the building and the core of what we do. One hour rated floor and ceiling assemblies on wood truss or dimensional lumber framing, with a structural magnesium oxide subfloor in place of a gypcrete topped wood deck. MAG X-24 where the truss framing opens to 24 inch on center. Structural Subfloor where framing stays at 16 inch on center and weight is the constraint.
Where the structural deck is already wood panel and the assembly needs a rating, InfernoBloc underlayment reaches a one hour rated assembly without a poured gypsum underlayment and without the trades that come with it.
Where the framing is cold formed steel, we hold one and two hour assemblies on steel joist framing, including a single layer ceiling option. Super Stud, a sibling brand, supplies the cold formed steel framing itself, so the floor and the framing can come from one relationship.
Nothing has to set before the next trade starts on that level.
The framing crew already on site installs the deck.
No hose runs, no wet trade above finished work.
Install proceeds in conditions that stop a pour.
No drying time before flooring.
At four pounds per square foot, a DragonBoard deck is roughly 60 to 70 percent lighter than a poured system across the same floor plate. On a five or six level building that difference accumulates through the framing, the columns, and the foundation. It is a decision made once at the floor system and returned everywhere below it.
Framing type, level count, required ratings, and spans. We will come back with the qualifying design numbers level by level and tell you plainly where we have coverage and where we do not.
