Quad-Deck Joist and Deck Forming System
Frequently Asked Questions
- What is Quad-Deck?
Quad-Deck is a versatile forming system for suspended concrete floors and deck roofs. It provides superior heat and noise insulating qualities.
-
What
is Quad-Deck made of?
Quad-Deck panels are made of Expanded Polystyrene (EPS) and have integrated steel beams molded into the panel that create formwork for the support of concrete, reinforcement, and construction loads.
- What are the sizes of Quad-Deck?
Quad-Deck is available in 7 different thicknesses (7", 8", 9", 10",11", 12" and 12.5"), creating concrete beam depths of 5" to 10.5". It is custom cut at the factory to the lengths required for your building project.
- What is the R-value?
Depending on job requirements, Quad-Deck offers R-values ranging from R-16 to R-33.
- How far of a span can I build?
Quad-Deck can be used to achieve up to about 30 foot clear spans with low live loads and regular construction methods. For longer spans, other secondary structural support may be required; e.g. column-supported beams, slab bands, girders. Increased beam heights using additional EPS on the Quad-Deck and Post-Tensioning can also be used to extend the spans and/or live loads. Always remember, it is the Structural Engineer who will determine the thickness, allowable span and required reinforcing for any project. Quad-Lock has the tables that will conservatively suggest allowable spans.
-
How
is Quad-Deck braced?
Quad-Deck needs to be supported underneath with typical shoring. Shoring should not be further than 6 feet apart. The Structural Engineer or Shoring Engineer (often provided for free with shoring rentals) is responsible for the correct layout. The Quad-Deck acts as its own formwork so no plywood, etc. is required which makes Quad-Deck quick to install – saving on installation and stripping labour.
