| R-Values:
R-20 - Insulating forms only, by test
R-25 - Finished walls by calculation
To determine concrete volumes (Cubic Yards):
Height (feet) X Length (feet) X Thickness (inches)
X .0031 = Cubic Yards
Form Wall Thickness:
2" per side, continuous
Fire Rating: (Siliceous
Aggregate) by test, without insulation:
4" - 1 hour 6" - 3 hours 8" - 4 hours
STC (Sound Transmission Class):
STC 58 - 8" Concrete, forms and finish, by calculation
Finishing
Techniques:
Interior: Drywall applied directly
over insulation surface, attached with standard drywall screws into
exposed polypropylene forming ties.
Exterior:
Synthetic masonry, damproofing or waterproofing applied directly
onto insulation surface per manufacturer. Prefabricated finishes
are attached mechanically into exposed polypropylene forming ties
or to continuos furring strips with fasteners which are appropriate
for exterior use.
In buildings
where people normally work, reside or assemble polystyrene concrete
forms must be fully protected from the interior of the building
by fire resistant material such as 1/2 inch gypsum board (drywall)
or the equivalent. |
