Product Description

The Superform Insulated Concrete Forming System is a series of hollow blocks that consist of two basic components. Firstly, rigid expanded polystyrene (EPS) panels, or sheets, shape-molded to specific dimensions and configurations, and secondly, injected polystyrene ties, or webs, are molded into the rigid EPS panels to result in what looks like a Lego block with the center portion removed.

The blocks are produced in such a way as to allow for a staggered, interlocking stacking pattern. This is strong enough to withstand the hydrostatic forces of wet concrete as it is poured into the void between the panels of EPS, producing a monolithic concrete wall that is 6 7/8” thick throughout its height.

The expanded polystyrene is treated with a flame-resistant additive (which makes it Type 2 EPS) and complies with CAN/CGSB-51.20-M87.

The 2 5/8” of rigid EPS on each side of the wall provides a net thermal insulating value of R28, in accordance with ASTM C236-89.

A major advantage of the Superform wall is the fire resistance rating of min. 3 hours. Sound transmission rating 55 (STC)

Concept

The Superform system is intended to replace conventionally poured concrete foundation walls in residential and light commercial construction. The rigid EPS provides both the form for the retention of wet concrete, and the thermal insulation for the exterior wall. The EPS also provides superior sound barrier insulation for interior party walls. The plastic ties in the blocks (which are recessed slightly to prevent thermal bridging) are a three-fold unit.

  • Firstly, they provide the “tie” member of the forms… that is; they hold the two panels of EPS the correct distance apart while concrete is being poured.
  • Secondly, they allow for proper placement of reinforcing bar by way of three slotted pockets in each tie into which the rebar is snapped.
  • Thirdly, the “T” shaped portion at each end of the member to which inside and outside finishes is attached.

Thus, the Superform wall system accomplishes forming, framing and insulating in one step, providing a finished wall far superior to any other framing method.

Materials used:

All materials used in the manufacturing process of the Superform units comply with all applicable American and Canadian building codes, which govern the use of building materials intended for use in occupied dwellings.

The two basic components are flame-retardant modified expanded polystyrene (EPS), and raw beaded polypropylene, both of which carry current validation and certification.

The finished blocks are free of CFC’s, HFC’s, HCFC’s, and formaldehyde, and develop fewer toxins when burned than many common household materials. According to all applicable building requirements, the Superform blocks are completely acceptable for the construction industry.

According to the National Research Council of Canada, expanded polystyrene has a flash-ignition temperature of 340 degrees Celsius (655 F), while pine lumber has a flash ignition temperature of 224 degrees Celsius (400 F).

EPS closed cell rigid foam plastic insulation (CAN/ULC – S701-97) complies with Underwriters Laboratories of Canada CAN/ULC – S102.2M.

A quote from the National Research Council in Ottawa regarding the results of a flammability test done on expanded polystyrene: “The maximum toxicity index obtained from the combustion of polystyrene was of the same order as that from wood.”

Recommended concrete design = 25mpa, 6” slump, maximum aggregate size = 3/4”.

- Engineers may take into account - According to the Portland Cement Association, concrete poured and cured inside an insulating concrete form gains approximately 30% more strength than the same concrete poured in wood forms.
