Elastizell Composite Insulating Roof Deck Systems: Elastizell is 100% Portland Cement and contains no water absorbing expanded fillers. Elastizell requires only ¼ the mix water of expanded insulating concretes. A common misconception is that all insulating concretes have high water content but in reality, Elastizell does not. Elastizell’s workability is obtained from discrete air-cells, not from excessive water.

• Elastizell composite insulating roof deck systems provide:
  • Positive drainage
  • Fire resistance
  • Wind uplift ratings
  • Seismic values
  • Thermal insulation
  • Sound attenuation
• A solid base for built-up and single-ply roofing membranes for both new construction and reroofing applications.
• Elastizell can be cast over concrete (precast or cast-in-place), galvanized steel and wood deck substrates.

Adding a predetermined volume of Elastizell preformed foam to a cement/water slurry produces Elastizell concrete. Elastizell insulating concrete roof decks are cast according to the density and strength requirements for the specific installation.
Elastizell is approved by all major roofing manufacturers and they have single source warranties available!

Siplast, a major roofing manufacturer, has single source warranties available.
Siplast NVS (Non-Vented Substrate) System has been engineered for use over concrete substrates, reroofing and where appropriate, recover applications. In these applications, NVS Insulating Concrete, combined with Insulperm Insulation Board provides positive slope-to-drain over flat or irregular substrates.

• An advantage of using this NVS System is that it is more economical than installing tapered, rigid board systems or sloping the structural concrete. The NVS system can also eliminate the need for costly tear-off and simplify surface preparation depending on the condition of the existing roof system.
• The Siplast NVS System is a 1:3.5 ratio of Portland cement volume to patented NVS Concrete Aggregate volume. It is used over non-venting substrates such as structural concrete and because of its higher-compressive and tensile strengths, NVS requires only a 1-inch minimum thickness over the top of the Insulperm Insulation Board.

Siplast Insulcel System is designed for application over impervious substrates. Insulcel Insulating Concrete combines Insulcel-PB pregenerated cellular foam with a Portland cement/water slurry to produce an economical cellular concrete. Insulcel can be installed over non-slotted or slotted-galvanized corrugated metal decks, structural concrete substrates and, where appropriate, over existing roofs in recover applications. Insulcel is not intended for use in extremely hot, dry climates.

• Insulcel’s excellent fire resistance properties make it cost effective versus the more expensive alternative of adding a fireproof coating to the deck’s underside, as required by most systems incorporating conventional rigid insulation board.
• The Insulcel System is appropriate for jobs located in climates that are conducive to proper curing of cellular concrete. Insulcel Insulating Concrete is placed at a minimum 2-inch thickness over the top of the Insulperm Insulation Board.

Siplast ZIC System has been successfully installed for many years over galvanized slotted corrugated metal deck where insulation and slope are required in a fully fire rated construction. By design, Siplast Lt. Wt. Insulating concrete Systems encapsulate Insulperm Insulation Board in insulating concrete. Specific insulation values, from low to very high, can be achieved to meet design requirements simply through the adjustment of the Insulperm thickness. Because Insulperm can be installed in stair-step fashion, slope-to-drain is much easier to achieve than creating slope with complicated tapered rigid board insulation systems. Given its inherent fire resistant quality, ZIC remains an economical alternative to the expensive process of fireproofing necessary for other insulation systems to meet the same fire ratings achieved by the Siplast ZIC System.

• The standard Siplast ZIC System is a 1:6 ratio of Portland cement volume to ZIC aggregate volume. ZIC is used in new construction applications over slotted galvanized metal decking. The standard 1:6 (cement to aggregate ratio) system requires a minimum 2-inch thickness of ZIC over the top of the Insulperm Insulation Board.

Perlite is a mixed glassy silicate of volcanic origin. Its unique internal structure consists of numerous tiny closed air cells surrounded by a large exterior irregular surface. Expanded Perlite is ultra-lightweight, inert, sterile, permanent, incombustible, asbestos-free, non-toxic, rot and vermin proof and has a neutral pH. Its internal closed air-cell structure resists thermal transmission giving Perlite its inherent insulating properties. Its extremely large, open surface area offers benefits in other areas such as horticulture and filtration.

Perlite sold to the Construction market is under the trade name RedcoLite. RecoLite perlite insulating concrete can be used with expanded polystyrene board to achieve two-hour fire-resistive and non fire-resistive roof decks. The RedcoLite Concrete Aggregate is mixed with Portland cement, air entrainment, and water. Wet densities should be approximately 40 pounds per cubic foot and dry densities approximately 27 pounds per cubic foot with a minimum compressive strength of 140 PSI.
