Advantages of Elastizell JLE
Lightweight Insulating Concrete Roof Decks

• Strong, permanent, economical, and lasts for the life of the building
• Positive slope-to-drain eliminates drainage problems and standing water
• Closed Cell nature results in relatively impermeable concrete deck
• Improved thermal insulation values when combined with Zell-Board EPS insulation board
• Eliminates roof insulation tear-offs and related disposal to landfill
• Improved fire resistance, non-combustible
• Tested seismic values

Cellular Systems

• 100% Portland Cement and Elastizell preformed foam
• Elastizell requires only one quarter the water of expanded aggregate insulating concretes
• Obtains it’s workability from discrete air cells
• Zell-Crete Fiber is added for improved tensile strength roof deck
• Positive drainage achieved by combining stair-stepped Zell-Board EPS insulation and on-site custom sloping of Elastizell's relatively impervious concrete to the roof drain
• Zell-Board EPS Insulation embedded in concrete for protected, permanent R-value
• For use with adhered roof membrane base plies or with mechanically attached base sheets

Hybrid Systems

• Combine Elastizell JLE closed cell lightweight concrete and expanded aggregate concrete
• Expanded aggregate additive (vermiculite) retains enough water to improve hydration of the insulating concrete mixture and acts as a rheological modifier for sloped applications
• Zell-Crete Fiber is added for improved tensile strength roof deck
• Positive drainage achieved by combining stair-stepped Zell-Board EPS insulation and on-site custom sloping of Elastizell's relatively impervious concrete to the roof drain
• Zell-Board EPS Insulation embedded in concrete for protected, permanent R-value
• For use with mechanically attached vented base sheets
