3. What is Low Density Insulating Concrete ?
Low Density Insulating (Cellular) Concrete (or often referred to as Lightweight Insulating Concrete – LWIC) is produced by adding preformed foam to a cement / water slurry
The air introduced via the foam, is a non-reactive filler that controls the cast density of the concrete
Density may be varied depending on requirements
The material is pumped into place and finished slope to drain

4. Elastizell Low Density Insulating Concrete Roof Decks provide:
Positive drainage
Wind uplift ratings and fire resistance
Sound attenuation
Permanent base for built-up and single ply roofing membrane systems
Seismic values

5. Production Process Foam Generator Foam Added to Slurry Material pumped

10. Elastizell Low Density Insulating Concrete Roof Decks
Elastizell can be cast over concrete (precast or cast-in-place), galvanized steel and wood deck substrates
When combined with EPS, Elastizell Low Density Insulating Concrete Roof Decks have advantages over other roofing systems

11. Elastizell Advantages:
Positive drainage – customized slope to drain
Fire resistance
Sound attenuation
Thermal insulation
Seismic
Permanent solid base for built-up systems or single ply membranes

12. Combine with EPS Insulation Board for Increased Insulation
High EPS (Expanded Polystyrene) insulation values (R = 4.0/inch)
Less dead weight – these systems typically weigh only 6-8 psf
Stair-stepped EPS board and top with Elastizell insulating concrete for slope-to-drain

13. Elastizell Roof Decks Are:
Permanent
Insulative
Nailable
Approved
Economical
Moisture resistant
Wind uplift resistant
Sloped to drain
Strong
Dimensionally Stable
Non-combustible

17. Wind Uplift Approvals FM – ratings from 1-60 to 1-540 UL – Class 90
FM Class I, Non-combustible
FM SH (Severe Hail) rated
Numerous Miami-Dade (FL) and Florida Building Code approvals with a variety of membrane types and manufacturers
for full list of approvals

18. Elastizell High Wind Uplift

19. Fire Rated Systems Over 60 UL fire rated listings
FM Class I fire classification
Non-combustible, even with EPS embedded in the system
Fire channel is eliminated by filling the flutes with Elastizell Low Density Insulating Concrete
for up to date fire rated systems
