The ELASTIZELL Advantage

= ELASTIZELL

OVER PRECAST OR STRUCTURAL CONCRETEElastizell Roof Decks are an excellent composite insulation system over precast and cast-in-place concrete. Since bottom-side venting provisions are difficult, perimeter venting should be considered at the flashing/counter flashing detail.

OVER GALVANIZED STEEL DECKSElastizell Roof Decks do not require the slotted steel decks demanded by wet aggregate concretes. Elastizell may be cast over either slotted or non-slotted steel decks according to local conditions. Specify Elastizell over G-60 or G-90 galvanized steel centering since painted steel deck is unsuitable for the direct application of any concrete.

For more than 50 years, the Elastizell Corporation of America has researched, developed, tested and improved the Elastizell Roof Deck System.

Elastizell Roof Decks have numerous wind uplift, fire and seismic ratings with both mechanically fastened, built-up roofing systems and fully adhered single ply membranes.

Major roofing manufacturers accept Elastizell Roof Decks with their warranted membranes.

Advantages of Elastizell• VERSATILE

Elastizell Roof Decks can be placed over precast or cast-in-place concrete, as well as galvanized (G-60 or G-90) steel decking. EPS insulation board increases R-values and reduces dead load, with system weights as low as 8 to 9 psf.

• RE-ROOFABILITY & NEW CONSTRUCTION Elastizell Roof Decks encapsulates EPS board within the system. The EPS board is bonded to the deck in new construction or to the existing deck in re-roofing appli-cations. When combined with EPS insulation, Elastizell Roof Decks provide a solid base for roofing membranes with custom slope-to-drain capability. The EPS insula-tion is protected within the system for a permanent LTTR (Long Term Thermal Resistance).

• SPEED Roofing may begin when the Elastizell Roof Deck can withstand foot traffic – typically two to three days after the deck is cast. The Elastizell Roof Deck should not be left exposed for longer than five to seven days, especially in dry climates. Crazing or cracking of the surface of the deck is not detrimental to the roofing system.

ELASTIZELL ADVANTAGES

• PERMANENT Elastizell Roof Decks completely encapsulate the EPS insulation board within the system. When re-roofing, only the membrane needs to be replaced.

• POSITIVE DRAINAGE Elastizell Roof Decks provide positive drainage in both new construction and re-roofing applications. Positive drainage patterns are achieved by combining a stair-stepped EPS insulation board with custom sloping of the Elastizell low density insulating concrete over the EPS board.

• FIRE RATINGS/NON-COMBUSTIBLE Elastizell Roof Decks have numerous fire ratings.These assemblies are non-combustible and do not require fire-proofing of the underside of the steel deck or a thermal barrier that is necessary with rigid board systems.The flutes of the metal deck are filled, eliminating the fire channel. See the back page for a listing of UL fire ratings.

• EXCELLENT WIND UPLIFT Elastizell Roof Decks perform as an air retarder providing excellent wind uplift performance. It bonds the EPS board to the structural deck, filling depressions and deck flutes. Elastizell Roof Decks have numerous UL, FM, and Miami-Dade County wind uplift ratings. See the back page for web links to these approvals.

• CONSTRUCTABILITY Flat decks are simpler to design and easier to construct than a sloped structure. Installation of HVAC components is easier with a flat deck structure. Elastizell Roof Decks provide a positive slope-to-drain system over flat decks, and are less expensive and time consuming than sloped rigid insulation board systems.

RE-ROOFING & SUSTAINABILITY

ProblemInsulation board systems typically require total tear-off in re-roofing applications. This is because the board has lost its strength and insulation value. Total tear-off is risky and can pose a threat to the building’s interior. A great deal of debris must be hauled to landfills – a costly operation which is time consuming and environ-mentally unacceptable.

Two inches of Elastizell low density insulating concrete adds 7 to 9 psf to the structure. Two inches of ponded water adds 10 psf dead load.

DiscussionA major advantage of the Elastizell re-roofing system is that it may be applied directly over the existing roof to correct drainage. The addition of EPS insulation board encapsulated within the Elastizell provides increased thermal insulation and a permanent, solid base for the final roofing membrane system. If portions of the existing insulation are wet or deteriorated, they should be replaced. If the old roof remains in place, the mess, time, and expense of tear-off are avoided.

STEP BY STEP RE-ROOFING PROCEDURE: 1. Check Existing Structure – Analyze the existing system for

load carrying capability.

2. Remove Loose Gravel – All loose gravel must be removed from the roof deck.

3. Cast the Elastizell Roof Deck – EPS insulation board is bonded to the deck as the Elastizell deck is cast, slope-to-drain.

4. Apply New Membrane – The roofing membrane is installed according to manufacturer’s specifications.

5. Perimeter Venting – Perimeter Venting is provided at the flashing/counter flashing detail, whenever possible.

Elastizell and LEEDElastizell Low Density Insulating Concrete Roof Decks have been used on many LEED certified projects. Elastizell Roof Decks assist with a number of LEED points in several sections of the LEED Rating system. Please see our website at www.elastizell.com/LEED for further details.

• Elastizell Roof Decks are accepted as a “Green” product by BuildingGreen, Inc., publishers of Environmental Building News, Green Building Advisor, and GreenSpec.

• Elastizell Roof Decks reduce energy load requirements, and facilitate renovations by resloping and increasing R-values.

• Elastizell Roof Decks are a durable, sustainable, and low-maintenance system. Due to all these features, Elastizell Roof Decks are listed in the GreenSpec Directory.

• Elastizell Roof Decks help reduce overall energy consumption by providing permanent insulation that does not suffer from the thermal drift characteristics associated with rigid board insulation.

• Elastizell Roof Decks provide a heat sink beneath the roofing membrane, which reduces thermal shock from solar heat followed by cooling at night or by rain. The reduction in thermal shock lengthens the life of the roofing membrane.
