‘Hot Topping’: both exfoliated & crude vermiculite used ‘hot topping’ in the steel industry.


Vermiculite concrete roof deck systems allow architects, engineers and contractors versatility in design, high performance and reasonable cost. These systems will use a lightweight concrete consisting of Portland cement, water and vermiculite concrete aggregate. It is recommended that all vermiculite roof deck systems be applied by an applicator familiar with using and applying lightweight vermiculite concrete


Vermiculite concrete has excellent insulating properties. Three inches of vermiculite concrete is equivalent to 1 1/2″ of rigid board insulation laid over steel decks. One inch of vermiculite concrete is equal in insulating value to 20 inches of regular concrete.


Lightweight When compared with structural grade concrete, vermiculite concrete is 15% of the weight. This results in considerable savings from the footings thru the structural steel.


Vermiculite insulating concrete is easily placed by modern specially designed pumping equipment. Up to 25,000 square feet can readily be placed in one day.


The fireproofing characteristics of vermiculite concrete are recognized nationwide by insurance companies, state rating bureaus and local building officials. Underwriters’ Laboratories have assigned up to 4-Hour ratings to systems that employed vermiculite as one of the components.


Slope to drain systems employing vermiculite concrete and polystyrene vent board provide an economical solution to existing flat roofs with damage due to ponding of water.


Vermiculite concrete can be applied over a variety of bases, allowing architects and engineers ample flexibility in their design criteria. The thickness of the concrete can be varied to permit necessary slope to drain


Vermiculite concrete is suitable for installation over most structurally sound roofing systems with structural decks of concrete, metal, or wood. Care must be taken to properly vent decks poured over impervious materials.
