Lightweight Concrete Roof Decks

Lightweight roof pavers were invented to follow the natural slope of the roof and where an existing roof or new roof construction requires a lighter load.

Lightweight concrete roof decks.

Lightweight insulating concrete decks non structural low density lightweight insulating concrete lwic can be placed upon a variety of structural deck systems that have been designed to carry loads. Elastizell low density concrete roof decks. Elastizell low density insulating concrete is a mixture of portland cement water and elastizell pre formed foam. Cast with 1 of concrete laminated to a 1 1 2 of expanded polystyrene foam these pavers have the look and feel of a full weight paver yet weigh in at roughly half the load.

With structural lightweight concrete a mix of shale slate slag and clay are used and with this mix the aggregate is fully saturated prior to mixing. Cellucrete has established itself as the leader in the lightweight insulating concrete industry with a proven track record of high quality installations throughout the. Not only does the deck acts as a permanent formwork to the concrete but also provides adequate shear bond with the concrete. Since 1985 cellucrete corp has been applying lightweight insulating concrete for roof decks structural concrete engineered fill applications and floor fill installations.

Lightweight concrete roof decks insulating concrete roof deck systems by insul flow provide performance value whether your project involves a new roof or replacing a damaged one lightweight concrete contractor insul flow has a practical concrete roof deck system for your needs. Hard rocks with a low water absorption rate and weighs approximately 2403 kg m 3 150 lb cf. With standard structural concrete the aggregate used is sand and stone. Thereafter precast systems are commonly topside insulated below the roof cover using adhered insulation panels or cast in place lightweight insulating concrete.

However when a lightweight structural concrete lwsc roof deck is poured in place it uses significantly more water. Lwic can be placed atop any of the above mentioned concrete deck types or directly upon a properly supported corrugated steel. The normal weight concrete employs standard aggregates i e. The steel deck panels are embossed in a manner which when filled with concrete allows the elements of the construction to respond to load as a single unit.

Composite lightweight concrete floors according to en 1994 1 1 2005 composite slab is composed of profiled steel decking with an in situ reinforced concrete topping. An effective new and reroofing solution. Beneath the roof cover structural concrete roof decks are commonly topside insulated using adhered insulation panels or cast in place lightweight insulating concrete. Structural concrete composite deck a supported steel panel deck system filled with normal weight or structural lightweight concrete.

It does not contain any water absorbing expanded fillers and requires only one fourth the mix water of expanded aggregate insulating concretes.
