Lightweight Insulating Concrete Roof Deck

Siplast lightweight insulating concrete is available in four mix designs.

Lightweight insulating concrete roof deck.

Lightweight insulated concrete also known as lwic is a material intended for use as an insulation and substrate for support and attachment of roofing membranes on slope roofs. Each design encapsulates the insulation board in insulating concrete. Lightweight insulating concrete roof decks are high performance roof insulation systems that reduce roof maintenance and replacement costs. Beneath the roof cover structural concrete roof decks are commonly topside insulated using adhered insulation panels or cast in place lightweight insulating concrete.

Trust the experts in lightweight insulating concrete roof deck systems discover an ideal roof insulation system. The four designs represent a range of compressive and tensile strengths allowing a choice of system based on substrate and specific project circumstances. 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. Lightweight insulating concrete lwic is a high performance insulation system with mix designs consisting of portland cement fine lightweight expanded aggregates such as vermiculite and perlite or preformed foams that encapsulate.

Serd is a specialty subcontractor providing lightweight insulating concrete roof decks metal decking tectum acoustical roof deck panels engineered fills and material sales. Cellucrete has established itself as the leader in the lightweight insulating concrete industry with a proven track record of high quality installations throughout the southeast united states. The most common use of vermiculite lightweight concrete is for light structural roof decks and for insulation fill over metal decking and structural concrete. The largest single use for lwic is as a roofing base and thermal insulation for industrial and commercial buildings with low slope roofs.

The lighter the concrete the better lower the k factor. Structural concrete composite deck a supported steel panel deck system filled with normal weight or structural lightweight concrete. Vermiculite for roof decks can be placed over various kinds of form boards fiber fiberglass acoustical and asbestos cement. Zic nvs insulcel and zonocel.

Lightweight insulating concrete lwic is batched on site and used to encapsulate expanded polystyrene insulation to provide permanent roof insulation and slope to drain. The system can be placed over galvanized steel decking and over pre cast or cast in place concrete. Elastizell requires only one fourth the mix water of other insulating concretes. The lwic systems are composed of either aggregate or cellular concrete.
