Lightweight Concrete Roof Insulation Details

Zic is used in new construction applications over slotted galvanized metal decking.

Lightweight concrete roof insulation details.

Lightweight insulating concrete includes the application of expanded polystyrene eps insulation boards. This section specifies insulating concrete placed on a prepared structural deck and integral insulating board composite construction. Siplast lightweight insulating concrete is available in four mix designs. Zic nvs insulcel and zonocel.

With and elastizell system only the roofing membrane need be replaced. Lwic roof membrane performance. The lightweight insulated concrete system lwic utilizes the sarnafil g 410 feltback roof membrane designed specifically for adhered applications bonded to the concrete using sarnacol 2121 water based membrane adhesive. This process provides fire protection prevents air infiltration and bonds the total insulation system to the substrate.

The eps insulation must have a minimum density of 1 pound per cubic foot and have keyholes properly spaced throughout the boards for concrete flow through the boards.

It s used in the form of boards in. 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.

Air entrainment and water. Lightweight insulating concrete systems. Elastizell low density insulating concrete roof decks are not damaged by water and the encapsulated eps board the heart of the insulating system is completely protected. This combination creates a durable roof system that also has excellent wind uplift values.

Expanded polysterene eps used in lwic is the preferred material. Each design encapsulates the insulation board in insulating concrete. The lighter weight concretes 50 pounds per cubic foot or less which are the most effective as insulation can be used in combination with other materials in wall roof and floor systems where they are the most advantageous in reducing heating and cooling costs. Lwic have been in use for over 60 years.

Lightweight insulating concrete insulation. Since 1985 cellucrete corp has been applying lightweight insulating concrete for roof decks structural concrete engineered fill applications and floor fill installations. The standard 1 6 mix requires a minimum 2 inch thickness of zic over the top of the insulperm insulation board. The standard zic mix is a 1 6 ratio of portland cement volume to zic concrete aggregate volume.
