Lightweight Concrete Roofing System
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 the lwic systems are composed of either aggregate or cellular concrete.
Lightweight concrete roofing system. Profiles are a fraction of the weight of our conventional roof tiles and are perfect for re roof projects. The increase can also be attributed to the economic and environmental advantages that lightweight insulating concrete lwic provides in roof assemblies. Eaglelite is our lightweight fire safe roof tile that is available in some of our most established profiles and colors. Since 1985 cellucrete corp has been applying lightweight insulating concrete for roof decks structural concrete engineered fill applications and floor fill installations.
Cellucrete has established itself as the leader in the lightweight insulating concrete industry with a proven track record of high quality installations throughout the. The use of lightweight concrete as a roof decking and insulation system has expanded in the past five years. Our sub six profiles and our flat lightweight 720 lbs. It combines ardex technology with the addition of lightweight synthetic particles to create a deep fill that can be applied from a minimum of 3 4 up to any thickness.
This process provides fire protection prevents air infiltration and bonds the total insulation system to the substrate. The end result of the structural lightweight mix is a deck that can be 20 25 lighter than standard structural concrete. The reduced quantity of concrete and steel reinforcement offsets the marginally higher cost of lightweight concrete floor systems. Lightweight concrete floor provides more efficient strength to weight ratio in concrete floor systems when compared to other conventional concrete floor systems.
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. 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. The proper design of falls on a flat roof is an essential consideration in the overall drainage of the roof.
