Lightweight Concrete Roofing System

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.

Lightweight concrete roofing system.

The use of lightweight concrete as a roof decking and insulation system has expanded in the past five years. Since 1985 cellucrete corp has been applying lightweight insulating concrete for roof decks structural concrete engineered fill applications and floor fill installations. This process provides fire protection prevents air infiltration and bonds the total insulation system to the substrate. 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.

The end result of the structural lightweight mix is a deck that can be 20 25 lighter than standard structural concrete. The proper design of falls on a flat roof is an essential consideration in the overall drainage of the roof. Profiles are a fraction of the weight of our conventional roof tiles and are perfect for re roof projects. Lightweight concrete floor provides more efficient strength to weight ratio in concrete floor systems when compared to other conventional concrete floor systems.

Increased usage can be attributed to the recent industry wide insulation shortages and delamination deficiencies. 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. Unlike rigid board siplast lightweight insulating concrete is reroofable and therefore a truly sustainable insulation solution.

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. To be effective it is essential to clear surface water as rapidly as possible from the flat roof to. This combination creates a durable roof system that also has excellent wind. The reduced quantity of concrete and steel reinforcement offsets the marginally higher cost of lightweight concrete floor systems.

These floors are constructed for different purposes but the reduction of dead loads on the structure is. Falls create flow paths to direct the drainage of rain water away from the roof to suitable discharge points. Eaglelite is our lightweight fire safe roof tile that is available in some of our most established profiles and colors. The ardex lw system is a lightweight fill system for existing indoor concrete slabs where the addition of dead load to the structure is a concern.

The largest single use for lwic is as a roofing base and thermal insulation for industrial and commercial buildings with low slope roofs. Our sub six profiles and our flat lightweight 720 lbs. The increase can also be attributed to the economic and environmental advantages that lightweight insulating concrete lwic provides in roof assemblies.
