Lightweight Concrete Roof Slabs

Polystyrene lightweight concrete s density compression strength and thermal conductivity are similar to that of foam concrete.

Lightweight concrete roof slabs.

It is designed for efficient construction of gradient and thermal insulating layers of flat roofs. Lightweight concrete can also be applied as a topping slab over structural concrete decks. The design makes it cheaper. Light weight concrete slabs are available both with a raw and with a ground surface.

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. Boral has specially designed lightweight concrete using a non toxic treated polystyrene aggregate or by the use of cellular foam injection by specially trained applicators. Lightweight concrete is typically applied as composite slabs over vented metal decks that meet the requirements of astm a653 and are of the proper type and gauge to withstand the structural live and dead loads for the facility. They are used as load bearing or non load bearing elements in residential and commercial construction or as noise barriers on streets and railway lines.

Lightweight screeds and substrates. Our sub six profiles and our flat lightweight 720 lbs. The lwic systems are composed of either aggregate or cellular concrete. Light weight concrete slabs can be used universally.

Standard concrete as a density of around 2300kg m3 and lightweight concrete generally has. Profiles are a fraction of the weight of our conventional roof tiles and are perfect for re roof projects. Depending on local availability special lightweight aggregates may also be included in the design for enhanced strength capability. Dry screeds and dry fills.
