Find out more about kingspan insulation products which are suitable to insulate cool concrete deck flat roofs. To insulate a flat roof with a concrete deck we recommend a warm deck construction method where the vapour control layer is sandwiched between the concrete deck and a layer of rigid pir insulation boards. The insulation will quickly become saturated with water and cease to be effective.

In fact insulation from the inside will inevitably lead to the formation of condensation caused by the humidity present inside the building. This method eliminates the need for ventilation and the risk of condensation whilst providing superior thermal performance to cold deck. Insulating concrete is made with special lightweight aggregates meeting astm specifications c332 or made by using preformed or formed in place foam with cement cement sand mortar and also with lightweight aggregates. The largest single use for lwic is as a roofing base and thermal insulation for industrial and commercial buildings with low slope roofs.

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 supports will rot if they are made of wood or rust if they are of reinforced concrete. The amount of insulation required with the specific structural deck will determine the.
