Lightweight Concrete Roof Fill

The most common use of vermiculite lightweight concrete is for light structural roof decks and for insulation fill over metal decking and structural concrete.

Lightweight concrete roof fill.

Siplast lightweight insulating concrete is available in four mix designs. Polystyrene lightweight concrete s density compression strength and thermal conductivity are similar to that of foam concrete. Insulated concrete roofing systems low density insulating concrete roof decks are monolithic composite systems cast over galvanized metal decks structural concrete wood decks or existing roof systems. Two of the biggest benefits of utilizing lightweight insulating concrete is its high energy efficiency and the ability to control the product to create slopes to drain.

The most popular product for interior surfaces is lightweight gypsum concrete gypcrete. In many cases the use of lightweight concrete versus traditional rigid roofing insulation you will save both time and money. It is designed for efficient construction of gradient and thermal insulating layers of flat 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.

Siplast lightweight insulating concrete systems combine the unique properties of lightweight insulating concrete and insulperm premium expanded polystyrene foam insulation board. Vermiculite for roof decks can be placed over various kinds of form boards fiber fiberglass acoustical and asbestos cement as well as over paper back wire lath. Since 1985 cellucrete corp has been applying lightweight insulating concrete for roof decks structural concrete engineered fill applications and floor fill installations. Geofoam is a lightweight geosynthetic fill material used as an alternative to various fill materials as a soil stabilizer and in various engineered applications.

The lwic systems are composed of either aggregate or cellular concrete. Elastizell has a national network of qualified and approved applicators that have been trained in proper installation techniques. Lightweight concrete lightweight concrete can be applied on exterior and interior surfaces. For exterior surfaces such as decks balconies or roof pads cement based lightweight concrete is the best choice.
