Airium^® roofing and attic systems

Main uses

In flat roofs, Airium^® can be used as an insulating slope (with a density typically of 400 kg/m3). It allows to build and to insulate at the same time and is especially valuable in emerging countries. Airium^® is produced out of local ingredients and typically replaces both the insulation material (Polystyrene or Cork for example) and the concrete slope with a layer of 10 to 15 cm. In case of more demanding regulations, Airium^® can replace the screed to slope with a lighter alternative while still being combined with other insulation materials.

Main benefits

Image	For developers, investors and end-users, 12 cm of Airium® 400: Yields up to 48% of energy savings in a typical house in Mexico or Algiers for instance, or up to a 5°C celsius difference felt in a house if no cooling is used.  Provides a continuous insulation with no thermal bridges and no loss of performance over time Provides optimal fire resistance Helps to reduce the deadload by a factor of 3 to 8 depending on the comparison made, which enables both engineers to optimize structural design for new projects and owners to easily go for renovation works.
Image	For contractors and applicators, Airium® simplifies life on site: less steps to complete the work as Airium fulfils the insulation and the sloping functions at the same time, no storage, no cutting and placing of boards: Airium® is pumped from the ground (up to 100 meters). A 1 to 2.5% slope is easy to shape with Airium®, though the applicator must be trained and familiar with the technique and the accessories (tripods or laser, metal bars, joints).
Image	For the planet, Airium® is mineral and easy to recycle along with the slab with no separation phase. By lowering the deadload in horizontal applications, Airium® also contributes to lowering the CO2 intensity per each square meter built.

How it works

Airium^® can be brought to site and pumped to your floor by different methods: with an integrated and automatic Airium^® truck, with a pump producing the mineral foam on site and fed with a premix in bags or in a silo, or with a pump receiving a specially made slurry from one of our ready-mix trucks. Holcim works hand in hand with application companies to deliver the best end-result. Airium^® typically sets in about 6 hours and can be walked upon after 24 hours (depends on local conditions). It requires a minimum drying time of about 1 day per centimetre before being covered with Waterproofing or a final layer. Any type of liquid applied waterproofing or bituminous membrane is compatible with an Airium^® with a density above 400 kg/m3.

Typical systems

Main uses

Airium^® is poured into attics on-site with a density and an insulating power adapted to the accessibility needs of the attics (50 to 180 kgs/m3).
