Airtec Stone
The lightweight natural stone façade
Airtec Stone offers many design options for creating high-quality natural stone façades with numerous types of stone, different sizes and shaped units. Even large panels with an area of up to 7.7 m² can be hooked into the aluminium substructure without any visible fixing elements. The panels consist of a top layer of stone with a thickness of 5 to 10 millimetres on a lightweight concrete base panel not more than 19 millimetres thick, which makes them up to 60 per cent lighter than solid stone slabs. They can also be installed overhead using invisible fixings.
System | Ventilated curtain wall façade system with worked stone slabs on a lightweight concrete base |
Properties | Weather-resistant and frost-resistant; the flexible substructure offsets any unevenness in the substrate |
Fixing | Invisible fixing to aluminium substructure |
Finishes / Appearance | Types of stone: Limestone and sandstone, slate, granite (polished, ground); all other types of stone and finishes on request |
Sizes | Panel size up to 7.7 m², depending on size of unhewn stone |
Overhead | Up to 5.26 m² (max. 4.05 x 1.30 m) overhead application with AbZ (general building inspectorate approval) |
Approval | Z - 10.3-817 |
Thermal protection | Mineral-wool insulation (TCG 032 and 035) |
Reaction to fire | Fire-resistant, construction materials class B1 to DIN 4102-1 A2, s1,d0 in accordance with EN13501 possible |
Impact resistance | E5 classification, DIN 14019, maximum resistance to mechanical influences |
Individual architectural elements
Giving shape to your ideas
Modern architectural façades feature three-dimensional shapes. Such designs are easily realised using our architectural elements made from natural stone: shaped units of storey-height in lengths of up to 3.50 m.
The special material properties of the composite natural stone panel make it possible to create shaped units with the same appearance and a much reduced self-weight. As a result, three-dimensional preformed units such as corners, angles or U-sections can be produced to achieve a monolithic effect. This involves first mitring the composite panels and securing them without a visible joint, using a bonded press fit. Cantilever panels up to 400 mm in length can be attached to an anchoring panel. This method also allows the façades of listed buildings to be faithfully restored.

Suspended natural-stone ceilings are not a problem
Another special feature of the Airtec Stone VCW façade system is that it can be installed overhead. While traditional, solid stone slabs very soon reach their structural economic limits because of their own heavy weight and elaborate fixing methods, Airtec Stone panels can be used to clad suspended ceilings in ways that are structurally safe and comparatively cost-effective. With Airtec Stone you really can use natural stone wherever you want!
