Clay foam combines the advantages of a mineral insulation material with the simple, safe and clean processing of a conventional foam system.
Durable
Clay foam adheres well to mineral surfaces.
Vapor permeable
The Clay foam is open to vapour diffusion. It is capable of absorbing and releasing moisture, thereby helping to regulate the indoor climate.
Vapor permeability μ = 3
Fast
A single-family home can usually be insulated with clay foam within a day.
Insulating
The clay foam has an outstanding insulation performance of λN = 0.034 W/m•K (DIN EN 12667)
Economical
Core insulation with clay foam leads to massive savings in energy costs.
Non-combustible
With a content of 90% inorganic components, dried clay foam is non-combustible - without the use of additional flame retardants.
Material classification A2- s1,d0 (DIN EN 13501-1)
Cleanly processable
The water-based clay foam components can be easily transported and processed cleanly – without any dust or fibres.
Recyclable
During dismantling, clay foam can easily be deposited with construction waste or reused as substructure material.
Gentle facades
The fresh foam is injected into the cavity through small drilling holes.
Space-saving
The physical foaming with air creates a foam that exceeds the original volume by a factor of ten.
Safe
Clay foam consists of safe raw materials and is classified as a 'very low-emission building material' EC1 PLUS according to GEV-EMICODE® standards.
Water repellent
Clay foam is hydrophobic and does not absorb liquid water.
wlp = 0.36 kg/m² water absorption (DIN EN 12087)
Gap-filling
Clay foam has excellent flow properties and perfectly adapts to the contours within the cavity. The foam fully surrounds installations and tight areas, including mortar protrusions and anchors.
Clay foam is self-sealing: it seals small slits or cracks in the masonry, prevents draughts and makes time-consuming preparatory and follow-up work unnecessary.
Non-expanding
The foam does not expand further and does not create additional pressure.
Sound-absorbing
Ambient noise is noticeably reduced by the use of this open-cell foam insulation.
Rw = 14 dB sound insulation index (DIN EN ISO 10140-2)
