Technology
Technical Data
Nano facade insulation is based on a modern coating technology whose properties are described through technical tests and defined material specifications. It combines a low layer thickness of approx. 1 mm with a targeted influence on heat transfer.
Material properties
The nano coating used is a water-based acrylic resin dispersion: UV-resistant and weatherproof, vapour-permeable (water vapour permeable), strongly adhesive on a wide range of substrates, and low-emission, suitable for both interior and exterior use. It permanently withstands weathering, UV radiation and chemical influences without losing colour or function.
Layer build-up
Primer (substrate-dependent), functional layer (nano coating), top coat. The total layer thickness is approx. 1 mm.
Specifications
- Water vapour permeability
- Overall system vapour-permeable (V2)
- Water absorption
- very low (approx. 0.07 kg/m²·h⁰·⁵)
- Adhesive tensile strength
- ≥ 1.0 MPa
- Fire behaviour
- B1 – flame retardant
- Consumption
- approx. 1.0–1.2 litres per m²
- Curing
- approx. 24 hours per layer
CE marking
The coating is CE-marked on the basis of the harmonised product standard EN 15824; the declared performances are set out in the manufacturer's declaration of performance (DoP).
For CE-marked construction products the German Institute for Building Technology (DIBt) does not issue a general building authority approval (Section 16c sentence 2 MBO); no additional national recognition is required. They may be used under the building regulations of the federal states provided the declared performances meet the requirements of the particular use (Section 16c sentence 1 MBO). This does not affect the assessment of the performance values for the individual building.
Application
Applied by roller, brush or airless spray equipment, recoatable after a few hours. The technical data describes the material properties of the coating — the actual effect in the building also depends on wall build-up, application and use. An individual assessment is therefore essential.
