Comparison to ETICS

Nano facade insulation is a modern alternative to classic facade insulation such as external thermal insulation composite systems (ETICS). While conventional systems work mainly through material thickness, Nano facade insulation is based on specifically influencing heat transfer through its material structure.

Evolution of insulation: from the Stone Age brushwood and clay hut, through timber framing with straw insulation and mineral wool, to the modern ETICS facade with scaffolding and the thin nano coating applied by spraying — Millennia of building history at a glance: from the first shelter to modern facade insulation.

The key differences

Nano facade insulation: coating with approx. 1 mm layer thickness, no insulation boards required, direct application to existing facades, low structural effort.

Classic insulation (ETICS): insulation material thickness of approx. 10–20 cm, multi-layer build-up (boards, reinforcement, render), elaborate installation, adjustments to roof, windows and details required.

Areas of application compared

Area of application	Nano facade insulation	ETICS
Older buildings	very well suited	limited
Listed buildings	well suited	often not possible
New builds	suitable	standard solution
Complex facades	very well suited	elaborate

Benefits for older buildings and renovation

Nano facade insulation shows its strengths especially in existing buildings: the facade appearance is preserved, walls are not made thicker, window reveals stay unchanged, and it is suitable for listed buildings. In these areas, ETICS is often only usable to a limited extent.

Important context

Nano facade insulation does not replace classic insulation measures in every case. Depending on the building, it can be an alternative, a complement, or a specific solution for particular requirements.
