0.14 W/(m²K) in-situ measured U-value*
Measured, not claimed

Insulation performance you can measure.

PScoat is a functional thin-film coating (approx. 0.5 mm) – not ordinary paint. In a continuous in-situ measurement with the Testo 635-2, around 42,000 readings were recorded overnight on a real historic solid-masonry wall, with U-values down to 0.14 W/(m²K).

* Value determined on the examined component under documented boundary conditions and derived from the in-situ measurement – not a building-authority design value and not generally transferable to other wall structures.

How it works

How Nano facade insulation works.

Three thin layers, one physical principle: heat is reflected at the surface, and heat conduction inside the material is significantly reduced by hollow ceramic nanospheres.

A hollow ceramic nanosphere shown in section among further spheres: heat radiation is reflected at the surface, while heat conduction takes a longer path around the cavities.

The system build-up

1
Substrate Masonry, concrete or render
2
Primer Adhesion promotion, substrate levelling
3
Functional layer Hollow ceramic nanospheres, larger share of the insulating effect
4
Top coat Hollow ceramic nanospheres as well, complementary insulating effect, UV and weather protection, can be tinted

Total layer thickness: approx. 1 mm instead of centimetre-thick insulation boards.

Stepped cross-section of the system build-up: substrate, primer, functional layer and top coat — cut-open hollow ceramic nanospheres are visible in both coating layers.

Two of three heat transfer modes specifically reduced

Heat transfers in three ways: radiation, conduction (heat transfer through materials) and convection (heat flow in gases/liquids). The coating specifically counters the first two — convection plays no role within a solid, closed material layer.

1. Radiant heat (reflection)

Radiant heat, such as heat from the sun, transfers without loss even through a vacuum. Most of this radiation is reflected directly at the surface before it can penetrate the substrate.

2. Conduction (heat transfer)

Conduction transfers heat through direct contact between neighbouring molecules. Inside the hollow ceramic nanospheres this continuous contact is missing — heat has to pass around every cavity and therefore takes a considerably longer path. These spheres are present in both the functional layer and the top coat.

The physics behind it is not new.

Three familiar applications side by side: a cut-open aerogel block with a fine pore structure, a glass pane with an extremely thin reflective coating, and an insulating glass unit with cavity and edge seal.
  1. 1
    Aerogel Very small pores can influence the heat transport of the enclosed gas.
  2. 2
    Solar control glass An extremely thin coating can reflect a large part of solar radiation.
  3. 3
    Insulating glass The overall effect arises from several components and mechanisms.

Nano facade insulation uses several of these effects within a very thin functional layer and top coat. What this achieves on a specific wall can be measured on the complete building element.

These comparisons show that the underlying physical principles are established. They say nothing about the magnitude of the effect — that is what the measurements are for.
