Four properties set the coating apart from classic insulation systems: thermal conductivity, U-value, surface temperature and vapour permeability. What each one means for your building is explained below.
Around 1 mm already achieves what a classic ETICS build-up needs about 15–20 cm of polystyrene for.
PScoat doesn't change your house — it blocks heat transfer at the surface.
The component's resistance is increased by adding extra insulation thickness.
PScoat changes heat transfer at the external surface — and with it, the heat path.
Indoor air transfers heat to the wall surface. This transfer has its own thermal resistance, described as Rsi.
Heat then flows through the wall material. Its resistance depends, among other things, on λ and the material thickness.
Finally, heat has to pass from the external surface to the outside environment. This portion is described as Rse.
First, we look purely at the 10 cm thick concrete layer.
This only covers conduction through the material itself. The heat transfers at both surfaces are still missing.
Now we also factor in the heat transfers at the internal and external surfaces.
In this simplified example, the surface resistances contribute significantly to the total thermal resistance.
The U-value describes the entire heat path: from the room, across the internal surface, through the component, across the external surface, to the outside environment.
Simplified:
In standardised U-value calculations, the actual heat transfer conditions can't be fully recalculated for every building, every hour, every wind speed, every surface temperature and every radiation environment.
That's why building physics uses defined reference conditions and standardised surface resistances for the standard calculation.
This standard sets out methods for calculating the thermal resistance and thermal transmittance of building components, using standardised boundary conditions and surface resistances.
The commonly used value Rse = 0.04 m²K/W is therefore a normative reference figure for the standard calculation – not a universal law of nature that stays exactly the same under all real outdoor conditions.
When the thermal properties of an external surface change, it's not just an extra layer of material. The surface's thermal boundary conditions relative to air, radiation and solar radiation can change too.
So the decisive question isn't just: “How thick is the layer?” It's also: “How does the entire heat path change?”
That's been standard for 30 years.
Modern thermal glazing uses what are known as low-E coatings.
These ultra-thin, virtually invisible layers change the thermal properties of the glass surface, reducing long-wave thermal radiation exchange in particular.
As a result, the U-value of the entire window improves by around 50% – even though the coating itself is extremely thin.
Technical background: The U.S. Department of Energy explicitly describes low-E coatings as a measure for reducing the U-factor. U.S. Department of Energy – Low-E and window performance

The decisive question isn't whether a thin coating could theoretically work. What matters is what's actually measured on the real component.
Measured on the real component over several hours of continuous monitoring – not a single snapshot.
Original measurement data: U-value, wall temperature, indoor air temperature and outdoor air temperature over the entire measurement period.
The U-value was determined on the real component over an extended period. The measurement data shows the calculated U-value settling into a low range for a sustained period after the initial settling phase.
So we're looking not just at a single temperature value, but at the progression of heat transfer over time under real conditions.
PScoat hasn't run measurements like this just once. The effect has been repeatedly examined and reproduced on different buildings and component structures.
The U-value measured earlier on the real building also shows up in the thermal image of the façade.
The heated building surfaces stand out clearly against the cooler surroundings in the thermal image.
After coating, the façade area that previously stood out clearly is far less pronounced in the thermal image.
Three details are enough to work out the material required. Add the recommendation to the order below with a single click.
This requirement is a guide value for a smooth substrate. Texture, absorbency and application method change it; it only becomes binding once tested on a sample area on the original substrate.
Which level fits depends on what the building needs to achieve. The first three include the material for the complete build-up; the fourth also includes application by a specialist contractor. With a U-value guarantee on every package level.

The thermal effect of PScoat has been studied under controlled conditions and on real buildings. That's why we go one step further: we tie our performance to a measurable result on the treated component.
What matters is what's actually achieved on your building. The energy-saving guarantee reduces your risk and makes the promised thermal effect verifiable.
We look at the starting situation and the existing wall structure. What always matters is the specific component – not a theoretical sample structure.
The coating is applied according to the chosen system and its intended use.
On request, the thermal effect can be verified through a documented U-value measurement on the specific component.

A residential building before and after coating, captured with a thermal imaging camera.
Before: high heating output and still no satisfactory room temperature.
Annual heat demand fell from around 40.000 kWh to below 15.000 kWh.
Lambda value λ
The exceptionally low lambda value applies to the coating material itself. It describes the thermal conductivity of the layer, not the U-value of the finished component — that is determined by the entire wall build-up.
Basis System data PSC 250 T
U-value W/(m²·K)
In the system build-up examined, the coating achieves a U-value of 0.1. We guarantee this U-value for the selected package level.

Surface °C
After application, the interior-facing surface stays just below room temperature and thus well above the dew point and mould criterion. This is precisely the figure behind the component cross-section on the "How it works" page.

µ-value
A µ-value of 220 allows water vapour to escape, so the component build-up can dry out. Interstitial condensation must be assessed independently in accordance with DIN 4108-3.

Businesses that have worked with the coating — in their own words.
Thanks to the coating, we were able to raise the interior temperature of an office from 6–12°C to 19–21°C with the same heating output. This meant the poorly insulated room could be used again.
The straightforward application and the impressive results convinced us. Our customers are delighted.
