Energy-saving guarantee

You don't have to take our word for it. We measured.

Our energy-saving guarantee is based on verifiable measurements on real buildings – with measurement conditions, building data and documented readings.

Residential building · built 1890

Outside temperature
+2 / +5 °C
Room temperature
20 °C
Wall surface before
12 °C
Wall surface after
19 °C

Thermography before and after coating under comparable winter conditions. Annual heat demand fell from around 40,000 kWh to under 15,000 kWh.

Residential building · built 1900

Outside temperature
0 °C
Room temperature
20 °C
Wall surface before
12,9 °C
Wall surface after
19 °C

Comparison of room-air and exterior-wall temperature: after coating, the wall surface reaches almost room temperature.

Residential building · built 1900

Outside temperature
5 → 3 °C
Room temperature
16 → 20,5 °C
Wall surface before
12,3 °C
Wall surface after
18,6 °C
Flow temperature
36 °C

At a constant flow temperature, room temperature rises significantly; massive thermal bridges such as the concrete lintel above the window recede.

Residential building · built 1960

Outside temperature
4 °C
Room temperature
20 °C
Wall surface before
11 °C
Wall surface after
19 °C

Ceiling heating. Despite the high thermal conductivity of the load-bearing concrete structure, surface temperatures of 19 °C are measured at the critical points.

Apartment building · built 1900

Outside temperature
3 °C
Room temperature
≈ 22 °C
Wall surface before
19,7 °C (EPS)
Wall surface after
21 °C (PScoat)

Listed façade with PScoat Build + Outside, the rest of the building with 12 cm EPS (λ 031), gas heating. The PScoat-coated walls are consistently warmer than the conventionally insulated ones.

The corresponding thermography images (before/after) will be added.

How does the guarantee work?

We guarantee that the U-value of the treated exterior wall corresponding to the chosen package is achieved. On request, we back this up with a documented U-value measurement before and/or after coating (optional add-on).

What is guaranteed is the effect at the wall, which correlates with corresponding savings – not the individual heating behaviour of the occupants or leaks in the building envelope.
