Four field measurements on three existing buildings, documented studies and testimonials from the field. Each figure states the conditions under which it was obtained.
The interior surface temperature was measured before and after application. Two of the four series come from the same building, measured under different conditions. The figures document the result for these three properties, not a universal temperature increase.
Measurement method: surface temperature measurement on the inside of the external wall, always at the same measuring point before and after coating, during the heating season. The boundary conditions for each property are given in the table and on the images below.
| Property | Boundary condition | before in °C | after in °C | Difference in K | Basis |
|---|---|---|---|---|---|
| Residential building, built 1890 | outside 2–5 °C, inside 20 °C | 12,0 | 19,0 | +7,0 | Field measurement |
| Residential building, built 1900 | Solid brick 400 mm, outside 0 °C | 12,9 | 19,0 | +6,1 | Field measurement |
| Residential building, built 1900 | Flow temperature constant 36 °C | 12,3 | 18,6 | +6,3 | Field measurement |
| Residential building, built 1960 | Concrete, ceiling heating, outside 4 °C | 11,0 | 19,0 | +8,0 | Field measurement |
| Reference line: 12,6 °C minimum surface temperature. It follows from the requirement fRsi >= 0,70 per DIN 4108-2 under the boundary conditions standardised therein (20 °C indoor air, -5 °C outdoor air). The boundary conditions of the three properties differ from this; the line serves as a point of reference. The four value pairs are measured on site. | |||||
Three properties where the build-up was examined and the U-value determined before and after. The figures apply to the specific build-up examined and are not a guarantee for any given existing component.
Study 01
A multi-family building was coated with a 1 mm layer of PowerSmartCoat.
U-value reduced by around 96%
Study 02
Investigation of the effect on petrol storage tanks in ongoing operation.
Reduced evaporation losses
Study 03
Comparison with conventional insulation materials on a listed heritage façade.
Faster payback
One image of the property per measurement series. A thermal camera rescales its colours for each image — so the displayed measurement points are comparable, not the colours.
Two images of the same façade before and after coating, under comparable winter conditions. The building previously required high heating output and still did not get warm. Annual heat demand fell from around 40,000 kWh to under 15,000 kWh.
The image compares room air — measured at the curtain, 20.0 °C — with the external wall next to it: 19.0 °C. Below it is the component calculation for exactly this wall. It predicts 12.9 °C on the inside and rates the wall as deficient. The measured value was 19.0 °C.
Both images at the same flow temperature. On the right, the starting situation with 10.4 °C at the concrete lintel above the window and 12.3 °C at the wall; on the left, the same spot afterwards with 18.6 °C to 20.4 °C. The thermal bridge at the lintel recedes even though the heating runs unchanged.
The load-bearing concrete structure remains visible in the thermal image. Despite the high thermal conductivity of concrete, 19.0 °C is measured at these critical points; the thermally more favourable brick infill panels now differ only slightly from the internal wall on the left of the image.
The coating has been used in industrial plant engineering for years — on pipelines, tanks, and halls. The following companies use it in their facilities.
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.
