Pharmacy in Witten

Economical and energy-efficient renovation. The use of ClimateCoating® for the modernisation freed up the money for a new granny annexe.

The renovated building of the Central Apotheke in Witten has become a jewel. The facade coating with the thermoceramic membrane technology ClimateCoating® ThermoProtect applied by the painting company Fox & Fox protects against summer heat and heat loss in winter. ClimateCoating® ThermoProtect was also used for the medicinal herbs painted by Dortmund artist Denis Klatt. The paint is very durable and also dirt repellent.

Michael Hillebrecht, creative head of the Wellmess project group, Witten, bases his concepts strictly on the criteria of economy and energy efficiency. For this reason, he decided to use a combination of energy-saving paint, a combined heat and power unit and photovoltaics to generate electricity on the roof for this project. During the partial conversion, a residential unit was created in the basement.

The pictures show the facade in the first year after completion. The energy certificate issued by Berlin-based DIMaGB Energieberatung for the energy-efficiently renovated building makes it clear what energy efficiency means, even in a modernised old building: “everything is in the green”.

Cost-effectiveness in this project means: high benefit at justifiable expense and a manageable payback period. The money saved on investments in the facade through the use of ClimateCoating® was used to create an apartment. Income accrues to the owner from rental and electricity remuneration.

Facade test after 9 years: A facade coated with ClimateCoating® is easy to clean

The manufacturer, SICC GmbH in Berlin, claims of its product ClimateCoating® ThermoProtect for facades: “Facades and walls stay like new – even after many years! ClimateCoating® reduces the electrostatic charge of the coated surfaces and prevents chemical bonding with dirt particles. If dirt does accumulate after a few years, the combination of ceramics and extremely resistant substrate material makes it possible to clean all coated surfaces with water and even with high-pressure equipment without any problems. ClimateCoating® Exterior thus ensures above-average color durability and consistent color brilliance.”

The practical test
During a practical test on 03.03.2015 in The Hague, it was repeatedly proven that these statements are true. The age of the facade coating was 9 years (Q.1 2006). For the test purpose, two spots on a gable were cleaned: the left one with water only, the right one with the addition of soap.

The result speaks for itself
“If some dirt does build up after a few years, the combination of ceramics and extremely resistant substrate material makes it possible to clean all coated surfaces with water without any problems.”

The Black House in Holland 01

The Black House in Holland

The original type (2013: 15 years) was followed by others.

Years before there was any talk in professional circles about light coating and TSR values, a house was painted black with ClimateCoating®. “The Black House” in Holland was based on an idea by Jan de Lange. This is, so to speak, the archetype of the Black ClimateCoating® house. After 15 years in the real field test of outdoor weathering, Mr. van Leeuwen in 2013 a picture of the current state:

Although the paint has discolored after 15 years, it is still without cracks and bubbles. A single layer is now sufficient to restore the original image.

1998: This is the first object treated with ClimateCoating® in the Netherlands. The house and barns were protected by ClimateCoating® ThermoProtect. 2013: Today the paint is discolored and needs a refresh. This is done with ClimateCoating® Nature, which did not exist at that time.

This forefather of the Black ClimateCoating® House was followed over the years by others, not only in Holland and not only made of wood. In 1998 ClimateCoating® was still imported from the USA, since 2003 production has been “made in Germany” at the Berlin site. After many years of research and development, SICC has developed Nature, the special ClimateCoating® for wooden building components, from the tried and tested façade coating.

The heat flow measurement for Rome 01

The heat flow measurement to Rome

Winter 2015/2016

As is well known, it is deliberate mischief to re-measure a specimen coated with ClimateCoating® in the hotplate device, as there is no surface left with this method – no surface, no surface activity. Furthermore, in hotbox and climatic chamber experiments in the laboratory, experience has shown that miniaturization of the experimental set-up does not yield results.

Therefore, Italy has gone the way of carrying out a practical test with a very large hotbox. For this purpose, measurements were carried out in the period 11.12.2015 to 25.01.2016 at Via Merulana 121 in Rome. The building has walls made of tuff blocks with a thickness of 80 cm on the ground floor to 40 cm on the upper floors.

The “very large hotbox” was a room on the ground floor with a wall 80 cm thick. The heat flow meter 435-2 from Testo was used for the in situ measurement of the heat permeability before and after the application of the product ClimateCoating® ThermoProtect. Long before the measurement, a calculation of the improvement in the thermal insulation properties of the wall was carried out using the calculus tool Calculus with the ClimateCoating® fTS calculation values.

The test led to the following conclusions: The heat flow measurements carried out confirmed the calculation from July 2015 with a good approximation of the data. An improvement of the equivalent U-value by 33% was calculated. A change in thermal conductivity from 0.71 to 0.48 W/mK was measured. This corresponds to 32%.

ClimateCoating® for half-timbered houses 01

ClimateCoating® for half-timbered houses

The photo collection on the theme of “half-timbered houses” shows shots from 2012 to 2015. The ClimateCoating® coating of the half-timbered houses was carried out in the combinations Exterior + Nature or History + Nature, Fix Plus or Nature Primer was used as a primer.

ClimateCoating® Nature for wooden components was developed to meet the special requirements of the oldest and most natural building material. Precisely because wood is so alive, it reacts sensitively to weather influences such as moisture, UV radiation, air pollution as well as fungi, pests and insects. That is why wood needs care and protection.

For historical buildings the product ClimateCoating® History is used. Almost every mineral substrate in old buildings is contaminated with water and salt. History fulfils the requirement of monument protection for a coating that is optimally open to capillary and diffusion, which should prevent salt and moisture build-up and also withstand all modern environmental stresses.

The combined application of the mentioned products for plaster and wood is the logical conclusion from the observed long-term performance on different facades and in different regions. The preventive advantage for half-timbered houses coated with ClimateCoating® is primarily the thermal calming and weather protection, especially against driving rain.

ClimateCoating® Nature strongly reduces the swelling and shrinkage of the wood. In addition, there is the excellent flank adhesion of both products – i.e. on wood and on plaster – as well as the crack-bridging, elastic properties of the ClimateCoating® membrane. This explains the very good suitability of ClimateCoating® for half-timbered facades.

The white house in Spaarndam

ClimateCoating® Nature compared to other products

No, it is not a second residence of the American president, nor is the comparison to be made with the original in Washington. Rather, the reference is to the pioneer of wooden house coating, which was reported in 2006 from Spremberg near Cottbus.

The object is a detached house in 2064 KW Spaarndam (NL), Lagedijk. It is located in open terrain in close proximity to the water. The orientation of the façade to the south results in a longer exposure also to sunlight. The lack of neighbouring buildings contributes to the fact that the house is also exposed to the wind.

The Meranti façade was thoroughly renovated 4 years ago. Since the old coating was in very poor condition, it was completely removed at that time. After some minor repairs, a double coat of primer was applied and then painted with satin varnish from S.

After only 4 years, it became apparent that renovation was again necessary due to weathering. In addition to the renewal of the coating, it also became apparent that some repairs had to be carried out again. The old paint had bubbles at the tongue and groove joints of the panel joints and some panels were defective.

Consideration of the alternatives revealed that repeating the same treatment would have been a costly affair; high labour and material costs would have been offset by a fairly short service life. Replacing the wooden panels with plastic parts would have required an investment of about EUR 4.5 to 5 thousand. The application of ClimateCoating® provides many years of protection.

Ultimately, the owner opted for option 3: the application of a ClimateCoating® coating. After the repairs and sanding of the old coating, ClimateCoating® Nature was applied twice. Afterwards, ClimateCoating® GlossPlus, a colorless protective coating, was applied.

The following experiences were made: In addition to various compliments from residents about the visible results, it was felt in the house that some things had changed. As a rule, the temperature in the house at the end of a sunny day is very high, especially in the bedroom behind this facade. After applying ClimateCoating® Nature, the first sunny days showed that the temperature in the house was 5-6 degrees Celsius lower than before.

Interesting to know:
in Holland good experiences have also been made with coatings in black.
