Stay cool

Anyone who has ever had to sit on a black car seat in the height of summer knows the problem: dark colours absorb sunlight and convert it directly into heat. This effect presents significant challenges for professional painters, as surfaces expand when heated by the sun and contract when cooled. This can lead to unsightly cracking and significantly shortens the lifespan of dark coatings, in particular. However, even light-coloured surfaces suffer from long-term thermal buildup.

With the development of COOL COLOURS, RELIUS has solved the problem of thermal buildup and once again set new standards for professional painters. This innovative technology makes it possible to create significantly more durable surfaces while also greatly expanding the range of available colours. The COOL COLOURS by RELIUS products ensure that the heating effect is significantly reduced, thereby improving the chalk resistance, gloss retention, and colorfastness of surfaces. In the future, professional painters and their customers can stay cool, regardless of the weather or the colour they choose, with COOL COLOURS by RELIUS.

In external thermal insulation composite systems (ETICS), the installation of thermally insulating panels on the coating surfaces leads to increased thermal movement. Previously, efforts were focused on minimizing the risk of cracking and deformation of the insulation panels, particularly with polystyrene rigid foam boards, by generally limiting the surface temperature through the use of light colours or by implementing complex construction measures during the installation of new ETICS. When renovating existing ETICS, the options for colour selection were generally limited to shades with a light reflectance value (LRV) above 20.

Whether renovating existing exterior insulation composite systems (EICS) or installing new ones, a double coat of the RELIUS RELINOVA NANO TECH facade paint, featuring COOL COLOURS by RELIUS, is sufficient to eliminate the risk of excessive thermal movement, deformation, or cracking. Furthermore, there is no longer a need to consider light reflectance values. With this new technology, trendy facades in vibrant colours, even black, are now achievable.

The roof of a residential building or commercial property must withstand a great deal: heavy rain, icy cold, and scorching heat. It requires the best possible protection, which is what the RELIUS ROOF ACRYL NANO TECH roofing coating system provides. Equipped with the COOL COLOURS by RELIUS technology, the roof no longer becomes a heat trap, even with dark, vibrant colours. The living space beneath the roof, especially in older buildings with poor insulation, does not heat up as much in the summer, making living much more comfortable. Another positive side effect is the reduction of summer overheating in entire city districts, particularly in large cities.

The RELIUS ROOF ACRYL NANO TECH roof coating system is ideal for renovation, new coatings, or simply for long-term protection.

When it comes to dark shades in paints and stains, professional painters and paint retailers can better meet customer requests with COOL COLOURS by RELIUS. Because the versatile RELIUS HYDRO A-Z HAUSLACK, based on acrylic, as well as the water-based stain range are also equipped with this innovative technology.

For wooden houses, garden furniture, doors, windows, and many other wooden components, the colour palette becomes more durable because they are much better protected from thermal stress due to their infrared-reflective coating. The durability and colorfastness of the coating are significantly extended with COOL COLOURS by RELIUS.

And for wooden frameworks, for which the proven acrylic paint RELIUS HYDRO A-Z HAUSLACK is particularly praised, completely new and fantastic colour possibilities arise.
