A US patented reflective coating from Denmark is being introduced to the UK market as a means to protect against heating in urban areas and limit energy needs for cooling functions
Danish manufacturer Nowocoat has obtained a US patent for a solvent-free coating that builds on research into stealth jet technology in order to limit heat absorption from the sun and lower the overall temperatures in buildings.
The company said it has been able to patent the structure and process for developing its Coolingpaint product, which is described as an infrared reflective surface coating that is now being brought to the UK market.
Nowocoat claimed that the product originates from work by the US military to develop aircraft that was less visible to radar. Ongoing development has led to new approaches to chemical composition of the paint and pigments it contains.
Microscopic mirrors have been added to the pigments that are able to reflect 90 per cent of the sun’s infrared rays, reducing the estimated amount of heat absorbed by 20 per cent, according to the manufacturer.
The paint is also designed with anti-fungal and algae-inhibiting properties to ensure protection for building facades, rooftops and woodwork
Nowocoat chief executive Ole E. Jensen said that the product was expected to have significant potential in trying to tackle issues of overheating, particularly in urban areas where buildings and people absorb and then give off heat.
“An untreated roof can reach surface temperatures of 90 deg C, while the temperature on a roof treated with Coolingpaint Roof is reduced by up to 15 per cent. In practice, this means that it is possible to reduce the Urban Heat Island effect and, not least, reduce the energy consumed by cooling units placed on the rooftop. The better that surfaces are able to reflect the sun’s rays, the more the temperature can be kept down - both on the surface and inside the building.”
The manufacturer is in the process of trying to supply private label or own-brand solutions based on the Coolingpaint for existing covering and paint manufacturers in the UK. The product is intended to be pushed as reducing energy needs of building for cooling.
Mr Jensen said that Coolingpaint also carries the EU ecolabel mark, reflecting its compliance with environmental standards.
He added, “This also means that Coolingpaint does not contain heavy metals, softening agents and harmful amounts of solvents. At the same time, it has been quality tested in accordance with international standards for coverage and opacity, UV-stability, adhesion, peeling, blistering, crack formation, high weather resistance, fungal and algal growth, gloss and colour change and the ability to reflect infrared rays.”
