Interpon helps architects to deliver a cool answer to unwanted heat

AkzoNobel Powder Coatings has launched Interpon D2525 Low Solar Absorption, a powder coating that enables architects to imagine and deliver projects that create better and more sustainable environments by tackling the unwanted build-up of heat from the sun’s rays.

Whereas most traditional coatings absorb heat, Interpon’s D2525 Low Solar Absorption technology addresses the challenge of global warming and increased urbanization, as well as the need to reduce the carbon footprint of buildings in warm cities. 

Interpon D2525 Low Solar Absorption contains a special pigment that helps reflect a large part of the Near Infrared Radiation (NIR), which makes up over 50% of the total irradiated solar energy, from any aluminum substrate that it coats. Measured against Total Solar Reflectance (TSR - the measurement for the reflective performance of a coated surface), the Interpon D2525 Low Solar Absorption achieves an exceptional value of up to 65%. 

This has a dual effect: it reduces the thermal stress on the coated surface, thereby increasing the lifetime of the coated parts and contributing to the sustainability of the project; and it prevents the unwanted build-up of heat being deflected from the coated surface into a building that creates so-called ‘urban heat islands’ that are particularly noticeable in more densely packed built environments. 

Recommended for any new construction or renovated building envelope, Interpon D2525 Low Solar Absorption helps architects to design more comfortable spaces in which to live and work, and better enjoy the warm summer weather. It also means air conditioning units don’t have to work as hard to keep buildings cool and therefore consume less energy, adding a further benefit to its sustainability credentials.

It also has all of the ‘traditional’ benefits of being a powder coating in that it is free of Volatile Organic Compounds (VOCs), and as part of the superdurable Interpon D2000 family it is available in a range of different colors and finishes which can be customized on request. 

Bob Dirks, Global Segment Manager Architectural, AkzoNobel Powder Coatings, says the Interpon D2525 Low Solar Absorption is a win-win for architects championing creative thinking: “Challenging environments need robust innovation that can handle the heat over the long term and, crucially, deliver on sustainability. With our LSA range we’re proud to be giving architects a new way of creating better environments that allow people to enjoy the sun and its benefits and deliver spaces in which they can thrive for generations to come. When the heat is on, architects know they can trust Interpon to deliver!”

Interpon D2525 Low Solar Absorption is supported by an Environmental Product Declaration (EPD) – an independent verification of a product's environmental impact across its whole lifespan, from initial production to end-of-life disposal or recycling. And it contributes benefits to some of the leading green building schemes, such as LEED (Materials and Resources) and BREEAM (Materials) certified building projects.
