PRB Cool+ Roof, think to save

This solution is therefore part of an approach to combating urban heat islands and improving the energy efficiency of buildings.

A rapidly changing market: growing climate and regulatory challenges

Global warming and rampant urbanization are leading to a significant rise in urban temperatures, promoting the formation of heat islands. According to the IPCC, cool roofing, which involves applying reflective coatings to roofs, is one solution for significantly reducing greenhouse gas emissions, combating heat islands, and lowering the indoor temperature of buildings.

Furthermore, new regulations such as RE2020, with the hourly degree, and the tertiary decree impose increased obligations in terms of reducing energy consumption.

In this context, the adoption of innovative solutions such as PRB COOL+ ROOF becomes a strategic lever for building professionals and infrastructure managers.

PRB COOL+ ROOF: an effective and responsible solution

PRB COOL+ ROOF is a thermo-reflective system composed of a PRB COOL+ ROOF BASE and a finish PRB COOL+ ROOF TOP.

Designed to improve the thermal performance of buildings, it offers several advantages:

• High thermo-reflective performance: solar radiation is strongly reflected and heat absorption is reduced, helping to lower the indoor temperature by up to 6°C.
• Reduced air conditioning requirements: Energy savings of up to 45% can be achieved, reducing operating costs. This reduction in air conditioning requirements contributes to a reduction in CO02 emissions.
• Improved solar panel performance: the increased reflectivity of the roof allows for an energy production gain of 6% to 25%, and up to 40% for bifacial panels.
• Durability: reducing the temperature rise of the roof, and de facto of the building as a whole, limits the phenomenon of heating of the supports, ensuring greater longevity of the waterproofing complex
• Contribution to the fight against urban heat islands: by reducing the temperature of roofs, this technology actively contributes to cooling cities

Optimal performance thanks to high-quality products

The PRB COOL+ ROOF system is based on two complementary products:

• PRB COOL+ ROOF BASE : the thermo-reflective base coat guaranteeing excellent adhesion on many surfaces, preventing bitumen from rising and ensuring a uniform application.
• PRB COOL+ ROOF TOP : the highly reflective organic finish, which optimizes the durability of the thermo-reflective properties. Its specific PVDF-based resin protects the finish from dirt and wear and allows the finish to remain white for up to 20 years.

The PRB COOL+ ROOF system has a high Solar Reflectance Index (SRI) of 118, ensuring optimal long-term thermal performance.

A solution adapted to a wide range of destinations

PRB COOL+ ROOF is designed to adapt to various types of buildings: logistics warehouses, industrial buildings, hypermarkets, logistics platforms, agricultural buildings and ERP.

It can be applied to a wide variety of substrates: bituminous derivatives, fiber cement sheet, steel tray, shingle, cement/concrete tile, non-ferrous/galvanized metals.

Conclusion

With PRB COOL+ ROOF, PRB confirms its commitment to innovative and sustainable solutions for buildings.

By providing an effective response to the challenges of thermal comfort, energy efficiency and the fight against urban heat islands, this technology is establishing itself as a strategic choice for professionals in the sector.
