White roofing: cool, durable, and profitable
Benefits of white roofing
- lower energy costs thanks to less need for cooling.
- longer lifespan due to less thermal load on the roof.
- more pleasant indoor climate during hot spells.
- less heat stress in urban environments.
- higher yield of solar panels due to a cooler roof surface.
- sustainable choice with lower CO₂ emissions.
Advice on white roofing?
Looking for a solution for a cooler and more energy-efficient roof?
Supergum+ White: the smart choice for a cooler and more energy-efficient roof
Supergum+ White Deschacht is a high-quality bituminous roof membrane with a reflective white slate finish. Thanks to its high reflectance value, the roof absorbs significantly less heat, resulting in better energy performance and a longer lifespan for the roofing.
The Benefits of Supergum+ White
- higher solar panel efficiency thanks to the reflection of extra sunlight.
- lower roof temperature, which reduces thermal stress and aging of the roof.
- lower energy consumption due to a reduced cooling demand in the building.
With Supergum+ White, you are choosing a sustainable roofing solution that combines comfort, energy savings, and performance. Ideal for new construction and renovation projects where energy efficiency is key.
White roofing and solar panels: the perfect combination
White roofing and solar panels together form an efficient and sustainable solution. The reflective roofing keeps the roof cooler, allowing solar panels to perform better and achieve a higher yield. In addition, the thermal load is reduced, which benefits the lifespan of both the roof and the solar panels. This way you enjoy a higher energy yield, lower energy costs, and a more sustainable investment.
FAQ
1. For which types of buildings is white roofing most suitable?
White roofing offers the most benefits on large flat roofs of logistics centers, commercial buildings, offices, schools, healthcare institutions, and industrial buildings where overheating is a major concern.
2. What contribution does white roofing make to the lifespan of the roof?
Due to the lower roof temperature, the thermal load on the roof structure is limited. This reduces stresses in the roofing, which can contribute to a longer lifespan and lower maintenance costs.
3. What role does albedo (reflectance value) play in white roofing?
The albedo value determines how much solar radiation is reflected. White roofing has a high albedo, which means less heat is absorbed and the surface temperature of the roof remains significantly lower than with dark roofing materials.
4. How does white roofing affect the thermal load of the roof structure?
Lower roof temperatures limit the expansion and contraction of materials. This reduces thermal stresses throughout the entire roof structure, including insulation, vapor barriers, and waterproofing.
