In response to demand from the market, Derbigum is expanding its range of white roofing. White roofing reflects sunlight, resulting in passive cooling inside the building: In the summer, the temperature can be reduced by 5 °C or more. In addition to the bituminous roofing with the white acrylic coating Derbibrite® NT, and the plant-based variant Derbipure®, there is now also a bituminous version with reflective crushed white slate: DERBICOLOR® FR White. The Derbicolor FR White was launched at the international roofing trade fair Dak Event, held from 21 to 23 January in Nieuwegein, the Netherlands.
What are the advantages?
• High-quality APP-TPO bituminous membrane
• Proven usable lifetime of more than 30 years
• Colour-fast white slate with optimum adhesion • Good sunlight reflection
• Ecologically responsible
Because the white slate reflects sunlight, the temperature of the roof is significantly reduced. This means substantial savings on the costs of cooling the building.
As from 1 January 2013, it is possible to apply for a subsidy for roof insulation in combination with white roofing through the Netherlands' 2013 Energy Investment Allowance (EIA). The EIA is a scheme permitting a deduction of 41.5% from the costs of investments in energy-saving corporate assets. This deduction is in addition to the regular investment tax credit. In addition, in some cases it is possible to take advantage of the MIA and/or VAMIL tax schemes for environmental investments in businesses.
