DERBIBRITE NT® - Предварительно изготовленная битумная мембрана

High reflectivity DERBIBRITE NT® boasts very high reflectivity (81 %) and emissivity (81%) values, thanks to its exclusive 'ceramicised' coating.‎ This means that DERBIBRITE NT® reflects most of the sun's rays it receives and re-emits most of the small amount of heat it absorbs.‎ In fact, theSRI (Solar Reflectance Index, calculated according to ASTM E 1980-01) is 100.‎ Surfaces with the highest SRI value are the best choice for exterior cladding.‎ The new decree of 26/06/2015 on calculating the energy performance of buildings makes it compulsory to verify the effectiveness, use of materials with high solar reflectance (0.‎65 in the case of flat roofs; 0.‎30 in the case of pitched roofs) or passive climate control technologies, such as ventilation or green roofs.‎ In contrast to roofs made of traditional waterproofing membranes, which normally reach 80-85° C in summer, a roof made of DERBIBRITE NT® never exceeds 40-45° C.‎ For this reason, even in unconditioned buildings, wellbeing is significantly increased (up to 5° C lower).‎ No heat island The concentration of dark-roofed buildings in urban centres means that the temperature in cities is several degrees higher than in the countryside and suburbs.‎ This phenomenon is known as the 'heat island'.‎ This increases the energy demand for air conditioning, which also has a negative influence on CO2 emissions.‎ Economic savings A cool roof cuts air conditioning costs Less heat on the roof means less heat inside buildings.‎ This translates into a significant decrease in indoor air conditioning costs.‎ Studies and computer simulations have shown savings of up to €4 per square metre of roof per year (depending on the characteristics and use of the building).‎ A DERBIBRITE NT® roof increases the yield of your PV system A white roof keeps the operating temperature of crystalline photovoltaic panels low (whose yield decreases by 0.‎5% for every degree above 25° C), limiting yield degradation.‎ In addition, the diffused and reflected light from the white surface expands the light source to the benefit of the photovoltaic panels.‎ Optimise your investment and speed up your return on investment.‎ Cut CO2 Thelife cycle analysis of DERBIBRITE NT® is eloquent All aspects of production and product life were included in the calculation: from the production and transport of all raw materials to the manufacturing process and roof application, as well as the life cycle benefits in terms of energy requirements and pollutant emissions.‎ The result? A roof made with DERBIBRITE NT® avoids 19 times the CO2 emissions required to produce it.‎ An exceptionally positive balance.‎ Saving the earth'sresources DERBIBRITENT® optimises resources Before the end of September, all the resources the earth has available for that year are consumed.‎ In the remaining months, the resources of the future are eroded.‎ The advantage of DERBIBRITE NT® does not end at the end of its life on the roof.‎ DERBIBRITE NT® is fully recyclable, and when it is disposed of, its constituent materials return to the production cycle.‎ DERBIGUM uses only energy from renewable sources, does not waste and has lowered its environmental impact.‎ Numerous awards and certifications testify to the results of its efforts (European EMAS Award 2008, ISO 14001).‎ Recycling rainwater The neutral pH of the surface A truly intelligent building wastes no resources.‎ The special coating of DERBIBRITE NT® is pH neutral.‎ This exceptional characteristic means that rainwater that reaches the roof is not contaminated, allowing it to be reused for domestic, industrial or non-drinking sanitary purposes.‎
