3 Sun-Activ - reflective SBS membrane Icopal and the environment Icopal is committed to the development of products and systems that address modern sustainable construction needs. Our highly innovative Eco-Activ range provides architects and specifiers with versatile and sustainable solutions such as cool roof solutions, depolluting membranes, photovoltaic mounting systems, green roof solutions, solvent free liquids and others. Make your roof cool with Sun-Activ The Sun-Activ membrane is a bituminous cap sheet for waterproofing with a highly reflective and smooth white surface. It is designed to comply with the Cool Roof concept that gains more importance as the demand for energy efficiency and environmental awarness increases. Smooth and reflective surface with high SRI Cool Roof concept: saving energy and cost High resistance and durability of the waterproofing Added value to your building The Sun-Activ membrane is especially beneficial for use on new or refurbished roofs: - with solar panel installations, - with a low amount of thermal insulation, - with a high amount of internal heat generation, - with air-cooling systems. Those are mostly offices and public institutions such as schools and hospitals, residential buildings and industrial premises. Icopal is a member of European Cool Roof Council (ECRC).

4 Cool Roof concept A cool roof efficiently reflects sunlight and keeps its surface cool by re-radiating the sun s heat back to its surroundings. The roof temperature stays lower therefore the amount of heat conducted into the building below decreases. Sun-Activ membrane makes it happen: its white, smooth and highly reflective surface makes your roof cool! How does it work? The cool roof performance is defined by a Solar Reflectance Index (SRI), which is a combination of Solar Reflectance and Thermal Emittance values. Solar Reflectance is the ability of a material to reflect sunlight from its surface back into the atmosphere. Thermal Emittance is the ability to re-radiate already absorbed heat. Beside other material caracteristics influencing the choice of a roofing product, the SRI velue is crucial to the cool roof concept. SOLAR REFLECTANCE: The ratio of reflected solar radiation from the roof surface. THERMAL EMITTANCE: The ability of the roof surface to release absorbed heat.

5 Sun-Activ - reflective SBS membrane Benefits Reduce energy consumption In the case of a low or poorly insulated roof during the summer period, a cool roof keeps the interior cooler, improving internal comfort. If a building has air conditioning equipment, the energy required for cooling is reduced. And if we reduce the energy consumption, we save money. It is as simple as that! If you want to know more about how Sun-Activ can reduce your energy bill, please contact us. Add value to your building Many of the existing building certification programmes specify the Cool Roof as one of the added value aspects in terms of optimisation of energy performance and reduction of the heat island effect. For exemple, to meet LEED requirements for a cool roof, a roofing material must have an SRI of 29 or higher for steeply pitched (>2:12) roofs and an SRI value of 78 or higher for flat or low pitched roofs. Therefore, with the Sun-Activ cap sheet (SRI value of 98), the building can gain points and increase its market value. Increase the service life of the waterproofing A cool roof coating protects the waterproofing from the destructive UV rays that can degrade the membrane over time. Thanks to the white, reflective coating of Sun-Activ membrane, the SBS compound is protected and the roofing maintanance cost decreses as the longevity of the waterproofing increases. Help the environment by reducing the urban heat island effect Many cities encounter the urban heat island effect resulting in smog formation and poorer air quality. This occurs where the combination of heat-absorbing building materials such as black roof coverings, dark asphalt parking lots and pavements, together with sparse green areas, increases air temperature by 1 to 3 C higher than the temperature in the surrounding areas. The Sun-Activ cool roof mitigates the urban heat island effect and consequently helps to improve the comfort of city residents.

6 Sun-Activ membrane Best choice for excellent performance of your cool roof The Sun-Activ membrane is an SBS bituminous waterproofing cap sheet with a polyester-glass fibre composite reinforcement. It is designed for multi-layer waterproofing systems which give the highest security level in terms of watertightness. Top surface: white acrylic paint resistant to UV radiation, smooth and highly reflective. Bottom surface: polypropylene thermofusible film. The SRI value of 98 is what makes the Sun-Activ membrane perfect for cool roof applications. The Sun-Activ cap sheet reflects 75% of the UV rays and releases 85% of the absorbed heat back to the atmosphere.

7 Sun-Activ - reflective SBS membrane Easy and traditional installation The Sun-Activ membrane is applied as part of a multi-layer system, installed on a base layer compatible with the substrate. The base layer can be a self-adhesive, mechanically fixed or torch applied bituminous or synthetic, new or existing membrane. This first layer is installed parallel to the direction of the slope according to its own installation instructions. Sun-Activ membrane is also installed parallel to the direction of the slope. Head laps of the Sun-Activ membrane should be staggered by at least 10 cm from the base layer head laps. Sun-Activ is fully torched in a traditional way onto the base layer with side laps of 8 cm and head laps of 10 cm. For more details about design, installation and maintenance please refer to the application instructions of the Sun-Activ membrane. If necessary, roofers can be trained by Icopal specifically for the installation of the Sun-Activ membrane! For multilayer systems Traditional installation High mechanical and UV resistance
