Neotex - Neoroof
Hybrid waterproofing coating for roofs with UV cross linking system. It is certified product, with high reflectance and total emittance providing thermal insulation. It forms a non-penetrating against moisture film with resistance to extreme low temperatures up to -35oC. Basic application is also the coating of the mineral bitumen membrane with gravity stone.
Fields of Application
- Roofs made of concrete, cement boards, mosaic, cement slurries
- Rooftops with resistance to stagnant water
- Mineral bitumen membranes
- Metallic surfaces
- Beside and under photovoltaic panels, enhancing their efficiency
- Air-conditioning tubes
- New or old polyurethane waterproofing layers
- Thermal-insulating polyurethane panels and polycarbonate panels
- Glass surfaces
- Galvanized metal sheets and bituminous membranes with aluminium sheet surface
- Over old roofing made of asbestos
(Upon some surfaces above, it is necessary to prime them with the appropriate each time primer, before Neoroof® application)
Properties and advantages
- It is easily applied and dries into a smooth film that covers capillary cracks and provides total protection against moisture.
- Neoroof® has a UV cross-linking system incorporated, designed to give very good dirt pick-up resistance. After 2 days exposure to direct sunlight the film is no tacky even under high temperatures.
- It is not affected by adverse weather conditions and maintains its elasticity for temperatures from -35oC to +80oC, offering excellent impermeability to water.
- It reflects the solar radiation and significantly reduces the energy consumption during summer period
- Due to high reflectance and total emmitance, it decreases the temperature of the external surface that is exposed directly to the sun, up to 40%.
- It offers cool atmosphere during summer and energy consumption reduction for air-conditioning.
- Eco-friendly contributing to the elimination of the ‘urban heat island’ phenomenon and to the atmosphere pollution restriction, due to CO2 emissions decrease.
- It delays the aging of the mineral bitumenous membrane
