Roofs were once meant to block out the light. With SEP, this is no longer the case. Roofs realised with Sep polycarbonate panels allow the passage of up to 78% of the light coming from the outside. As a result, workplaces look more pleasant, as well as being safer, lively and positive. Not less importantly, much energy can be saved. Whether a flat roof, a curved roof or a walkable skylight is needed, SEP panels can match you requirements, ensuring perfect watertightness, thermal insulation, soundproof effect and service temperatures ranging from -40 to +120°C. And above all: SEP quality, of course.
