A very advanced system that is the perfect choice for new construction projects or refurbishing. The improved lintel trim comes complete with an indoor access hatch to keep the entire roller shutter properly sealed. The PU-foam filled sections improve the seal and prevent cold bridges across the curtain. The white sections harmonise with the window frame for an improved aesthetic finish. The innovative curtain structure and material facilitate installation for an ideal fit of the system components, an attractive effect, and high insulation performance.
