Benefits of exterior window roller blinds in the summer period
Windows let in up to 80% of the sunlight leading to excessive insolation of rooms during summer. By using external roller blinds, it is easy to reduce this undesirable effect. Unlike internal roller blinds, external ones reflect solar beams already before they reach the window glass, preventing rooms from being heated. In summer you can feel the benefits of external roller blinds in the form of shading and pleasant coolness in rooms.
Benefits of exterior roller blinds in the winter period
Windows are one of the major sources of heat loss in the building structure (15-25%). By using external roller blinds this undesirable effect may be easily reduced. Between the window and a roller blind curtain there occurs a so-called air pad which serves as an additional insulation layer. In winter external roller blinds reduce the demand for energy in the building, significantly decreasing the cost of heating ‒ even up to 30%.
