SP-E concealed roller shutter

Pre-wall systems  are designed for use primarily in newly erected buildings, but also in existing buildings after making the necessary changes to the lintel. It is important to plan the use of such solutions and the method of their installation even at the stage of building design, which allows more efficient use of their functional advantages. SP and SP-E systems provide excellent thermal insulation, as they do not interfere with the structure of the window, door and lintel, thus not affecting the energy balance. What’s more, these products fit perfectly into the facade of the building, forming an integral part of it. At the same time, the front of the roller shutter box is an underlay for any finishing material (such as plaster), thanks to which the box becomes an unnoticeable element of the building facade.

The structural elements, i.e. the inspection cover and guides, can be color-matched to the window joinery. As in the case of adaptive systems, the shutter curtain can be foam-filled, plastic and extruded profiles. Roller shutters in flush-mounted systems can be equipped with anti-insect netting, which provides effective protection against insects while maintaining the flow of light and fresh air to the interior

The Darmstadt Passive House Institute (PHI) has recognized the properties of roller shutters in SP-E systems. The organization has issued a certificate for boxes of size 165 or smaller, which, in both systems, can be successfully used in buildings with low energy requirements if the installation requirements according to the certificate are met. SP-E roller shutters are flush-mounted systems, in which the box is built in and its face is at the same time an underlay for the finishing material. Such a design means that the roller shutter elements do not interfere with the structure of the window or the lintel, so the tightness of the building remains intact. SP and SP-E systems have been developed to provide protection against heat escape and, at the same time, an aesthetic finish to the facade. Importantly, proper installation allows the use of any window that meets the requirements of the Institute of Passive Houses, whose heat transfer coefficient of the window Uw is lower than 0.80 W/(m²K) while the Ug coefficient of the glass does not exceed 0, 70 W/(m²K).
