The flush mounted

SP & SP-E flush mounted roller shutters

Flush-mounted systems are mainly designed for new buildings. However, once the necessary modifications to the lintel are made, these products can also be installed in existing buildings. It is important to plan the use of such solutions, this also applies to the installation method, as early as at the building design stage to allow for the effective use of the product’s functional values. Flush-mounted systems bring excellent thermal insulation performance as they do not require any modifications to the existing windows, doors or lintels, and thus do not affect the building’s energy use. What’s more, they perfectly fit the building’s façade and form an integral part thereof.

The front section of the roller-box is equally a basis for any finishing material (plaster, clinker, etc.) so that it remains an unnoticed element of the façade. Aluprof’s SP and SP-E systems are designed to ensure, first and foremost, a good protection against heat loss. This was especially appreciated by the Passive House Institute in Darmstadt (PHI), and the organization has issued a recommendation to apply both these solutions for 165 mm boxes (and smaller) in passive buildings. But it’s the proper installation in a previously insulated lintel in accordance with manufacturer's guidelines that is an essential condition here. In addition, window joinery should comply with the appropriate parameters, i.e. heat transfer coefficient of the window Uw is lower than 0.80/(m²K) while the glass pane coefficient Ug does not exceed 0.70 W/(m²K).

An additional advantage of the flush-mounted roller shutters is the ability to apply an independently-working insect screen to protect the interior from insects. As it is the case for front-mounted systems, the roller’s curtain can be made of foam-filled, plastic or extruded profiles.
