 There just outdoor air inside a roller shutter box - because the gap towards the outside, where the roller shutter exits the box, is permanently open towards the outside. Usually, just a board separates an old roller shutter box from the inside. Heat transmission is particularly high here (2.5 to 4.5 W/(m²K). Making improvements here is relatively easy and also helps a lot.

 |<WRAP box 10cm> It is quite easy to cut these panels to size using a sharp knife. A non-compressive low-isocyanate PU adhesive as well as double-sided tape proved suitable for joining these together. </WRAP>|{{:picopen:insulating_roller_shutter_boxes_03.jpg?nolink&400x257|insulating_roller_shutter_boxes_03.jpg}}|

-|<WRAP box 10cm> The cladding panel is now insulated and tape is also applied for protection. The cut-out for the belt can also be seen – a certain amount of leakage will naturally still occur near the opening for the belt, but this is just a single point; and if this is all that remains then the house will already be good :?: wenn das alles ist, was noch verbleibt, dann ist das Haus bereits sehr gut :?: . Of course there are also (relatively) airtight solutions for this as well. </WRAP>|{{:picopen:insulating_roller_shutter_boxes_05.jpg?nolink&400x404|insulating_roller_shutter_boxes_05.jpg}}|

-|<WRAP box 10cm> What is far more important is the connection joint of the panel, because its length is more than a metre. A matching sealing strip ("tubular seal") was applied here. The seals used here have proved successful in many applications. They are available in many different materials; for long durability we prefer those made of rubber or silicone ((Some other materials easily become brittle under the influence of UV light)) . The whole thing is then closed again, more than half of the heat losses in this area will be eliminated in this way. </WRAP>|{{:picopen:insulating_roller_shutter_boxes_06.jpg?nolink&400x585|insulating_roller_shutter_boxes_06.jpg}}|

 |<WRAP box 10cm> Because this has a complicated multi-dimensional structure, we calculated this using a numerical heat flow software program, "before" (left) and "afterwards" (right). This doesn't just provide a colourful picture but also shows the surface temperature distribution, which is now significantly better, as well as the total remaining heat loss, which is considerably reduced. </WRAP>|{{:picopen:insulating_roller_shutter_boxes_07.png?nolink&400x298}}|
