Easy Retrofitting for Uninsulated Roller Shutters!

Roller Shutter Box Insulation reduces heat loss by 70%!

Roller shutters boxes create thermal bridges and therefore a weak point in the external façade of the house! If they are not insulated properly the can raise the heating costs unnecessarily high! Therefore it is an important reason to think about optimal roller shutter box insulation.

Benefits of Roller Shutter Insulation:

  • Reduced heating prices: reduces heat loss by 70%
  • Increased living comfort: effective noise reduction
  • Improve your energy-saving: meets the requirements of the energy saving regulations (EnEV)
  • Less environmental impact through better emissions

Necessary Tools:

  • Pencil or pen and measuring tool
  • Utility knife
  • Mounting foam

Step 1

Make the roller shutter box accessible and open it carefully.

Tip: Once you have the roller shutter box open and ready, consider installing a Schellenberg tubular motor. In assortments you can find various control elements for your needs.

Step 2

Pull up the roller shutters completely and measure the distance from the shutters to the top of the box.

How to determine the appropriate insulation thickness: Prior to installation, you should familiarize yourself with your space in the roller shutter box. What roller shutter box insulation you choose not only depends on the financial aspect and good will but also on the available space. Pull the blinds completely up and measure the distance from the shutters to the top of the box and then decide the right shutter box insulation.

Step 3

In our example the roller shutter box requires insulation that is 25mm thick. The 13mm insulation would not be sufficient.

Tip: If your window exceeds a width of one meter (3.2 feet), you will need a specific sized insulation panel for effective insulation. Both insulations from Schellenberg have a width of one meter.

Step 4

Measure the width.

Step 5

Measure the height. Decide on the insulation thickness with the gathered dimensions (either 13 or 25 mm).

Tip: The necessary dimensions are measured from inside

Step 6 & 7

Measure the depth of the roller shutter box above and below the roller shutters (above for insulation mat and below for the bottom panel).

Step 8 & 9

Cut the bottom panel to the necessary width and height.

Important: When cutting be sure to do so on the grooved side. The structure of the insulation allows for a clean cut.

Before you cut the insulation mat, determine the depth. This is the result of the height measurement plus the width (above) minus 5 cm.

Step 10 & 11

But the insulation mat to the necessary width and height

Important: If your roller shutters are manually operated, cut an entry slit for the shutter belt in the insulation mat!

Step 12

Set the bottom panel inside the box. Make sure that the grooved side is facing up. Secure the panel with adhesive or mounting foam.

Step 13

The next step is to insert the insulating mat (over the upper half of the shutters) and then connect the tongue and groove system (bottom panel with the insulating mat). Put in the next step, the insulating mat (first upper half of the tank), and then connect tongue and groove (baseplate and insulating mat). If available, now the roller shutter can be positioned.

Step 14

With the adhesive foam used previously, you can now seal the sides of the shutter box insulation for additional sealing.

Tip: If you need more insulation for the width, you can cover the extra insulation with foam. This optimizes the insulating properties, provides additional protection against drafts and heat loss as well as prevents the formation of mold.
