ᐅ Insulation During Renovation Around the Roller Shutter Box – Preventing Mold?

Hello everyone,

a quick overview of the situation:

• We have a house where windows were ventilated with three quick air exchanges daily.
• There are radiators under the windows (removed for renovation).
• The windows are double-glazed.
• The windows have manual roller shutters that are not well insulated.
• There is also some mold on the second sealing layer at the window.
• The problem occurs in every room at every window.
• All walls are covered with wallpaper and there is laminate flooring.

The idea is to install electric roller shutters, properly insulate the shutter boxes, and possibly replace the window seals.

Will this solve the mold problem?

Thanks for your input

No. The mold in the corner of the room has completely different causes.

What are the reasons for mold appearing in the corner of the room or near the window?
I would appreciate any advice!

That will be the coldest corner of the room, which is common in external corners of houses. Add moisture and insufficient heating, and you get mold. It can be resolved either a) by increasing heating and ventilation or b) by installing internal insulation.
More airtight windows can make the situation worse.

You need to assess how the situation is in your case.

Or was there a cabinet or something similar standing there?

Yes, there was a cabinet about 5cm (2 inches) away. The issue can be resolved by increasing the distance. The question is also why there is mold or always condensation on the windows. The house is approximately 30 years old.
