Do your windows also run on condensation when the summers humidity is high or the temperature drops outside? Ours no longer does.
Inner panes
In our wheelhouse there are a total of 13 windows with an area of 3-4 m2. Over several years, we have tried with inner panes made of 4 mm lexan.
The insulation performance of these inner panes has been excellent, but we had quite a few problems with mist between the panes. To absorb the moisture (dew) between the panes, we placed a small bag with silica stones.
We have had two types of inner panes:
- Panes that were screwed to the frame with a sealing strip between them. In these panes, the silica stones had to be dried approx. every second week.
- Panes that were fixed using magnetic strips. These panes were more leaky than the panes with sealing strips. In these panes, the silica stones had to be dried once a week. In addition, we had quite a few problems getting the glue on the magnetic strips to hold.
The bags with the silica stone are dried in the microwave on the lowest setting. (15 minutes for 15 bags of 7g.

Both types of inner panes went beyond the aluminum frame, so we avoided moisture on the frame.
Double glazed windows
We now have replaced the windows in the wheelhouse with double-glazed windows, which are fixed in a frame made of PVC. The frame is relatively thick and insulates exceptionally well. Expensive (well over DKK 60,000) for 13 windows, of which the front 4 are in 8 mm toughened glass on the outside and the rest in 6 mm toughened glass on the outside. All are in 4 mm toughened glass inside. But really good. We have enjoyed a winter with no moisture on windows or frames, and good heating comfort. In addition, we also had a window made that can be opened, which we already have benefited from many times.
For the small windows in the boat, we continue with lexan inner panes (now screwed on). Since these windows are significantly smaller, the moisture problem here is not quite so big.
The double glazed windows were made to order from a Dutch company: Topwindows
