BAYS sliding poorly waterproof at the bottom.

[LOGIC12]

Hello, We note that the sliding windows, very practical elsewhere, have a seal that leaves much to be desired compared to PVC window doors.
There is a possibility to improve both the airtightness but also the soundproofing, taking inspiration from this video:

We can also do the same thing on the sides vertically, it cuts the cold much better and also the noise.
We sometimes use a thicker glass on the outside to cut the noise better, but all the noise does not pass through the glass, but also through the sides.

For the top, we leave it as is.

It is necessary to be careful when it is badly exposed (wind which throws the rain) to clear the flows for the rain in the bottom towards the outside.).

The ventilation of the VMC air must be done by ventilation in the top of the bay (dry rooms) and not all around.

So for all intents and purposes ....
