Hello,
I am currently planning a major renovation. A key concern for me is room ventilation.
At the moment: the bedroom is about 12sqm (130 sq ft) in size, with two people using the air. Especially in winter, when the windows are closed, I feel like I’m suffocating. Either I wake up at night and have to open the window for a few minutes, which disrupts my sleep, or I have to tolerate the uncomfortable stale air in the morning.
In winter, a tilted window is not an option, and in summer it’s also quite impractical because an air conditioning system will be installed later. Leaving the door open to get fresher air from other rooms won’t be possible after the renovation (and even now it’s not fully satisfactory). Specialized soundproof doors with sealing strips that extend at the bottom when closed will be installed.
Challenge:
- Currently: airtight room, no supply or exhaust air.
- Solutions must not be visible from outside (prohibited by the homeowners’ association), so all the usual decentralized ventilation systems with heat recovery on the market are not an option.
Since I don’t have to comply with energy-saving regulations or similar requirements for my old apartment, heat recovery is not absolutely necessary.
Each room has a shutter box that I could repurpose. From the outside, there is a fiber cement panel in front, so any openings would remain hidden. I had already thought about installing a surface-mounted bathroom exhaust fan or something similar in this box. All fans I’ve found in this category are exhaust only—I cannot find supply air or reversible units.
The next problem: supply OR exhaust air alone is not sufficient. I need both for proper ventilation.
I feel like I’ve searched the entire internet, but I can’t find compact, quiet surface-mounted fans available in both supply and exhaust versions. My idea was to install one fan on the far left (blowing in) and one on the far right (extracting air). I am aware that this is not optimal. However, even with a "ventilation short circuit" inside the shutter box, a mix with fresh air would occur, and I might be able to "direct" the supply air within the room. The whole system could be controlled by timers or sensors.
Where can I find suitable hardware, or has anyone faced the same problem and has a better suggestion?
Regards

Doors with special sound insulation requirements are installed, featuring a sealing lip at the bottom that extends when closed. These are also available with an air transfer function (e.g., Planet Mine drop seal), allowing cross-ventilation through the apartment. You might also find Innoperform air transfer seals for interior doors of interest. Additionally, there is a range of sound-insulated air transfer elements designed for wall installation. This can potentially enable a system where fresh air is supplied to the bedroom and exhaust air is removed via the bathroom.
In my opinion, simply opening and closing the bedroom window will not achieve the desired effect.
