ᐅ Residential ventilation system with parallel tilt window

Hello,

Since our homeowners’ association does not approve mechanical ventilation systems, I came across parallel ventilation windows. These windows open at set intervals, creating a 6mm (0.24 inch) gap all around.

My question:
Who is familiar with this technology and can tell me whether this is an effective way to ventilate living spaces?

Of course, heat recovery is not possible, but will the room be ventilated by this system when I am not at home?

Best regards,
Harald

Hello!

Even the manufacturer doesn’t claim this is an effective way to ventilate. According to that, the effect is comparable to a window left slightly ajar.

So it won’t actually provide air exchange – even a wall vent with 10 watts of power will probably be more effective (are those also prohibited, like exhaust dryers and/or kitchen range hoods?).

Some things seem to be reserved for a very exclusive group of users 😉.

So this won’t provide proper air exchange – even a trickle vent with 10 watts of power will probably be more effective (are those, like exhaust dryers and/or kitchen extractor hoods, also prohibited?).

Hello TOMTOM,

Which company are you referring to?
The company I have in mind has only positive feedback, and the product will be launched in August.

Hello!

I didn’t intend to advertise here – just ask "Aunt Google" 🙂. If the system isn’t available on the market yet 😕, who else could realistically answer your question?

I find a 6 mm (¼ inch) ventilation gap rather unconvincing. Anyone interested can calculate the available opening area. My cold frame is better ventilated 🙂.

Could it also be that YOU are trying to advertise here??

Hello TOMTOM,

If I wanted to advertise here, I would have named companies.

I am looking for alternatives because my housing community is not really a community and forbids me from breaking through the walls.

Best regards, Harald

These are standard trickle vents that virtually every manufacturer offers. They probably perform somewhat better than older windows with poor seals. Essentially, they provide a minimum level of ventilation but do not replace the need for regular airing by opening the windows. I’m not sure if the window is rainproof in this position.

Why don’t you just have rebate vents installed? While they also don’t replace manual ventilation, they ensure a certain minimum ventilation during absence.

Of course, a proper ventilation system cannot be replaced by a rebate vent.

Best regards
