Building in fresh air vents

[robbannnnn]

Hello,

I have built in all the old traditional air vents in all the rooms of a 1920s house and installed new triple-glazed windows with air vents in them.

Did I do this wrong... should I expose them all again?!

Who do you contact to measure the air, etc.?

The holes and grills are still on the façade outside, so the possibility is still there...

Yes, you need to have ventilation in the rooms. Especially since you have installed new tight windows.

Yes, you need ventilation in the rooms. Especially since you've installed new sealed windows.

Yes, but as I mentioned, I have installed triple-glazed windows with trickle vents... maybe those aren't sufficient?

If you have trickle vents, it should be okay, but it depends on the rest of the system. Are there exhaust fans in the house?

I don't think it sounds like you've done anything directly wrong. If new triple-glazed windows with trickle vents have been installed, that can absolutely be sufficient, provided that the rest of the ventilation in the house is working well.

In older houses, especially from the 1920s, ventilation was often natural draft via leaky windows and chimneys, so when you install airtight windows, the balance changes a bit.

The most important thing is really that there is good exhaust air in the kitchen and bathroom. If that part works, trickle vents usually work just fine!

Are there exhaust fans in the house?

Yes, there are in 2 bathrooms and in the kitchen.. but they don't run all the time.

I don't think it sounds like you've done anything directly wrong. If you've installed new triple-glazed windows with slot vents, it can definitely be sufficient, provided the rest of the house's ventilation is working properly.

Is there a way to measure that you have good circulation in the house?

Now, this isn't exactly an answer to your question, but... I installed Pax fans in the shower and bathroom that always run on low speed and activate when it gets humid or someone is in the room. In the kitchen, I installed a kitchen fan that always runs on low speed. Then I have some slot vents and a couple of regular fresh air vents. It resulted in a completely different climate in the house, very fresh, with no significant impact on the electricity bill.

Then if you have radiators under the windows, air supply there is preferable.
