Do the temp. vents you advertise close once the temp. rises above 70 degrees? I need some that will do that so condensation will not occur.
Ours will open fully around 72 degrees or higher. Once you get below 70 degrees, they will start to close. At 38 degrees, they will be completely closed. For most applications, this allows warm air to escape. Heated air expands and if there is moisture in this air, it’s more likely to cause problems so allowing it to escape is generally the smart thing to do. Trying to trap the air is not what they were designed to do so I don’t think our Temp Vents will help for your need. Additionally, I don’t know of any such design which seemingly works exactly the opposite of all the ones I know exist today.
