Explain capillary tubes and breather tubes in windows?
I’m buying windows for 6000 feet and being told a variety of things from manufacturers about whether capillary tubes or breathing tubes or balloons are needed. Some say yes, some say no. Can someone explain to me exactly how these things work because I don’t quite understand how they equalize pressure without letting the gas out.
For reference I’m talking about Passive House rated windows R6-R8 triple pane with argon. CZ 6B
