As a word of advice, if want a Faraday cage because you want to to protect yourself from electromagnetic hypersensitivity, then by all means, knock yourself out following those directions. Preferably not literally, because, as noted in the links, lack of airflow will hurt you rather more reliably than EMI. But if you want to actually keep EM radiation in or out in a measurable way (and WiFi sensing is the epitome of measurability), then I recommend learning about shielding from a professional. Professionals, by and large, don’t believe the electromagnetic hypersensitivity exists, at least not in the form that those webpages discuss.

What does EMF shielding (for security or any other reason) have to do with airflow? Radiant barrier is perforated with small holes for airflow, which don't affect shielding performance at lower frequencies like 2.4Ghz/5Ghz, which can pass through walls. mmWave Wi-Fi radar (e.g. 60Ghz 802.11ad) doesn't propagate well through walls. There is conductive mesh for open windows and some existing window insect screens are made of conductive material that effectively blocks EMF. Indoor air quality can be monitored, with or without EMF shielding.

  The mpkb.org link discusses rather small faraday cages like this: https://www.marshallprotocol.com/images/Building_a_DIY_Faraday-Cage.pdf https://www.marshallprotocol.com/images/Building_a_DIY_Farad... Look at the awesome picture on the very top left. That’s a tent made out of Mylar or a similar material. You can’t monitor the air quality inside with modern technology because that would pollute the interior EM environment, thereby defeating the purpose [0]. I like fresh air in my room, TYVM. [0] Of course you could use a fan outside to move some air through a mesh and sample it, and you should if you’re going to live in this thing, because IAQ is important.
