Oct 27, 2023 · I saw the tiktok you’re talking about today, it’s basically air that hasn’t moved and circulated much or air that’s mostly carbon dioxide. Very bad for you, but pretty uncommon in abandoned buildings from what I know.

Dead air underground is a hidden danger that can pose serious threats to the health and safety of anyone who enters such a space. By understanding what causes dead air underground, what are the risks of exposure, and how to avoid or minimize them, you can protect yourself and others from this hazard.

For many years buildings have been built with an air space between building cladding and batt insulation in wall cavities. This air space did, in fact, help circulate air inside the wall and ventilate humidity through the wall.

Nov 1, 2009 · Is there an R factor to such a temporary treatment to a stud wall? You have to figure out a way to prevent convection currents from flowing in the dead air space for it to have any value. This is actually how fiberglass bat works- …

Aug 31, 2012 · If the gas is air, the optimal gap size is about 1/2 inch. If the gas is argon, the optimal gap size is a somewhere between 1/2 inch and 5/8 inch, depending on the outdoor temperatures you are designing for.

Mar 22, 2025 · Dead air spaces should be analysed and avoided, to optimise your safety and wellbeing in the event of fire. Follow these tips, but also make sure you check other resources and consult with professionals.

Aug 4, 2023 · If we are talking about a normal building that is not totally sealed off — we will most likely see chimney effect air flow during daytime, where as the sun heats up the building, hotter air rise and escapes from creases that are near the top of the building, and cooler air flows into the building near ground level.

Dec 4, 2024 · If you're at the threshold of bad air, the lighter if lit above the threshold, it will continue to burn below the threshold, but the flame will be separated from the lighter. Here's some good info from a caving perspective.

Nov 29, 2015 · Essentially it is his belief that more dead air space would help isolate low frequencies over more insulation. Since insulation does little to block low frequencies, dead air space would give me more low end isolation.

Feb 22, 2011 · One answer lies in the size of the dead air pocket and has a good, sciency name attached to it – convective loops. If you’re thinking about your middle school science class and the three forms of heat transfer – conduction, convection, and radiation – …
