#physics **On the physics of thermal windows** Now that California and the UK must join us Canadians, we need to discuss new windows for the masses. Our old single-pane windows rattle in their frames, and leak like a sieve.
The greatest benefit you can have is by sealing your house. In winter, a leaky house has 20% humidity that kills you. An over-sealed house has 60% which causes the windows to rain, and produces black mold. You want a time in the winter with 40%, to kill all the little orgasmisms. (sic).
The glass sandwich has about a total effect of 5%, yet it is the big selling point. You want casement windows that seal like a fridge. You don't need triple pane unless you live by the train.
