Americans have worse problems than us with -30 ° C in winter and + 40 ° C at 100% humidity in summer (around Chicago for example !!) with all wooden houses and appalling termites (and gardens crammed with m3 of dangerous insecticides!)! !

Many of the air-conditioned houses have rotted because the outside at + 38 ° C at 100% humidity condenses on the inside walls air-conditioned at + 28 ° C to death and all the wood rots !!
The vapor barrier must be inside in summer and outside in winter !!!!!!
