I live in Canada where we use a lot of insulation in our homes. I'm wondering why we don't just suffocate in the winter time or can the oxygen we breath permeate the walls of a house?

Modern heating and cooling systems are designed to bring in a certain amount of fresh, outside air as they run. That's because newer houses are nearly airtight. The air would get really bad pretty quickly otherwise.

U are deceived some how.
20.9 % normal oxygen level
19.5% the lower safe limit ,just below this and u will pass out.
The limits are pretty tight and is why u should not lay in the floor as most of the dangerous gases are so heave they suffocate u.

Houses are not completely air tight, but they are tighter than they used to be. There is a real concern about indoor air quality today as a result.

unless it is a non porous substance the answer is yes...all building materials are porous in the general construction of a home
