What if someone told you that they could build a house that would last 500 years? Would you believe them? Matt Risinger takes us to a home that is built with a "perfect wall", the type that is so durable it can last many generations and stand up to the elements. Specifically, it can stand up to the main enemies of home durability water damage, air, and thermal effects. The best way to hold up against these main house enemies are control layers, for instance insulation. The best way to control heat and cold extremes is insulation from the outside, not inside. Air control is another focus that impacts durability. So air flow needs to be filtered via air control. Watch the full video to see what the perfect recipe is for a house that stands up to time itself.
