Exterior Insulation Guide: Cold Climate

Everything* you need to know about wrapping old homes with cold bones: climate zones 5, 6, and 7

Adding insulation over the walls and roof makes a continuous thermal barrier while burning your thermal bridges.

It includes replacing the siding and roofing and detailing the windows. 

Wrapping a house in foam can also cause headaches if not done thoughtfully: make sure that the air, water, and thermal barriers are working together, not against each other.

Trapping moisture in a tight house means #BugsMoldRot
