www.protradecraft.com | SUBSCRIBE please • Insulating solid masonry buildings can be tricky. • If the brick can’t breathe, the insulation can cause spalling, efflorescence, and other types of moisture damage • A fibrous drainage mat can create an airflow cavity between the brick and a layer of spray foam insulation. • Drainage mat with built-in bug screen is best, otherwise install insect screen against the brick first • A layer of house wrap keeps the spray foam out of the drainage mat. • A framed wall set out from the house wrap will allow the insulation to be continuous along the wall and leave room within the studs for wiring. • Of course, drywall goes on the inside of the studs. • For any water that is driven into the walls from rain and sun, 1/4 inch holes are drilled angling down to the outside to provide drainage at the floor level. • At the top of the wall, insulation should completely cover the rim joist. • Multiple layers of breathable sheet goods provide a ventilation space with drainage and a surface for a spray foam to make an energy efficient masonry wall that can thumb its nose at moisture. • Twitter: @TradeCraftsman | twitter.com/tradecraftsman • Pinterest: @ProTradeCraft | pinterest.com/ProTradeCraft/ • Facebook: / protradecraft • Subscribe to Pro Trade Craft's YouTube channel for regular updates
