The best way to insulate your interior walls without removing drywall involves filling the interior walls with blow-in insulation. While blow-in insulation is typically used in attics, basements, and other crawl spaces, it works perfectly behind established walls to create a solid barrier for thermal insulation.
How do you insulate a brick wall from the outside?
Install rigid foam sheathing directly over the brick wall with fasteners or furring strips. Make sure there are no air gaps. * Caulk or spray foam any air leaks and joints, taking special care to cover any areas that could potentially cause thermal breaks or moisture concentrations.
Can you insulate a single brick wall?

Do brick walls need insulation?
Although bricks have natural insulating properties with an R-value of around . 80, it’s not nearly enough. Insulation along with brick is the best way to insulate a home and lower energy costs. The type of insulation you should use may vary depending on the age of the house and how it was built.
Are double brick walls insulated?
As most double brick cavities are only 50mm wide, there is only so much insulation material you can inject into the cavity space. Uninsulated, a double brick cavity is rated at R0. 4, and once insulated, it becomes R2.
Why is there a gap between brick and wall?
It’s traditional for masons to leave 1″ of air space between the back of the brick and the framed wall. Brick and mortar are naturally porous and WILL LET WATER pass through, so this 1″ air gap is vital to drain the moisture out of the cavity. This airspace is hugely important.
