Concrete block house from 1904
I have a home in northwest Ohio. The home was built in 1904. The construction is concrete block.
I have converted the home into two rental units. I have two boilers
the lower unit has a 100,00 btu boiler and the upper unit has an 80,000
byu unit. both boilers have a single loop. My problem is when the temperature
drop to 15 deg. I can only get the building up to 59 deg’s.
I have replaced all the windows with insulated glass.
I am thinking about installing a foam board type of insulation on the inside of the building
can you recommend a product?
I am concerned if I use a board foam insulation I will trap moisture between the wall and the back side of the foam board.
Can you give me some advice?
