Insulating old brick home
My house was built in 1904 and made of brick with no insulation in the walls. What is the most cost effective way to insulate without tearing out the interior walls to cut down on the heating bills. We recently replaced windows on the 1st & 2nd floors with the 3rd floor still to be done. The windows helped but it still gets too hot in the summer and cold in the winter. Any suggestions are greatly appreciated.
Re: Insulating old brick home
If you intend on adding insulation from inside you might be looking at either cellulose or fiberglass blown into the walls or possibly liquid foam injection. This would involve a minor invasive method of drilling holes in the walls to inject whichever insulation. This would require some patching involved but it's less than tearing out the walls completely.
This is providing that there is no knob & tube wiring existing in these walls because you can't cover this type of wiring with insulation.
The other alternative would be to cover the exterior with sheets of rigid foam then cover with some sort of finish.
