Question by bobby2g2002: Insulating House walls. Will it really help like they say.?
I live in a two story old farm house and they tell me if I get all the walls blown in with insulation it will save me 30% on my heating costs.Maybe even 50% I understand it will save me some but is it really that much?
Answer by David B
Yes it will. Any area in a home that can be insulated from the elements will increase efficiency.
