If your home was built without insulation in the walls and ceilings then you're losing a lot of heat and money through the ceilings and walls.
The insulation will help keep the heat inside your home where it belongs and save you money on your heating bills.
My home was built without insulation years ago and I had a friend help blow some insulation into the walls and lay rolls of insulation in the ceiling and my house is now warmer and the heat stays in longer and my furnace doesn't have to run as often.
My gas bill before the insulation was $350.00 per month and went down to $150.00 per month so I save $200.00 per month on my heating bill which is quite a bit over the season.
