Is it Cost Effective to Insulate?
The right insulation system can save you money, reduce the amount of energy you use and make your home more comfortable. The local climate has an impact on the cost-effectiveness of any insulating project.
Analysis
If your home is poorly insulated, it usually pays to upgrade the insulation. If you are building a new home, it makes sense to insulate well now, so you don't need to retrofit later.
