When you live in an old home, energy bills can be astronomically high, thanks to poor insulation and older, inefficient furnaces. Owners of older homes often struggle with the question of what to do first: replace the insulation, or replace the furnace. In most cases, replacing the insulation is more effective in reducing energy costs, especially when polyurethane spray foam insulation is used in place of older, worn batt insulation.
Here's a look at a few of the benefits of replacing your insulation before replacing your furnace:
Installing new spray foam insulation is more cost-effective than replacing an older furnace, especially if replacing the furnace means that you'll need to have new duct work and exhaust pipes installed.
Older homes are typically not very well sealed. This means that a lot of dust and pollen blows in and becomes trapped in the old insulation. This debris ends up in your home's air supply, causing allergy symptoms for many. Polyurethane spray foam insulation forms a tight seal, so this debris does not enter your home. Thus, by replacing insulation first, you're doing both your health and your energy bill a favor.
Relief from Drafts
Another effect of poorly sealed structures is draftiness. Even if you replace the furnace, some areas of your older home will feel drafty and chilly. Spray foam insulation prevents this draftiness by forming a seal around your home.
Buying a Smaller Furnace
If you replace your insulation first, you may be able to get away with buying a smaller, less expensive furnace when the time does come to replace your furnace. With new insulation, your furnace won't have to work as hard to keep your home warm.
