How Efficient Is Installing New Insulation in Older Homes?

Did you know that around 90% of houses in the United States are underinsulated? Poor insulation is even more prevalent in areas that have a lot of older and historic homes, like New England.

But insulation is one of the most important aspects of your home when it comes to comfort and energy efficiency. Without adequate insulation, your home will never be warm or cool enough, and your energy bills will be much higher than they need to be. 

If you live in an old home in Vermont or New Hampshire, adding new insulation is one of the best energy-efficient home improvements you can invest in. Vermont Foam Insulation, the premier spray foam insulation company serving Southern Vermont and Southwestern New Hampshire, can help you retrofit your older home with new insulation, so you can enjoy modern comfort and historic charm. 

New Home Insulation Can Save 25-50% on Energy Bills 

In most homes, 49% of energy costs are spent on heating and cooling, and this number can be even higher when the home is underinsulated. 

Insulation helps slow down the transfer of heat into and out of your home. In the winter, it stops heat from escaping and in the summer, it keeps it from coming in. This makes it much easier for your HVAC system to heat and cool your home because it doesn’t have to make up for the constant heat loss or heat gain that occurs in an underinsulated home, leading to lower energy bills. 

With better home insulation, you could lower your annual heating and cooling costs by up to 50 percent! 

Where to Insulate for Maximum Efficiency in an Old House 

Attic and Basement 

Because of the way heat and air move in a home, the top and bottom of the house are the most important places to insulate. Upgrading your basement insulation or crawl space insulation and making sure your attic is properly insulated and air sealed will significantly improve your home’s efficiency, helping to maximize your energy savings.  

Walls and Floors 

Your walls and floors may also be insulated to protect against heat transfer. At Vermont Foam Insulation, we have many years of experience installing a new floor and wall insulation in older homes. We know what is the best floor insulation in old houses and how to blow in insulation in existing walls. You may be surprised to hear that you can install dense pack or foam spray insulation without tearing your walls down – this is for old homes with empty walls. Unfortunately, if walls are already insulated, that old insulation must first be removed. With an expert spray foam insulation contractor like Vermont Foam Insulation, insulating an existing home is possible and helps make your home more efficient. 

Find Out Where Your Insulation Is Lacking with an Energy Audit 

We typically start with a free estimate. However, a subsequent energy audit is one of the best home services to invest in if you live in an older home. An energy audit is an evaluation of your home’s energy efficiency that assesses insulation levels, air leakage, and more to see where the inefficiencies are located in your home. This is an important step when adding new insulation and will help you make the most efficient use of your home improvement budget as well as potentially qualify you for rebates.
