3 Basic Things to Consider when Insulating an Old House

Insulating an old house is one of the significant problems that homeowners deal with. Owning an old home can be a luxury and a potential investment with a massive payout for people who know how to play their cards right. Even so, one of the many reasons that people opt to sell their real estate properties is the numerous inconveniences and improvements that older properties need.

Insulating an Old House

One of the many disadvantages that older homes have compared to more modern residential properties is the severe lack of insulation. Some households require a major overhaul just to have a proper heating system installed. However, you don’t always need to make a complete makeover to make your home more comfortable to live in. In this article, we will give you some key pointers on how to improve insulation in old homes.

1. Installing a floor heating system

A major drawback of owning an old home with no proper insulation is experiencing the cold winter days. Your casual indoor outfit might need an extra two or three layers just to survive the low temperatures. One effective way to provide uniform protection to your flooring from the changes in the weather is by applying spray foam insulation on the underside of your floor. It works to add both insulation material and an effective sealant to keep heat in and the cold out.

Spray foam treatment is merely the first step to warming up your floors as its main purpose is to regulate the existing room temperature. When insulating an old house, consider installing an electric floor heating system is a compact and energy-efficient heat source that can be used to warm your floors.

2. Increasing ventilation through the attic

One of the least expensive technique to insulating an old house is something that you can do all by yourself. Treating your home with spray foam is an excellent solution for a spacious area. Attics are typical to vintage homes to serve as storage space for various furniture and equipment in place of modern storage shed. You can fit up to 25” to 30” of loose-fill insulation under your roof due to the attic’s relative size.

You could also attach better ventilation while you’re improving the attic’s insulation. Ridge vents are a better fit compared to the typical mushroom-style vets that can be seen on top of modern homes. They’re also easier to retrofit in an existing roof without having to overhaul the entirety of your roof shingles

3. Reinforcing wall insulation

Most halls for vintage homes aren’t built for extreme cold or intense levels of heat. This is primarily because the weather conditions back then aren’t as high and as low as they are now. Many old houses have hollow walls that contain wood shavings in place of properly insulated materials.

Installing insulation sheets that face your exterior walls then adding a new layer of drywall on top makes for an effective renovation of your old walls to be practical defenses against the heat and cold. Make sure that if you’re going to improve insulation to your basements that you make sure that it’s always dry, as pipe leaks paired with wet walls can lead to mold growth.


One reason that homeowners are too reluctant to move away from traditional homes is their increasing value. As more and more properties are looking to create budget-friendly homes for first-time buyers, the quality and number of vintage homes are facing a decline. As more homeowners look to sell their property and their dated homes, the higher the demand will be for older homes that can have modern features and amenities.

Renovating your home to increase its value in the market is a common practice for people looking to earn a considerable profit.
