Importance of Basement Insulation

Although the walls of your Basement Insulation are substantial, the concrete itself could be a more effective insulator. It makes sense to insulate your foundation walls to improve energy efficiency because your basement is a conditioned environment in your house. Any mechanical equipment in the basement may increase its lifespan by insulating the space around it. When the temperature is steady, your furnace or water heater won’t have to work as much.

A high R-value, a measurement of a material’s resistance to heat movement, is crucial when selecting insulation. The Department of Energy offers R-value recommendations depending on your home’s location and fuel type to help you choose the appropriate R-value for the insulation in your basement and other parts of your house.

You might be overpaying for energy and, worse, allowing mold to grow in your basement if your basement isn’t properly insulated. Making it necessary to get mold removal services. Take the time to look into your options if your basement lacks insulation before the chilly winter weather arrives and your energy costs rise.

Benefits of Insulating your Basement

Insulating your basement has many benefits, as you might have figured out and there are many different types of insulation to choose from. So let’s list them down for a more comprehensive idea.

  • No more wintertime chilly flooring
  • Increased stability of indoor temperature
  • Decreased ‘stack effect.’
  • Less expensive heating and cooling
  • Fewer drafts inside

Types of Basement Insulation

When we talk about basement insulation, we talk about its walls, ceiling, and floor. For each area, the type of basement insulation varies, and it is important to employ the best one for good results. The following context shines more light on this.

Insulating your concrete floor

Here is what we do to give you insulation for your concrete floor:

  • Insulation of subfloors
  • Using rigid foam boards that are ready for flooring. (If you don’t prefer plywood or OSB, this is a good alternative made up of hardened foam that fully supports the flooring)
  • Using basement floor panel insulation that comes with an integrated OSB top layer
  • Using electric underfloor heating.

Insulating your basement walls

The basement wall insulation is the best type you will need and serves as the optimum solution since your home is most susceptible to fluctuating weather in your basement, including moisture incursion, cold air drafts, and the transmission of cold temperatures through the stone, brick, or concrete walls of your foundation. You can choose blown-in insulation for this purpose.

Instead of just keeping those unwelcome temperatures from reaching the floors of your house, you are stopping them from entering your living space in the first place by insulating the walls of your basement.

Spray Foam
The best type of insulation for moist environments like basements is spray foam. Spray foam with a closed cell structure is ideal for “locking out” water vapor that naturally seeks to go from moist basement walls into finished basement rooms.

Sill Plate & Joist Boxes Sealing

The intersection of the floor joists and the sill plate, or the top of the basement wall, should be the first major area of insulation attention. This region has to be sealed with insulation because it frequently leaks and conducts heat. Spray foam insulation works as intended and is applied to these areas to instantly air seal and provide a productive high R-value insulation.

Foam board

The use of foam board products is the second-best option for insulating basements. This is the approach we choose most frequently, and most do-it-yourselfers are comfortable with it. It is a desirable alternative because it is significantly less expensive than spray foam. Since many different foam board products are available, we advise you to read Foam Board Insulation Types and R Values for a quick primer on the materials.
Hybrid Foam & Fiberglass Insulation

With this technique, a layer of foam board will be installed and sealed, as previously said. The wall in front of the foam board will be framed with steel or wood since there isn’t much difference. Then we will install fiberglass insulation in the stud cavities.

Vapor Barriers

To stop moisture from permeating basement walls, contractors frequently employ polyurethane sheeting as a vapor barrier (they are particularly useful for crawl space encapsulation). Before adding plaster or drywall, the material is attached to the basement wall’s frame. A vapor barrier can help keep a basement warm and well-insulated.

Insulating the Basement Ceiling

Insulating your exposed foundation walls is your best option. Use water-resistant insulation like closed-cell spray foam or XPS foam board after addressing any moisture problems. The material that most homeowners choose has the potential to trap moisture.

Annette Casatelli

I received a few quotes to get the walls in my home filled in with blown in insulation. Zavza Seal was affordable and they did an excellent job.

They were very concerned with cleaning up, which I appreciated. I felt the difference in my home immediately. No more freezing cold walls. I recommend them, hands down.

Ellen Szuchmacher

Efficient, courteous and responsible workers. The job was quoted as being completed in 2 days but more work was required and they returned on the 3rd day and completed the job without additional charges. They reinsulated my crawlspace (not an easy job). I recommend Zavza Seal without reservation.

Couldn’t be more satisfied with the job Zavza Seal did. Brendan and Jake were accommodating, fair and extremely knowledgeable. Their team worked incredibly hard that day under difficult conditions and did a great job. I manage a multi-unit HOA and we will definitely be using them again.
