Struggling with high energy bills in an older home? The problem most likely has to do with too much airflow.

While most insulating materials are great at stopping heat conduction, they are not designed to prevent heat convection (i.e., airflow). As a result, you could be experiencing air drafts and still hear everything behind your walls with little to no insulation material inside of them.

Injection Foam insulation is a cost-effective material designed to re-insulate older homes, even if the wall cavity is partially filled with old, ineffective insulation. By creating an air seal, the insulation foam injection material can prevent airflow, trap noise, and limit heat transfer to eliminate cold drafts during the winter.

How Insulation Foam Injection Works

Injection foam flows through empty spaces and across old material to fill the wall cavity, barring heat convection and conduction from occurring. In turn, the foam creates an air seal that insulates your walls fully and increases its R-value.

Injection foam consists of an environmentally safe resin material that’s mixed with water and a foaming agent that allows it to expand easily. However, once inside your walls, the material will settle and remain still through its lifespan.

How Foam Injection Is Installed

EnergySmart features a team of professionals ready to handle all your insulation needs. The process is simple: our team will remove a panel of siding, drill a hole into your studs, and then inject the foam material into your walls, where it will fill in any space available to create an air seal. 

Our foam injection material can be used with any type of siding, including vinyl, wood, aluminum, concrete, and brick. Depending on your type of siding, injection foam can be inserted through the interior or exterior of the home. In some cases, such as concrete, multiple holes may need to be drilled into the siding to allow the foam material to be installed. Nevertheless, injection foam is the perfect solution to insulate Concrete Masonry Units and hollow walls in new construction and older homes.

Benefits of Foam Injection Insulation

Foam injection insulation is designed for older homes and new constructions with very little existing insulation in the walls. Instead of tearing apart your drywall to hang new fiberglass batts, injection foam can be inserted through small openings in the studs to fill vacant spaces easily. 

This makes injection foam a very affordable alternative to many other insulating materials, including spray foam or blown-in fiberglass–though it may not be as effective as these materials. 

In turn, homeowners can enjoy many benefits from investing in foam injection insulation, including:

  • Lowered Utility Bills
  • Reduced Drafts 
  • Increased Home Comfort
  • Flexibile Installation
  • Unintrusive 
  • Reduced Risk of Mold or Mildew 
  • Noise Reduction
