Northbrook, IL Spray Foam Insulation

Spray foam insulation is one of the newest insulation products available. Spray Foam has gained popularity lately due to the benefits it offers compared to traditional fiberglass insulation. 1) Spray foam offers more insulation value (or R-value) per square inch, meaning less insulation is needed to get the job done. 2) Spray foam expands when it is applied so it also air seals gaps and cracks that may go unnoticed. 3) Spray foam insulation is waterproof so it stops mold and mildew growth which can be a major problem for fiberglass insulation. 4) Lastly, spray foam insulation is foolproof. Spray foam will never shift or slide after it is applied so you will always have the peace of mind that your home is properly insulated. If you think spray foam is right for your home, contact us today to schedule your FREE estimate!

Benefits of Spray Foam Insulation Include:

  • spray foam works in all areas of the home
  • has a greater R-value
  • acts as an air sealant
  • is waterproof
  • leaves no gaps

It is our second year in our house and we have been concerned with it being too cold or too hot. It seems like our AC and furnace always have to run. Rooms still feel cold. We don't know what the cause of the problem is. Is it windows not insulated or is it just whole house insulation? We would like to pinpoint the problem so that we can solve it before our new baby is born.
