All You Need to Know About Home Insulation

Apr 25, 2018

You should be paying attention to what is behind your walls. Proper insulation in your home means a comfortable, healthy living. In addition to warming your home during winter and cooling it in summer, proper insulation reduces your energy bills, keeps unwanted noise out and even prevents mold growth. To properly insulate your home, you should start from the roof and make your way down to the foundation.

Insulation works by keeping outdoor air from penetrating to hour home interior and the conditioned air inside from escaping out. This is done by trapping pockets of air thereby slowing down how air moves in and out of your home.

Insulation Ratings

Insulation rating depends on the measurement of the resistance of the insulating material to movement of heat, typically known as the R-Value. The more effective a particular insulation is, the higher the R-value.  Local building codes list will recommend R-Values for the different areas of your home.

Signs of a Poorly Insulated home

  • Cold floors and walls during the winter season
  • Hot air inside your house in the summer
  • Unusually high energy bills
  • Mold growth
  • Ineffective cooling or uneven heating

Types of Insulations

When it comes to insulation, there are many different types to choose from. Which type of insulation you choose should be based on which part of your house you are insulating and the R-Value required. Below are common types of insulation used in homes:


This is the most common type of insulation. It has an R-value of 3.0-3.7 per inch. It is also very easy to install. Fiberglass batts for attic insulation are very useful and if properly installed to the ideal depth will comfortably insulate your home.

Mineral Fiber

Mineral fiber in batts, like fiberglass, is easy to work with. It is readily available from most home improvement contractors. It has a slightly lower R-Value of 2.8-3.7 per inch. Despite the lower R-Value, mineral fiber offers better fire resistance and sound-proofing capabilities than fiberglass.


This is a loose-fill material. Since it is denser than fiberglass and mineral fiber, it is mostly used in attics. Consider hiring a professional to install cellulose insulation.

Spray foam

Spray foam is becoming popular for home insulation these days. There are generally two major types of spray foam: closed cell polyurethane and low-density open-cell polyurethane. Closed cell polyurethane is the recommended choice for attics and exterior walls (it has an R-Value rating of 5.5 – 6.0 per inch).

Quick Tips on Insulating Your Home Effectively

  • Locate where the problem is
  • Check the R-Value of the material
  • Choose the right type of insulation for your home
  • Seal all the windows and doors
  • Seal vents and duct
