According to Mark Roemer Oakland, installing home wall insulation is one of the easiest ways to regulate the indoor temperature, and improve the energy efficiency. and lower the energy bills of your house. However, there are a lot of factors to consider when choosing wall insulation for your house.

The Details

Here is how to use wall insulation to improve the energy efficiency of your home:

  1. Understand the different types of wall insulation – There are broadly three different types of wall insulation, and each has its own benefits. These include:
  • Reflective coil insulation – This type of insulation is used to keep your house cool in hot weather. It involves insulating the exterior wall of the house by using a combination of a thin foil layer on the front and a plastic or paper at the backside. Such a setup helps to reflect the heat of the sun away from your home.
  • Foam boards – These are relatively thinner but offer high compressive and insulating strength. Foam boards work by preventing the flow of air or water to slow down the flow of heat.
  • Batts or blanket insulation – These are the easiest to install and are a popular choice for both interior and exterior walls. Blanket insulation contains millions of air pockets that trap air and prevent the flow of heat into your home.
  1. Consider the material – All insulating materials work great, but some perform better than others during certain circumstances. Thus, it is important to choose them based on your requirements. Here is a list of common materials used for insulation:
  • Rockwool – If you want to protect your home against fire, you can choose Rockwool. It is made from crushed rocks and is thus, non-combustible. In fact, it doesn’t produce any toxic smoke and also helps to prevent the spread of fire.
  • Glasswool – If you care about recycled products, glass wool should be your choice since it is made from recycled materials. Plus, it is easy to transport and install due to its high compression properties.
  • Earthwool– If you dislike artificial dyes or harsh chemicals, you should earth wool.
  • Polyester products – People with asthma or dust allergies should buy polyester products since they aren’t itchy to touch and have breathable fibers.
  1. Inspect the R-value – One of the most important factors that you should take note of when selecting wall insulation for your house is the R-value of the product. Typically, the greater the R-value of the product, the better it will be at resisting the flow of heat. Thus, whenever you are comparing different products, ensure you compare the R-value of the products as well.

Products with better R-value also offer better energy savings since they can regulate the health inside your home more effectively.


Mark Roemer Oakland suggests you familiarize yourself with the other benefits of installing wall insulation in your house. These include fire resistance and protection, noise reduction capabilities, and prevention of moisture build-up.
