Home Insulation Guide

Why should you insulate your home?

There are several benefits you stand to gain by insulating your home;

  • Sound control – home insulation tends to absorb noise that bounces off your floors and walls, protecting your home from noise pollution.
  • Energy efficiency –  insulating your home will save you a lot of money in energy bills.1 Air leaks from your attic, basements, and windows force your AC unit to overwork when it comes to controlling your home’s temperatures, resulting in higher energy bills.
  • Enhances comfort –  winters will be more bearable and summers a bit cooler. You won’t have to rely on the HVAC unit and extra blankets to keep your temperatures bearable.
  • Promotes a ‘green lifestyle’ – a properly insulated house ensures you use less energy hence fewer emissions. This, in turn, reduces your carbon footprint.2

Home insulation also increases the resale value of your house.

Types of home insulation

Here are some of your options for insulating your home.

  1. Rigid foam – this type of insulation is water-resistant, thick, sturdy, and is also referred to as insulation board. The main types of rigid foam insulation are extruded polystyrene, polyisocyanurate, and expanded polystyrene.
  2. Blankets and batts- it is the best type of insulation for DIY projects as it is easy to install. Blankets and batts are made from cotton, plastic, wool and fiberglass insulation.
  3. Loose-fill insulation- as the name suggests, this insulation is made of loose materials blown into insulation spaces.
  4. Sprayed foam insulation – this is where you spray foam all over an open space and after a while, the foam hardens, forming an impenetrable barrier. Spray foam insulation is perfect for hard to reach areas.

Which areas of your home should you insulate?

Some of the areas you should insulate are:

  • Attic  
  • Crawlspaces
  • Basement
  • Exterior walls and floors

Once in a while, check the insulated areas to make sure that there is no damage.

Pairing insulation with air sealing helps in controlling the amount of moisture in your home. Excessive moisture can result in mold growth which poses health risks to you and your family. Insulation that has also been improperly installed causes energy leaks and you may end up paying more in energy bills.
