What is the Best Home Insulation?

Home insulation comes in many forms. To find the best insulation for your home you need to decide:

  1. Where you will be adding the insulation
  2. The R-Values recommended for those areas

What is R-Value?

R-Value refers to the thermal performance of the insulation. Proper installation is highly important, as it will affect this value and the insulation’s ability to perform at its best.

Can I Insulate My Own Home?

Of course. Although we don’t recommend that you do, you can follow manufacturer’s guidelines to install your chosen materials.

In our honest opinion, insulation should be properly installed by a professional to ensure the peak performance of the materials.

DIY Inspection – Checking Attic Insulation Levels

Before heading into your attic, you will want to prepare yourself for the adventure. Here are some basic tools you will likely need:

  • Safety glasses, gloves and a dust mask
  • Flashlight or Head lamp
  • Hard hat or cap to protect your head from exposed nails
  • Measuring tape
  • Wood slats to walk on if necessary

WARNING: Vermiculite insulation may contain asbestos. This type of insulation is a lightweight, grey material resembling small gravel. Do not attempt to remove this or inspect further if you find your home contains this material. Contact your local health department to learn what steps to take.

Upon inspection of your attic, if you see that the insulation is level to or below the joists you will need to add insulation. If the joists are buried beneath the insulation you likely have enough and don’t need to add any more insulation.

Make sure that the insulation is distributed evenly throughout. Often, the center of the attic is properly filled while the eaves aren’t full enough.

You can also find manufacturers recommended levels and R-values printed on existing fiberglass batts or use a measuring tape to measure the depth of the insulation. You can use the table below to calculate the R-Value.
