3 Mistakes in Attic Insulation Installation

Whether you are doing insulation installation yourself or hiring a professional

Insulation is one of the most important things in your home. It helps your home stay warm or cool, depending on the season, and helps keep your electric bills low. However, like anything else, you have to be careful when getting insulation installed in your home to make sure that it is installed properly. Below are 3 mistakes that are commonly made when it comes to attic insulation installation.

  1. Existing Insulation Has Gaps

Insulation will stop heat flow. So, even when there’s a tiny space in between the floor of the attic and insulation, it can affect its ability to insulate. If you’re finding that there are gaps, fill these open areas and ensure the insulation’s completely contacting the floor of the attic. You may also be able to call the company who did your insulation installation so that they can come back and fix the mistakes they’ve made.

  1. Insulation Covers Eave Vents

Properly ventilating your attic helps with preventing condensation, mold and even damage to your home’s components. You want to be sure that insulation isn’t covering your eave vents. This can be done by installing some ready-made baffles in between your roof rafters. This is going to help with keeping your airstream open and preventing your loose fill from moving around.

  1. Improperly Sealed Knee Walls

A knee wall is a short half wall in your attic. If your attic is insulated, the opposite side of your knee wall usually isn’t. if your wall has cellulose or fiberglass insulation on the wall’s opposite side, you should cover it using something like drywall. You also should seal any penetrations in this wall just like you would with exterior walls.

Whether you are doing insulation installation yourself or hiring a professional, make sure that you are avoiding these mistakes. Avoiding these mistakes can help your home be more comfortable no matter the season.
