How to Insulate Floors and Ceilings

Why install insulation in floors and ceilings?  Insulating floors and ceilings is a key step in building a protective thermal layer around a home and maximizing energy efficiency. Adding insulation to both interior and exterior walls and ceilings helps protect the rest of homes from damp or cold basements and can reduce noise between different floors and rooms. 

The below video offers step-by-step directions for effectively insulating floors and ceilings. 

How to Insulate Floors and Ceilings

Insulating your floors and ceilings is a key part of building the protective thermal layer that brings your house to maximum energy efficiency. Don’t worry, learning how to insulate floors and ceilings is probably simpler than you thought. Adding insulation to these spaces also helps to protect the rest of your home from a damp or cold basement and can dampen noise from different floors of your house. In this video, we’ll take you through the steps involved in effectively insulating your floors and ceilings and make you sure you know how to insulate floors and ceilings on your own. Precut fiberglass batts are the easiest way to roll the insulation into the cavities between the layers of your home, and some kind of thermal barrier layer, like drywall or Kraft-faced insulation, is important when installing this insulation. It’s important to use some kind of fastener to keep the insulation in place, but be sure not to over-compress or you’ll lose valuable insulating power. With a few essential guidelines, insulating floors and ceilings is a straightforward and easy way to improve the overall energy efficiency of your home and tighten the thermal blanket that keeps you cool in the summer and warm in the winter.

Precut fiberglass batts can be easily placed into wall cavities and ceilings between the layers of a home. Use insulation that provides both thermal and sound performance, like JM Formaldehyde-free™ fiberglass insulation.

Use a fastener to keep the insulation in place but be sure not to over-compress or valuable insulating power will be lost.
