How to Insulate a Floor

Foam is found in can i use loft insulation under floorboards and chairs, mattress pads, children’s car seats, shoe soles, building insulation and much more. It is an extremely useful insulator as it absorbs heat and cold from the air, making things warmer or cooler. Foam is also quite lightweight, making it easy to move around and fit in spaces where other insulation would not be practical.

There are several different ways to insulate a floor but the best method is to spray foam under the flooring to create an air seal and prevent energy loss from the floors in your home. A professional contractor will be able to determine the best solution for your situation, especially if you don’t have an access hatch underneath the floorboards or a crawl space.

Maximizing Efficiency: Insulating a Floor the Right Way

One way to insulate a floor is to push quilt-type insulation into the gaps between the joists from below and then attach it with netting or tack strips. This is a difficult process because it requires lifting the floorboards, which is often impossible in homes with period or historic wooden floors that are highly valued for their aesthetic and historical value. It is also not an option if you want to avoid destabilizing the joists and sleeper walls below.

Another method of insulating a floor is to install rigid foam panels under the floorboards that have an attached vapor barrier and can be cut to the size of the joists to provide the desired thickness of insulation. If you are using this type of insulation, make sure that it is compression-grade and not face-grade, as this will help to prevent the vapor barrier from deteriorating over time.
