Floor Insulation - Cuts Some Dollars Off Your Energy Bills


With about 10% overall heat loss because of non-insulated floors, you will be paying your energy expense year in and year out. Your one-time expenditures for your floor insulation will certainly cut something sizeable from your energy expense all the way.   

If you’re one of those who are not aware of floors that are not insulated, there are different ways to know how to invest in your floors. For one, older homes usually have suspended floors. (There’s a space under it.) That is one way how heat is lost.

Those houses constructed around the 30s have concrete floors, which should be a smaller problem. Concrete insulation is done much easier with about a layer of solid insulation placed directly on the floor. Some houses today put polystyrene insulation below the concrete floor to reduce the heat loss.

Insulation

One of several ways to insulate your floor is using draught-proofing. This is using a sealant or caulking to fill the gaps in the floorboards of the house. It is also needed in area between the skirting boards and your floors.

One other way is putting an insulating layer under your carpet floor covering. You can use fiberboard underlay or polyfoam boards.

If you have access that will allow you to get into the crawlspace below the floorboards, it is easy enough. If it’s not possible, you need to take up the floorboards and need netting or wooden battens to hold the glass or mineral wool in place beneath the floorboards.

Choices

Fiberglass insulation is sold in rolls and batts. Both are available with or with the Kraft paper facing. Rolls are easy top carry and they can be cut easily to your desired length and size. Both are good in covering large areas.

The batts are in pre-cut lengths for faster installation. Every package has more square feet those in rolls, just perfect for framed cavities.

The faced insulation that uses Kraft paper which will act as a vapor barrier will be able to control the moisture transmission between the walls and the floors. The unfaced insulation without the vapor barriers can be used over existing insulation in attics where there is no need to control the moisture.

With the high-performance all-purpose insulation, you also will get the benefits of improved air quality, fire resistance, sound proofing, and great thermal performance.

Installation

Getting the right size (length and width) of your insulation would need some measurements on the floor joists that you will insulate. You also would have to measure the width between the floor joists so you will have the correct insulation joists.

There is a need to have a continuous contact with the subfloor about the insulation. If there are gaps between the floors and the insulation, the air movements will reduce the effectiveness of the insulation. (Always consult an expert, just to be sure, when you are doing it yourself.)


Floor insulation certainly saves money in the long run as it will cut down on your energy bills. However, this is not the only form of insulation you should do for your home.
