How to Lower Heating and Cooling Costs

40% of the heat in your home comes through the structure’s thermal bridges. You will find thermal bridges in places that allow in more heat than surrounding areas.

An uninsulated floor will radiate more heat than the insulated walls. In this context, the floor acts as a thermal bridge. Furthermore, you may not know about many other thermal bridges.

Your windows are the most obvious example of a thermal bridge, but other places can allow in heat. Therefore, roller shutters can cut the amount of light that gets into your home and thus reduce the amount of heat that filters through your windows. They also improve the security of your home. You should investigate intentional punctures to decrease your home’s temperature and heating costs.

Intentional Punctures

An intentional puncture is any place in your home that has a purposefully created hole on the outside. Intentional punctures are things such as water pipes, sewage lines, air conditioning units, and electrical wiring. By design, an intentional puncture should be sealed very close to the pipe or the wire that comes into the house. However, this is not always the case.

Time, weather, or sloppy work often makes the intentional puncture much larger and allows hot air from the outside to filter into your home’s interior. Therefore, you must seal up the intentional puncture to reduce the amount of thermal bridging. If you prefer a more thorough approach, you can use caulk, plumber’s putty, or another type of material. If you are not worried about aesthetics, a foaming sealant from a can usually suffices.


Windows are not intentional punctured, but they tend to have a few of the same problems. For example, if they are not properly set into the wall, they can gape and create drafts. Also, depending on the material of the window, the frame may no longer fit easily into the wall due to years of swelling and contracting.

Therefore, you need to improve the seal. You should consider implementing an effective solution, such as replacing the window, sealing the cracks, or purchasing shutters.

Shutters help for several reasons. They shade you from the light, and you can decide how much sun you want to block. A significant amount of the heat in your home comes from the light that leaks into your house. They also improve the security of your home.

The Floor

If your floor is not insulated, it most likely allows heat to seep into the home. During the summer, the ground takes a while to heat up. However, once it does, it maintains the warmth throughout the night.

Ground temperature is much more constant than air temperature. So, even if heat is no longer passing through your walls and windows when the temperature drops at night, it is passing through your floor.

As a solution, you can have your floor insulated, clear out your crawl space so the transfer of heat is not as easily facilitated, or you can install carpet. Rugs will also suffice. They are a pale substitute for actual insulation, but they can effectively reduce the heat.
