Thermal Bridging: What is it and How to Avoid it

 

Winter is coming. With that, it is going to become cold and uncomfortable outside. The last thing you want is to be cold and uncomfortable in your home. However, if you do not have proper insulation in your home, you can experience a significant amount of heat loss. This heat loss may be caused by something called thermal bridging, heat, or cold bridging. Heat bridging can occur in many areas of your home, particularly doors, windows, your floors, walls, and any openings in your walls. So, what is thermal bridging and how can you avoid this heat loss?


What is Thermal Bridging?
Thermal bridging has to do with heat transference through conduction. When the temperature is different on either side of a building material, inside and outside of your home, the heat will follow the path of least resistance. The heat in your home will be trying to escape your home and get to the outside. The heat will flow through the material to the lowest thermal resistance – the non-insulated wooden studs. These heat bridges are caused because the framing materials of your home conduct more heat than insulating your home. The R-value of your insulation might be high, but your framing materials might be bumping that rating down, due to its conductivity.
 
Thermal bridging is not only responsible for energy loss, but it can cause mold as this bridge causes the potential for condensation. If this is not dealt with, the mold can turn into a damp rot. 
How to Avoid Thermal Bridging  
The heat bridge can be broken, and added to any home, new or old. Any home can increase its efficiency by adding a layer of continuous exterior insulation. The exterior insulation wrap will stop the heat loss and heat bridging by insulating the wooden studs.
