Thermal bridging, also known as thermal tracking or “ghosting,” is the movement of heat across an object that is more conductive than the materials around it. It is one of the major sources of energy loss in homes and buildings that result in higher utility bills—it can account for heat loss of up to 30 percent in an airtight and insulated home.
Today, the siding and roof replacement pros of ReNew Home Designs take a closer look at thermal bridging and ways it can be prevented.
What Causes Thermal Bridging?
You know you have thermal bridging inside your home once you notice those unsightly dark stains on your walls and ceilings. These are common in environments that have a high concentration of particles like soot, fine dust, and other airborne debris. Smoking, drafts, and dirty vacuum filters are some of the factors that contribute to the accumulation of particles inside the home.
Thermal bridging occurs as a result of insufficient insulation. Condensation can develop when the wall studs feel colder than the drywall, which then attracts dust and soot particles and retains them. Over time, the stains become even more visible on the walls and ceilings, appearing in either consistent or erratic patterns. Unfortunately, these marks are already difficult to remove at this point.
How Can It Be Prevented?
For roofers and siding installers, one way to solve this problem is similar to how it is done on worn-out siding: scrape and repaint the affected wall or ceiling. This, however, doesn’t address the real cause of thermal bridging. Preventing this issue starts with an assessment of your home’s indoor air quality and humidity.
The presence of soot and dust particles in your home is a sign of poor indoor air quality. To make it healthier to breathe, you must make sure that dirty HVAC filters are replaced and your home is well-ventilated. Also, indoor humidity levels must be controlled to limit condensation that contributes to thermal bridging. By addressing insulation issues, particularly the exterior walls, you can help give your home’s energy efficiency a boost.
