Thermal tracking is a problem that plagues homeowners, and the worst thing about the issue is that it's sometimes hard to detect. Not only are the signs of thermal tracking often mistaken for another issue, but some homeowners also have never heard of the problem, and therefore, don't even know the first sign to look for. If you want to protect your home, learn more about what thermal tracking is and how you can manage the problem.
Thermal Tracking
Thermal tracking, sometimes referred to as thermal bridging, is an issue that can target any home that uses a central heating system. When these systems power on, dust, dirt, and other particles naturally found inside a home become airborne and circulate through the air.
When thermal tracking is an issue, these particles often settle on the walls and form dark spots that look like soot or mold. This issue arises when there is a significant difference in temperature between the drywall and the studs that support the wall.
The temperature imbalance causes condensation to develop around the wall studs, which are typically cooler than the drywall. The problem with condensation is that it works as somewhat of a magnet that attracts the dust and dirt particles. If you notice these spots on your walls, thermal tracking is likely to blame
Correcting the Issue
In homes with thermal tracking issues, there are typically a couple of common issues that are taking place. One of the issues is a poorly maintained air filter, and the other is a lack of adequate insulation. The air filter inside your heating system is intended to trap the dust and dirt particles that circulate through the air.
However, when the filter is not cleaned or changed regularly, it cannot adequately capture the particles, and as a result, more of them end up in the air, and ultimately, settle on the wall. In terms of the insulation, the temperature difference between the studs that support your wall and the drywall should not be significant. If it is, it's an indication that your home does not have enough insulation.
A lack of insulation means that a large amount of cold air is settling on the backside of the drywall, while the warmed air from inside your home settles on the other side of the wall, which is the reason for the condensation. If you improve the insulation, you can eliminate the problem.
Speak with an HVAC contractor should you have any thermal tracking concerns.

While sitting in my living room on a hot summer day, I could feel the heat coming through the ceiling out of my attic and making the house warm up more than it should. I crawled up into the attic one evening to find out that the roof vents weren't working any longer because they were clogged with all sorts of debris. Did you know that when this happens, your home's temperature can rise to very uncomfortable levels? Did you know that your home could actually be damaged if the attic isn't well vented? This blog will show you all about attic ventilation.
