We offer expert blower door testing services to help you make your building as energy-efficient as possible.
When planning a new construction project, it’s important to stay up-to-date with the latest building code requirements. One recent addition to these codes for the state of Florida is that all new construction projects must have blower door testing done on the structure. Blower door testing is a method that tests the level of uncontrolled air leakage in a building, and it is used to draw conclusions about the structure’s indoor air quality and energy efficiency. At Polk County Insulation, we understand that this process may be new to a lot of people, so in this article we will provide an overview of how it works and what to expect.
Blower door testing is named for its signature tool, the blower door, which is a large fan that is set up in one of the exterior doors of your home. In addition to the fan, a blower door is equipped with gauges that measure the air pressure inside your home. Our team at Polk County Insulation will install the blower door so that it completely fills up and seals your doorway. Once that is in place, we can begin the testing process: the fan pumps air out of your home, lowering the air pressure inside. This lower air pressure causes higher-pressure air from the outdoors to rush inside through any unsealed cracks.
After starting the blower door and creating the right air pressure conditions, the next step is to locate the unsealed gaps where air is leaking through. There two main tools that our technicians at Polk County Insulation use to detect such gaps. The first is a smoke pencil, which is a handheld device that creates jets of heatless smoke. This smoke is then blown along with the rest of the air, allowing us to see the invisible air currents at work in a space. Our second tool of choice is heat-sensitive cameras. These devices capture data that allows us to observe even tiny differences in the air temperature, which in turn allows us to identify places where air is leaking into a building from outside. Using these tools, our team gathers information about the overall airtightness of a new building, as well as its airflow conditions. This data in turn allows us to draw conclusions about its energy efficiency and indoor air quality, both of which have code requirements that must be met.
While blower door testing is a requirement for new construction in the Davenport, Florida, area as it is in the rest of the state, there are plenty of people who choose to have it conducted on their existing homes or business facilities in order to assess their energy efficiency. If you want to make your property as efficient as possible, blower door testing can be a great information-gathering strategy to help you accomplish that goal.
