Quality Thermal Imaging Cameras & Building Surveys
When we undertake thermal imaging surveys, we only use the FLIR P6n thermal imaging cameras, as they are an excellent choice for BREEAM requirements, due to its high resolution, sensitivity, and advanced features. Here are some key specifications that make it suitable for our BREEAM thermal imaging surveys:
High Resolution
The FLIR P6n offers a high resolution of 640 × 480 pixels. This high resolution ensures detailed thermal images, allowing for accurate identification of temperature variations and potential issues in building structures. The higher the resolution the more detail we can provide to clients.

High Thermal Sensitivity (NETD)
The camera has a very thermal sensitivity (Noise Equivalent Temperature Difference, NETD) of less than 0.03°C. This high sensitivity allows the camera to detect even the smallest temperature differences, making it ideal for identifying insulation deficiencies, air leaks, and other subtle thermal anomalies that many other cameras simply miss.
Wide Temperature Range
The FLIR P6n can measure temperatures ranging from -40°C to 650°C. This wide temperature range makes it versatile for various applications, including detecting heat loss, moisture infiltration, and electrical malfunctions.
Wide Field of View (FOV)
The camera features a field of view (FOV) of 25° × 19°. This FOV is suitable for capturing comprehensive thermal images of building envelopes, ensuring thorough inspections during BREEAM thermal imaging surveys. This wide FOV captures more detail within a single image.

Additional Features
One of the most important features of the FLIR P6n is its MSX® image enhancement, which overlays thermal images with visual details for better clarity and context.
Another great feature is the built-in GPS for geotagging images, making it easier to document and reference specific locations during surveys.
These specifications make the FLIR P6n thermal imaging camera a powerful tool for conducting BREEAM thermal imaging surveys, ensuring accurate and reliable results that contribute to the overall sustainability and efficiency of buildings.
Saving money by investing in a thermal imaging survey
Investing in thermal imaging surveys ultimately translates into significant cost savings for businesses. By identifying potential failures before they occur, organisations can undertake preventative maintenance that is far less costly than emergency repairs. For example, the cost of replacing an overheated electrical component after a fire incident far exceeds the cost of conducting routine thermal imaging inspections to catch the issue early. Moreover, improved energy efficiency resulting from identifying HVAC and insulation issues can lead to substantial reductions in utility bills. For large buildings, these savings can accumulate to significant figures over time.
As such, thermal imaging surveys not only enhance safety but also provide a solid return on investment through preventative measures and efficiency improvements. That’s why Thermal Imaging has been embraced by BREEAM and Building Regulation Part L.
