What is a Thermal Survey and Why Should I Have One?


Welcome to Eco Warm Walls! In this article, we will explore the concept of a thermal survey and why it is beneficial for homeowners. A thermal survey is a valuable tool that helps assess the thermal performance of your home, identify areas of heat loss, and determine the effectiveness of insulation. By understanding the importance of a thermal survey and its role in optimizing energy efficiency, you can make informed decisions about improving your home’s insulation. Let’s delve into the details and discover why a thermal survey should be on your priority list.

Understanding Thermal Surveys

a. What is a Thermal Survey?
A thermal survey, also known as a thermal imaging inspection, utilizes advanced infrared technology to capture thermal images of your home’s surfaces. These images reveal variations in surface temperatures, highlighting areas of heat loss and potential insulation deficiencies.
b. How is a Thermal Survey Conducted?
Trained professionals use specialized thermal imaging cameras, such as FLIR cameras, to capture the thermal data of your home. These cameras detect infrared radiation and convert it into a visual representation, enabling the identification of thermal anomalies.

The Benefits of a Thermal Survey

a. Detecting Heat Loss Areas:
A thermal survey allows you to identify areas where heat is escaping from your home. This includes poorly insulated walls, gaps around windows and doors, and other thermal weak points that contribute to energy inefficiency.
b. Assessing Insulation Performance:
By analyzing the thermal images, a thermal survey helps evaluate the effectiveness of your current insulation. It can determine if there are any gaps, voids, or areas where insulation has degraded, compromising its thermal performance.
c. Pinpointing Energy Loss and Cost Savings Opportunities:
The insights gained from a thermal survey enable you to prioritize energy-saving improvements. By addressing the identified heat loss areas, you can significantly reduce your energy consumption, leading to lower utility bills and long-term cost savings.

The Role of Thermal Surveys in Hydrophobic Coating Evaluation

a. Pre-Coating Assessment:
Before applying hydrophobic coatings, a thermal survey is conducted to establish a baseline of your home’s thermal performance. This provides crucial data for comparing and quantifying the impact of the coatings on energy efficiency.
b. Post-Coating Evaluation:
Following the application of hydrophobic coatings, a second thermal survey is performed to assess the improvements in thermal performance. By comparing the pre- and post-coating thermal images, the efficacy of the coatings can be objectively measured and validated.

The Importance of Lab Testing and Certification

a. Reliable Results and Peace of Mind:
Thermal surveying techniques, including FLIR photography, have undergone rigorous lab testing to ensure accuracy and reliability. Certified professionals employ standardized procedures to provide accurate thermal data, giving you confidence in the results.
b. Proven Field Performance:
Thermal surveying techniques have been extensively utilized in the field to assess the impact of hydrophobic coatings on energy efficiency. Real-life case studies and data reinforce the efficacy of these coatings in reducing heat loss and improving insulation.


A thermal survey is a valuable tool for homeowners seeking to maximize energy efficiency and improve insulation performance. By detecting heat loss areas and assessing insulation effectiveness, a thermal survey helps identify opportunities for cost savings and increased comfort. In the context of hydrophobic coatings, thermal surveys play a crucial role in evaluating their impact and validating their efficacy. At Eco Warm Walls, we believe in providing reliable and certified thermal surveying services to help you make informed decisions about improving your home’s energy efficiency.
