Thermal Imaging Surveys Explained
When it comes to maintaining the health and efficiency of your building, thermal imaging surveys are an invaluable tool. These surveys utilise infrared technology to detect temperature variations, revealing hidden issues that are invisible to the naked eye. From identifying energy losses to spotting water leaks and structural defects, thermal imaging surveys provide a comprehensive diagnostic solution.

Here at APT Sound Testing we have over 15 years of experience carrying out premium building thermographic surveys throughout England and Wales in support of industrial and commercial applications, our thermal imaging reports contain the required information to satisfy Construction and Insurance Companies, Facility Managers, Building Control and BREEAM Assessors.
What is Thermal Imaging?
Thermal imaging, also known as thermography, is a technique that captures infrared radiation emitted by objects. Unlike visible light, infrared radiation is invisible to the human eye but can be detected by thermal cameras. These cameras convert infrared radiation into an image that displays temperature variations, with different colours representing different temperatures. This allows for the identification of thermal anomalies that could indicate potential problems within a building, such as excess Heat Loss due to damaged insulation, moisture Intrusion due to water leaks, electrical Faults due to overheating electrical components and faulty wiring and Structural Defects due to compromised structural integrity.

Our thermal imaging surveys to commercial buildings, can provide extremely useful information about the thermal performance of the building envelope at minimal cost. We are the first port of call for many surveyors, if they need a thermal imaging defects survey.
An infrared survey can be undertaken to establish more than just heat loss; it can also be utilised for:
>>> Building energy efficiency – a heat loss thermal survey is essential as it identified where the biggest energy cost-savings can be made.
>>> Damp walls and ceilings and floors – water ingress, sources of dampness, leaks in flat roofs or roof lights.
>>> Water leaks – leaks in the buildings water systems.
>>> Thermal bridging areas – missing or ineffective insulation at door and window reveals, as well as door and window heads.
>>> Missing or damaged insulation – areas where poor workmanship leading to missing or damaged insulation causing cold spots within floors, walls and roofs.
>>> Air infiltration – cold draughts into the building through the building envelope that can excess draughts leading to an unpleasant environment for building occupants.
>>> Excess Air leakage paths – warm air escaping through the building envelope that wastes valuable energy or struggling to keep the building cool in summer.
BREEAM Thermal Imaging Surveys
Thermal imaging surveys have become a core component of BREEAM—the world’s leading environmental assessment and rating system for buildings. BREEAM establishes the benchmark for excellence in sustainable building design, construction, and operation. Both BREEAM New Construction and BREEAM Domestic Refurbishment programs acknowledge the importance of thermal imaging surveys, awarding credits for assessments conducted by a Level 2 certified thermographer.
For over a decade, APT Sound Testing has been providing professional BREEAM thermal imaging surveys to ensure insulation continuity in buildings. To meet the exacting standards of BREEAM, our infrared inspections are carried out by Level 3 certified thermographers, using state-of-the-art, high-resolution FLIR thermal imaging cameras to deliver precise and reliable results on every project.
