Thermal Imaging Inspections
Thermal Imaging Inspections for Detecting Building and Equipment Faults
Identify faults before they become failures.
APT Sound Testing provides professional thermal imaging inspections to detect heat loss, electrical faults, moisture intrusion, and equipment issues in buildings and industrial systems. Using advanced infrared technology, our surveys help contractors, developers, and maintenance teams save time, reduce costs, and prevent safety hazards.
What Is Thermal Imaging?
Thermal imaging detects heat variations emitted by surfaces and materials. Using high-resolution infrared cameras, we capture detailed images that reveal hot and cold areas, identifying potential faults or inefficiencies.
When combined with blower door testing, thermal imaging becomes a powerful diagnostic tool for analysing building envelopes, pinpointing air leaks, insulation gaps, and structural weaknesses that are invisible to the naked eye.
Industries That Benefit from Thermal Imaging
One of the greatest advantages of thermal imaging is that it allows non-intrusive inspection. There’s no need to shut down equipment or interrupt operations.
Our certified thermographers can inspect systems safely from a distance, capturing accurate data without putting personnel or assets at risk. This makes thermal imaging invaluable across many industries, including:
- Construction & Property Development
- Manufacturing & Industrial Maintenance
- Facilities Management (FM)
- Utilities & Energy
- Residential Building Inspections
Thermal Imaging for Building Inspections
Thermal imaging is a proven method for detecting issues in a building’s walls, roofs, floors, and insulation systems. It can identify:
- Missing or damaged insulation
- Dampness and water leaks
- Thermal bridging and cold spots
It’s also worth noting that undertaking a thermal imaging survey can earn additional BREEAM credits for sustainable building performance.
Because moisture-laden materials are typically cooler than dry ones, our cameras can reveal hidden leaks and damp areas that traditional visual inspections might miss—saving you time, cost, and unnecessary disruption (e.g. scaffolding for roof access).
Thermal Imaging for Industrial Maintenance
For manufacturers and facility operators, unplanned downtime can be costly. Thermal imaging enables predictive maintenance and asset management without taking critical systems offline.
When integrated into a Condition-Based Maintenance (CBM) program, thermal imaging helps detect overheating electrical, mechanical, and process components before failure occurs. This reduces:
- Equipment downtime
- Repair and maintenance costs
- Safety risks and business interruptions
Thermal Imaging for Electrical Systems
Electrical systems, from main incomers and transformers to circuit breakers and distribution boards, are critical infrastructure.
Thermal imaging allows engineers to identify hotspots and overloaded circuits early, preventing system failures and maintaining consistent service delivery. Inspections can be performed safely and quickly without direct contact with live components.
Thermal Imaging for Home Inspections
Homebuyers and inspectors can use thermal imaging to detect hidden defects such as:
- Water leaks and dampness
- Missing insulation
- Air leakage and cold bridging
Our thermal surveys provide valuable insights, helping buyers make informed decisions and ensuring their investment is sound.
Air Leakage Detection with Thermal Imaging
When used with a blower door fan, thermal imaging can accurately detect air leaks in the building envelope. This allows for targeted remedial works to improve airtightness, reducing drafts and energy usage by up to 20% while enhancing indoor comfort and sustainability.
Locating Leaks in Underfloor Heating Systems
Thermal imaging is the fastest and least invasive way to identify leaks in underfloor heating systems. Instead of removing large sections of flooring, our thermographers can pinpoint the exact location of the issue, often allowing a single tile to be lifted and repaired, saving significant cost and disruption.
