Thermographic surveys allow for the nondestructive investigation of areas suffering from heat loss or discomfort.
When at home or in the office, being the right temperature is incredibly important to comfort levels. Our body can detect the slightest temperature changes, with it only taking approximately 3°C difference between head and toe to feel a “draft”. This difference in temperature can be caused by many things, such as poor insulation in the floor or walls to cold bridging found in concrete slabs. Investigative thermography provides objective evidence for the causes of these issues, which is often used to resolve claims and disagreements.
iRed conducts investigative surveys throughout the year on both domestic and commercial properties, employing the latest in thermal imaging, heat flux sensor and TinyTag data logging technology to record a variety of factors such as humidity levels (for anticipating damp and mould), heat patterns and thermal comfort. Our detailed and comprehensive reports include an overview of thermal comfort levels, along with an analysis of the potential causes of any low values. Additionally, our reports are signed off by a UKTA approved Level 3 thermographer and adhere to the strictest standards.
Investigative thermography can also be used as a marketing tool, in which products and materials can be visibly tested to prove authenticity or provide comparison to a competitors product.
Frequently Asked Questions
Thermography (otherwise known as “Thermal Imaging”) is a specialist technique which uses infrared-sensitive cameras to inspect buildings, electrical equipment, rotating machinery and devices to detect faults or problematic areas, as part of routine maintenance or fault-finding. This non-invasive method allows the identification – both in terms of location and severity – of problems associated with heat loss.
Rather than using a CMOS or CCD detector which records different levels of a range of visible light colours, a thermal imaging camera uses a microbolometer array to accurately measure levels of infrared radiation across a scene. This temperature data is then processed to produce a thermal image (known as “thermogram”), which can then be very precisely quantified or measured.
It is recommended that certain conditions are met to ensure any outcomes within our reports are fully accurate and actionable. To ‘see’ heat loss (or gain) at least a 10°C temperature difference between the inside and outside must be achieved for a minimum of 24 hours prior to the survey if occupied, or 72 hours for a ‘dead’ building. If the building has no operational heating system, temporary direct heaters (such as space heaters) may be required. It’s because of this that surveys can often take place very early in the morning or late in the evening.

Upon completetion of a thermographic survey, clients will recieve a precise and detailed report featuring comments and advice from experienced and highly qualified thermographers. We only allow level 2 or above thermographers to produce our reports, ensuring your report is as comprehensive as possible. We’re then available to help, explain and troubleshoot your new thermal data with you as much as you need.
Absolutely! All of our thermographers are level 1/2/3 certified. We are also a CHAS accredited contractor, registered Constructionline supplier, UKTA approved to conduct BREEAM thermographic surveys, BINDT approved training centre and ISO 9001:2008 registered.

No, it’s totally harmless! Everything gives off infrared radiation, and thermal imaging cameras merely detect this existing radiation (rather than emit anything).
