Thermal Imaging Surveys

Our thermal surveys provide a non-destructive assessment of a buildings thermal performance. This allows us to measure heat loss, detect thermal bridging and assess insulation.

Find Heat Loss

Thermal imaging uses heat-sensitive cameras to detect differences in temperature. This is used to investigate areas of heat loss within buildings.

Missing Insulation

Thermal imaging can highlight areas of missing, damaged or inadequate insulation. This is often caused by design oversight, damage during construction or water ingress.

Identify Thermal Bridging

Thermal bridges – also known as a cold bridge or thermal bypass – are areas of significant structural heat transfer between the inside and outside of a building.

Assess Thermal Comfort

Infrared cameras can be used to locate the causes of thermal discomfort. This is by finding air leakage through cracks and unintentional openings in buildings.

Identify Water Ingress

We inspect walls, floors and roofs for leaks, water ingress and moisture. Using thermal imaging also enables us to assess the probability of damp and mould in buildings.

Dispute Resolution

Our surveys provide definitive evidence for dispute resolution. We’re also the preferred supplier for NHBC, and many builders, housing associations an homeowners nationwide.

Thermal imaging building surveys provide a non-destructive assessment of a buildings thermal performance. Using non-contact infrared cameras, we’re able to identify problems associated with heat loss. This includes missing or damaged insulation, air leakage and moisture ingress.

Our certified inspectors provide actionable and definitive evidence, tailored for your project. We also employ damp meters and remote data loggers for bespoke reporting. This enables us to create a wide range of customised reports, with data for every situation.

Insulation within a building may be compromised at several points during it’s life. To ensure suitable energy efficiency all year-round, we recommend regular thermal inspections. Our inspections assess insulation for these common issues:

Design Oversights

Oversights, or differing standards at the time of construction, may leave areas uninsulated. The repurposing of buildings are particularly vulnerable to design deficiencies. For example, the incorporation of a lean-to cattle shed into an extension. These oversights can be detected by thermal cameras, showing areas for immediate improvement.

Poor Construction

Builders may not always use the correct materials, according to the design. This can be due to forgetfulness, lack of skill or a desire to save on material costs. Thermal surveys can be used to check and audit questionable areas.

Damage During Construction

Unintended actions, such as falling mortar within a cavity, may damage insulating materials. Most commonly, discarded drink cans can often be found within the structure of a building. If left undetected, these can subsequently compress insulation.

Disturbance After Construction

Disturbance after construction can be caused by a variety of factors. For example, wildlife such as squirrels have been known to damage roof insulation. Additionally, unintended or careless disturbance can often happen during further building work. In these situations, an extension to a property can cause faults in existing areas.

Passive Damage to Materials

Some insulation types, particularly older materials, are vulnerable to damage from water ingress. These materials may also break down naturally over a long period of time. These defects in insulation cause thermal bridges, which are detectable using thermal imaging.

We have 5 requirements for a thermal imaging survey.

1. Heated Building

To ‘see’ heat loss (or gain) there must be a temperature difference of at least 10ºC between the inside and outside of a building. For occupied buildings, this temperature difference must be achieved 24 hours prior to the survey. For unoccupied buildings, this temperature difference must be achieved for 72 hours prior to the survey.

If the building has no operational heating system, temporary direct heaters (such as space heaters) may be required.

2. Dry Surfaces

Before a survey, building surfaces must be dry so that artifi cial cooling from moisture evaporation does not skew the results. For heavy building fabrics such as brick, it’s recommended that surfaces have been dry for at least 24 hours. For lightweight buildings, a minimum of 12 hours is recommended.

3. No Obstructions

The building fabric must be kept free from obstructions such as furniture and building materials. Any obstructions must be moved at least an hour before the start of a survey, in order for local temperature conditions to stabilise.

4. No Solar Radiation

Building surfaces must be free from solar radiation for a minimum of 2 hours prior to the start of the survey – longer if the building consists of a heavyweight fabric. This is to allow for the effect of external heat gain in the wall to dissipate.

Typically, surveys can be expected to start at 00:00 during summer and 20:00 during winter.

5. Low Wind Speed

Wind speed during a survey should not be greater than 5m/s (18kph). This is to stop the cooling effect from exceeding recognised compensation values.

Home Quality Mark Survey

Our inspectors are approved to deliver thermal surveys for the new Home Quality Mark. The mark, developed by BRE, has been designed for housing developments and new builds.

The Home Quality Mark (HQM) is a national standard for new homes. It uses a simple 5-star rating system to assess a home’s design, construction quality and running costs. This is calculated using impartial information from independent experts.

How does it work?

During a survey, our team will test the integrity of a building post-construction. This includes:

  • Assessing the continuity of insulation
  • Finding any possible thermal bridging
  • Detecting any air leakage pathways

Once a report has been generated, it’ll be passed to your Home Quality Mark assessor. The assessor will then submit it as part of your HQM application.
