Service · Thermographic surveys
Thermographic surveys, interpreted by façade engineers.
A thermal image shows where heat is escaping. Knowing why takes an understanding of how the wall, roof or window is built. We combine thermal imaging with façade expertise to turn images into answers.
What thermal imaging can find
- Missing, slumped or poorly fitted insulation.
- Thermal bridging at junctions, frames, balconies and structural connections.
- Air leakage around windows, doors, curtain walling and service penetrations.
- Damp and water ingress in walls and roofs.
- Defects in flat roofs, such as wet insulation beneath the covering.
When to use it
- To investigate cold spots, condensation, mould or high energy bills.
- On new buildings, to check the envelope was built as designed before defects periods end.
- Before or after refurbishment or recladding, to check thermal performance.
- As a quick, non-intrusive first step in a wider defect investigation.
Getting reliable results
Thermography depends on conditions. External surveys need a good temperature difference between inside and outside, dry weather and no direct sun on the surfaces being surveyed, which usually means the colder months and early mornings or evenings. We plan surveys around these conditions and follow the approach in BS EN 13187 for thermal imaging of building envelopes.
Most importantly, every image is interpreted by someone who knows how the façade is built. A warm patch might be missing insulation, a thermal bridge designed into the detail, or a reflection. Where the images point to a defect, we can confirm it with targeted intrusive investigations.
What you receive
- Annotated thermal and visual images, located on elevations or plans.
- A clear explanation of each finding and its likely cause.
- Practical recommendations, and next steps where further investigation is needed.
Frequently asked questions
When is the best time for a thermographic survey?
Usually in the colder months, early in the morning or in the evening, when there is a good temperature difference between inside and outside, the weather is dry and the surfaces are not in direct sun.
Is a thermographic survey intrusive?
No. Thermal imaging is non-intrusive. Where it points to a defect, targeted opening-up can confirm what is happening behind the surface.
Can thermal imaging find leaks?
It can often show damp and water ingress in walls and roofs, and wet insulation beneath flat roof coverings, which helps target further investigation.
Do you survey internally and externally?
Yes. Depending on what you need to find, we survey from outside, inside or both.
