A thermal camera is the most honest “exam” a house can take. It does not care about beautiful finishes and does not believe phrases like “our walls are warm.” It shows where the house is actually losing heat: through walls, corners, lintels, junctions, and joints.
And the good news is that a facade can be built in a way that makes an energy audit show not only beauty, but real performance.
What a Thermal Camera Shows and Why It Matters
A thermal camera usually reveals:
“hot” spots on walls (heat leakage)
cold zones inside (thermal bridges)
problematic corners and joints
areas where insulation was installed unevenly
places where air moves through gaps and junctions
And in most cases, the biggest losses are not “across the whole wall,” but exactly in the details: corners, reveals, board joints, plinth areas, and cornices.
The “Before/After” Case: What It Usually Looks Like
Before
On a thermal camera, the facade often shows:
bright spots at corners and around window perimeters
“stripes” where boards or joints meet
strong heat loss in the plinth area
temperature differences across the same wall
This means heat is escaping outside, while cold zones remain inside the wall, where condensation may later appear.
After
After a proper facade solution is installed, the thermal image usually shows:
a more even temperature pattern across the wall
fewer bright “hot” spots
reduced contrast at corners and around windows
a more stable surface temperature
In other words, the house loses less heat and becomes more comfortable.
Why Cladding Alone Does Not Solve Heat Loss
It is important to be honest: tile is not insulation.
A thermal image improves not because a textured finish was added on top, but because the facade becomes a complete system:
insulation reduces heat loss
reinforcement and proper detailing remove weak points
the outer layer protects the system and helps keep it working properly over time
That is why the key step is Facade Insulation, which moves the dew point outward, reduces heat loss, and makes wall temperatures more stable.
Where a Thermal Camera Most Often Finds Problems When a Facade Is Done “In Parts”
If insulation, detailing, and finishing were done by different crews, an energy audit most often reveals:
corners without proper reinforcement
junctions around windows and doors
insulation board joints
the transition to the plinth
cornices and protruding elements
This is not a “thermal camera mistake” — it is real building physics: in those places the layer is thinner, the detail is weaker, or air leakage is present.
How to Make the Thermal Camera “Before/After” Difference Truly Visible
Insulate the facade evenly, without weak spots
Carefully design all details: corners, reveals, junctions, and plinth areas
Apply the reinforcing layer as one continuous shell
Protect the system with the right finish so it does not degrade from water and sun exposure
Where Flexible Tile Comes Into the Picture
The finish layer does not “make the house warm,” but it does make the insulation system more durable and protected. If the outer layer is weak, the system loses its appearance faster, develops microcracks, and starts allowing moisture into vulnerable areas.
That is why in projects where a clean facade and system stability matter, many choose KORDEKO Flexible Tile (PletaFlex) as a finish over insulation: it helps create a practical facade and preserve its appearance without constant repairs.
Conclusion
A thermal camera shows the truth: where the house loses heat and which details were done incorrectly.
If the facade is assembled as a system — insulation, reinforcement, proper junctions, and a high-quality finish — then the “before/after” energy audit becomes truly visible: less heat loss, more even wall temperatures, and greater comfort inside.
