Understanding indoor climate during construction

Indoor climate during construction

Indoor climate during the construction phase: prevent condensation, mold, and delays


During the construction phase, the indoor climate is constantly changing due to weather influences, construction moisture, and finishing activities. These fluctuations have a major impact on drying processes, material behavior, and the moment when finishing work can be carried out safely. Inscio monitors the indoor climate in real time, so that construction teams know exactly when there is a risk of condensation, mold, or drying delays.


Why indoor climate is so important during construction

The indoor climate largely determines whether materials dry on time, whether structures remain stable, and whether finishing work can begin safely. In practice, however, the indoor climate during the construction phase is:

  • unpredictable due to weather conditions
  • varying due to temporary openings, ventilation, and construction activities
  • full of building moisture after plastering, painting, flooring, and wet processes
  • temperature-sensitive, which affects dew point and condensation

These changes often lead to:

  • delayed drying of floors, CLT, biobased insulation, and roof construction
  • condensation on cold surfaces or in structures
  • risk of mold growth
  • problems with finishing (gluing, leveling, installing finishes)
  • failure costs due to premature continuation of construction

That's why understanding indoor climate isn't a luxury — it's essential risk management.

What does Inscio measure?

What Inscio measures during the construction phase

Temperature

  • understanding heating and cooling
  • detection of cold zones where condensation quickly forms

Relative humidity (RH)

  • construction moisture after wet processes
  • effect of ventilation and heating
  • recognition of areas that do not dry sufficiently

Dew point

  • real-time calculation of condensation risk
  • alert for temperature-RH combinations that become critical
Typical risks that Inscio sees in projects
  • Condensation behind insulation or on CLT/roof sections
  • Cement screeds remaining wet despite apparently good ventilation
  • Mold growth in biobased insulation or facade components
  • Premature finishing, causing materials to trap construction moisture
  • Highly variable RV, causing materials to swell or tear
  • Stagnant drying during cold periods

These risks arise unnoticed — and without monitoring, they only become apparent once damage has already occurred.

How Inscio helps you during construction

Temperature, RH, and dew point are continuously measured and translated into risks.

The software immediately reports when moisture levels rise or drying stops.

You can see exactly when the construction moisture has disappeared and the finishing phase can safely begin.

No more discussions about planning too early or too late — the data speaks for itself.

Understanding what really helps, rather than what just seems logical.

Our customers tell their stories

"Thanks to Inscio's sensors, we can clearly see how much moisture the wood is exposed to during the construction period."

Taco Valstar – ERA Contour

 Until last fall, we informed clients and partners about expected roof behavior based on practical experience. Now we provide objective measurement data.

"We believe that things can and must be done differently."

Imagine this: you take your car to the garage for maintenance. The mechanic stares at the shiny paintwork with a concerned look, runs his hands over the surface, and takes some photos. Then he comes back excitedly and concludes that the engine is broken and needs to be replaced.  

That sounds absurd, doesn't it? And yet that is roughly what happens during real estate inspections. We believe that things can and must be done differently.
