Biobased building materials are sensitive to moisture

Biobased during construction

Biobased materials during the construction phase: control over moisture, drying, and quality

Biobased insulation and biobased building materials result in healthy, circular, and high-quality buildings—but they are particularly sensitive to moisture during the construction phase. Inscio continuously monitors moisture behavior, so construction teams know exactly when there is a risk of mold, degradation, or reduced insulation value. This preserves the quality of the biobased material while allowing construction to continue predictably.

 

Why biobased materials are vulnerable during the construction phase

Biobased materials are hygroscopic: they naturally absorb and release moisture. This makes them durable and breathable — but during the construction phase, this poses certain risks:

  • Moisture absorption due to rain or high RH
  • Slow drying when materials are sealed
  • Susceptibility to mold growth at prolonged high moisture levels
  • Risk of microbial growth in poorly controlled indoor climate
  • Reduced insulation value due to moisture in fiber structures
  • Change in shape or density (settling or swelling)

This behavior is not visible on the outside and can lead to quality problems after completion — unless it is continuously monitored.

What does Inscio measure?

What Inscio measures in biobased materials during the construction phase

Moisture content in biobased insulation

  • recognition of areas that retain moisture
  • understanding of drying behavior after rain exposure or installation

Temperature and relative humidity

  • direct influence on mold growth
  • important factor for drying and moisture transport
  • detection of dew point conditions at connection details
Typical risks associated with biobased materials

Projects show that the same problems keep recurring:

  • Biobased insulation that is sealed too early, causing moisture to become trapped
  • Rainwater containment for facade and roof installation
  • Mold growth due to prolonged high humidity levels
  • Moisture accumulation around thermal bridges
  • Loss of insulation performance due to wet fibers
  • Delayed drying due to low outside temperatures or poor ventilation
  • Microbial activity in warm, humid indoor environments

With real-time monitoring, these risks become visible as soon as they arise — not when the damage is already visible.

How Inscio helps you during construction

Measure what happens on and inside biobased layers.

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

Substructure precisely when you have safe conditions to close, finish, or continue building.

Data shows whether temporary films, membranes, and covers perform adequately

Trends show when biobased materials are at risk.

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.

Laurens van Wylick – Isomix insulating mortars

"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.
