Walls

Cellulose Insulation Technologies in Timber Construction

We distinguish several common application methods:

Wet Spray Application

Used mainly in North America and Finland

  • Applied directly on-site
  • Requires advanced installer training
  • Less material usage (35–40 kg/m³)
  • Declining market share due to rising labor costs
  • Not suitable for off-site prefabrication

Rotating Nozzle Injection

Common in Central and Western Europe

  • Most accessible and cost-effective method for quick wall insulation
  • Insulation is blown through a nozzle inserted into a predrilled hole in the wall
  • Uses more material than wet spray (55–60 kg/m³)
    But this results in better acoustic insulation, higher thermal mass, and improved fire protection
  • We offer accessories for wall injection produced by our German partner Geko-Maschinenbau.

Cellulose Insulation Technologies in Timber Construction

Let’s Work Together

We invite manufacturers of timber buildings to explore blown-in cellulose technology—a method that delivers significant savings in time and labor costs, while ensuring excellent structural insulation performance.

Industrial Lance Injection Technology

  • Also under development for high-efficiency applications

Blowing with Pressurized Plates – For Modular Homes

  • Designed for off-site modular construction in factory settings
  • Enables precise density control and even cavity fill
  • Still requires optimization for production speed in large-scale operations
