The insulation and its properties.

• Thermal insulation

  Real insulation performance in the assembly — from classic residential to net-zero buildings.

  The thermal insulation of an assembly is often described via thermal conductivity. What truly matters, however, is the real performance once installed. Alongside pure heat conduction, convection within the insulation layer plays a central role. Even minor leaks or voids can cause air movement that significantly reduces effective insulation performance.

  isofloc is blown into the assembly as a loose-fill insulation, completely and at a defined density. This creates a homogeneous, convection-free insulation layer in which heat transfer occurs almost exclusively through heat conduction. Uninsulated areas and uncontrolled air flows are minimised.

  The snug-fit, joint-free application ensures consistently high insulation quality — regardless of assembly geometry, construction or climatic conditions.

  Thanks to its outstanding thermal insulation properties, isofloc is suitable for a wide range of applications and building standards — from classic residential to net-zero buildings.

• Thermal storage capacity

  Summer heat protection through thermal inertia.

  Summer heat protection is an unsteady process governed by a material's thermal diffusivity. isofloc has a high volumetric heat storage capacity and can absorb and release heat with a time delay. This creates a phase shift in heat ingress, reducing temperature peaks and shifting them into the night. In timber construction in particular, the insulation thus takes on the additional function of thermal storage.

  isofloc thus enables passive summer heat protection without additional technology.

• Moisture behaviour

  Moisture regulation as a central element of building physics.

  Moisture is an integral part of every construction and must be understood as a dynamic process. Transport occurs via diffusion, convection and capillary processes, with convection being the dominant damage mechanism. isofloc actively manages moisture. As a hygroscopic insulant, cellulose has marked sorption properties, allowing it to absorb and temporarily store moisture.

  In addition, the structure allows moisture to be redistributed within the construction, reducing local moisture peaks.

  Under real conditions, evaporation often exceeds condensation, provided the construction is able to dry out.

  isofloc thus ensures a hygrothermally stable and fault-tolerant construction.

• Airtightness

  Controlling airflow as the basis of well-functioning constructions.

  Airtightness is central to every building envelope. Convective moisture transport is many times greater than diffusion and is the principal cause of damage.

  isofloc does not replace the airtightness layer but improves the system's behaviour through complete cavity filling and high flow resistance.

  This reduces internal air movement and stabilises the construction's performance.

  isofloc thus increases robustness against execution errors and contributes to a durable, secure building envelope.

• Fire protection

  System behaviour with active extension.

  In a fire, isofloc behaves typically of cellulose: pyrolysis and charring form a protective layer.

  This layer reduces heat ingress and prevents oxygen supply. Unlike other materials, no voids, no dripping and no uncontrolled failure occur.

  With easyfloc Protect, the insulation itself becomes an active part of fire protection, achieving proven fire-protection effectiveness in the assembly.

  isofloc thus evolves into a functional fire-protection solution in timber construction.

• Acoustic insulation

  Absorption as the key in lightweight construction.

  isofloc acts as a porous absorber, reducing sound energy by converting it into heat.

  The complete and uniform application creates a uniform acoustic effect throughout the cavity, avoiding resonances.

  isofloc thus contributes substantially to acoustic quality in timber-frame constructions.

• Sustainability

  Material cycle and indoor air quality.

  isofloc is based on recycled cellulose fibres and uses an existing material cycle. Energy input in production is low.

  Studies show that no significant indoor fibre load arises and the application is harmless to health.

  isofloc thus combines ecological responsibility with technical performance.

• Net zero / CO₂

  Insulation as an active part of the climate strategy.

  isofloc binds CO₂ throughout the building's service life and acts as a carbon sink.

  Thanks to its biogenic origin, the insulation achieves up to around 80 % accountability, making a substantial contribution to the CO₂ balance.

  isofloc thus becomes an active building block for climate-effective construction.
