Thermofloc VSD Membrane is a vapour control layer with Variable Surface Diffusion technology. This high-performance product is designed to provide superior moisture control and air tightness, while also allowing for variable rates of diffusion depending on the specific requirements of your building project.

The Variable Surface Diffusion technology built into these membranes allows them able to adapt to the specific moisture and air flow conditions of your building project. This means that it can provide a high level of resistance to moisture and air penetration in areas where it is needed most, while also allowing for controlled levels of moisture and air movement in areas where ventilation is required.

In addition to its superior performance, Thermofloc Vapour Control Layer is also environmentally friendly, with a low environmental impact and no harmful chemicals or emissions. It is also highly cost-effective, providing a cost-effective solution to moisture control and air tightness that is suitable for use in a wide range of building projects.

THERMOFLOC VSD Membrane is installed by stapling or glueing it to the supporting structure. The lining must be installed with the printed side facing inwards towards the room, i.e. with the fibrous side facing the thermal insulation.

Key Features:

  • Vapour Control Layer with Variable Surface Diffusion technology
  • Provides superior moisture control and air tightness
  • Allows for variable rates of diffusion depending on building requirements
  • High-quality, durable materials
  • Environmentally friendly with low environmental impact
  • Cost-effective solution for moisture control and air tightness.

Applications:
