ISOMAT THERMOSYSTEM WOOL is a bonding system of multiple layers, consisting of:

  • Thermal insulation boards of mineral wool.
  • Supplementary components (aluminium holding rail with embedded water drip, fiberglass mesh, corner profile with mesh etc.).
  • Special, high-quality mortar used as an adhesive both for bonding the thermal insulation boards and creating the base coat before rendering.
  • Silicone or silicone-silicate, water-repellent, vapor-permeable, pasty renders.

Certified according to ETAG 004 : ETA 16/0626

ISOMAT THERMOSYSTEM WOOL is the ideal solution for constructions with high requirements in fire protection, as mineral wool is highly fire-resistant. Being vapor-permeable, allows construction breathability, as well as sound insulating. Constitutes an excellent solution for renovating old constructions, thanks to the colored, high-quality renders MARMOCRYL SILICONE-SILICATE of ISOMAT, which are available in a wide range of colors through the ISOMAT COLOR SYSTEM color chart.

  1. Bonding of thermal insulation boards with ISOMAT AK-T35
  2. Thermal insulation boards of mineral wool mechanically fixed with ISOMAT collar head anchors
  3. Reinforced layer (base coat) of ISOMAT AK-T65 with THERMOSYSTEM RF fiberglass mesh (149 g/m² or 161 g/m²)
  4. Priming with SILICONE-PRIMER and rendering with MARMOCRYL SILICONE-SILICATE
