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

  • Thermal insulation boards of expanded polystyrene (EPS).
  • Supplementary components (aluminium holding rail with embedded water drip, fiberglass mesh, corner profile with mesh etc.).
  • Special fiber-reinforced mortar used as an adhesive for both bonding the thermal insulation boards and creating the base coat before rendering.
  • Acrylic, water-repellent, pasty renders.

Certified according to EAD 040083-00-040.

ISOMAT THERMOSYSTEM CLASSIC is the most cost-effective thermal insulation solution proposed by ISOMAT. Being vapor-permeable, allows construction breathability. Constitutes an excellent solution for renovating old constructions, thanks to MARMOCRYL colored, high-quality pasty renders 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
