Terraco EIFS Perma System


Terraco EIFS (External Insulation Finishing System), also known as an external thermal insulation composite system has been developed to promote a comfortable indoor climate whilst substantially reducing the need for heating and/or cooling.

The Perma system utilizes MW (mineral wool) insulation boards which are fixed to the substrate using a combination of Styrofix adhesive and mechanical fasteners. The board is then strengthened with a range of quality profiles and Styrobond DP is applied and reinforced with a layer of glass fibre mesh. This creates a surface which is then primed and decorated using one or more decorative, high performance finishing coats. The system is particularly effective in cold and damp climates.

Features/ Benefits:

  • Substantially reduces cost of heating and cooling.
  • Eliminates condensation on walls and ceilings.
  • Enhanced soundproofing is achieved.
  • Excellent impact resistance.

Standard product features

Insulation board thermal conductivity (K-value):

0.040 W/mK.

Insulation adhesive:

Styrofix adhesive is easy to use by just adding water, improving on-site quality control. It shows excellent adhesion between substrate and EPS (expanded polystyrene), XPS (extruded polystyrene) and MW (mineral wool) insulation boards.

Reinforcement adhesive:

Styrobond DP basecoat and adhesive is easy to use by just adding water, improving on-site quality control. It shows excellent adhesion between substrate and EPS (expanded polystyrene) when used as an adhesive. It also provides an excellent basecoat for embedding glass fibre mesh on top of which EIFS finishing coat is applied.

Beads and trims:

  • Drip nose bead.
  • Groove bead.
  • PVC corner bead with mesh.
  • Starter base profile.
  • Window reveal bead.

Movement joints:

Movement bead.

Third party certifications

  • European Technical Approval: Certificate: 09/0384
