ProRend External Insulation Finishing System (EIFS) is a complete render solution. Available in two primary construction methods: Adhesive (with secondary mechanical fixings; suitable for uneven substrates and curved walls using mineral wool lamella), and U-PVC rail (which mechanically holds the edges of the insulation; suitable for uneven substrates).

Features and benefits:

  • Building Regulations Approved Documents B ('Fire Safety') and L ('Conservation of Fuel and Power')-compliant.
  • Watertight facade.
  • Breathable render system.
  • Low maintenance.
  • CFC/ HCFC-free insulation.
  • Zero Ozone Depletion Potential (ODP) and zero Global Warming Potential (GWP).
  • U-value can be as low as 0.10 W/m²K (using 250 mm EPS).

ProRend EIFS (adhesive) system includes:

  • ProRend Lite Basecoat.
  • ProRend EIFS Platinum EPS.
  • ProRend Lite Basecoat.
  • ProMesh Grade 3.
  • ProRend Lite Basecoat.
  • ProRend Colourtex (with primer) or ProRend Mineraltex.


  • Residential.
  • Commercial.
  • Renovation.
  • New build.

Suitable substrates:

  • Concrete.
  • Masonry.
  • Timber frame.
  • Steel frame.
  • Existing render.

Reflective values:

Where intense or dark colours are used, the surface will be subject to increased thermal stress from (for example) solar radiation. Significant fluctuations in temperature, as experienced in temperate weather climates, will cause premature degradation in the finished surface. The dissipation of this heat will vary, dependent upon the background, and accordingly 'reflective values' should be adhered to as follows:

  • ProRend EIFS insulation systems: >20% clarity.

Standard product features


- Expanded polystyrene (EPS):

  • Size: 1000 x 500 mm.
  • Manufactured to BS EN 13163:2001.
  • Fire classification: E (contains fire-retarding additive).
  • Water vapour permeability to BS EN ISO 10456, Table 4: 60/60.
  • Nominal density: 14–16 kg/m³ (70 white and platinum). 30–32 kg/m³ (200 white).

- Mineral wool:

  • Fire classification: A1.
  • Water vapour permeability to BS EN ISO 10456, Table 4: 1/1.
  • Nominal density: 126–140 kg/m³.

Mineral Wool can be used as a sole insulant in ProRend EIFS projects or to serve as a fire barrier in EPS-type application. Mineral Wool fire barriers are typically used as follows:

  • ProRend EIFS adhesive EPS applications using mineral wool lamella.
  • ProRend EIFS rail EPS applications using mineral wool rail slab.
