KLEIB External Wall Insulation System

The KLEIB EWI System, certified under NSAI Agrément 19/0413, is a high-performance façade insulation solution for masonry and concrete buildings up to six storeys. It uses EPS or graphite EPS insulation, a reinforced basecoat with mesh, and durable acrylic or silicone renders to deliver long-term energy efficiency and weather protection. Installed by NSAI-approved contractors, the system achieves U-values as low as 0.21 W/m²K, with a design life over 30 years and full compliance with Irish Building Regulations.

Use

KLEIB External Insulation Systems are designed for external insulation of existing masonry or concrete dwellings.

  • Suitable for buildings up to 6 storeys (18m) in height.

  • Ideal for energy-efficient retrofitting and thermal performance improvement.

 
System Components

  • Insulation: Expanded Polystyrene (EPS) boards — white (λ=0.039 W/mK) or graphite-enhanced (λ=0.031 W/mK).

  • Adhesives: KLEIB C1, C2, C2 EXTRA, C2B (cement-based).

  • Base Coats: KLEIB C2 / C2 EXTRA / C2B.

  • Reinforcement: Standard fiberglass mesh (160 g/m²).

  • Finishes: Mineral, Acrylic, Silicate-Silicone, Silicone, Siloxane, or Mosaic renders.

  • Decorative Paints: Acrylic, Silicate, Silicone, or Siloxane top coats.

  • Fixings: ETAG 014-compliant anchors + stainless steel fixings for fire safety.

  • Ancillary Items: Beads, primers, sealants, starter tracks, and profiles.
