Application

  • Lightweight, eco-friendly thermo-plaster for indoor and outdoor applications, suitable for thermal insulation and dehumidification.
  • It solves the problems related to thermal bridges and moulds induced by humidity, ensuring a healthy environment and a high living comfort.
  • Diathonite Thermactive.037 is comprised of natural compounds, and it is suitable for buildings where moisture vapour diffusion open and water capillary active (breathable) materials are required.
  • Can be used on a variety of substrates (historical brick, stone, blockwork, wood wool boards, and timber).

Description

Diathonite Thermactive.037 is an eco-friendly Exterior Insulation Finishing System - EIFS, whose main ingredients are granulated recycled cork, expanded amorphous silica, perlite and pumice combined in a balanced particle size distribution curve (0–3 mm). Natural hydraulic lime NHL 5 and hydrated lime are also present in the compound; therefore, the product is antibacterial and highly resistant to the formation of moulds and fungi.

Diathonite Thermactive.037 is a highly porous, light-weight, breathable, thermal insulation plaster; it has an excellent reaction to fire performance (non-combustible - Euro Fire Class A1); it is not damaged by dampness, and it is recyclable as an inert at the end of its life cycle. This thermo-plaster offers a versatile, monolithic and highly resistant solution to protect buildings from cold and hot weather. It contributes to the thermo-hygrometric comfort of indoor spaces, and it maintains its characteristics over its lifespan. The product is installed by a plastering spray machine or by trowel.

Features and benefits:

  • Water capillary active
  • High breathability and high porosity
  • Insulates from cold and heat, ensuring good thermal lag, up to 12 hours depending on the characteristics of the wall.
  • Lightweight.
  • Highly resistant to mould and condensation.
  • Absorbs and releases the excess humidity.
  • Suitable for historic restoration.
  • Protects masonry over time.
  • Contains recycled cork
  • Fast construction system (thermal brick + thermal plaster), and quick application (plastering machine).
  • Can apply onto curved walls
  • Made of a combination of natural hydraulic lime NHL 5 and hydrated lime (EN 459-1).
  • It can be applied on top of old lime plasters.
  • Reaction to fire: Euro Fire class A1 (EN 13501-1)
  • External insulation with no need for joints.
  • Product with double CE (EN 998-1, EN 998-2) and UKCA certification (BS EN 998-1, BS EN 998-2).
