The technique of beautifying masonry using plaster has been used since the 1st century AD in Pompeii, and it has been refined over time. Various plastering styles were tried and perfected down through the years. These methods bring us to the current state of the technique and are used by well-trained building craftsmen.

Exterior Insulation Finishing System (German: WDVS) is, by contrast, relatively new and has only been commercially available since the late 50s. Over the years, it has been further developed and is continually being improved upon due to high production standards and better training among the companies engaged in it.

The establishment of professional associations and quality control groups has also ensured increased functionality and durability of systems through the development and adaptation of constantly improving information and application guidelines

Over the years, many types of insulation such as cork, wood fibre, hemp, reeds, and mineral foam have been developed and brought to market.

These products rarely established themselves amongst general consumers, however.

To date, two basic types of EIFS dominate the market.

Both systems differ primarily in the insulation material used. EIFS using mineral wool slab is available exclusively in the thick layer system with either 5mm or 8mm flush. Whereas EIFS with EPS slabs can also be processed in the thin layer system with 3mm flush.

The covering layer can be applied in an almost infinite array of colour, graining and polishing variants. You can see a selection in our sample testimonials section.

EIFS with Mineral Wool Slabs

A-WDVS MWPT

awds_mwpt

Mineral wool slabs can be taken to mean glass wool or rock wool; for outdoor applications, however, only rock wool is used for the most part.

During manufacture, rock or glass is liquefied through heating and passed through special sieves or drums to make fibres.

These fibres are then pressed into slabs with binders.

Advantages:

  • excellent fire behaviour
  • good sound insulation
  • good diffusive properties
  • high availability of raw materials
  • low energy requirement during manufacture.

Disadvantages:

  • heavy
  • expensive to process.
  • poor reusability
  • high price

EIFS with expanded or extruded polystyrene

A-WDVS EPSF

a-wdvs_wpsf

EPS insulation slabs are purely a crude oil product and are manufactured out of polystyrene.

For this, polystyrene granules are usually foamed into rectangular shapes with water vapour. The slabs are then cut from these rectangles into various thicknesses.

Advantages:

  • good insulation properties, improvable by approx. 20% through the addition of graphite
  • easy processability
  • long life
  • good reusability / recycling properties
  • low weight

Disadvantages:

  • high energy expenditure during production
  • poor fire behaviour
  • poor sound insulation
  • limited resources
