50mm White EPS External Wall Insulation Board (EPS70) is an easy to handle and install Expanded Polystyrene Insulation material used as a main component of external wall insulation systems and thin coat rendering.

White EPS (Polystyrene) 50mm is a lightweight basic insulation material available at reasonable prices that can effectively reduce heating costs and improve the appearance of the property.

Complete external wall insulation using white polystyrene is durable and maintains its functional properties throughout the entire life of the building.

External wall insulation systems based on polystyrene sheets for building facades are a proven solution that has been used in construction for over 50 years.

Expanded polystyrene is one of the most popular thermal insulation materials used to insulate building facades using the ETICS (External Thermal Insulation Composite System) method.

Polystyrene White EPS Board is a solid thermal insulation product often chosen by investors as a cheap external wall or floor insulating material.

White color reflects the sun better than grey, hence it is often not necessary to rasp the white EPS, saving several hours of work for an average installation.

Regardless of which type of polystyrene you choose, white or graphite (grey), remember that the key to proper thermal insulation of a building is its accurate installation, in accordance with the regulations and standards.

Preparations for the installation of white polystyrene:

There is no obligation to sand it before sticking due to good adhesive properties.

Rasping the polystyrene surface before sticking (regardless of its color) improves the adhesion of the adhesive to the fixing. 

The surface grinding operation must be performed on the upper side, before embedding the mesh.

What glue for white polystyrene?

Some manufacturers recommend gluing white polystyrene boards using a universal adhesive intended for embedding the mesh and for fixing polystyrene, not only polystyrene adhesive.

We recommend: Ceresit ZU Insulation Adhesive, Ceresit CT87 White Flexible Adhesive or Ceresit CT84 Express PU Foam Adhesive.

Experience shows that if we buy a really good polystyrene adhesive, it will work.

It is worth recalling that each polystyrene should be glued with the circumferential-point method. 

After applying the glue, it should be on at least 40% of the board surface. 

Dot and dab method should not be used anymore, but still many contractors stick polystyrene only to "dabs", insisting that they have been doing it for years and it is fine. 

This error can cause the boards to fall off, especially those made of graphite polystyrene.
