Build today for tomorrow's world with innovative XERAL insulating materials.

At times of scarce resources, innovative and novel building materials are the focal challenge.

The modern building world is in flux. The solving of future issues concerning architecture and construction of buildings, structures and residential estates is equally a question of novel building materials and of their intelligent use.

For the properties of tomorrow forward-thinking planning as well as the application of innovative materials and processes are in the focus of builders and clients. Research into and development of energy-efficient materials and components form the basis for the XERAL product range. The development of ideal building materials taking ecology and health into account is our everyday activity.



What makes XERAL so special?

All XERAL products are mineral insulating materials i.e. they are non-flammable, completely recyclable and removable. Compared to synthetic-based insulating materials such as EPS insulating plasters (expanded polystyrene) an all-mineral insulating material is non-flammable.

Why were EPS and PU materials not considered for the development of XERAL?

EPS insulating materials consist of polystyrene. Polystyrene is a synthetic thermoplastic material. Polystyrene is a transparent, in foam form, white-coloured synthetic material the base material of which consists of styrene. Because styrene is manufactured from mineral oil the XERAL products refrain from using this non-sustainable material.

PUR or PU insulating materials consist of the synthetic material polyurethane, often known as synthetic resin. (Symbol PU, to DIN: PUR). Its classification within the building material classes C-s3, d0 to E according to European standard DIN EN-13501-1 is attributable to its flame resistant or normally flammable fire behaviour. This is aggravated by the fact that toxic gases are formed when destroyed by fire. During the ageing process of Polyurethane boards shrinking of the material could be observed which can result in the formation of fissures. This effect can also lead to brittleness of the material and impair the thermal insulation as well as promote the formation of condensation.

By virtue of the abovementioned material characteristics as well as on ecological, qualitative and building physical grounds the use of synthetic materials was excluded from the development of XERAL products.

Mineral thermal insulating plasters from XERAL attain peak values for heat insulation. With a thermal conductivity of up to 028 XERAL insulating materials perform better than almost all existing external thermal insulation composite systems and are both ecological as well as economical.

The unconditional commitment to mineral raw materials combined with technical innovation strength ensure high quality of the XERAL product range.
