The Metfiber® Eco Wall panel with a glass wool core fulfils all the requirements for non-combustible building materials. The glass wool used in this product consists of 80% recycled material, contributing significantly to the saving of natural resources and making the product an ecological building material.

The deadweight of the panel is distinctly lower than that of conventional sandwich panels with a rock wool insulation core, hence enabling an easier, faster installation and cost reduction, especially for longer panels.

Due to the large number of combinations with other panels from our portfolio with polyurethane or rock wool insulation core, it is possible to reach fire-safety, acoustic and thermal requirements at once without any visual impact.

Please have a look at our detailed technical manual for further information.

Building material classified as A2-s1, d0 non-combustible according to DIN EN 13501-1

Thermal Conductivity

λ=0,039 W/m.K under the terms of DIN 4108 and DIN EN 13162

Sound Insulation

Rw ≥ 31 dB

Corrosion Protection

  • Standard version with external and internal steel sheet of 25 μm polyester
  • External and internal steel sheet: category RC3 (under the terms of DIN EN 10169)
External sheet: corrosive category C3 corresponding to average duration of protection for urban and industrial environments with moderate exposure to sulphur dioxide
Internal sheet: corrosivity category C3 for rooms with high humidity with moderate strain, i.e. food production, laundries, breweries and dairy factories. Other coating systems are available for more sophisticated demands such as buildings near the sea, farm buildings with high ammonia exposure or moist rooms.
(Conditions of surroundings and corrosivity categories under the terms of DIN EN ISO 12944-2)
