The fiberglass-reinforced plastic, hereinafter referred to as GRP is a multilayer prefabricated component consisting of a thermal insulation layer and / or load-carrier layers of different thicknesses and a GRP reinforcement around it.


High-gloss or mat in different colours
Surface structure can be smooth, squared fabric structure or anti-slip grinsor even carbon fiber
Very high tensile strength
With special coatings: UV resistant, extra abrasion resistant or even antibacterial


PUR / PIR, XPS, PET, PP Honeycomb, Plywood birch, Metal, IBV


At IBV Hungária Kft., we have been producing GRP sandwich panels since 2018. Colleagues with decades of GRP sandwich panel manufacturing experience are involved in the design and management of the technology and help our customers find the most appropriate solutions.

The process of sandwich panel production starts with cutting GRP sheets from rolls and sizing the core materials and integrated inserts. The prepared components are built on a 9 x 3 m vacuum table where a special 2-component PU adhesive is applied between the layers. Thereafter, a vacuum compresses the individual layers together until the adhesive has set, thus ensuring the flatness and uniform thickness of the sandwich panel.


The advantage of the GRP armored panel over the traditional metal armored sandwich panel is the corrosion resistance and the increased load-bearing capacity characterized by different types of core materials. The structure of the sandwich panel can be 100% customized according to the functionality and the application way.

The tensile strength of the GRP armament is several times higher than of the steel in terms of self-weight, so that is highly resistant to various forms of stress, weather and abrasion.

The GRP sandwich panel can be sized in the same way as wood with simple hand tools.

One-component MS Polymer adhesives adhere extremely well to the GRP surface.

Prefabricated e.g. glued application of corner profiles not only ensures quick installation and aesthetic appearance, but also has an extremely strong bond.
Tightening screws can be easily applied with wood, metal or PET reinforcements integrated in the GRP sandwich panel.
