Future Applications for Osirys Products

Products developed within OSIRYS project present high potential and can be introduced in vast range of applications.

The most promising products are pultruded profiles and infused cladding panels based on bio resins and reinforcement made of fused natural and glass fibres.

FRP products are known for their extremely high mechanical properties as well as significantly low thermal conductivity. Components comprising bio materials preserve the same properties. In the OSIRYS project pultruded profiles are used as a structure for external wall elements (multilayer wall and curtain wall modules) and for internal partition walls. In future applications engineers can consider utilisation of pultruded profiles in other structures including balconies, staircases, footbridges. They can be used everywhere were high mechanical strength is required. Low thermal conductivity of pultruded materials only makes the material more attractive and can be seen as a great alternative for commonly used structural materials like steel or wood. Wide utilisation of FRP materials can be noticed while investigating US market where pultruded structures are used for creation of large-format sunscreens or even for production of façade ornaments and decoration elements (cornice).

Regarding infused panels, the most valuable implementation for this element in construction sector surely will be external cladding – light weight, durable structure and unlimited forming possibilities favours utilisation of infused elements in this application. Architects will receive material with which they will be able to practice their imagination and create new shapes which earlier were hardly achievable with currently used façade materials. However we shouldn’t forget that infusion technology is used not only in construction sector and is utilised to produce for instance race car seats or even whole boats. Certainly there will also be place for proper use of bio FRP materials outside construction sector.

Another innovative material developed in OSIRYS project is fire retardant panel produced through extrusion process out of bio HDPE and gypsum board wastes. Innovative formulation allowed to produce high quality fire protective 10 mm thick panels. In the project they will be used to cover external layers of multilayer wall modules to improve fire properties of building envelope. Significant stiffness of produced panels while maintaining low panel thickness allows them to be used in frames as well as in traditional structures. Panels can also be applied not only in new-built constructions (like in the OSIRYS project) but can be successfully utilised during buildings refurbishment and improvement of fire performance of certain areas. All building surfaces can be aided with fire retardant panels including ceilings and floors. This type of application can be especially useful for instance during transformation of abandoned constructions used in industry sector into dwellings when more strict fire regulations need to be fulfilled.

Within the OSIRYS project novel wood fibre panels were also developed as a bio-based material which will substitute widely implemented gypsum boards. They will be used as a lining on internal partition walls, however there are no restrictions to use wood fibre boards also in other applications like suspended ceilings. In general, traditional plasterboards used in constructions can be substituted with wood fibre boards. Although due to high mechanical strength of developed panels they can also be considered as a structure stiffening element. The construction sector may not be the only one which will take advantage of novel material. Wood fibre panels can also be an alternative for currently used wood based boards in the furniture industry.
