The elastic modulus is a key indicator of stiffness. Polycarbonate (2,200–2,600 MPa) is flexible and impact-resistant, making it ideal for arched structures, canopies, and complex-shaped translucent coverings. Its ability to bend without breaking opens wide design possibilities. Fiberglass (5,500–7,800 MPa), thanks to reinforcement, is 2–3 times stiffer. This property allows creating roofs and canopies with increased sheathing spacing, saving materials and reducing the overall weight of the structure. Thus, the choice is determined by the engineering task: where flexibility is needed, polycarbonate is chosen; where the priority is load-bearing capacity and minimal deflection, fiberglass is preferred.

The approach to UV protection is fundamentally different. Polycarbonate is protected by a co-extruded layer — an effective but localized barrier. Its damage leads to rapid degradation of the material in that area. Fiberglass uses a multi-level protection system: UV-resistant resin throughout the mass, surface gelcoat, and barrier film. This combination provides resistance not only to sunlight but also to chemicals, and damage to the top layer does not lead to instant destruction of the entire sheet. The comprehensive approach lays the foundation for a longer service life of fiberglass (25+ years) compared to polycarbonate (15–20 years) under intense insolation conditions.

The choice in favor of fiberglass is driven by its specialized advantages critical for agro-industrial complexes. Its main advantage is creating diffused light that uniformly penetrates deep into the canopy, unlike the directed light of polycarbonate. Such illumination prevents plant burns and stimulates photosynthesis, which directly increases yields. Furthermore, fiberglass is chemically inert to pesticides, fertilizers, and aggressive washing, whereas polycarbonate can become cloudy and crack. Low thermal expansion ensures geometric stability and airtightness of a large greenhouse during temperature fluctuations, making operation more reliable and predictable.

COMPOGLASS is a composite sheet material used in facade structures, exterior cladding, and interior finishing of buildings for various purposes.

The material is used for cladding commercial and industrial structures, manufacturing advertising structures and signage, as well as in interior solutions where reliability and a neat appearance are important.

Yes, composite sheets are suitable for facades and ventilated facade systems. They are resistant to external influences and designed for long-term outdoor use.

The advantages of the material include ease of installation, low weight, high strength, resistance to the environment, and a long service life without loss of performance characteristics.

The composite sheet maintains its strength characteristics under mechanical and vibration loads, while its low weight reduces the load on structural elements compared to traditional materials.

The material is not subject to corrosion, is resistant to fading, chemical and biological factors, which allows it to maintain its appearance for many years.

With proper installation and operating conditions, the service life of the composite sheet can reach 50 years without deterioration of its properties.
