Questions and answers

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.

Composite rebar is essential for creating durable structures that are not subject to degradation over time. Today, it is the most technologically advanced and cost-effective rebar available.

• Strength — composite rebar has tensile strength characteristics 3 times higher than those of A500C class steel rebar.
• Durability — the thermal expansion coefficient of composite rebar is close to that of concrete, which prevents micro-deformations and micro-cracks in the concrete structure, significantly increasing the overall durability of the structure.
• Chemical resistance — composite rebar has high chemical resistance in various aggressive environments; it is not subject to corrosion, which also positively affects durability.
• Lightweight — fiberglass rebar with comparable strength characteristics is 9 times lighter than steel rebar.
• Low thermal conductivity — thanks to low thermal conductivity, no "cold bridges" form in structures, reducing heat loss by up to 34% and consequently — heating costs for the building.
• Ease of installation — rebar rods can be cut from a coil to any required length and fastened with plastic ties or special fixing clips, not just binding wire.
• Ease of transportation and storage — rebar can be coiled, allowing even passenger cars to be used for transport, resulting in significant savings.

ETIZ Composite rebar has higher physical and mechanical properties and consistent quality — due to the raw materials and components used from the best manufacturers and advanced technology. It is stronger and more durable at the same diameters. ETIZ Composite rebar exceeds the requirements of GOST 31938-2012 with a margin.

ETIZ Composite does not have the ability to track projects where our customers have used composite rebar. If desired, information about such projects can be found on the Internet.

Composite rebar is a modern construction material designed for concrete reinforcement or strengthening of multi-layer wall masonry. Composite rebar is also called FRP (Fiber-Reinforced Polymer) rebar, or fiberglass rebar. Composite rebar is a rod with a spirally wound anchor layer of four strands protruding above the rod.

Foam glass is a new category of thermal insulation materials. ETIZ Foam Glass, like traditional foam glass, shares a similar raw material base, but the manufacturing technology and, consequently, a number of properties differ. Thanks to our unique development, we have not only preserved all the best qualities of foam glass but also achieved new properties: ETIZ Foam Glass has an open-pore structure for vapor permeability, allowing structures to "breathe"; an independent sound insulation coefficient of +27 dB, and sound absorption of class "A" (the highest). All of this is very important for comfortable living, health, and safety. Moreover, ETIZ Foam Glass is significantly cheaper than other foam glass products available on the Russian market.

ETIZ Foam Glass is completely non-combustible (NG group). It withstands open flame without changes in geometry, volume, or deformation. Under high temperatures, it does not emit harmful gases (mass loss equals zero). Melting point is 1,350°C. Upper operating temperature limit is 750  °C. Thanks to this fire resistance, the material can locally contain fire.
Fire resistance of ETIZ Foam Glass is 90 min (180 kg/m³ board).
