Thanks to the abundance of modern building materials and technologies, restrictions on the choice of the facade of the building — residential, industrial, commercial, administrative, etc. — have disappeared. The facades are stone and brick, made of porcelain stoneware, siding and fibre-cement panels. By type of installation, they are divided into vented and unventilated, but in any case when working with them a composite fiberglass rebar is used.

Why non-metallic rebar?

Non-metallic rebar are composite products made of glass or basalt fiber with the mandatory addition of epoxy resin as a binder. When comparing steel and fiberglass rebar in a winning position is a non-metallic building material.

Main advantages:

  • corrosion resistance, preserving the original properties in an aggressive environment;
  • increased strength (fiberglass is at least 3 times stronger than metal, 4 times lighter in this case, therefore, there is no load on the foundation and walls);
  • high thermal conductivity serves as a protection against penetration of heat into the structure at low air temperatures;
  • radio transparency, that is, the ability to transmit radio waves in a wide frequency range without loss and interference;
  • low transportation costs, loader services and specialized equipment, cutting and installation.

A unique property of fiberglass reinforcement is one hundred percent physical memory. After unrolling the coil, the products become straight, ready for use in facade work.

Some rules for working with flexible connections for facades

Today, fiberglass rebar and flexible connections are used not only for the construction of walls, but also for the organization of the facade. The length of the bars is selected individually, based on the type of building material and the thickness of the thermal insulation layer.

In this case, you must adhere to certain rules:

  • to ensure adhesion to the cement or adhesive solution, the rods have periodic wound belts along the entire length or special anchor hooks at the end;
  • if it is planned to leave an air gap between the wall and the heater, it is desirable to use flexible connections made of fiberglass, additionally equipped with a clamping plate;
  • working with the facade of a blind wall, it is necessary to establish flexible connections in a quantity of at least 4 pieces. per 1 square meter;
  • Auxiliary rods are installed in places of increased load, near the expansion joints, along the perimeter of window and door openings.

With these requirements and rules it is better to read through the special documentation, including the building codes. You can also consult with the «MRG-Composites» staff.

Use of clamps for composite rebar

To achieve a high result in the facade work, composite glass fiber reinforcement should be supplemented with special fixatives. Their range is wide enough, and each variety has its own characteristics. For example, the lock «Star» creates a protective layer between the reinforcement and the formwork, it is used when working with vertical structures. Fixers under the names «Cube» and «Stool» also provide a protective layer from 10 to 40 mm and are used in combination with a non-metallic reinforcement with a diameter of 5-20 mm.
Each of the listed products differs plasticity and strength, that is why it does not deform when changing the temperature regime. It is acceptable to use at any time of the year.
