CLIA for composite panels: what it is and why it is needed

CLIA for composite panels: what it is in simple words

If you understand what is CLIA for composite panels, then this is not the cladding itself and not the frame, but the intermediate fastening link between them. The term is interpreted differently in practice, but in all cases it refers to the same class of products — the fastening or supporting element of the hinged facade system, which fixes the composite cassette (panel) on the guides of the subsystem. In everyday life, such elements are also called clemmers, staples or clamps, and they completely coincide in their role: hold the panel, set its position and transfer weight to the frame.

A composite panel is a “sandwich” of two thin sheets (usually aluminum or polymer) with an inner layer of filler. By itself, it is not attached to the wall: it is bent into a cassette and hung on the subsystem. This is where he comes into work Facade IKLYA — it enters the bent side of the cassette or presses the panel against the profile, keeping the lining in the design position.

Purpose and functions: why you need HCl

To understand why the system needs CLIA for composite panels, it is useful to look at the tasks that the attachment node solves. There are several of them, and all of them are equally important for the durability of the facade:

• Panel fixation. The main function is to securely hold the cassette on the frame and prevent it from shifting under its own weight, wind load and vibration.
• Compensation of temperature deformations. The composite and metal of the frame expand and contract with temperature changes. The unit is designed so that the panel can "breathe" — freely change dimensions without warping and clicks. Part of the fasteners is made movable, part — fixed.
• Flush mounting. In hidden systems, CCLI hides behind the panel or in its bend, so there are no visible self-tapping screws and rivets on the front side — the facade looks solid and neat.
• Load transfer. The weight of the cladding and the wind pressure through the fasteners are transmitted to the guides and further to the load-bearing wall, rather than being concentrated at one point of the panel.
• Maintainability. A well-designed assembly allows you to remove and replace a separate cassette, if necessary, without disassembling neighboring cassettes.

Where the CLI is located in the system: fixing the panels on the ventilation facade

To decompose how it works IKLYA panel fixing, let's present a standard "pie" of a hinged ventilated facade — from the outside it is going to the wall in layers:

1. Bearing wall — the base to which the entire system is mounted.
2. Halters — take out the frame from the wall and set the thickness of the air gap and the insulation.
3. Insulation and wind protection (in insulated systems) — located between the brackets.
4. Guide profiles — vertical (sometimes with horizontal) frame elements, to which the cladding is attached.
5. Fixing unit with CLIA — connects the panel to the guide.
6. Composite panel (cladding) — outer, visible layer.

Thus, the FCL is "at the junction" — between the guide subsystem and the edge of the panel. Depending on the design, it can snap onto the profile, be attached to it with screws or rivets, and connect to the panel through its bent side. At the same time, a ventilated air gap is maintained between the cladding and the insulation, for which the entire system is called a ventilated facade.

What makes up the fastening unit

A separate fastening unit usually includes the fixing bracket itself (FLA), fasteners to the guide (rivet or self-tapping screw) and, in a number of systems, additional elements — clamping strips, seals, heat compensation washers. The specific composition depends on the type of facade system and the manufacturer of the subsystem, so the set of components is always compared with the technical documentation of a particular solution.

Types and materials of IKLA facade

The term does not have an unambiguous single classification, but by function Facade IKLYA usually differs in two ways — in the method of fixing the panel and in the material. Let's describe it in general terms, without reference to specific brands and sizes.

The material is selected based on operating conditions: for a wet and aggressive environment, stainless or protected alloys are more logical, galvanized steel is used for typical conditions. The exact characteristics — metal thickness, permissible loads, anti-corrosion coating — always check according to the product data sheet and the calculation of a specific subsystem, and not according to general descriptions.

The role of the CLI in the installation of the facade of composite panels

During installation, the assembly with the CLI largely determines both the assembly speed and the final quality of the facade plane. The main points that are affected by fasteners:

• Plane geometry. Correctly aligned retainers set smooth seams and a single plane of the lining without "waves" and differences between the cassettes.
• Speed of work. Snap-in and typical units speed up the hanging of panels and reduce the risk of mounting errors.
• Durability Correct accounting of movable and reference points prevents the accumulation of stresses, due to which over time there are deformations and noise during heating.
• Maintenance The ability to remove a separate panel simplifies repairs and replacement of damaged elements.

It is important to remember: fasteners, subsystem and cladding are a single set. It is not necessary to mix the elements of different systems "by eye"; the attachment points, the pitch of the guides and the type of panel must be coordinated with each other and confirmed by the project.

COMPOGLASS CLIA & Translucent Composite Sheets

Translucent composite materials deserve special mention. While standard blind cassettes are typically made of metal composite, COMPOGLASS catalogue manufactured by ETIZ Composite are translucent composite sheets that are used where both light and protection are needed: canopies, visors, translucent roofing, fences and decorative facade inserts. The line includes profiled sheets (trapezium C-8, C-20, wave SV-38) and flat sheets, approximate thickness — from 0.5 to 4 mm, colors — transparent, bronze, blue, gray, green, with a glossy surface (check the exact parameters according to the product data sheet).

For translucent sheets, the principle of fastening is the same in logic — the lining is held on the frame by fasteners — but the specific type of assembly depends on whether it is a profiled sheet or a flat one, as well as on the purpose of the structure. For profiled sheets, a wave crest clamp with a seal is more often used, for flat ones — clamping strips and point fasteners with heat washers. Therefore, when selecting a fastener for a specific type of COMPOGLASS sheet, always focus on the installation recommendations and characteristics of the selected profile, and not on universal tips.

What to look for when choosing fasteners

So, having analyzed what is CLIA for composite panels, we will formulate a practical checklist. When choosing a fastening unit, focus on:

• compatibility with a specific subsystem and panel type (cassette, profiled or flat sheet);
• material and corrosion resistance to suit operating conditions;
• availability of movable points to compensate for temperature deformations;
• required type of installation — hidden or open;
• confirmed by the load calculation and the manufacturer's recommendations.

Always take specific dimensions, load characteristics and standards from the design and technical documentation for the system — general descriptions give an understanding of the principle, but do not replace the product data sheet and engineering calculation. You can choose translucent composite sheets for a canopy, roof or facade inserts in the section COMPOGLASS catalogue, and the type of fastening should be coordinated for the selected profile and the purpose of the structure.

FAQs

The needle for composite panels — what are these in simple words?

This is the fastening element of the hinged facade system — a clamp, bracket or retainer — by which the composite panel (cassette) is held on the guides of the ventilation facade subsystem. In fact, it is a "lock" between the cladding and the frame: it holds the panel and transfers the load to the supporting structure.

Why is CCLI needed and what functions does it perform?

The main functions are fixing the panel on the frame, compensating for temperature expansions (the panel can freely "breathe"), hidden installation without visible fasteners on the front side and transferring the weight of the lining with a wind load to the subsystem. Some of the nodes are made support, some are movable.

Where is the CLI located in the ventilation facade system?

Between the guide profile of the subsystem and the edge of the composite panel. It snaps or attaches to the rail, and connects to the panel through its curved bead or clamp, keeping a ventilated air gap behind the cladding.

What material is the facade fang made of?

Usually made of galvanized or stainless steel, as well as aluminum alloys, the material is selected for corrosion resistance and design load. Specify the exact material, thickness and coating according to the passport of a particular subsystem.

Is this mount suitable for COMPOGLASS translucent sheets?

The principle of holding the lining on the frame is the same, but the specific type of assembly depends on the type of sheet. For profiled sheets (trapezoid C-8, C-20, wave SV-38), a clamp on the comb with a seal is more often used, for flat ones — clamping bars and point fasteners with thermal washers. Match the type of fastening to the selected profile.

Is it possible to mix fasteners and subsystems of different manufacturers?

Not recommended. The fastening unit, the pitch of the guides and the type of panel form a single set and must be agreed with each other and confirmed by the project. Mixing elements "by eye" increases the risk of deformation and reduces the reliability of the facade.
