Building cladding terms
plainly defined
Professional definitions for the terms you will meet on every cladding project. Alucobond, panel types, fire codes, installation systems and fabrication technology. Written for architects, developers and owners who want to speak the same language as the contractor.
- A2 — Non-combustible core
- Pure mineral core per EN 13501-1. Does not burn. Required for high-rises, public buildings and any project under the strictest fire safety regime.
- ACP — Aluminum Composite Panel
- Composite cladding panel of which Alucobond is the leading example. Two aluminum skins bonded over a core of polyethylene, fire retardant, or mineral material.
- Alucobond
- Brand name for an aluminum composite panel (ACP) built from two thin aluminum skins coated in PVDF with an inner core. The modern global standard for facade cladding.
- BIM modeling
- Building Information Modeling. 3D facade modeling before installation. Detects clashes with other trades and saves time on site.
- CNC fabrication
- Computer Numerical Control. Automated cutting and folding that produces Alucobond panels at millimeter precision. Essential for sharp corners and hidden joints.
- Code 921
- Israeli Standard 921 for cladding fire safety. Sets requirements for panel grade, installation system, fire stops and insulation. Applies to multi-story residential, office and commercial buildings.
- Curtain wall
- Large-format glass facade system that is part of the building structure. Common on office towers. Often combined with Alucobond cladding for visual balance.
- FR. Fire Retardant core
- Core with mineral fire retardants. Meets Israeli code 921 for buildings up to nine stories. Common standard specification for mid-rise residential and commercial.
- PE — Polyethylene core
- Cheapest ACP core type. Flammable and not allowed above ground floor under most modern building codes. DAR GROUP does not use PE.
- PVDF coating
- Polyvinylidene Fluoride. The premium coating on Alucobond aluminum skins. Holds color under UV exposure, humidity and salt air for 20+ years.
- Rear Ventilated Facade
- Installation system that creates a continuous air gap between cladding panels and the structural wall. Improves thermal performance, drains moisture, dramatically extends facade lifespan.
- Tama 38
- Israeli national plan for retrofitting old buildings against earthquakes. Often includes full facade upgrade, which makes it the natural moment to install a new cladding system.
