Glossary

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.
