Why does a building need exterior cladding at all?
The structural wall of a building, whether block, concrete, or a steel frame, was not designed for direct climate exposure. Israeli sun, winter humidity, sea salt, and temperature swings erode internal materials quickly. Exterior wall cladding is a protective layer that pushes wear away from the structure and preserves the building life expectancy.
Beyond protection, cladding determines the building appearance. A building with quality cladding signals value, professionalism, and care. A building with faded plaster or worn cladding signals the opposite. In the Israeli real estate market, a refreshed facade adds notable percentage points to property value.
What is the difference between Alucobond, stone, porcelain, HPL and render?
Five cladding materials dominate the Israeli market, and the difference between them is not only price. Weight, reaction to fire, service life and maintenance frequency vary by orders of magnitude, and those are what decide which material suits which building.
Alucobond (ACP) is the modern standard: light, design-flexible, 25 years of service life and suitable for almost any building type. Natural stone gives a luxury appearance but weighs ten times as much and needs a supporting structure. Architectural porcelain is non-combustible and highly durable, but brittle and dependent on a dedicated anchoring system. HPL is cheaper and looks good, but has a shorter service life and a lower fire classification. Acrylic render is the cheapest and lasts 8 to 12 years.
What sets the price
We do not publish price bands, because the number changes from project to project. These are the factors that move it most:
- Facade geometry. The number of openings, corners and folds per m². A large flat elevation costs far less per m² than a detailed one.
- Substrate condition. On an existing building this is the hardest item to judge remotely, and the one that surprises people in cheap quotations.
- Access equipment. Standard scaffolding, a suspended platform or rope access. At height this is a significant line of its own.
- Panel grade and finish. Fire-retardant or mineral core, and a standard finish versus metallic, wood-effect or a custom RAL colour.
- Project size. A larger area lowers the cost per m² through repetition and installation efficiency.

How to read the table: weight determines whether the structure needs strengthening. Reaction to fire determines whether the material is permitted on the building at all. Service life determines how many times you will pay for scaffolding again. The full 25-year cost calculation is in Alucobond vs render and stone, and the aluminium options are compared in aluminium composite vs solid aluminium cladding.
How do you choose a cladding system?
The first criterion is reaction to fire. Israeli Standard 921 covers reaction to fire of building materials, and the grade for a given project is set in its specification. On towers, public buildings and hospitals an A2 mineral core is the customary specification. Elsewhere, FR is the accepted specification. A contractor who will not state the classification of the panels they propose is a red flag.
The second criterion is the installation system. A rear ventilated facade with aluminium sub-framing and thermal insulation is the professional standard: it creates an air cavity that drains moisture, insulates thermally and protects the structure. A cheap adhesive-and-screw installation on a timber substrate negates almost every meaningful benefit of cladding.
How much does exterior wall cladding cost per square meter?
Cost depends on material, installation system and geometric complexity. Israeli market ranges for 2026, including material and labour and before VAT: acrylic render a project-specific figure, HPL 450 to 750, architectural porcelain 600 to 950, Alucobond FR with a rear ventilated facade 750 to 1,100, Alucobond A2 850 to 1,300, and natural stone 1,200 to 2,000.
These prices exclude scaffolding, substrate repair before installation, special logistics and VAT. On projects above 1,000 m² the rate per m² falls. On small facades with difficult access it rises. Enhanced thermal insulation adds a project-specific figure.
The full breakdown of what moves the price within the band, and how to read a quote, is in our Alucobond cladding cost guide. Renovation costs for an existing building are covered in the facade renovation guide.
How much maintenance does each cladding need?
An Alucobond facade with PVDF coating lasts 25 years with minimal color fade. Required maintenance is washing with water every 2 to 3 years. No additional treatment. The right contractor provides a written warranty on color stability and system integrity.
Other cladding types demand more. Natural stone needs resealing every 7 to 10 years. Plaster needs renewal every 8 to 12 years. Glazing needs frequent cleaning. The cheapest cladding at the start is usually the most expensive over 25 years.
What does Israeli regulation require from a facade?
Two main requirements. First, reaction to fire under IS 921: the standard classifies the panel, and the required class is set by the building classification. On towers the customary specification is A2, and the same applies to public buildings, hospitals and schools at any height. The installation system must also include fire stops at every floor level and around every opening.
Second, thermal insulation under IS 1045. New construction must meet minimum envelope insulation values. The practical route to compliance is a rear ventilated facade with a mineral insulation layer. Cladding is not only aesthetic; it is part of the building’s thermal envelope.
Key takeaways
- Five main materials: Alucobond, stone, porcelain, HPL and render. Choose first on fire class and weight, then on price.
- 2026 price bands: render 180 to 250, HPL 450 to 750, porcelain 600 to 950, Alucobond 750 to 1,300, stone a project-specific figure.
- Stone weighs ten times as much as Alucobond and needs a supporting structure.
- On towers and public buildings: A2 mineral core.
- The installation system matters as much as the material. Without a cavity and fire stops, the cladding does not comply.
By building type: private villa cladding, residential buildings and towers, office and hi-tech buildings, retail and commercial, or facade renovation. Technical terms are defined in our cladding glossary.
Frequently asked questions
How long does quality exterior cladding last?
Alucobond with PVDF coating lasts 25 years or more with minimal color fade. The installation system (sub-framing, fasteners, insulation) is engineered for the same lifespan. Maintenance: water washing every 2 to 3 years, no painting or additional treatment needed.
Can an old building be re-clad without evacuating residents?
Yes, in most cases. Exterior cladding work is performed from external scaffolding without requiring access to apartments. Only when major structural repairs are needed is there resident coordination. DAR GROUP specializes in working without disrupting daily life.
What is the difference between cladding and insulation?
Cladding is the visible exterior protective layer. Insulation is a thermal material layer between the structural wall and the cladding. In a proper rear ventilated facade system the two work together. Insulation reduces heat transfer, cladding protects it from climate and preserves aesthetic appearance.
Who is responsible for maintaining a multi-unit building facade?
The house committee or management company is responsible for shared facade maintenance. Renovation costs fall on all residents per ownership share. For major projects, legal consultation on the required majority for cladding work approval is recommended.
