Initial installation cost
Plaster is the cheapest cladding system at installation. Material is inexpensive, labor is widely available, and the system has no engineered components to speak of. Natural stone sits at the upper end of installation cost, especially with premium materials and careful joinery. Alucobond falls between, closer to stone than to plaster.
Looking only at initial cost, plaster wins. But the comparison falls apart by year five.
Maintenance over 25 years
Plaster needs major refurbishment roughly every five to seven years in Israeli climate conditions. Repainting, patching, dealing with cracks and moisture damage. By year 25, a plaster facade will have been redone three to four times, each refresh involving scaffolding, paint and labor.
Natural stone requires periodic sealing, repointing of mortar joints and cleaning. The work is less frequent than plaster but more expensive when it happens. Some stones develop staining or efflorescence that requires specialized cleaning.
Alucobond requires essentially no maintenance. Periodic cleaning with mild detergent is enough. There is no repainting, no resealing, no annual treatment. Over 25 years, total maintenance cost is a fraction of either alternative.
Thermal performance
Plaster is a thin layer applied directly to the wall. It provides essentially no thermal benefit beyond a small reflectivity effect.
Natural stone is dense and heavy. It has thermal mass, which delays heat transfer, but it is not insulation. Without backing insulation, stone facades perform thermally about the same as bare concrete walls.
Alucobond, installed as a rear ventilated facade with insulation in the cavity, dramatically outperforms both. Cooling load reductions of 20 to 35 percent are standard, and the energy savings compound over the life of the building.
Lifespan and aging
Plaster has a useful life of 10 to 15 years before it needs significant work. Color fades unevenly, hairline cracks appear, water penetration starts to discolor the wall.
Natural stone, properly installed, can last decades. However, weathering is significant. Some stones erode, others stain. Mortar joints degrade. The aged look is sometimes desired, but it is not the same building you put up.
Alucobond holds its appearance with high precision for 25 to 30 years and often beyond. Panels do not warp, fade unevenly, or develop streaking. The building looks essentially as it did the day it was finished.
What is cheapest over 25 years?
Once installation cost and cumulative maintenance are added together, the four-fold gap of day one nearly disappears. Acrylic render lands at a project-specific figure, Alucobond FR at 830 to 1,280, and natural stone at 1,400 to 2,420. Render and Alucobond finish in the same order of magnitude, even though Alucobond costs four times as much to install.
Two things then decide the comparison in Alucobond’s favour, and both sit outside the table. First, at year 25 the Alucobond facade is still sound while the render facade is due for a third renewal cycle. Second, the energy saving of the ventilated facade, an annual saving measured per building, compounds to tens of thousands over the period.
- Render: cheap to install, two full renewal cycles with scaffolding, no thermal benefit
- Stone: expensive to install, moderate maintenance, weight requiring supporting structure
- Alucobond: mid-range install, minimal maintenance, real thermal benefit, life continuing past year 25
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.

Calculation assumptions: 2026 prices before VAT, undiscounted and with no inflation applied. Each render renewal includes scaffolding at a project-specific figure. Alucobond washing is priced at a project-specific figure per cycle. Natural stone assumes an existing supporting structure. The energy saving of the ventilated facade is deliberately excluded from the table — it is quantified in our guide to facade insulation and energy savings.
Key takeaways
- Installation: render 180 to 250, Alucobond FR 750 to 1,100, stone a project-specific figure.
- 25-year total: render 740 to 1,190, Alucobond 830 to 1,280, stone a project-specific figure.
- Render needs two full renewal cycles with scaffolding. Alucobond needs washing.
- The energy saving is not in the table, and it is what decides the comparison.
- If your holding horizon is under five years, render is still the right economic call.

Frequently asked questions
What does each material cost over 25 years?
At 2026 prices before VAT: acrylic render a project-specific figure (180 to 250 to install plus two renewal cycles with scaffolding), Alucobond FR with a rear ventilated facade a project-specific figure (750 to 1,100 to install plus washing every 2 to 3 years), and natural stone a project-specific figure. The calculation is undiscounted and excludes the energy saving.
Is render ever the right choice?
Yes, in two cases. First, a holding horizon under five years, before the first renewal cycle falls due. Second, a budget that cannot carry the initial investment and no financing route. In any other case, over a decade or more, the cumulative cost gap closes and Alucobond adds an energy saving that render does not provide.
What about combining materials?
Common and often the best outcome. A primary Alucobond facade with stone accents on entry features, or stone base courses with Alucobond above, can deliver design richness while keeping the lifecycle math favorable.
Does Alucobond ever look dated?
Color choice matters here. Bold accent colors and very trendy finishes can age out of fashion. Neutral metallic and solid color choices have proven timeless across 25+ years of installations. We advise toward restraint on the dominant facade.
How much value does a renewed facade add to a property?
Property appraisers treat quality cladding as a positive factor, mainly because of the low rate of deterioration and the impression it creates. Industry estimates put the effect in the low double digits in percentage terms against an ageing render facade, but there is no uniform measure and the figure depends entirely on the neighbourhood, the building type and its general condition. Ask for an appraisal on your specific property.
