A facade is the exterior face or “skin” of a building, serving both functional and
aesthetic purposes. It protects the building from weather elements (rain, wind, sun, and
temperature variations) while defining the architectural character and visual identity of the
structure. Modern facades are engineered systems that integrate structural support, thermal
insulation, weatherproofing, natural light control, and design expression. At Alufacade World, we
specialize in high-performance facade systems, including curtain walls, ACP cladding, glass
envelopes, and hybrid assemblies designed specifically for East Africa’s tropical climate.

The main facade systems we install in East Africa include:

• Curtain Wall Systems: Non-structural glazing systems (stick-built or unitized) using aluminum
  frames and glass panels
• ACP (Aluminum Composite Panel) Cladding: Lightweight panels with fire-rated cores, ideal
  for commercial buildings
• GRC (Glass Reinforced Concrete): Textured concrete panels for decorative facades
• Stone Cladding: Natural stone or engineered stone panels
• Louvers & Sunshades: Solar control systems that reduce heat gain
• Hybrid Systems: Combinations of glass, metal, and cladding materials
  Each system has specific performance characteristics, cost implications, and aesthetic qualities
  suited to different building types and project requirements.

Curtain Wall: A non-load-bearing exterior wall system attached to the building
structure. It carries its own weight and wind loads back to the building frame, but does not
support floor or roof loads. Typically consists of aluminum frames and glass panels.
Cladding System: A protective covering applied to the exterior of a building, which can be
structural or non-structural. Examples include ACP panels, stone, GRC, or metal panels
attached to a subframe or directly to the building structure.
Key Differences:

• Curtain walls are primarily glass; cladding can be opaque materials
• Curtain walls span multiple floors; cladding is often panel-by-panel
• Curtain walls provide vision/daylight; cladding typically does not
• Cost: Curtain walls generally cost more per square meter
  Both systems can be combined in hybrid facades for optimal performance and aesthetics.

With proper installation and regular maintenance, facade systems in East Africa
typically last:

• Curtain Wall Systems: 25-35 years (aluminum frames can last 40+ years)
• ACP Cladding: 20-30 years (PVDF-coated panels last longer than PE-coated)
• Glass Units (IGUs): 15-25 years (depending on seal quality and UV exposure)
• Sealants & Gaskets: 10-15 years (require periodic replacement)
  East Africa’s intense UV exposure and tropical rainstorms can accelerate deterioration, making
  specification quality and regular maintenance critical. We recommend annual facade inspections
  and cleaning to maximize system lifespan and performance.

Yes, facade systems require regular maintenance to ensure longevity and
performance. At Alufacade World, we recommend:
Annual Maintenance:

• Visual inspection for damage, delamination, or deterioration
• Cleaning (especially in urban/industrial areas)
• Sealant joint inspection
• Drainage system check
  Every 5-10 Years:
• Detailed performance assessment
• Sealant replacement (silicone sealants degrade after 10-15 years)
• Hardware adjustment and lubrication • Water penetration testing
• Every 15-20 Years:
• Major refurbishment consideration
• Insulated glass unit (IGU) replacement if seals fail
• Panel replacement if delamination occurs
  Proper maintenance prevents water ingress, reduces energy costs, and extends facade lifespan
  by 10-15 years. We offer comprehensive maintenance contracts for all our installations.

Aluminum is the preferred material for facade systems in Kenya due to:
Performance Benefits:

• Corrosion Resistance: Excellent for coastal environments (Mombasa) and humid climates
• Lightweight: Reduces structural loads, easier to handle and install
• Strength: High strength-to-weight ratio supports large glass panels
• Durability: Lasts 30-40+ years with minimal maintenance
  Design Benefits:
• Flexibility: Can be extruded into complex profiles
• Finish Options: Powder coating, anodizing, wood grain effects
• Slim Profiles: Maximizes glass area and views
• Thermal Breaks: Integrated insulation reduces heat transfer
  Sustainability Benefits:
• 100% Recyclable: Can be recycled indefinitely without quality loss
• Energy Efficiency: When combined with low-E glass, it reduces cooling costs by 20-40%
• Local Availability: Systems like Technal and Alumil are readily available in East Africa

Yes, properly specified facade systems can significantly reduce building energy
consumption:
Energy-Saving Strategies We Implement:

1. Low-E Glass (Low-Emissivity):

• Reduces heat gain by 30-50% vs. standard glass
• Blocks infrared radiation while allowing visible light
• Critical for Kenya’s tropical climate

1. Double Glazing / Insulated Glass Units (IGUs):

• Reduces heat transfer through glass by 40-60%
• Air gap acts as thermal insulation
• Can include argon gas fill for better performance

1. External Shading (Louvers, Fins, Sunshades):

• Blocks direct sunlight before it hits the glass
• Reduces cooling loads by 25-35%
• Maintains natural daylight.

1. Ventilated Facades:

• Air cavity behind cladding creates thermal buffer
• Natural convection removes heat before it enters the building
• Reduces facade surface temperature by 10-15°C
  Typical Savings in Nairobi: A well-designed facade can reduce HVAC (cooling) costs by
  25-40% compared to single-glazed systems, with payback periods of 5-8 years through reduced
  electricity bills.

Selecting the optimal facade system requires evaluating multiple factors:

1. Climate & Environmental Conditions:

• I.e:Nairobi: High UV, moderate rain → Low-E glass, UV-resistant coatings
• Mombasa: Coastal humidity, salt air → Corrosion-resistant materials
• Highland areas: Temperature fluctuations → Thermal breaks, expansion joints

1. Building Type & Use:

• Commercial/Office: Curtain wall for daylight, ACP for branding areas
• Residential: Aluminum windows with ACP cladding for privacy
• Retail/Malls: Large glass areas with shading systems
• Hotels: Mix of glass and cladding for aesthetics + privacy

1. Performance Requirements:

• Fire safety: Fire-rated ACP cores, fire-resistant glazing
• Energy efficiency: Low-E glass, double glazing, shading
• Acoustics: Laminated glass for noise reduction
• Security: Laminated/tempered glass, restricted access

1. Budget:

• Initial cost vs. lifecycle cost (energy savings, maintenance)
• Value engineering options

1. Aesthetic Vision:

• Architect’s design intent
• Material finishes and colors
• Building identity and context
  Our team provides facade consultancy to analyze these factors and recommend the optimal
  system for your project. We use BIM modeling and thermal simulation to validate performance
  before installation.
