Frequently Asked Questions: Everything Kenyans Need to Know About Aluminium Curtain Walling [2025 Update]
Introduction: Why Aluminium Curtain Walling Matters in Kenya
Aluminium curtain walling has become a standout feature in Kenya’s modern buildings—from the skyscrapers of Upper Hill to luxury apartments in Kilimani. But for many Kenyans, it still raises questions: Is it affordable? Is it suitable for our climate? What are the long-term benefits?
This in-depth FAQ guide is designed to answer all your burning questions, whether you’re a property developer, architect, contractor, or simply a curious homeowner.
General Overview of Aluminium Curtain Walling
What Is Aluminium Curtain Walling?
Aluminium curtain walling is a non-load-bearing exterior façade system composed of aluminium frames and glass or composite panels. It “hangs” from the main structure like a curtain, providing insulation, weather resistance, and aesthetics without adding structural load.
How Is It Different from Traditional Walls?
Unlike traditional brick or concrete walls, curtain walls:
Do not bear weight
Offer better daylight access
Provide improved thermal and sound insulation
Are lighter and more flexible in design
Performance and Benefits
Is It Energy-Efficient?
Yes. With proper glazing (such as Low-E or double-glazed units), aluminium curtain wall systems significantly reduce heat transfer, helping to lower energy costs by 20–40% depending on the region.
How Does It Handle Kenya’s Climate?
Aluminium is naturally corrosion-resistant, making it ideal for both humid coastal cities like Mombasa and cooler inland areas like Nairobi. Modern curtain walls also reduce heat gain and retain indoor comfort efficiently.
Does It Reduce Noise Pollution?
Absolutely. Curtain walling systems with acoustic glazing block external noise, which is especially valuable in busy areas like Westlands, CBD, or Thika Road.
Installation and Design Queries
What Are the Types of Curtain Wall Systems?
Stick System: Assembled on-site, best for smaller buildings.
Unitized System: Pre-fabricated panels installed as units, ideal for high-rises.
Each has advantages in terms of cost, time, and complexity.
Can It Be Used for Residential Homes in Kenya?
Yes. While commonly used in commercial buildings, many luxury homes and apartments now use curtain walling to enhance aesthetics and energy performance.
What Design Options Are Available?
Curtain walls offer a wide range of customization:
Frameless or structural glazing
Colored or tinted glass
Louvers, fins, and smart glass options
Cost and Budgeting
What’s the Average Cost per Square Meter in Kenya (2025)?
Depending on glazing type and design complexity:
KES 15,000 – 25,000 per sqm for residential projects
KES 20,000 – 35,000 per sqm for commercial and high-rise developments
Is It More Expensive Than Brick or Stone?
Yes, initially. However, it offers long-term savings through:
Lower maintenance
Reduced energy bills
Increased property value
Are There Financing Options Available?
Yes. Some banks and SACCOs now finance green building projects, including aluminium curtain walling, as part of broader construction loans.
Sustainability and Environment
Is Aluminium a Green Building Material?
Absolutely. Aluminium is 100% recyclable, and most local fabricators use recycled content. It supports Kenya’s move toward low-carbon, resource-efficient construction.
Can Curtain Walling Help with LEED or EDGE Certification?
Yes. Curtain walls contribute points in categories like:
Energy efficiency
Sustainable materials
Indoor environmental quality
Many green buildings in Nairobi use curtain walling to qualify for certifications.
Local Market and Suppliers
Are There Reliable Aluminium Fabricators in Kenya?
Yes. Notable local players include:
Prime Aluminium
Aluminium Africa Ltd (Alafrica)
Crystal Aluminium
They offer customizable, high-performance systems with professional installation.
What Should I Look for in a Supplier or Contractor?
Proven project experience
ISO-certified systems
Warranty and maintenance support
Good references and client reviews
Maintenance and Longevity
How Long Does a Curtain Wall System Last?
Aluminium curtain walls have a lifespan of 40–50 years with proper care, outperforming many traditional materials.
Is Maintenance Expensive or Complicated?
No. Maintenance involves:
Annual cleaning
Sealant inspections
Occasional glass replacements
Budget around KES 300 – 600 per sqm/year for upkeep.
Common Misconceptions Debunked
“Curtain Walls Are Too Fragile”
False. Modern systems use laminated or tempered safety glass that’s impact-resistant and safe under extreme weather.
“They Only Work in Skyscrapers”
Not true. Curtain walls are used in everything from bungalows to shopping centers, depending on design goals and budget.
Legal, Regulatory, and Safety Standards
Do Curtain Walls Meet Kenyan Building Codes?
Yes. They comply with standards set by the National Construction Authority (NCA) and local municipal regulations on façade safety, wind load, and energy performance.
Are They Fire-Resistant and Safe?
Yes, when installed with fire-rated glass and sealants. Many systems are tested for smoke resistance, flame spread, and impact resistance, ensuring occupant safety.
