I’ve spent several years working on glass curtain wall projects across Africa—office buildings, factories, hotels, commercial complexes, and facade renovations of older buildings. I’ve completed well over a hundred projects of all sizes. In Africa, frequent storms, heavy rainfall, and intense sunlight place far higher demands on curtain wall systems than in many other regions.
Yet I’ve noticed that many clients—developers, owners, and contractors—tend to fall into the same traps when selecting a curtain wall company. So let me share some honest, experience-based insights on what to watch out for and how to avoid costly mistakes.
The Most Common Concerns (Real Issues from African Job Sites)
1. Water leakage during storms—fixed repeatedly but never resolved
Africa experiences seasonal storms and long rainy periods, making water leakage a persistent issue. Many buildings suffer from seepage around windows, interior mould, or even water flowing along structural frames into interior floors, damaging finishes and equipment.
What’s worse, repairs often fail to last. The root causes are usually poor waterproof design, substandard sealants, and inadequate workmanship—simply not built to withstand African climatic conditions.
2. Glass breakage and falling panels—serious safety risks
With many high-rise buildings and prolonged exposure to strong sunlight, the risk of spontaneous glass breakage is higher. Some projects use low-quality tempered glass without heat soaking, leading to breakage within a few years.
In other cases, unitised curtain walls lack proper mechanical support and rely solely on structural sealants, which degrade over time. Falling glass from height is a major hazard and can result in serious legal liability for building owners.
3. Unclear pricing—low initial quotes, escalating final costs
The market can be highly inconsistent. Some contractors deliberately offer low quotes to secure projects, then introduce additional charges later: thicker aluminium, upgraded glass, extra sealing costs, added embedded parts. Final costs can easily double.
Even worse, some use substandard aluminium, recycled materials, or inferior sealants—issues that only become apparent after a few years, leading to deformation, leakage, and corrosion.
4. Subcontracting issues—no proper site management
Many companies act as intermediaries, subcontracting work to temporary crews. Project managers rarely visit the site, and workers’ skill levels vary greatly.
Hidden issues such as misaligned embeds, weak welding, or poor sealing can later require extensive and costly repairs. Delays are also common, and in Africa, time overruns directly translate into financial loss.
5. Unsafe renovation practices for older buildings
Many older buildings in Africa undergo facade upgrades. Some contractors fail to assess the existing structure before installation. Poor integration between old and new systems, lack of reinforcement, and inadequate waterproofing can lead to instability—especially during storms.
In addition, issues like excessive glare or shading may fail to meet updated local regulations, causing inspection failures.
6. No after-sales support—no one to call when problems arise
Once the project is completed and final payments are made, some contractors disappear. When glass breaks, sealants deteriorate, or hardware fails, clients are left to find solutions themselves—often at high cost and uncertain quality.
Given Africa’s harsh climate, long-term maintenance is essential, and lack of support can become a significant burden.
How to Avoid These Pitfalls
Based on years of experience, here are key points to remember when selecting a curtain wall contractor in Africa:
1. Choose a local, established company
Africa’s climate and regulations are unique. External or temporary companies often lack local knowledge and cannot provide reliable after-sales service.
A trustworthy company should have:
Over a decade of experience
Proper certifications (curtain wall, steel structure, etc.)
A physical office and manufacturing base
A strong project portfolio (ideally 200+ projects)
2. Ensure the team is in-house
Ask clearly: Is the construction team directly employed? Are project managers and technicians certified?
In Africa, high-rise work requires strict standards. A fully in-house team ensures quality control and accountability. Project managers should be on-site daily, monitoring progress and documenting hidden works.
3. Materials are critical—no compromises
Africa’s harsh conditions demand high-quality materials:
Aluminium: primary aluminium, adequate thickness (≥3.0mm for open sections, ≥2.5mm for closed sections)
Glass: certified tempered, laminated, or Low-E insulated glass with heat soaking to reduce breakage risk
Sealants: high-quality structural and weatherproof sealants with double sealing and pressure-equalised cavity design (water tightness ≥1500Pa)
Hardware: stainless steel, corrosion-resistant
Low-quality materials may appear acceptable initially but will fail within a few years.
4. Transparent pricing is essential
A reliable quotation should be fully itemised: materials, labour, transport, installation, taxes—everything clearly listed.
Avoid hidden costs and insist on a contract clause preventing price increases during the project.
5. Tailored design for African conditions
Professional contractors should provide:
Free site measurement and inspection
Customised design based on local climate (storms, rainfall, heat)
Consideration of energy efficiency and architectural style
For renovation projects, structural assessment is essential to ensure safety and compliance with local standards.
6. Strong after-sales support
In Africa, after-sales service is more important than initial cost. A reliable contractor should offer:
Structural and component warranties
Long-term maintenance support
Regular inspections (especially before storm seasons)
Fast response times (e.g. within 48 hours)
Choosing a curtain wall contractor in Africa is not about finding the lowest price—it’s about safety, durability, reliability, and long-term peace of mind.
Key takeaways:
Prioritise local experience and proven capability
Ensure an in-house team and certified professionals
Use only high-standard materials
Demand transparent pricing
Secure long-term after-sales support
Avoid subcontracting, substandard materials, and suspiciously low quotes.
Companies with over a decade of experience in Africa, strong local knowledge, in-house teams, quality materials, transparent pricing, and reliable after-sales service are the safest choice.
If you are planning a curtain wall project in Africa—whether for offices, factories, hotels, commercial buildings, or facade renovation—make sure you choose a partner who can deliver not just a competitive price, but a safe, durable, and well-executed solution that will stand the test of time.
