UV Radiation in Kenya: Why "Co-Extrusion" is Non-Negotiable for Your Roof
Kenya’s intense sunlight, especially in Nairobi, Mombasa, and Malindi, exposes roofs to high levels of UV radiation, which can degrade standard roofing materials, reduce lifespan, and increase maintenance costs. Using co-extruded roofing in Kenya ensures your roof is UV-protected, durable, and long-lasting, making it an essential investment for homes, warehouses, and commercial buildings.
What Is Co-Extrusion Technology?
Co-extrusion roofing in Kenya is a process where a UV-protective layer is permanently fused to polycarbonate or acrylic sheets. This creates long-lasting UV resistance, preventing yellowing and cracking under strong Kenyan sunlight.
Co-extrusion adds a permanent protective layer during manufacturing:
-
Shields roofing sheets from UV degradation
-
Preserves transparency and structural integrity
-
Reduces long-term replacement and maintenance costs
BHD Products Using Co-Extrusion:

Solid Polycarbonate Sheets – UV-stabilized for high-intensity Kenyan sunlight
-
Egyptian Hollow Polycarbonate Sheets – insulated and UV-protected
-
Alucobond Sheets – premium UV-reflective panels
Why UV Protection Is Critical in Kenya
Co-extruded roofing in Kenya is essential because the country experiences some of the highest UV indexes in Africa. Without UV protection, roofs can yellow, crack, and lose strength within a few years.
-
Coastal areas (Mombasa, Malindi): High UV + humidity → non-protected sheets degrade in 3–5 years
-
Nairobi & Nakuru: Altitude sun exposure → potential brittleness and discoloration
-
Warehouses and greenhouses benefit from co-extruded sheets to maintain light transmission and durability

Solid vs. Hollow Co-Extruded Sheets
For co-extruded roofing in Kenya, solid sheets offer maximum impact resistance and UV protection, while hollow sheets provide insulation and lighter weight. Both extend roof lifespan under Kenyan sun conditions.
| Sheet Type | UV Protection | Impact Resistance | Insulation | KEBS Standard |
|---|---|---|---|---|
| Solid Polycarbonate | Excellent | Very High | Low | KS 02-17 |
| Hollow Polycarbonate | Excellent | High | Moderate | KS 02-17 |
| Alucobond Sheets | Excellent | Very High | Moderate | KS 02-17 |
Installation Tips for Co-Extruded Roofing in Kenya
Proper installation of co-extruded roofing in Kenya maximizes UV protection and durability. Ensuring alignment, sealing, and support structures is key to long-lasting performance.
-
Orient sheets so the UV layer faces sunlight
-
Use EPDM gaskets or silicone sealants to prevent water ingress
-
Ensure proper roof framing, especially for hollow sheets

Cost vs. Long-Term Savings
Investing in co-extruded roofing in Kenya may have a higher upfront cost, but it saves money on replacements, repairs, and damage from UV exposure, making it highly cost-effective.
-
Solid sheets: higher initial cost, maximum durability, strong impact resistance
-
Hollow sheets: moderate cost, insulation benefits, still UV-protected
-
Long-term ROI can exceed 5–7 years of maintenance savings
