What Are the Key Differences Between PVC and Composite Resin Balustrades?

Feature----------Value Fencing® PVC Balustrades----vc----Composite Resin

Material Composition	Virgin uPVC (ASTM-certified)	Resin-bound composite & fillers
Strength & Impact Resistance	Passed Pendulum Impact Test (Ilala Estate 2015)	Failed Pendulum Impact Test repeatedly
Installation Method	Posts mounted with dual rebar rods (150mm deep) epoxied into substructure; filled with 25MPA 42.5s concrete	Surface-mounted or with a single shallow rebar (
Durability	UV-stabilized; won't rot, rust, blister, or fade	Resin components may crack, fade, or delaminate over time, especially in harsh environments
Lifespan	20+ years with structural integrity maintained	Shorter lifespan; frequent profile separation and structural loosening reported in coastal applications
Maintenance	No sanding, painting, or sealing needed	Requires periodic resealing, painting, and realignment due to material fatigue
Appearance Over Time	Remains clean, white, and glossy with minimal effort	Susceptible to yellowing, dullness, and staining without regular upkeep
Coastal Suitability	Ideal - no corrosion, even with salt spray	Vulnerable to salt exposure and UV degradation
Safety & Code Compliance	Structurally reinforced for high loads and wind exposure	Often fails load-bearing and impact standards under real-world conditions
Environmental Resistance	Termite, water, and weatherproof	Can absorb moisture, leading to expansion, warping, or joint failure

Real-World Case: Ilala Views Development, Umhlanga

❌ Composite Resin balustrades cracked, dislodged, and failed safety checks
✅ Value Fencing® PVC passed every test, staying intact and compliant

Outcome: All balustrades at Ilala Views were replaced with PVC from Value Fencing®.

Why Do Composite Resin Balustrades Often Fail?

Typically surface-mounted or installed with a single shallow rebar (
Resin-based material is brittle, especially in UV and salt-prone regions
Separation of profiles occurs frequently over time, creating safety and aesthetic concerns
Lacks internal reinforcement or structural fillers like concrete
