The Definitive Guide to Amari uPVC Roofing: Benefits, Uses & Why Castalia Delivers

Introduction: What Is uPVC Roofing and Why It Matters

Unplasticized Polyvinyl Chloride (uPVC) roofing—commonly sold as twin-wall corrugated roofing sheets—is a lightweight, durable, and thermally efficient alternative to metal, fiber, or ceramic roofing. Thanks to its robust performance in tropical climates like Singapore, uPVC is ideal for mitigating heat, reducing noise, and resisting wind and corrosion. With Castalia International distributing Amari uPVC roofing, clients in Singapore enjoy world-class standards backed by innovation and a 10-year warranty opportunity.

1. Why Amari uPVC Roofing Stands Out

1.1 Exceptional Heat Insulation & Comfort

Amari panels reflect up to 71% of solar heat, keeping indoor and covered areas significantly cooler even under intense sun.
Its triple-layer design includes an ASA top coat with UV resistance, reducing heat transfer while allowing soft natural daylight into covered spaces.

1.2 Robust Corrosion & Chemical Resistance

Engineered for industrial and coastal settings, Amari roofing resists acids, alkalis, salt spray, and chemical vapors, ensuring long-term stability.

1.3 Fire Safety & Durability

Utilizing fire rating B1 (non‑combustible class), Amari offers top-level safety with durable construction designed to last over a decade.

1.4 Lightweight & Eco-Friendly Performance

Amari panels weigh 3× less than metal or composite roofing, reducing structural demand and installation costs. They are also fully recyclable, aligning with eco-conscious building standards.

1.5 Fast Installation & Sound Insulation

Installation is quick and efficient with self-drilling screws, ridge caps, and seal pack accessories. Sound reduction of up to 15 dB makes them ideal in rainy Singapore settings.
Installation slope of just 15° and overlapping design enable flexibility in roof design and structure.

5. Real-Life Impact: Suggested Use Cases

Case Study 1: Homeowners in Singapore

Installing translucent Amari panels for a patio extension reduces glare and solar gain. The UV coating ensures the shaded area remains cool and clean, ideal for outdoor gatherings or play areas. Natural daylight brightens the space without compromising comfort.

Case Study 2: SMEs & Retail Establishments

Companies using Amari roofing for delivery bay covers or outdoor stock areas benefit from less corrosion risk, noise reduction during rains, and easier maintenance—boosting durability and lowering lifecycle costs.

Case Study 3: Institutions & Clinics

Schools and clinics can install covered walkways with durable, cost-effective Amari panels. With their sound-dampening and light-transmitting features, these walkways are safer, cooler, and easier to maintain.

6. Installation Best Practices

Planning & Design

• Define roof dimensions, pitch (minimum 15°), overlap zones, and desired colour/transparency.
• Select slope to reduce runoff back-up and buildup.

Structure & Fastening

• Use compatible metal or timber sub-frame rated for panel weight.
• Utilize self-drilling screws with rubber seals for waterproofing.
• Overlap panels by 1–2 corrugations as recommended for wind tightness.

Ventilation & Water Management

• Install ridge caps, eve flash, and web closures to prevent water ingress.
• Provide adequate ventilation at roof tips to avoid heat and condensation.

Cleaning & Maintenance Tips

• Periodic rinsing with a hose keeps the surface clean.
• Inspect seal caps and fasteners yearly and replace if worn.
• With correct installation and care, Amari roofing exceeds 15–20 years’ service life.

7. Sustainability & Safety Credentials

Environmentally Responsible

• Amari sheets are 100% recyclable and free from asbestos, lead, or harmful plasticisers.

Energy Efficiency

• Reflective surface reduces cooling load, supporting lower energy use and reduced CO₂ emissions.

Long-term Durability

• Resistance to UV, fade, and degradation extends usable lifespan and minimizes waste.
