FAQ | 5D Profile

Q: Why do some cheap resin tiles puncture or shatter during hail storms (the "Starry Sky" effect), and how does your product prevent this?

Cheap tiles use a high percentage of brittle recycled PVC and excessive calcium carbonate (filler) to cut costs, making them highly brittle and prone to shattering under kinetic impacts. Our Alfa and above tiles are manufactured using 100% virgin PVC resin combined with specialized impact modifiers in the core layer. This creates a flexible, high-toughness matrix that absorbs mechanical shock from severe hail storms without a single puncture.

Q: Why is it mandatory to use "thermal expansion fasteners" (over-drilling) during installation?

Polymers naturally expand with heat and contract with cold. ASA-PVC sheets have a distinct thermal expansion coefficient. During installation, you must pre-drill holes that are 2mm–3mm larger than the screw shank (e.g., a 9mm hole for a 6mm screw). This over-drilling leaves critical horizontal clearance for the tile to "breathe" during intense midday heat. Skipping this step will trap the tile, leading to structural warping, buckling, and severe cracking around the screws.

Q: Are your roofing sheets noisy during heavy tropical rainstorms?

No. Unlike traditional corrugated iron (zinc) sheets which amplify the sound of rain like a drum, synthetic resin tiles feature a 3-layer composite structure with excellent acoustic insulation properties. It can reduce rain impact noise by up to 30 decibels, ensuring a much quieter and more comfortable indoor environment during heavy downpours.

5 Core Factors Affecting Resin Tile Lifespan

Raw Material Quality (Virgin vs. Recycled)
Virgin Resin: Offers stable molecular structures and excellent UV resistance.
Recycled Resin: Makes tiles brittle, leading to cracking or warping within 2-3 years.
ASA Coating Layer Thickness
Thickness ≥ 0.15mm: Effectively resists UV rays, preventing severe fading for 15+ years.
Thickness < 0.10mm: Wears off within 1-2 years, exposing the PVC base to fast degradation.
Total Tile Thickness
Standard (2.5mm - 3.0mm): Provides high structural strength to withstand hail and heavy loads.
Thin Options (≤ 2.3mm): Compromises overall durability and lifespan; always measure thickness with calipers.
Installation Quality & Fasteners
Purlin Spacing: Incorrect spacing causes uneven weight distribution, warping, or cracking.
Waterproof Accessories: Standard screws rust easily; using ASA waterproof caps prevents leaks at screw holes.
Environmental Exposure
Corrosive Elements: High heat, acid rain, and chemical fumes from livestock or factories speed up aging.
Roof Pitch: Low slopes cause water accumulation, which accelerates edge rot and leaking.
