Why Plastic Shuttering Boards Outperform Plywood in Modern Construction
Timber-based plywood absorbs 8–12% moisture, warps within 3–5 uses, and requires constant replacement and secondary plastering rework. PAC® Plastic Shuttering Boards achieve zero water absorption, 40–60+ reuse cycles, and NABL-certified structural durability (22.0 N/mm² compressive strength), eliminating hidden costs and project delays while delivering 40% buyback credit on retired inventory.
Zero Water Absorption: The Waterproof Advantage
Conventional plywood swells when exposed to moisture, creating formwork movement and concrete surface defects. PAC® Shuttering Boards maintain moisture content of only 0.33–0.64% even after infinite submersion, preventing delamination, warping, or internal rot. This eliminates the hidden cost of secondary plastering corrections and ensures consistent concrete finish quality across every pour.
| Property | PAC® Plastic Shuttering | Timber Plywood |
|---|---|---|
| Water Absorption | 0% (Zero Swelling) | 8–12% (Warping) |
| Moisture Content | 0.33–0.64% | 10–15% |
| Submersion Durability | Infinite (No Delamination) | 2–3 soaks before failure |
| Reuse Cycles | 40–60+ | 3–5 |
| Compressive Strength | 22.0 N/mm² | 18–20 N/mm² |
| Density | 1135 kg/m³ | 600–700 kg/m³ |
NABL-Certified Structural Performance
PAC® boards are tested by NABL-accredited laboratories (Choksi Laboratories, STEDRANT Technoclinic) and deliver 22.0 N/mm² compressive strength with 1135 kg/m³ density. This superior density prevents structural cracking under repetitive load cycles. Tested nail and screw holding power reaches 2,214–2,460 N, matching timber workability while ensuring zero finish defects during formwork extraction. Heat dimensional stability of 0.07% eliminates expansion/contraction variability across seasonal changes.
| Technical Specification | Certified Value | Test Standard |
|---|---|---|
| Compressive Strength | 22.0 N/mm² | IS 1734 (Part 1-20) |
| Density | 1135 kg/m³ | IS 1734 (Part 1)-1983 |
| Tensile Strength | 11.30–11.89 N/mm² | IS 1734 (Part 9)-1983 |
| Nail Holding Power | 2,214–2,460 N | IS 1734 (Part 19)-1983 |
| Heat Stability | 0.07% | ASTM D 204 |
Workability Parity: Nail, Cut, Screw Like Timber
PAC® boards feature reinforced XLP fiber and metal dust composite that enables identical workability to plywood—nail extraction, cutting with conventional saws, and screw fastening all perform flawlessly. The higher density prevents internal cracking during repeated fastener insertion/removal, ensuring boards maintain structural integrity across 40–60+ use cycles without delamination or surface splintering that plywood exhibits by cycle 3–4.
Infinite Reuse Lifecycle: The ROI Angle
Standard White (12mm, ₹80/sq. ft.): Delivers 30–40 use cycles before scrap. After cycle completion, boards retain 40% scrap value, credited against new purchases at ₹80/sq. ft., reducing effective acquisition cost to ₹48/sq. ft. per new round. A single PAC® board replaces 10–15 timber sheets over its lifetime, netting savings of ₹1,200–₹1,800 per board.
Premium Black (12mm, ₹90/sq. ft.): Engineered for high-rise and heavy RCC (bridges, dams, hydro projects) with 60+ use cycles. Scrap-adjusted cost drops to ₹54/sq. ft. per replacement cycle. Ideal for infrastructure projects where formwork cycles 100+ times.
Heavy Column Formwork (18mm, ₹125/sq. ft.): Purpose-built for 6ft×6ft columns and deep beams, replacing costly steel plates. Infinite reusability eliminates capital equipment costs entirely.
Superior to Timber: Why Contractors Switch
- Zero Secondary Plastering: Consistent concrete finish eliminates rework labor and material cost.
- 40+ Reuse Guarantee: Single PAC® board replaces 10–15 timber sheets; timber degrades by cycle 5.
- Infinite Submersion: Works in wet weather, waterlogged sites, and underwater formwork without swelling or delamination.
- 40% Buyback Credit: Old boards retain residual value; timber is landfill waste.
- Workability Parity: Nail, cut, screw identically—zero skill retraining required.
- Prevents Structural Cracking: 1135 kg/m³ density and 22.0 N/mm² strength absorb repetitive load without internal fracture.
