Why Nail-Free Matters
PUR-Bonded doors last 10× longer than traditional nailed doors — no rust spots, no edge lifting, no moisture damage.
Traditional doors are held together with nails, staples, and generic water-based glue. The nails rust, the glue fails, and the edges lift within 2–3 years. CriLam's CriLam PUR-Bond™ technology eliminates every one of those failure points.
Traditional Door vs CriLam Nail-Free
Traditional Nailed Door
- Visible rust spots where nails meet moisture
- Edge lifting from generic water-based glue failure
- Bubbles and delamination near hinges
- Termite entry points at nail holes
- 2–3 year visible degradation
CriLam PUR-Bonded Door
- Zero nails · zero rust · sealed forever
- PUR molecular bond — 5× stronger than water-based glue
- Zero bubbles · zero edge lifting
- Termite-proof substrate · sealed entry points
- 10-year written CriLam guarantee
Feature-by-Feature Comparison
The Science Behind PUR-Bonding
Molecular Cross-Linking
PUR (Polyurethane Reactive) adhesive forms a molecular network stronger than the substrate itself.
Moisture-Curing
PUR uses ambient moisture to cure — meaning humidity strengthens the bond over time, not weakens it.
Zero Mechanical Fasteners
No nails, no staples, no rust vectors. The bond IS the construction — invisible and permanent.
Did You Know?
Only a handful of factories in India can operate a PUR lamination line — it requires precise temperature, humidity, and pressure control. CriLam operates one of the largest PUR-bonding facilities in the region, right here in Kanpur, UP.
