Why Two Quotes Are 30% Apart for 'the Same System'

The most common reasons curtain wall quotes vary significantly:

• 1.Glass spec: clear 6mm vs DGU Low-E is a ₹150-200/sq ft material difference.
• 2.Silicone brand: generic vs Dow Corning 795 is ₹15-25/sq ft — false economy.
• 3.Profile weight: cheaper quotes use 1.4mm wall aluminium instead of 1.8-2.0mm.
• 4.Structural calculations skipped — the single most dangerous shortcut.
• 5.Post-installation testing skipped: water hose test and anchor pull-out tests cost ₹10-20/sq ft.
