| Hinged Units | Side-opening windows | Opens inward like a door; ideal for fire gets away or clear views. |
| Lift-out Units | Smaller windows/ Static views | Lightweight frames that can be physically raised out for cleaning. |

Step 3: Detailed Quotation
Quotes ought to be detailed. An unclear "lump amount" rate is a red flag. The file should clearly specify the glass type, frame surface (normally powder-coated aluminum), and the addition of VAT and setup labor.
