Sliding door specification case
Thermal Break Aluminum Sliding Door with Laminated Low-E Glass
A custom sliding door quotation case focused on insulation, safety glass, large opening size, and export-ready specification.
Project requirement
The buyer compared two-track and three-track sliding door options for a large opening. The requirement included thermal break aluminum, laminated insulated Low-E glass, argon filling, professional hardware, custom powder coating, and EPDM sealing.
The main value of the case is specification clarity. Instead of quoting only a general sliding door, the quotation needs to define profile system, glass build-up, opening style, size, color, hardware, and packaging.
