Doors, windows & facades
Part of the Construction & Public Works sector
Doors, windows and facades are the building envelope products that close a structure in — letting in light while keeping out weather, noise and heat loss. This hub explains the main types and how to find and compare verified suppliers on Digibition.

Overview
This category covers the products that form the openings and outer skin of a building: windows, external and internal doors, curtain walls and facade cladding systems. They are made from frames of aluminium, PVC, timber or steel, combined with glazing, panels, seals and the ironmongery that lets them open, close and lock.
Beyond appearance, these products are rated for performance — thermal insulation, air and water tightness, acoustic reduction, security and, for larger facades, wind and structural loads. Buyers include contractors, developers, fabricators and renovation firms specifying for new build or refurbishment.
On Digibition, manufacturers and suppliers of windows, doors and facade systems publish verified profiles, so professional buyers can discover and compare them by specialization and country.
What to check when sourcing
When you source doors, windows and facades, match the product to the performance the project requires. Confirm the frame material and system, the glazing specification, and the rated values for thermal insulation, air and water tightness, acoustics and security — against the standards and marks your market expects, provided here as examples rather than requirements.
For facades and larger glazed areas, structural and wind-load performance and the fixing system matter as much as the panels themselves. Weigh minimum order quantities, lead times, how units are packed and protected for transport, and whether the supplier provides fabrication drawings or installation support.
Use the directory to shortlist suppliers by specialization and country, then contact several and compare their responses before you commit.
