What Architects Need in a Window Schedule
A coordinated schedule should capture opening types, dimensions, performance, finishes, glass and hardware.
Read articleHow should windows and doors be specified for European projects?
European window and door specification is a whole-opening process: climate, orientation, declared product performance, glazing, hardware, installation interfaces and destination-country documentation should be coordinated together rather than selected as isolated components.
| Project context | Typical exposure | Specification priorities |
|---|---|---|
| Nordic and cold climates | Long heating seasons and low external temperatures | Whole-window Uw, airtightness, thermal bridges and suitable double or triple glazing |
| Atlantic and exposed regions | Wind-driven rain, repeated wetting and strong weather fronts | Water tightness, wind resistance, drainage, seals and installation interfaces |
| Mediterranean climates | High solar exposure and summer overheating risk | Solar-control glazing, shading coordination, ventilation strategy and durable finishes |
| Coastal locations | Salt-laden air, wind and moisture | Finish selection, corrosion-resistant hardware, maintenance access and weather seals |
What information is needed to specify windows for a European project?
Start with opening dimensions, opening type, whole-window Uw target, wind and water exposure, acoustic goals, glazing safety, finish, hardware, installation interface and the documentation required in the destination country.
Should every European project use triple glazing?
No. Triple glazing can improve thermal and acoustic performance, but glass weight, solar gain, frame capacity, climate, orientation, budget and the project energy model should be reviewed together before selecting the glazing build-up.
What does CE marking communicate for construction products?
For products within the applicable Construction Products Regulation route, CE marking links the product to declared performance assessed using a harmonised technical specification or European Technical Assessment. Project designers must still specify performance appropriate to the intended use.
European regulatory context: Energy Performance of Buildings Directive · Construction Products Regulation. Final project requirements remain subject to the applicable national rules, intended use and project specification.
