CPV Code 4541, Glazing
What does CPV code 4541 cover?
CPV code 4541 (Glazing) covers all glazing and window works in building construction. This includes window installation (timber, aluminium, PVC, timber-aluminium composites), glass facade construction (mullion-transom systems, structural glazing, ventilated glass facades), fire-resistant glazing, sound insulation glazing, glass roofs, canopies and glass partitions.
Increasingly, technically demanding glazing plays a role: triple thermal insulation glazing with solar control coatings, electrochromic glass, walkable glazing and fall-protection glazing.
Who uses this CPV code?
Glazing works are tendered in virtually every building project. Key segments include schools (large glazing areas for natural daylight), administrative buildings (representative glass facades), hospitals (fire-resistant glazing), cultural buildings (architecturally demanding glazing) and sports facilities.
Bidders include glazing firms, window and facade construction companies, metal construction firms with facade divisions, and specialised facade engineers with in-house production.
How does Patterno help?
Patterno HIT filters glazing tenders by project type, region and complexity level. The AI distinguishes between simple window works, demanding facade glazing and special constructions, ensuring each company only receives suitable tenders.
Patterno BID supports calculation of glazing specifications, enabling quick matching of technical requirements, glass build-up, U-values, sound insulation classes, fire protection requirements, with the product portfolio.
Energy efficiency requirements
Rising requirements of the Building Energy Act (GEG) for thermal performance of windows and facades drive demand for high-performance glazing systems. Triple glazing with U-values below 0.8 W/(m²K) is now standard in new construction.
