Curtain walls for office buildings in Bucharest — complete guide 2026: systems, prices and design

The Bucharest office market and the demand for a modern facade

Bucharest is the most active office market in South-Eastern Europe. In 2024–2025 the modern office stock passed 4 million sqm, with 15–20 new projects a year in areas such as Floreasca–Barbu Văcărescu, Pipera, Centru-Vest and Timpuri Noi.

The de facto standard for any class A office building in Bucharest in 2026 is the aluminium and glass curtain wall — a requirement driven by corporate tenants (multinationals), by energy certification standards (BREEAM, LEED, DGNB) and by European energy efficiency rules.

Neofort BIZ works directly with property developers, architects and general contractors in Bucharest on the supply and installation of Alumil curtain wall systems. This page brings together everything you need to know before opening a project file. See also the complete aluminium joinery guide.

What makes a curtain wall suitable for offices

Unlike a residential building, an office facade has to meet technical, aesthetic and certification requirements that are far stricter, all at the same time:

Technical requirements:

• Wind resistance: class C4/B4 (pressure ≥ 2,000 Pa) for heights above 20 m
• Water tightness: class E1050 or E1200
• Air permeability: class A4
• Thermal performance: assembly Uw ≤ 1.4 W/m²K (BREEAM Very Good requirement)
• Fire resistance: minimum EI 30 at floor compartmentation

Aesthetic requirements:

• A uniform visual line across all elevations
• Compatibility with integrated shading systems (Raffstore blinds in a cassette)
• Options for reflective glass, screen printing or digital printing
• The possibility of special RAL coating or anodising

Certification requirements:

• Declaration of Performance (DoP) to EN 13830
• Thermal calculations validated to EN ISO 10077
• Wind test report to EN 12179
• BREEAM/LEED documentation on request

Alumil curtain wall systems — technical comparison

Alumil CW50 — the standard system, the most used in Bucharest

A 50 mm visible profile vertically and horizontally. The most economical and the fastest to install. Held permanently in stock in Bucharest — delivery in 3–5 days.

Technical specifications:

• Mullion depth: 50 mm
• Thermal break: 34 mm polyamide
• Assembly Uw: 1.3–1.6 W/m²K (double Low-E glazing 4+16+4)
• Assembly Uw: 1.0–1.2 W/m²K (triple Low-E glazing)
• Wind resistance: C4/B4 (2,000 Pa)
• Water tightness: E1050
• Maximum glazing: 50 mm
• Maximum panel height (without intermediate support): 4,200 mm
• Maximum panel width: 1,800 mm

Integrated shading cassette options: 80 mm Raffstore blinds and Zipscreen can be integrated into the curtain wall cassette.

Alumil CW60 — slim profile system, premium appearance

A 60 mm visible profile vertically, with a narrower design than the CW50. Preferred by architects who want fine lines on the facade.

Technical specifications:

• Mullion depth: 60 mm
• Thermal break: improved 34 mm
• Assembly Uw: 1.1–1.4 W/m²K (double Low-E glazing)
• Compatible with triple Low-E glazing for BREEAM Excellent
• Wind resistance: C4/B4

Alumil structural curtain wall — maximum aesthetics

The profile is entirely concealed. From outside only the glass and the silicone joints are visible. The most requested option for corporate headquarters, 4–5 star hotels and architecturally significant buildings.

Glass types for office facades — what the market chooses in 2026

Double-sided reflective glass — the standard for Bucharest offices. It reduces overheating in south and west facing spaces. Solar factor g = 0.20–0.35.

Double Low-E glazing (4+16+4 argon with a Low-E coating) — the BREEAM Very Good standard. Uw = 1.0–1.2 W/m²K. The most frequently specified option in new projects in Barbu Văcărescu and Floreasca.

Screen-printed glass — ceramic printing on face 2 or 4. It allows branding on the facade, tailored solar control and architectural effects.

Electrochromic glass — changes transparency on electrical command. It costs three to five times more than standard glass and is used in premium projects with a facade budget above 500 EUR/sqm.

How a curtain wall project is calculated

Step 1 — The facade study (1–3 days)

Neofort BIZ carries out the facade study together with the project architect. We define the system type (standard, semi-structural or structural), the facade module (panel width), the glass type and the integrated shading system.

Step 2 — Structural calculation (3–7 days)

Wind calculation to EN 1991-1-4, verifying the resistance of mullions and transoms against the loads specific to the site. Mandatory for the building permit.

Step 3 — Shop drawings (7–14 days)

Detailed fabrication drawings with every junction, corner detail, connection to the building structure, and penetrations for electrical services and shading systems.

Step 4 — Production (21–35 days)

CNC-cut profiles, glass ordered from Saint-Gobain or Guardian with the thermal and optical specifications set out in the project.

Step 5 — Installation (depending on the area)

• 500 sqm: 10–15 days with a team of 4 installers plus scaffolding
• 2,000 sqm: 30–45 days with 2 teams working in parallel
• 5,000+ sqm: individual planning on a monthly programme

Step 6 — Testing and handover

Water tightness test (spray) and air permeability test to EN 1027/EN 1026. Complete documentation for the handover of the works and for the BREEAM/LEED file.

Office districts in Bucharest — the projects we deliver

Frequently asked questions

What technical requirements must an office curtain wall meet in Bucharest?

An office facade has to achieve, simultaneously: wind resistance class C4/B4 (pressure ≥ 2,000 Pa) above 20 m in height, water tightness class E1050 or E1200, thermal performance Uw ≤ 1.4 W/m²K (a BREEAM Very Good requirement) and fire resistance of at least EI 30 at floor compartmentation.

Why is the curtain wall the standard for class A office buildings?

The aluminium and glass curtain wall is the de facto standard for any class A office building in Bucharest in 2026, driven by multinational corporate tenants, by BREEAM, LEED and DGNB energy certification, and by European energy efficiency rules.

Which green building certifications do Alumil curtain walls support?

Alumil curtain wall systems can meet the requirements of BREEAM, LEED and DGNB certification, with technical documentation supplied on request. A thermal performance of Uw ≤ 1.4 W/m²K corresponds to the BREEAM Very Good requirement for facades.
