Project Overview
At Zhongbo Glass, we are honored to be entrusted with the glazing for one of the most prestigious diplomatic construction projects currently underway in China: the new Embassy of the United Arab Emirates in Beijing. Embassies demand the very highest standards of security, energy performance, and architectural elegance. This landmark building, now rising in the heart of the capital, required a glass facade that combines absolute optical precision with advanced solar control — and we are proud to be the exclusive manufacturer delivering that vision.
The specification called for an exceptionally sophisticated triple-laminated, heat-strengthened insulating glass unit (IGU) featuring a state-of-the-art double silver Low‑E coating. Every glass ply is heat-strengthened (semi-tempered) to avoid the optical distortion of fully tempered glass, while the triple SGP lamination on both the outer and inner panels provides unparalleled safety and structural redundancy. Panel sizes reach an imposing 6,850mm in length, making this one of the largest heat-strengthened triple-laminate IGUs ever produced for an embassy. At Zhongbo Glass, we are currently manufacturing and delivering these panels, proving that our capabilities are not just historical — they are happening right now.
Glass Configuration — A Masterpiece of Optical and Thermal Engineering
The embassy’s facade required a glass make-up that provides the highest possible optical quality, robust security, and exceptional energy performance in Beijing’s continental climate. We engineered the following symmetrical, triple-laminated IGU:
(HS12mm Ultra-Clear + 2.28mm SentryGlas® Plus (SGP) + HS12mm Ultra-Clear + 2.28mm SGP + HS12mm Ultra-Clear Double Silver Low‑E) / 16mm Air Cavity / (HS12mm Ultra-Clear + 2.28mm SGP + HS12mm Ultra-Clear + 2.28mm SGP + HS12mm Ultra-Clear)
Every component is selected for a specific diplomatic-grade function:
-
All Heat-Strengthened (HS) Glass: Every 12mm ply is heat-strengthened, with a surface compression between 24 and 52 MPa. This process imparts twice the strength of annealed glass while virtually eliminating roller-wave distortion and the risk of spontaneous nickel sulfide breakage. For an embassy, where the facade must present a flawless, undistorted reflection befitting its diplomatic stature, this optical perfection is non-negotiable.
-
Triple SGP Lamination on Both Sides: The outer panel consists of three 12mm ultra-clear HS plies bonded with two 2.28mm SGP interlayers. The inner panel is identical but without the coating. SGP’s high stiffness and five times the tear strength of PVB provide exceptional post-breakage integrity and forced-entry resistance, critical for an embassy’s security requirements.
-
Double Silver Low‑E Coating: The #5 surface (inner face of the outer triple laminate) carries a high-performance double silver Low‑E coating. Dual silver layers achieve a superior balance of high visible light transmission and ultra-low solar heat gain, along with excellent thermal insulation. This reduces the embassy’s energy demand while maintaining bright, naturally lit interiors.
-
16mm Air Cavity: The sealed air space between the two massive laminates provides an effective thermal break, further enhancing the U‑value and acoustic insulation.
-
All Ultra-Clear Glass: Premium low-iron glass is used throughout, eliminating the greenish tint of standard float glass and providing true color rendering for the embassy’s interiors and the building’s external appearance.
Maximum Glass Size: 2,985mm × 6,850mm — Monumental Precision
The maximum glass panel size is 2,985mm in width by 6,850mm in height. Each finished IGU covers over 20 square meters and, with a total glass thickness of 72mm (six plies of 12mm) plus four SGP interlayers and cavity, weighs several tonnes. Producing a heat-strengthened triple-laminate on both sides of the IGU at this scale — with perfect flatness, a delicate double silver Low‑E coating, and a hermetically sealed cavity — is a manufacturing achievement of the highest order. At Zhongbo Glass, panels of this dimension and complexity are currently being produced and shipped to Beijing, demonstrating our active leadership in super-jumbo, optically perfect architectural glass.
Overcoming the Challenges — Zhongbo Glass’s Engineering Excellence
1. Flawless Heat-Strengthening at 6.85 Meters
Heat-strengthening 12mm ultra-clear glass at lengths approaching 7 meters requires extraordinary furnace uniformity. Our super-jumbo flat tempering furnace operates with proprietary HS profiles for low-iron glass, achieving consistent surface compression (24-52 MPa) across every millimeter while maintaining flatness that meets the tightest architectural standards. All six plies per IGU are matched to ensure perfect alignment and optical consistency throughout the triple laminate.
2. Triple SGP Lamination on Both IGU Panels
Laminating three 12mm heat-strengthened plies with two stiff 2.28mm SGP interlayers — and then repeating this for the inner panel — is a demanding process. SGP’s high modulus requires extended de-airing and precise autoclave control. Our process includes:
-
Class 1 cleanroom layup to eliminate any particle contamination.
-
Vacuum bag de-airing with extended cycles tailored for thick, stiff SGP stacks.
-
Custom autoclave cycles in our large-format autoclave, ensuring bubble-free, edge-to-edge adhesion on both the outer and inner triple laminates. The result is a transparent panel with outstanding structural integrity and clarity.
3. Protecting the Double Silver Low‑E Coating
The outer triple laminate incorporates the double silver Low‑E coating on an interior surface. This coating is more sensitive to handling and lamination than standard single-silver Low‑E. We process all coated glass in a climate-controlled cleanroom with automated edge deletion. The lamination process is carefully managed to preserve coating emissivity and visual appearance, ensuring the embassy gets the full energy performance and color neutrality specified.
4. Insulating Glass Assembly of Two Heavy Triple Laminates
Coupling two triple-laminated panels, each 36mm thick and weighing over a tonne, into a perfectly sealed IGU with a 16mm cavity demands specialized equipment. We used synchronized vacuum lifters, laser alignment, and robotic dual-seal application to create a uniform cavity and a hermetic perimeter seal. Every unit is tested for dew point and seal integrity, guaranteeing long-term thermal and optical performance.
5. Logistics: Delivering Sensitive, Heavy Glass to Beijing
Transporting finished panels of such weight and sensitivity from our factory to an active diplomatic construction site in Beijing requires a customized logistics plan. We designed reinforced transport stillages with full-contact support and vibration dampening. Air-ride trailers and carefully coordinated deliveries ensure that each panel arrives in perfect condition, protected from edge damage and stress.
