Factory-fabricated, pressure-equalized prefabricated glass facades engineered for high-rise towers, seismic resistance, and extreme wind loads worldwide.
As commercial architecture demands faster construction cycles, stricter thermal compliance (LEED / BREEAM), and superior weather envelope seals, the high-rise sector is rapidly replacing field-assembled stick curtain walls with prefabricated Unitized Glass Curtain Wall systems.
A Unitized Glass Curtain Wall consists of large factory-assembled and glazed facade panels that are hoisted onto the building's structural concrete slab using floor-by-floor crane systems. Unlike traditional stick curtain walls—where mullions, transoms, and glass units are installed piece by piece on-site under unpredictable weather conditions—unitized modules are manufactured inside controlled cleanroom environments.
At Doorreme Aluminum Industry Co., Ltd., our Foshan manufacturing complex utilizes CNC machining centers and automated structural silicone glazing lines to achieve micro-tolerance interlocking split mullion joints. This controlled assembly guarantees optimal adhesion of structural sealants (Dow Corning / Tremco), eliminates water infiltration risks, and reduces total exterior envelope installation time by up to 60%.

Staying ahead in commercial real estate requires anticipating shifting building codes, environmental benchmarks, and technological advancements in building envelopes.
Future-ready facades are transforming from passive barriers into active power generators. Modern unitized panels increasingly integrate Building-Integrated Photovoltaics (BIPV) in spandrel zones and electrochromic smart glass that automatically tints based on solar radiation, reducing building HVAC energy consumption by up to 35%.
Global procurement standards now mandate verified Environmental Product Declarations (EPD). Doorreme Aluminum Industry Co., Ltd. leads this shift by sourcing hydro-powered, low-carbon aluminum billets and post-consumer recycled alloys, significantly reducing embodied carbon without sacrificing tensile yield strength.
With urban site footprints becoming tighter and crane rental costs rising, developers demand fully integrated unitized units pre-fitted with motorized parallel-opening windows, automated sunshades, architectural louvers, and interior fire-stop insulation before shipment to the site.
Discover how cutting-edge material science and structural engineering enhance facade reliability, thermal resistance, and acoustic isolation.
Water leakage is the single greatest cause of facade failure in coastal and high-wind environments. Advanced Unitized Glass Curtain Wall designs utilize the Pressure Equalization Principle. The joint cavity between male and female split mullions is engineered with continuous EPDM (Ethylene Propylene Diene Monomer) gasket lines, dividing the frame into an unsealed outer rain-screen zone and an airtight inner pressure chamber. Equalizing air pressure prevents wind-driven rain from passing through seal gaps.
To prevent thermal bridging across conductive aluminum frames, Doorreme integrates high-grade PA66 GF25 (25% glass-fiber reinforced polyamide) thermal break strips. Combined with double or triple insulated glass units (IGUs) featuring low-emissivity coatings (Double-Silver / Triple-Silver Low-E), argon gas filling, and warm-edge composite spacers, our unitized systems achieve overall U-factors as low as 0.9 W/(m²·K), meeting net-zero building energy targets worldwide.
High-rise structures experience continuous dynamic movement caused by thermal expansion, wind sway, and seismic shear forces. Unitized panels are hung via three-dimensional adjustable cast-in anchor brackets, allowing independent movement in horizontal (±25mm), vertical (±15mm), and inter-story displacement directions without stressing the structural glass or compromising seal integrity.
