Engineered to deliver exceptional acoustic insulation, wind pressure resistance, and airtight integrity for regional Brazilian real estate developments.
The Brazilian architectural landscape is transitioning towards highly efficient, durable, and sustainable solutions. Real estate development sectors in major urban hubs like São Paulo, Rio de Janeiro, and Belo Horizonte face distinct challenges: severe acoustic pollution, microclimatic temperature variations, and high UV radiation. Standard sliding windows fail to meet these complex performance parameters.
Architects and structural engineers now mandate compliance with the strict building code guidelines established by ABNT NBR 10821 (which regulates structural stability, water tightness, and air infiltration for windows) and ABNT NBR 15575 (setting performance metrics for residential installations). Furthermore, coastal developments in regions like Santa Catarina or Nordeste demand high wind load thresholds and exceptional corrosion resistance due to aggressive saline environments.
By leveraging advanced thermal-break profiles and multi-point secure locking systems, our solutions enable developers to secure high ratings on the Procel Edifica energy certification scale, cutting HVAC loads significantly in tropical environments.
Aligning international standards with localization vectors to ensure seamless global-local execution.
Integrating polyamide insulation bars (PA66GF25) to isolate external thermal pathways. This decreases heat gain inside the structure, helping developments optimize cooling costs under solar stress.
Structural profiles tested against extreme wind pressures of up to 4500 Pa (equivalent to Category 5 hurricanes), satisfying high-rise building regulations in urban locations.
Using multi-layer laminated structural glazing with PVB/SGP interlayers and dense dual-density EPDM gaskets, creating noise reduction profiles that decrease noise by up to 45 decibels.

Select from our tested series of high-insulation sliding windows, lifting structures, and minimalist patio entries.
Seamless customs coordination, structural drawing integration, and localized delivery timelines.
We manage direct ocean freight services to major Brazilian ports, including the Port of Santos (SP), Port of Paranaguá (PR), and Port of Itajaí (SC). All shipments feature multi-layered protective wooden crating to prevent movement and humidity damage during transit.
We provide full documentation compliant with Brazilian import regulations, supplying accurate NCM classification codes (Nomenclatura Comum do Mercosul), detailed commercial invoices, and origin certificates to facilitate straightforward customs clearance through Siscomex.
Our engineering team works closely with local Brazilian development firms, supplying detailed AutoCAD and Revit BIM profiles. This allows seamless integration into structural design files, verifying load compliance before shipping.
Important details for builders, architects, and importers selecting sliding window manufacturers for Brazil.
Yes. All our exported window systems undergo testing for air infiltration, water pressure resistance, and wind load deflection. We provide complete testing documentation matching the wind load zones of Brazil, including Zone 5 (covering high-wind southern regions and coastal high-rises).
We apply high-grade surface coatings, including architectural-grade PVDF and electrostatically sprayed powders from reliable international brands. These coatings are tested under ASTM B117 salt spray guidelines for over 3,000 hours, preventing pitting and bubbling in coastal locations like Balneário Camboriú and Rio de Janeiro.
For container-load production orders, manufacturing takes between 30 and 45 days, depending on customization requirements. Sea transit from our loading ports in China to the Port of Santos or Paranaguá ranges from 35 to 45 days. We coordinate all logistics steps to ensure timely delivery schedules.
Yes. Our premium thermal break designs utilize reinforced polyamide insulation strips. This structure separates external heat from interior spaces, improving overall HVAC efficiency and matching thermal performance goals for sustainable buildings seeking AQUA-HQE or LEED certification in Brazil.
Absolutely. Our Industry 4.0 production lines are configured for high-end customization. We can match any RAL color specification, run customized extrusion sizes, and pre-integrate specialized glass configurations, including double-glazed low-E and laminated acoustic units.
