Engineered for energy efficiency, comfort and long-term performance. Windows, façades, cladding, shading and outdoor systems — coordinated as one envelope for your project.
The value is performance that lasts — designed into every system we engineer, not claimed in marketing copy.
Designed to reduce heat transfer and improve building energy performance.
High-performance envelope systems designed for quieter interiors.
Protection against rain, wind, moisture and demanding outdoor conditions.
Composite materials and integrated systems designed around long-term performance.
Durable materials and replaceable components help reduce maintenance over time.
Nine systems engineered to work together — from the window to the façade, the cladding to the roof terrace. Explore the full technical detail on the Products page.








Engineered for passive and ultra-low-energy buildings — a multi-chamber alu-wood composite profile with verified whole-window thermal performance.
Envelope systems specified for real buildings — where engineering performance meets design intent.
Residential, hospitality, education and commercial applications — in China and across international markets.
Thermal, air/water/wind, acoustic, fire and material data — with test reports your spec team can verify.
Whole-window and façade thermal data for spec decisions.
Air permeability, water tightness and wind-load resistance.
Weathering, aging and fire classification documentation.
We configure systems to your building — not the other way around.
We configure systems by building type, climate, budget and performance targets.
Parameters, details, test evidence and installation boundaries — documented.
Reference projects, showroom samples and operational data you can check.
Headquarters technical support plus local project delivery.
