Architectural Aluminum Sliding Doors: Panorama Glazing & Thermal Efficiency
Contemporary residential architecture relies heavily on aluminum joinery to erase boundaries between indoor living spaces and outdoor terraces.
1. Lift-and-Slide vs. In-Line Sliding Systems
- Lift-and-Slide (Levant-Coulissant): Designed for heavy triple-glazed panels weighing up to 400 kg. Turning the ergonomic handle mechanically raises the sash onto micro-rollers, gliding with zero effort.
- In-Line Multi-Track Systems: Pocket door options (galandage) slide entirely into wall cavities, creating 100% unobstructed openings.
2. Thermal Break Engineering (RPT)
Modern aluminum profiles incorporate polyamide insulating ribs reinforced with fiberglass, preventing condensation and exceeding RT2020/RE2020 standards with overall Uw values below 1.3 W/m²K.
3. Coastal Durability: Qualicoat & Qualimarine
For beachfront or seaside properties, certified surface treatments (Qualimarine & Seaside Qualanod) ensure powder-coated finishes resist marine salt mist, corrosion, and tropical UV radiation.
