Aluminum Window & Door Air Tightness Essentials Air tightness in aluminum windows and doors prevents energy loss (up to 40% HVAC savings) and blocks dust/noise. AS2047 standards mandate rigorous testing: 75Pa/150Pa pressure tests (AC rooms: ± pressure; others: + pressure only) Material tiers: Wood (weakest) < standard aluminum < thermal break systems like Rolansini’s precision-engineered profiles. Key factors: 1️⃣ Installation: Frame alignment + dual sealing (foam + cement + silicone) 2️⃣ Seals: Rolansini’s railway-grade EPDM strips resist aging. Balancing seasons: Winter insulation (blocks cold air) vs. summer natural ventilation (lower screens).

System Aluminum Window & Door Essentials True aluminum window and door systems integrate energy efficiency, weatherproofing, noise reduction, and thermal insulation via standardized design, high-insulation profiles (5x better than standard), and precision manufacturing. Rolansini’s systems excel with multi-chamber thermal-break structures, German TECHNOFORM insulation strips, aerospace-grade aluminum (6063-T5), and global hardware partners (SIEGENIA/HOPPE). Each unit undergoes laser CNC machining (±0.2mm) and stress-tests for EU-compliant durability. Prioritize systemic performance—not just visible components.

Solving Winter Condensation on Aluminum Window & Door Systems Condensation forms on aluminum window and door surfaces when warm indoor humidity meets cold glass/frames below dew point. North-facing units (kitchens/bathrooms) suffer most. Myth: Insulated glass flaws cause it. Reality: Standard double-pane (air-filled) vs. costly vacuum glass (condensation-proof). Why sealed thermal-break aluminum windows condense more? Superior insulation traps humidity vs. drafty PVC’s airflow. Fix low-cost: Ventilate 15 mins/day. High-tech: Vacuum glass (blocks -30°C frost). Check fog location: Inner layer: Faulty seals → demand replacement. Outer drips: Natural in humidity＞40% + large temp gaps.
