Sliding Doors Supplier & Exporters Serving Austria

Alpine Climate & OIB Guideline 6 Directives

Austria’s geographical location dictates rigorous building physics performance. From urban high-rises in Vienna to luxury alpine chalets in Tyrol, Salzburg, and Vorarlberg, fenestration systems must withstand extreme thermal differentials. Under Austria’s updated OIB Guideline 6 (Energieeinsparung und Wärmeschutz), residential and commercial buildings demand exceptionally low overall thermal transmittance values (Uw ≤ 0.8 to 1.1 W/m²K). Standard aluminum sliding frames without multi-chamber thermal breaks fail to meet these stringent Austrian building codes.

Ningbo Novax delivers specialized sliding door profiles equipped with multi-cavity Polyamide (PA66 GF25) thermal barriers, warm-edge spacers, and triple-glazing options filled with 90% Argon gas, successfully achieving heating load reductions that fulfill both OIB guidelines and Passivhaus Austria standards.

Wind Load Resistance & Driving Rain Proofing

In mountainous regions, high-altitude wind pressure combined with heavy alpine snow loads and driving rain poses significant risks of air infiltration and water ingress. Standard patio sliders often experience frame deflection under mountain gale pressures exceeding 1600 Pa.

Novax heavy-duty sliding systems are structural-load tested up to EN 12210 Class C5 wind pressure resistance, EN 12207 Class 4 air tightness, and EN 12208 Class E1050 watertightness. Our lift-and-slide (Hebeschiebetür) mechanisms drop the sashes directly onto double continuous EPDM perimeter seals, ensuring an airtight envelope that blocks alpine drafts completely.

9 Years Industry & 6 Years Global Export Expertise

Rooted in 9 years of specialized architectural fenestration production and 6 years of international trade, Novax exports directly to high-standard markets across North America, the Caribbean, South America, and Europe. Our 60 QC personnel conduct rigorous structural load testing, simulated hurricane pressure cycles, and laser alignment diagnostics for every sliding door frame leaving our factory line.

Strategic Material Network (1,100 Suppliers)

Backed by long-term strategic raw material partnerships with 1,100 vetted suppliers, Novax ensures consistent access to prime-grade aluminum alloy EN AW-6063 T6, Siegenia/Gu/Roto German hardware, and Saint-Gobain energy-efficient Low-E glass coatings. Last year alone, our 72 R&D engineers brought 85 new innovative window and sliding door models to global markets.

ÖNORM B 5320 Sealing System

Our sliding door perimeter sub-frames are engineered for seamless compatibility with ÖNORM B 5320 installation practices—incorporating inside vapor-tight sealing tapes and outside weather-resistant, vapor-permeable membranes.

CE & EN 14351-1 Certification

All Novax export products bear full CE marking under EN 14351-1 (Windows and doors product standard). Detailed Declaration of Performance (DoP) documentation is supplied for immediate municipal building permit approval in Austria.

Smart Sensor & Automation Ready

Optionally integrated hidden magnetic contact sensors (compatible with KNX / Loxone smart home systems popular in Austrian modern villas) and motorized drive mechanisms for barrier-free accessibility.
