Engineered to satisfy local energy laws, structural integrity standards, and aesthetic aspirations in Austrian residential and commercial designs.
The Austrian building sector stands at the absolute vanguard of global energy efficiency standards. Governed by the stringent regulations of the OIB (Österreichisches Institut für Bautechnik) Guidelines, specifically OIB Richtlinie 6, new constructions and major renovations in Austria are legally mandated to limit energy use to unprecedented levels. In places like Vienna, Salzburg, and Graz, architectural designs prioritize thermal efficiency, which directly dictates the specifications of building envelopes.
Aluminum fixed windows have transitioned from simple aesthetic choices to critical thermal barriers. Known locally for their structural rigidity and resistance to intense alpine snow and wind loads, these windows must deliver exceptional thermal transmittance values ($U_w$ values). For high-performance passive houses (Passivhaus) in mountainous provinces such as Tyrol and Vorarlberg, windows must demonstrate $U_w \le 0.8\text{ W}/(\text{m}^2\text{K})$, requiring state-of-the-art multi-chamber thermal breaks and triple-glazing with argon gas fills.
Additionally, modern urban planning in Austria demands high acoustic damping ($R_w$ ratings) to combat traffic noise in densely populated areas. As a result, commercial developers and residential architects are increasingly sourcing highly engineered, customized aluminum fixed windows from global manufacturing powerhouses that can deliver on-demand precision, local certificate compliance, and superior cost-effectiveness.
Providing Austrian contractors and distributors direct access to industrial-scale engineering and cost advantages without sacrificing quality.
We work closely with Austrian developers to offer precise profile extrusion configurations, customized architectural powder coatings (such as RAL colors 7016 anthracite grey or custom DB shades), and varied glazing specifications ranging from high-solar-gain double glass to high-performance acoustical triple-glazed assemblies.
By optimizing container packing and cooperating with leading logistics providers, we ensure that pre-assembled, fully glazed aluminum fixed windows arrive in Austria with zero damage. Our products are crated in custom timber boxes designed for rapid forklift unloading on-site in Vienna, Linz, or Graz.
Each production run undergoes structural integrity audits, air infiltration checks, and hydrostatic pressure testing. Our compliance framework guarantees that thermal break barriers (utilizing premium glass fiber reinforced polyamide strips) easily endure temperature differentials between sub-zero Austrian winters and hot summers.
Fixed windows, while mechanically simpler than operable casement windows, demand advanced materials science to guarantee architectural longevity. Without operable sashes to relieve structural loading, thermal expansion and structural wind shear act directly on the frames and glass panes. Here is the technical overview of our product design philosophy:
Our aluminum profiles feature specialized multi-chamber designs featuring Polyamide (PA66 GF25) thermal barriers. This isolation effectively breaks the thermal bridge between the exterior and interior aluminum skins, drastically reducing the U-factor of the frame ($U_f$). By filling these chambers with low-conductivity insulating foams, we satisfy the rigid standards of the European energy rating systems.
Windows can be specified with double or triple insulated glass units (IGUs) incorporating low-emissivity (Low-E) coatings. Low-E coatings selectively reflect infrared heat while allowing visible light to pass through. Additionally, we use warm-edge spacers (such as stainless steel with composite polymer) to prevent condensation at the glass perimeter—a vital requirement for Austrian winters.
Fixed glass panes are glazed from the inside to prevent unauthorized removal of the glass panels from the exterior. For floor-to-ceiling panoramic configurations, we utilize laminated safety glass (LSG) complying with EN 12600 to prevent accidental fall-through, while heavy-duty EPDM gaskets maintain hermetic air and water seals under extreme wind pressures.

By integrating high-density polyurethane thermal foam fills inside our multi-cavity thermal break polyamide profiles and combining them with triple-pane double-Low-E glass ($4\text{mm} \times 2 + 4\text{mm}$ safety glass) filled with 90% Argon gas, we can achieve $U_w$ values as low as $0.78\text{ W}/(\text{m}^2\text{K})$. This ensures compliance with passive house parameters in high-altitude Austrian developments.
Compliance with ÖNORM B 5320 is mainly achieved through installation detail planning. We manufacture our fixed windows with pre-engineered perimeter grooves to accept local thermal expansion expansion joints, dynamic sealing tapes, and vapor-barrier membranes. We also supply custom anchor brackets designed to handle the heavy weights of triple-glazed fixed units without damaging thermal insulation layers.
Our window systems are tested according to EN European standards: EN 1026 for Air Permeability (Class 4), EN 1027 for Watertightness (Class E900), and EN 12211 for Wind Load Resistance (Class C5). Test certificates are available upon request for verification during building control audits.
Yes. We specialize in extra-large viewing windows. We increase frame wall thicknesses to 3.0mm and incorporate internal steel reinforcements. We pair this with tempered or laminated safety glass configurations (up to 12mm thickness per pane) to safely withstand the massive wind pressures and snow loads encountered in places like Vorarlberg and Kitzbühel.
Typically, design drawing confirmation takes 5-7 days. Production of a standard project order takes 30-35 days, and sea freight shipping to major European logistics hubs with rail/truck transfer to Austria takes about 35-40 days. In total, expect custom windows on-site within 75-80 days from deposit payment.
