PVC-steel Windows for Home Use

Modern homes demand window solutions that combine robustness with thermal performance, and PVC-steel composite designs deliver exactly that. Our range of Steel Reinforced PVC Composite Windows integrates galvanized steel cores within multi-chambered uPVC profiles to eliminate warping while achieving outstanding insulation values. For spaces requiring flexible ventilation and effortless cleaning, the Tilt and Turn PVC-steel Composite Windows mechanism allows both side-hung inward opening and a tilted position for draught-free air circulation. Homeowners looking for tailored residential applications will appreciate our Residential PVC-steel Composite Windows, optimized for bay windows, cottage sashes, and modern glazing extensions. Meanwhile, larger-scale projects or mixed-use buildings benefit from the enhanced structural capacity of our Commercial PVC-steel Composite Windows, engineered to accommodate oversized panes and frequent daily operation without degradation. Each window series undergoes rigorous thermal cycling, air permeability, and water tightness testing to meet EN 14351-1 standards, ensuring decades of reliable performance in diverse climates.

Introducing ThermoGuard PVC-Steel Windows, a purpose-built system that redefines residential fenestration. The heart of ThermoGuard PVC-Steel Windows lies in its fully bonded 1.5 mm galvanized steel reinforcement that runs continuously through the frame and sash, eliminating differential expansion between materials. Five internal air chambers plus a co-extruded dual-durometer gasket system achieve a U-value as low as 0.71 W/m²K when paired with triple glazing, effectively minimizing cold bridging. ThermoGuard PVC-Steel Windows employ a fusion-welded corner construction method on the uPVC profile, combined with mechanical steel corner cleats, producing a frame rigidity rating of RC 3 in the resistance class system. This hybrid design handles glass weights up to 180 kg per sash, enabling floor-to-ceiling panoramic installations that maintain smooth operation over 25,000 open/close cycles. The surface is finished with a UV-stabilized acrylic layer available in over 30 RAL colors and woodgrain foils, resisting color fade even under intense sun exposure. Internally, the multi-point locking mechanism engages four mushroom cams and two deadbolts, delivering a secure lock status that pairs seamlessly with smart home alarm integrations. Hardware components use stainless steel and brass internals with a salt-spray test rating of over 480 hours to prevent corrosion in coastal environments.
