Fereastră PVC-ALUMINIU KV440 Home Pure — Triplu, Passivhaus

The PVC-Aluminium KV440 Home Pure window delivers exceptional thermal insulation at 0.64 W/(m²K) and acoustic protection up to 45 dB, perfect for passive houses and premium retrofits. Triple-glazed system with three-sealing-line design and integrated ventilation and blind options.

The KV440 Home Pure PVC-Aluminium window is Internorm's response to modern living demands – a synthesis of energy efficiency and refined comfort. Engineered to Austrian standards, the Home Pure series addresses discerning homeowners seeking premium performance without compromise. The hybrid profile combines the thermal responsiveness of interior PVC with the structural integrity and exterior elegance of aluminium, creating a seamless interface between indoor sanctuary and landscape.

The triple-glazing system employs advanced insulating chambers and low-emissivity coatings that retain heat during cold months while managing solar gain. The thermal insulation value Uw of 0.64 W/(m²K) positions the window in the passive house category, certified to PassivHaus standards. Three-line sealing – on the frame's operating edge, between frame and glass, and on the interior profile – prevents air infiltration and water penetration even under extreme weather. Permeability and wind resistance are validated against EN 12208 specifications.

Acoustic performance reaches 39–45 dB, recommended for high-traffic areas or noise-sensitive environments. Laminated glass thickness and internal damping systems suppress sound transmission effectively, delivering tranquillity in urban settings. RC2 burglary resistance classification provides robust protection against forcible entry attempts, suitable for standard residential security requirements.

Home Pure design embraces understated elegance – slender profiles, concealed hardware, and clean transitions between interior and exterior frames. Integrated features – motorised blinds with smart controls and I-tec Ventilation (controlled air exchange without traditional window opening) – transform the window into a complete comfort ecosystem. Colour and finish options adapt to personal preference and existing architecture.

KV440 Home Pure is the definitive solution for new passive houses, energy-retrofit projects meeting international standards, and residences where indoor air quality and thermal-acoustic separation are non-negotiable. This Austrian-made product guarantees multi-decade durability and minimal operational demand – a long-term investment justified by performance.

The KV440 achieves a Uw value of up to 0.64 W/(m²K), placing it in the highest efficiency class for NZEB and passive house standards. The triple-glazed system with warm-edge spacers and optimized PVC-aluminium profile ensures minimal heat transfer, significantly reducing heating demand.

The external aluminium layer shields the PVC profile from UV radiation and weathering, significantly extending the window's lifespan and maintaining structural integrity over decades. It also offers architectural flexibility, allowing custom finishes and colours that complement any home style.

The KV440 provides acoustic insulation (Rw) of 39–45 dB, effectively reducing road traffic, aircraft, and construction noise. The triple glazing and triple seals ensure superior sound tightness, creating a peaceful living environment regardless of urban noise levels.

The KV440 is certified RC2, providing enhanced resistance against forced entry. Multi-point locking hardware and reinforced laminated glass strengthen the structure, while the high-security locking system operates at multiple contact points, preventing unauthorized opening even under extreme pressure.

The KV440 Home Pure includes the I-tec Ventilation system, enabling controlled air exchange without opening the window—essential for airtight homes like passive houses. Integrated blinds provide adjustable solar protection and natural light control, reducing cooling needs and creating season-adaptive living spaces.

The KV440 is manufactured to custom dimensions and shapes, precisely fitting every window opening in your home. Installation is performed by certified Internorm technicians, ensuring perfect sealing, professional fixation, and compliance with local building codes and NZEB standards.
