Fereastră PVC-ALUMINIU KF410 Home Pure — Triplu, Passivhaus

Internorm KF410 Home Pure PVC-Aluminium window with triple glazing and PassivHaus certification. Thermal value down to 0.62 W/(m²K) for superior energy efficiency and refined comfort.

The KF410 Home Pure window represents Internorm's premium range, where Austrian engineering excellence meets contemporary minimalist design. The combination of PVC profile with external aluminium cladding delivers durability, weather protection, and architectural refinement for any modern façade.

Triple low-e glazing paired with I-tec insulation technology significantly reduces heat loss. The Uw value reaches 0.62 W/(m²K), a performance level that meets PassivHaus standards and suits both deep energy renovations and new passive house projects. Sound insulation Rw between 34–47 dB creates a quiet interior sanctuary, even in bustling urban environments.

RC2 security classification ensures proven resistance to attempted break-ins. Triple glazing provides not only thermal and acoustic performance but also protection against accidental impact and dynamic pressure. Water drainage and wind-tight sealing systems are managed by elastic-core profiles, tested to rigorous European standards for long-term reliability.

The frameless design of KF410 Home Pure allows slim sightlines and modern proportions, integrating seamlessly into minimalist architecture, passive houses, or renovations where natural light is paramount. Available in standard chrome finishes and custom RAL options.

This window suits discerning owners who value measurable comfort and verified energy efficiency over decades. Professional installation following Internorm guidelines ensures full performance and longevity.

PassivHaus is an international certification guaranteeing exceptional thermal performance — for the KF410, a Uw value down to 0.62 W/(m²K) means minimal heat loss, even in harsh winters. This window is engineered for passive houses and NZEB standards, where every detail counts for indoor comfort and lower heating bills.

The PVC-Aluminium structure combines the benefits of both materials: the PVC interior provides superior thermal insulation and lightweight qualities, while the aluminium cladding on the exterior façade protects the window against UV radiation and weather, maintaining colour and integrity for decades. This design ensures architectural durability and consistent performance regardless of exposure.

The triple glazing on the KF410, combined with RC2 classification, provides protection against dynamic break-ins over a specified timeframe — the glass withstands tool strikes and brute force for at least 3 minutes. High-security multi-point locking hardware reinforces resistance: ideal for residential properties in urban areas or sensitive locations where protection is a priority.

The KF410 Home Pure provides acoustic insulation in the 34–47 dB range, depending on configuration: lower values address light noise (light traffic, conversation), while 47 dB offers solid protection even against heavy traffic, train stations, or nearby airports. The combination of triple glass with warm spacer and argon gas optimises acoustic dampening for quiet living spaces.

The KF410 requires minimal maintenance: the PVC profile is cleaned with lukewarm water and gentle detergent, no abrasives; the external aluminium cladding is cleaned the same way but tolerates weathering better. Drainage and weepholes should be inspected annually to prevent deposit buildup — simple care ensures functionality and aesthetic appearance for 20+ years without degradation.

Yes, the KF410 Home Pure is available custom-sized and dimensioned to order, tailored to your space requirements — whether standard sizes, unusual formats, or multiple configurations (twin openings, alcoves, sloped installations). The mounting and sizing process is handled by Internorm specialists who ensure precision and compatibility with your home's structure, guaranteeing airtightness and optimal thermal performance.
