Fereastră PVC-ALUMINIU KV440 Ambiente — Triplu, Passivhaus

The Internorm KV440 Ambiente combines PVC-aluminium profile with triple glazing and PassivHaus-certified thermal insulation, delivering superior solar control, thermal efficiency and acoustic comfort.

The Internorm KV440 Ambiente is an innovative solution for properties requiring maximum thermal performance and intelligent solar control. The PVC-aluminium profile combines PVC's thermal insulation flexibility with aluminium's elegant and durable exterior appearance, positioning this system in the premium market segment.

The triple-glazed construction with a 6-chamber profile achieves a Uw value of up to 0.64 W/(m²K), meeting PassivHaus standards. Glass thickness and low-e coating reduce thermal losses in winter while controlling solar radiation in summer, creating perfect balance between comfort and energy efficiency throughout the year.

Acoustic performance of Rw 39–45 dB effectively isolates external noise, while RC2 security classification provides additional protection against manual forced entry. Profile thickness and multi-chamber sealing system ensure superior resistance to water and wind infiltration—critical in variable European climates.

Ambiental design integrates blinds and I-tec ventilation systems seamlessly, transforming the window into a fully automated solution. The PVC profile accepts a wide range of RAL colours and finishes, while aluminium components can be customised to suit any modern or classical architecture.

Recommended for passive houses, thermal renovations and high-insulation buildings, the KV440 Ambiente is the ideal investment for owners who refuse compromise on quality and long-term durability.

The aluminum exterior cladding protects the PVC core from UV degradation and weathering, maintaining appearance and performance over decades. Aluminum also delivers refined architectural lines, perfect for contemporary facades, while preserving the superior thermal insulation of the inner PVC chamber.

Triple glazing with Uw 0.64 W/(m²K) is PassivHaus certified and essential for ultra-low-energy buildings and passive houses. If your home meets NZEB (nearly zero-energy) standards or maximizes insulation, triple glazing virtually eliminates heat loss at the window and stabilizes indoor temperature consistency. For standard homes, quality double glazing offers excellent value; triple becomes worthwhile for premium renovations or high-performance new builds.

RC2 (Resistance Class 2) certifies that frame and glazing withstand forced entry attempts with basic tools – hammer, pry bar – for minimum 3 minutes. Internorm's multi-point hardware means 5–6 locking points along the sash height, distributing stress evenly and preventing hinge or latch failure. The combination of impact-resistant glazing and reinforced profile creates a genuine barrier against opportunistic theft.

Rw (weighted sound reduction index) of 39–45 dB means the window attenuates external noise by 39–45 decibels – heavy traffic becomes a quiet hum, loud voices fade away. Triple glazing with warm-edge spacers and inert gas (argon/krypton) creates unequal air chambers that absorb sound vibrations across multiple frequencies. For homes in busy urban areas, values above 40 dB guarantee significant comfort.

KV440 Ambiente installs using universal mounting in existing or new frame cavities, with adhesive sealing strips and mechanical anchors for secure fixing. Dimensions are custom-sized to order – you choose any width and height within structural limits. Installation requires skilled technicians who follow Internorm standards for proper drainage and thermal-break connection between glass and wall.

The PVC profile requires annual cleaning with water and neutral soap; the aluminum exterior needs no additional maintenance. Triple glazing is hermetically sealed and cannot be opened, preventing condensation issues. Multi-point hardware cleans easily and needs light lubrication every 2–3 years. With regular care, KV440 lasts 50+ years without structural degradation, making it a long-term investment for passive houses and NZEB buildings.
