Fereastră PVC KF410 Ambiente — Triplu, Passivhaus

Internorm KF410 Ambiente PVC window with triple glazing and advanced I-tec technology. Superior thermal insulation (Uw 0.62 W/m²K) and PassivHaus certified for maximum comfort.

The KF410 Ambiente series from Internorm's portfolio represents a high-performance PVC window solution designed for modern homes requiring superior thermal insulation. Built with solid, durable PVC profiles according to Austrian quality standards, these windows guarantee longevity and reliable operation across decades. The design seamlessly integrates with contemporary architectural trends, where energy efficiency meets sophisticated aesthetics without compromise.

Construction relies on triple glazing to deliver exceptional thermal protection and substantial noise reduction from external sources. The low-emissivity glass system with advanced I-tec technology significantly enhances thermal insulation performance, achieving Uw values down to 0.62 W/(m²K) — placing this window among the most efficient solutions available today. Acoustic insulation performance ranges from 34–47 dB depending on configuration, creating a serene indoor environment regardless of external noise levels.

This exceptional thermal performance is validated by PassivHaus certification, an international standard guaranteeing strict energy efficiency criteria. This makes KF410 Ambiente an ideal choice for deep renovation projects and new builds targeting low energy consumption standards. RC2 burglar resistance classification provides solid security protection, defending against unauthorized entry attempts. Water and wind resistance are engineered to withstand diverse climate conditions while maintaining consistent performance over extended periods.

The elegant PVC profile design from the Ambiente series adapts effortlessly to various architectural styles, from traditional residences to contemporary structures. Slender profiles maximize natural light penetration into interior spaces, creating brighter, more open environments. Installation follows local standards with adaptability to different frame types and masonry configurations.

This window is particularly recommended for temperate and continental climates where seasonal temperature variations are significant. Investment in a KF410 Ambiente product rapidly offsets heating costs and substantially improves long-term residential comfort and energy performance.

Uw measures heat loss through the window—the lower the value, the better the thermal insulation. At 0,62 W/(m²K), KF410 Ambiente meets Passive House and NZEB standards, reducing heating costs and maintaining comfort year-round. The triple glazing and warm spacer bar are key to this performance.

Triple glazing traps more insulating air between panes, delivering superior thermal and acoustic performance. In KF410, the combination with argon or krypton gas and advanced PVC profile creates a denser thermal and acoustic barrier. In continental climates, you'll notice lower heating costs and reduced street noise—an investment that pays for itself in 5–7 years.

RC2 (burglar resistance class 2) means the window resists break-in attempts using common tools like crowbars. KF410 combines reinforced glazing (>4 mm per pane), multi-point hardware with adjustable locking, and strengthened anchors. DIN EN 1627 certification guarantees lab-tested performance—ideal for urban settings and homes with medium security needs.

Rw (weighted sound reduction index) measures dB lost as noise passes through the window. The difference between 34 and 47 dB is significant: 34 dB reduces noise by ~50%, while 47 dB reduces it by ~99.9%—nearly silent. KF410 reaches the upper spectrum thanks to triple glazing, PVC profile with sealed chambers, and dense hardware. For a busy street, 47 dB is critical.

KF410 Ambiente is available in a wide range of standard PVC colors (white, gray, anthracite, beige) and custom profiles can be ordered with matte or glossy finishes. The PVC profile offers versatility for integration into any architectural style—from historic buildings to modern minimalist. For premium requirements, special foils can be applied to mimic wood or other finishes while retaining PVC benefits.

KF410 is custom-ordered based on your opening's exact measurements—no standard sizes that don't fit. Installation uses a warm mounting profile around the frame for perfect thermal sealing and proper water drainage. A specialist measures on-site and assesses the opening condition; installation takes 2–4 hours depending on complexity. Warranty covers installation defects for 5 years.
