Fereastră PVC-ALUMINIU KF310 Ambiente — Triplu, Passivhaus

PVC-Aluminium KF310 Ambiente window with innovative profile and triple glazing. Ergonomic design with rounded lines and PassivHaus-certified thermal performance for maximum comfort.

The KF310 Ambiente window from Internorm represents the convergence of contemporary aesthetics and high-performance thermal insulation. The PVC-Aluminium system combines the robustness of aluminium profile, mounted on the exterior face, with the insulating benefits of PVC on the interior. The frame's rounded edges create a distinctive visual signature—a harmonious appearance that adapts seamlessly to both interior spaces and external architectural context. This collection positions itself as a premium solution for renovations and new builds requiring thermal security without compromise on modern design.

The triple glazing configuration, with three glass panes and insulation chambers, achieves a Uw value of up to 0.69 W/(m²K), placing the KF310 Ambiente at PassivHaus standards. The PVC-Aluminium profile accommodates sophisticated glazing, with the option of low-e glass for solar control and energy management. The triple pane provides additional defence against water penetration under pressure, while the internal drainage system preserves structural integrity over the long term.

Acoustic performance ranges from 33 to 45 dB of sound insulation—the spectrum depends on exact air cavity configuration and infill type (argon, krypton). PassivHaus certification confirms that KF310 Ambiente meets the strictest standards for energy conservation and interior thermal comfort, even in Northern European climates. RC2 burglary resistance class provides reliable protection against forced entry, recommended for mid-to-high residential and facilities with elevated security requirements.

The rounded-edge frame delivers architectural refinement—lines are fluid rather than angular, visually reducing the frame's mass and creating pleasant contrast between the window body and walls. A palette of standard RAL colours, including metallic finishes for the aluminium, enables adaptation to any exterior design scheme. The window is available in multiple operating types: tilt-turn, tilt-slide, side-sliding, or hybrid combinations, depending on spatial requirement.

KF310 Ambiente is the intuitive choice for passive houses, retrofit projects with intensive insulation, and homes seeking balance between premium aesthetics and long-term thermal economy. Internorm, a manufacturer with 50+ years of expertise, guarantees reliability and comprehensive after-sales service across Europe. Investment in a PassivHaus-certified window is justified through reduced heating and cooling costs over decades, plus architectural value that does not diminish.

An Uw value of 0.69 W/(m²K) is exceptionally low, placing this window in the PassivHaus category — meaning minimal heat loss. With triple glazing and the warm-edge spacer in the profile, you lose virtually no heat in winter and keep summer heat out, significantly reducing your heating and cooling bills.

RC2 designation means this window resists attacks with common tools and provides a minimum 3-minute resistance to break-in attempts. Triple glazing adds an extra physical barrier — each pane must be broken, and the multi-point locking hardware in the Internorm PVC-aluminum profile engages at 4 points, distributing force and making forced opening extremely difficult.

The exterior aluminum on the KF310 Ambiente provides maximum UV protection and long-term architectural durability. Metal profiles resist extreme weather, moisture, and temperature fluctuations without warping, while the interior PVC ensures superior thermal insulation. The innovative design with rounded lines stays pristine regardless of climate conditions.

Rw of 33–45 dB varies depending on your chosen configuration — with triple glazing and optimized spacing, this window provides significant attenuation of street and environmental noise. A 33 dB reduction means half the sound energy reaches inside; at 45 dB, noise drops dramatically and the space becomes quiet even in busy neighborhoods.

The KF310 Ambiente window is manufactured to your exact measurements — Internorm PVC-aluminum accepts minimal tolerances for a perfect fit in any existing frame. Installation is done with full profile anchoring and polyurethane sealing to prevent water and air infiltration. A specialist measures on-site and adjusts dimensions, ensuring full thermal and acoustic performance post-installation.

Internorm PVC-aluminum requires minimal maintenance: annual cleaning with water and neutral detergent, and light lubrication of the hardware. The exterior aluminum needs no repainting, and PVC does not crack, warp, or degrade under UV exposure. Over the long term (15-20 years), sealing gaskets may need replacement, but the structural profile remains intact and thermal performance is maintained, confirming your investment in quality.
