Fereastră PVC-ALUMINIU KF320 Studio — Triplu, Passivhaus

The Internorm KF320 Studio PVC-aluminium window features triple glazing, frameless design aesthetics, and achieves thermal performance of 0.65 W/(m²K) with acoustic protection up to 45 dB.

The Internorm KF320 Studio series redefines modern window design through a PVC-aluminium profile system that creates a frameless aesthetic. This premium collection addresses residential and commercial projects demanding contemporary minimalism without compromising thermal and acoustic performance.

The KF320 Studio construction relies on triple glazing technology paired with specialized coatings that deliver declared thermal transmittance of 0.65 W/(m²K), meeting Passive House standards. The integration of PVC core with external aluminium laminate both stabilizes the frame during extreme seasonal conditions and enables clean edge finishing. The triple glass benefits from low-emissivity treatments that minimize radiative heat loss, maximizing energy efficiency year-round.

Acoustic performance is equally impressive: sound insulation reaches 34–45 dB depending on configuration, providing excellent protection against street and environmental noise. The RC2 security class certifies resistance against casual break-in attempts, offering peace of mind. The internal and external drainage and sealing system withstands water and wind pressure under severe weather conditions, ensuring long-term durability.

The frameless appearance is the KF320's signature: horizontal and vertical glass lines dominate the view while the profile remains visually discreet. Neutral colour options and compatibility with any modern architectural scheme make these windows ideal for selective renovations and new builds. Flexibility in orientation and dimensions permits maximum design freedom in space planning.

KF320 Studio windows are particularly recommended for passive buildings and homes with ultra-low energy requirements, as well as for standard residences aspiring to superior thermal comfort and acoustic tranquillity. Professional installation following Internorm standards ensures optimal performance of all constructive properties.

The triple glazing combined with the warm-edge spacer in the KF320 Studio profile significantly minimizes heat loss, achieving an Uw value of 0.65 W/(m²K). The exterior aluminium protects the PVC core from UV damage and weather extremes, while argon gas between panes enhances insulation further. This construction makes it ideal for passive houses and NZEB standards.

The KF320 Studio is certified RC2, featuring multi-point hardware that locks the sash at 5–7 points along the perimeter. This distributes force evenly and makes brute-force entry extremely difficult. The robust triple glazing and rigid PVC-aluminium profile further complicate unauthorized access. RC2 rating makes it suitable for residential properties and commercial spaces with moderate security requirements.

The exterior aluminium cladding on the KF320 Studio shields the PVC core from UV radiation and weather degradation, significantly extending the window's lifespan. It also provides enhanced aesthetics with a more architecturally refined appearance, enabling slimmer profiles and larger openings without compromising rigidity. The dual-material design allows exterior colour customization while maintaining classic white interiors.

The asymmetric triple glazing with varying pane thicknesses (typically 4+6+6 mm) reduces resonance and delivers acoustic insulation Rw of 34–45 dB, suitable for moderate traffic areas. The warm-edge spacer and argon gas between panes absorb additional vibration. For high-noise locations (motorways, airports), thicker or laminated glass is recommended. The KF320 Studio ensures optimal acoustic comfort in urban and semi-rural homes.

The KF320 Studio's PVC-aluminium structure allows the exterior in any standard RAL or NCS colour, matched to your home's architecture. The interior remains classic Internorm white for convenience and optimal light distribution, with optional secondary painting if desired. The flush-frame design offers a minimalist, clean appearance. You can also select matte, textured, or glossy finishes on the aluminium for personalized aesthetic effects.

The KF320 Studio is manufactured to your exact dimensions with tightly controlled tolerances. Installation is carried out within the building structure using sealed EPDM tape and water-shedding isolation on side walls; minimal repair space is needed. Installation must be performed by Internorm-certified fitters to guarantee thermal and acoustic sealing. Post-installation requires only minor hardware micro-adjustments by the installer.
