Fereastră PVC KF310 Ambiente — Triplu, Passivhaus

Internorm KF310 Ambiente PVC window with triple glazing and PassivHaus certification delivers outstanding thermal insulation (Uw = 0.69 W/m²K) and acoustic protection up to 45 dB for superior comfort.

The Internorm KF310 Ambiente PVC window represents the pinnacle of high-performance fenestration technology. Engineered with Austrian precision and PassivHaus-certified, this collection is designed for homes pursuing minimal energy consumption, seamlessly serving both new constructions and ambitious renovation projects.

The PVC profile integrates advanced I-tec insulation technology, which minimizes thermal bridges and optimizes temperature distribution within the frame. The triple-glazed configuration features high-performance low-e coatings, achieving a Uw value as low as 0.69 W/(m²K) — a benchmark placing KF310 Ambiente among the world's most energy-efficient windows. The system allows comfortable operation while maintaining a balanced frame depth without compromising interior space.

Acoustic insulation rated at Rw 33–45 dB transforms interiors into peaceful sanctuaries regardless of urban or traffic noise. The frame structure and precision sealing materials ensure consistent sound separation. Simultaneously, RC2 security certification provides solid protection against forced entry, with resistant glazing and robust locking mechanisms — making KF310 suitable for urban residences in exposed locations.

The KF310 Ambiente design embodies Viennese minimalism: pure proportions, refined surfaces, and a compact profile that integrates discreetly into any modern architectural context. Available in classic white and neutral finishes, the frame harmonizes effortlessly with contemporary or traditional facades. Generous glazed areas and slender sightlines maximize transparency and natural light, essential for psychological comfort in living spaces.

KF310 Ambiente is particularly recommended for apartment renovations in residential blocks and houses, as well as for new passive buildings. Internorm understands that windows are more than barriers — they are the interface between interior and world. With rigorous certifications and Scandinavian-European tested materials, each window guarantees performance across decades.

The KF310 achieves a thermal transmittance (Uw) of just 0.69 W/(m²K), placing it among the finest windows for near-zero energy buildings and passive houses. This exceptionally low U-value results from the optimized PVC profile, triple glazing with warm-edge spacers, and inert gas filling, ensuring minimal heating costs and consistent performance throughout winter.

The KF310 delivers sound insulation ranging from 33 to 45 dB, adjustable based on the thickness and composition of the triple glazing selected. This range covers residential properties in urban and suburban settings, offering significant acoustic comfort for homes exposed to moderate traffic noise. For more demanding environments close to highways, specialized asymmetric glazing variants with optimized acoustic spacers are available.

The KF310 is certified RC2, a standard guaranteeing tested resistance against forced entry attempts using common hand tools such as hammers and screwdrivers. RC2 classification includes high-performance multi-point locking hardware and robust PVC profile, offering effective protection against opportunistic intruders and ideal for homes in medium-risk areas. For heightened security requirements (RC3 with powered tool resistance), specialized upgrades are available.

The KF310 is constructed from high-grade PVC, a dimensionally stable material that resists warping and requires no painting. The PVC profile naturally resists UV radiation and withstands intense rain and extreme temperature cycling without degradation, maintaining whiteness and operational smoothness throughout its lifespan (minimum 30–40 years). Maintenance is minimal—periodic cleaning with water and mild detergent suffices, without need for aggressive chemical treatments.

Yes, the KF310 is manufactured to order in exact dimensions matching your opening and is not restricted to standard sizes. The Internorm PVC profile accommodates a broad colour palette—white (standard), grey, brown, and subtle passive tones—tailored to your architectural preferences and home style. During installation, the team measures precisely and adjusts seals and hardware for perfect fit and smooth operation.

KF310 installation requires precise opening measurements and skilled technical work for sealing and structural fixation. Expanding foam panels and silicone gaskets ensure final thermal and acoustic performance—poor installation compromises both Uw-value and sound insulation. We recommend engaging a certified Internorm installer who guarantees PassivHaus compliance and prevents common issues such as condensation and water infiltration.
