Fereastră PVC-ALUMINIU KF310 Home Pure — Triplu, Passivhaus

Internorm KF310 PVC-aluminium window with triple glazing and exceptional thermal insulation (Uw 0,69 W/m²K), PassivHaus certified. The clean-lined Home Pure design integrates seamlessly into any architectural style.

Internorm's Home Pure series redefines the standard for energy-efficient windows in contemporary building. The KF310 model, manufactured from PVC-aluminium using Austrian engineering, combines extreme performance with architectural proportions that emphasize simplicity and clarity. The robust profile and straight lines do not dominate facades aggressively; instead, they recede elegantly to support the overall design language of the building.

The three-chamber peripheral construction ensures undeniable thermal performance. Triple-glazed units with low-e coating significantly reduce heat loss, resulting in a Uw value of 0,69 W/(m²K) — a specification that places the KF310 in the passive house window category. The aluminium outer layer protects the PVC profile from direct UV exposure and weathering, extending durability and maintaining a clean, easy-to-maintain appearance. These combined characteristics make KF310 a robust choice for renovations and new builds in temperate climates.

Acoustic insulation is equally impressive: Rw values between 33–45 dB enable significant reduction of traffic, industrial, or urban noise. The RC2 burglary resistance class provides additional security without compromising aesthetics — the glazing resists breaking attempts and delays unauthorised access. Windows are tested and certified for wind and water resistance, guaranteeing long-term durability even under harsh weather conditions.

The Home Pure design avoids gratuitous ornamentation. Straight edges and austere proportions create a pure horizontal and vertical language, equally suitable for minimalist modern homes and classical building renovations. The absence of decorative details allows architectural plasticity to dominate, with windows becoming the discrete and refined expression of the house.

KF310 is recommended for owners who prioritise energy efficiency, interior comfort, and longevity. PassivHaus certification confirms compliance with the strictest international insulation standards. Austrian precision and timeless design guarantee an investment that retains value and relevance for decades.

The Uw coefficient measures how much heat escapes through the window—lower values mean better insulation. At 0.69 W/(m²K), the KF310 performs at the top tier, rivaling well-insulated walls. Over a heating season, superior thermal performance translates to measurable savings on your energy bill, especially in colder climates where windows are a major heat-loss point.

The aluminum exterior shields the PVC core from UV radiation and weathering, significantly extending the window's lifespan and maintaining structural integrity. It also offers superior architectural flexibility: the aluminum can be painted any color independent of the interior PVC, allowing seamless façade designs without sacrificing thermal or acoustic performance. KF310 leverages this hybrid strategy, combining PVC's insulation strength with aluminum's durability and refined appearance.

The triple glazing in KF310, with acoustic insulation Rw ranging from 33–45 dB, delivers remarkable noise reduction. This performance range depends on the gas layer configuration and glass thickness you choose at ordering: for high-traffic areas, configurations with warm spacers and argon or krypton gas can attenuate sound by up to 45 dB. Practically: normal outdoor conversation becomes barely audible inside, and heavy traffic fades to a distant rumble.

RC2 is a European classification testing window resistance to basic forced-entry attempts: safety glass (triple, in KF310's case), certified multi-point hardware, and reinforced PVC-aluminum framing provide a minimum 3-minute barrier against common tools. While RC3 (5 minutes) offers heightened protection, RC2 is the standard for typical residential use and moderate-risk areas, striking the right balance between security and cost.

The KF310's PassivHaus certification (with Uw 0.69 W/m²K) confirms it meets Europe's most stringent energy-efficiency standard. Triple glazing, warm spacers, and noble gas deliver the maximum performance required for PassivHaus and NZEB buildings, where windows must actively contribute to thermal envelope integrity. Practically, KF310 enables ultra-efficient construction or renovation, qualifying for green subsidies and favorable financing programs.

KF310 is installed in the masonry of your existing opening, with tolerance for height and width variations requiring precise on-site measurement. Internorm offers made-to-order production for any standard or custom size: showroom specialists can measure for free to ensure perfect fit within your building structure. After fabrication, installation requires professional foam sealing and silicone caulking, handled by qualified installers.
