Fereastră LEMN-ALUMINIU HF410 Studio — Triplu, Passivhaus

The HF410 Studio timber-aluminium window features triple glazing and exceptional thermal insulation of Uw 0,64 W/(m²K), PassivHaus certified for maximum energy performance.

The HF410 Studio is a premium reference window from Internorm's collection, crafted from solid timber combined with an external aluminium profile. This hybrid architecture delivers timeless elegance, exceptional durability, and top-tier energy performance—the ideal solution for major renovations and contemporary passive house projects.

The deep profile of this series accommodates a triple-glazing system with a thermal transmittance value down to Uw 0,64 W/(m²K), positioning it among the market's most efficient windows. Low-emissivity coatings paired with noble gas fills in the sealed cavities create an outstanding thermal barrier throughout all seasons. The premium frame system and triple-stage seals significantly minimize heat loss, translating to measurably lower heating consumption.

The acoustic performance ranges from 33 to 46 dB, providing excellent protection against urban and environmental noise. The robust construction and glazing thickness deliver a burglar-resistance rating of RC1N/RC2, safeguarding your home against forced entry attempts. HF410 Studio holds PassivHaus certification, confirming compliance with the industry's most stringent energy efficiency and indoor comfort standards.

The design of the HF410 exemplifies harmonious proportions and refined timber finishes that integrate seamlessly into both traditional and contemporary architecture. Interior timber can be customized to match individual aesthetic preferences, while the external aluminium profile provides lasting weather protection with minimal maintenance.

This series is recommended first and foremost for energy retrofits, passive houses, and residences in demanding climates. Investing in an HF410 Studio window means permanent thermal comfort, measurably reduced energy bills, and significant added value to your property.

Triple glazing in the HF410 Studio delivers thermal insulation with Uw values down to 0.64 W/(m²K), cutting heat loss by up to 40% compared to conventional double glazing. This translates directly into lower heating bills and consistent comfort during winter. Additionally, the acoustic performance of Rw 33–46 dB significantly reduces external noise, essential for homes in urban areas or near busy roads.

Yes, the HF410 Studio is PassivHaus certified, meeting the rigorous standards required for passive houses and NZEB (Nearly Zero Energy Buildings). The thermal coefficient Uw of 0.64 W/(m²K) places this window in the high-performance category necessary to maintain stable indoor climate with minimal energy consumption. This makes it ideal for retrofitting older buildings or new constructions with superior energy efficiency goals.

The exterior aluminium on the HF410 Studio shields the internal wood from direct UV exposure, rain, and wind, eliminating the need for frequent repainting and significantly extending lifespan. Indoors, the wood remains visible and breathes naturally, maintaining warmth and classic aesthetics, while aluminium provides a protective barrier. This wood-aluminium design combines the enduring beauty of wood with the practical durability of aluminium, ideal for Europe's variable climate.

RC2 (Burglary Resistance Class 2) on the HF410 Studio means the multi-point hardware and triple glazing are engineered to resist manual tool attempts for at least 3 minutes, which deters opportunistic break-ins. This certification is mandatory in many urban areas and recognised by insurance companies, which often offer premium reductions for RC-certified windows. For homes in city centres or high-risk security zones, RC2 provides optimal balance between protection and everyday usability.

The HF410 Studio is a custom-made product with flexible sizing options, meaning our technical team works with you from measurement through installation. We recommend an on-site inspection by an Internorm specialist who will assess wall thickness, plaster type, and mounting preferences (frame-mounted, wall-mounted, or brick-integrated). The process includes CAD design, written dimension confirmation, and professional installation following PassivHaus standards for optimal thermal sealing.

The HF410 Studio offers flexibility in interior wood finishes (natural linden, oak, custom paint colours) and exterior aluminium in Internorm's colour palette. As a custom product, you can choose protective treatments (lacquer, semi-transparent stain, oil) and profiles with different aesthetics depending on architectural style. We recommend consulting directly with our design team to integrate the window into your home's aesthetic context and verify compatibility with existing windows.
