Fereastră LEMN-ALUMINIU HF410 Ambiente — Triplu, Passivhaus

Internorm HF410 Ambiente wood-aluminium window with triple glazing and thermal insulation down to 0.64 W/(m²K), PassivHaus certified. Maximum energy efficiency and comfort for contemporary homes.

The HF410 Ambiente series by Internorm represents the perfect balance between aesthetics and Austrian engineering excellence. This wood-aluminium system combines the nobility of solid wood inside with the protection and durability of anodised aluminium outside, ensuring long-lasting performance in any climate.

The window features a triple-glazed profile with Uw values down to 0.64 W/(m²K), PassivHaus certified—proof that your investment in thermal insulation meets the strictest efficiency standards. Low-e glass technology significantly reduces heat loss in winter, while optimised solar protection keeps interiors cool in summer without excessive air-conditioning consumption.

Beyond exceptional thermal performance, the HF410 series offers acoustic insulation of 33–46 dB, depending on the configuration chosen. This is essential for homes in urban areas or near main roads. Additionally, resistance to break-in certifications (RC1N and RC2) guarantee maximum protection against intrusion attempts, without compromising elegant design.

Design flexibility is another significant quality: the HF410 system accepts various RAL colours and natural wood essences, allowing perfect integration into classical, modern, or eclectic architecture. Each project benefits from almost unlimited customisation, from proportions to framing and installation details.

This window is recommended as a priority for passive houses, energy renovations, or new construction projects emphasising durability and long-term comfort. Investment in a PassivHaus-certified system pays for itself through constant reduction of heating and air-conditioning bills.

The triple glazing on the HF410 Ambiente achieves a thermal transmittance of up to 0.64 W/(m²K), meeting strict PassivHaus standards. Each additional glass layer, combined with argon gas, creates thermal barriers that maintain stable indoor temperature and dramatically reduces home energy consumption. For passive houses, triple glazing isn't optional—it's essential to achieve certification.

The timber-aluminium profile of the HF410 Ambiente combines the natural beauty of interior wood with a UV-resistant exterior aluminium casing. Wood provides superior thermal insulation and warm aesthetics, while the aluminium layer protects the window from wind, rain and deterioration without requiring regular repainting. Standard PVC windows are cheaper but don't achieve the same thermal performance or architectural longevity.

The HF410 Ambiente is certified RC1N and RC2, meaning it withstands forced entry attempts and impact. If you want higher security, you can opt for RC3, which includes reinforced multi-point hardware, laminated glass and advanced locking systems. Standard RC2 certification already provides substantial protection for most homes, but the recommendation depends on location and your preferences.

The HF410 Ambiente provides sound insulation of 33–46 dB, depending on glazing configuration and hardware system. In noisy urban areas with heavy traffic, you can achieve 46 dB, which significantly dampens street noise and creates noticeable indoor silence. Triple glazing and the wood profile, which absorbs vibrations, are key factors. For exceptionally loud environments, customised recommendations during installation are essential.

Each HF410 Ambiente is custom-manufactured based on your exact opening measurements. Our team takes precise dimensions, considers sun exposure, levels and mounting conditions. Installation is performed by specialists ensuring perfect sealing, correct warm spacer placement and alignment. The process typically takes 4–6 weeks from order to installation, with post-installation follow-up to verify performance.

The wood profile requires simple annual maintenance—cleaning and, if necessary, a fresh protective coat of lacquer. The exterior aluminium layer is inert and requires no maintenance. Multi-point hardware should be lubricated annually for smooth operation. The HF410 Ambiente has a lifespan of 50+ years with proper care, and major components (glazing, hardware) can be replaced modularly. PassivHaus certification guarantees thermal performance throughout the window's lifetime.
