Fereastră LEMN-ALUMINIU HF410 Home Soft — Triplu, Passivhaus

The HF410 Home Soft timber-aluminium window merges natural wood aesthetics with exceptional thermal performance (Uw 0.64 W/m²K) and sound insulation up to 46 dB, PassivHaus-certified.

The HF410 Home Soft timber-aluminium window from Internorm (Austria) is the premium solution for those who value comfort and quality in every detail. Combining solid timber with anodised aluminium on the exterior creates a robust, weather-resistant construction imbued with architectural character. This is a window designed for spaces that deserve nothing less than excellence.

The triple-chamber profile and triple glazing optimise both thermal insulation (Uw up to 0.64 W/m²K) and acoustic performance (Rw 33–46 dB), placing it squarely within passive house standards and high-performance renovations. The exterior aluminium shields the timber core from wind, water and UV damage, while the interior timber maintains warmth and delivers that tangible sense of home. Triple glazing with insulated cavities dramatically reduces heat transfer and dampens external noise—traffic, wind, weather.

PassivHaus certification confirms this window exceeds European comfort benchmarks. Burglary resistance classes RC1N and RC2 provide solid protection against forced entry attempts, strengthening home security. Water and wind resistance meet EN standards, guaranteeing durability and freedom from infiltration even in severe conditions.

Home Soft design embodies subtlety and refinement—softly harmonised profiles and frame depth integrate seamlessly into both heritage and contemporary architecture. The timber allows a broad palette of natural finishes and custom paint options, tailored to each project's identity.

Perfect for new-build passive houses, energy retrofits and traditional masonry or timber structures, HF410 Home Soft delivers the thermal comfort and acoustic tranquillity that transform a house into a true sanctuary. Investment in quality windows always pays back—lower energy bills and daily wellbeing.

Wood provides superior thermal insulation and a warm, natural feel indoors, while the external aluminium cladding protects the structure from weathering and UV damage, eliminating the need for regular repainting. This combination makes the HF410 Home Soft ideal for passive houses and NZEB buildings requiring 0.64 W/(m²K) thermal performance.

Yes, HF410 Home Soft is PassivHaus certified with a Uw value of up to 0.64 W/(m²K), placing it in the top category for NZEB buildings. The triple glazing and warm spacer ensure minimal heat loss, essential for maintaining thermal comfort in passively insulated structures.

HF410 Home Soft provides acoustic insulation Rw of 33–46 dB depending on gas configuration and spacer type. This acoustic performance meets requirements for homes in high-traffic areas, significantly reducing street noise without requiring additional soundproofing solutions.

HF410 Home Soft is available in RC1N and RC2 classes, equipped with multi-point hardware ensuring secure closure across the entire window perimeter. RC2 offers additional protection against light force attempts, suitable for urban areas or sensitive buildings requiring elevated security levels without aesthetic compromise.

HF410 Home Soft comes with multiple colour and profile options for the interior wood and exterior aluminium, allowing seamless integration into traditional and contemporary architectures. The exterior aluminium can be lacquered in modern colours or neutral tones, while the interior wood maintains natural warmth, offering design flexibility without thermal performance compromise.

HF410 Home Soft is produced entirely to order according to your dimensions and configuration, including gas specifications (argon or krypton for optimal performance), break-in classes, and accessory options. Installation requires precise conformity with the building location, and measurements by a showroom specialist are recommended to ensure seamless installation and guaranteed thermal insulation performance.
