Fereastră LEMN-ALUMINIU HF510 Home Pure — Triplu, Passivhaus

HF510 Home Pure wood-aluminium windows from Internorm. Uw 0.65 W/(m²K), triple glazing and PassivHaus certification for ultimate comfort.

The Internorm Home Pure series represents the pinnacle of design and performance in wood-aluminium window engineering. The HF510 model is crafted for homeowners who refuse to compromise between the warmth of natural wood and modern durability. The exterior aluminium cladding protects the timber core, ensuring exceptional longevity while minimising maintenance demands.

Constructed with noble-timber profiles and anodised aluminium cladding, the HF510 delivers refined robustness. Triple-glazed PassivHaus-certified units achieve exceptional thermal values, with a Uw rating down to 0.65 W/(m²K)—placing this window in the elite bracket for energy efficiency. Acoustic insulation ratings of 35–47 dB Rw create a serene interior environment, even in busy urban settings.

Robust sealing integrity and RC1N and RC2 security classifications safeguard against powerful wind loads and forced-entry attempts. Triple-rebated seals with premium gasket materials maintain thermal and acoustic performance over decades. PassivHaus certification validates that HF510 meets the world's strictest standards for near-zero-energy buildings.

The HF510 Home Pure aesthetic merges clean contemporary lines with the organic character of timber. Available in natural tones and lacquered finishes, it integrates seamlessly into period renovations and avant-garde designs alike. The refined profile geometry ensures precise installation and uncompromising visual coherence.

This is the definitive solution for high-performance renovations and passive-house builds across temperate and continental climates. Choosing HF510 Home Pure means investing in decades of energy savings, thermal comfort, and the quiet satisfaction of a home built to last.

HF510 Home Pure combines a solid wood frame with exterior aluminium protection, achieving thermal performance of Uw = 0.65 W/(m²K) and PassivHaus certification. The wood-aluminium structure delivers superior insulation, long-term durability, and natural aesthetics indoors, while the exterior aluminium resists UV and weather damage.

Yes, HF510 is PassivHaus-certified due to its extremely low Uw value (0.65 W/(m²K)) and advanced thermal insulation with triple glazing. This performance makes it ideal for passive houses and NZEB projects requiring minimal heat loss through windows.

HF510 is available in RC1N and RC2 classifications, with optional multi-point hardware and laminated glass for enhanced protection. RC2 rating provides resistance against basic forced entry attempts with common tools, ensuring a solid security level for residential homes.

HF510 provides acoustic insulation Rw in the range of 35–47 dB, varying depending on glass configuration and spacer type. The combination of triple glazing with warm spacers and noble gases (argon/krypton) ensures effective outdoor noise reduction, performing excellently in urban areas or near busy roads.

HF510 is fully custom-manufactured in bespoke dimensions according to your opening measurements. Internorm's professional installation team ensures proper installation to NZEB standards, with correct sealing and drainage to prevent water infiltration and optimize thermal performance.

HF510 is engineered for a lifespan of 40+ years thanks to its wood-aluminium structure and quality finishes. Maintenance is minimal: annual rinse with water and mild soap, lubrication of the operating mechanism, and periodic sealing checks. The exterior aluminium requires no painting, while the interior wood can be oiled or repainted as desired.
