Internorm HF510 Home Pure timber-aluminium window with triple glazing and thermal insulation down to 0.65 W/(m²K). Premium solution certified PassivHaus for superior thermal and acoustic comfort.

HF510 Home Pure represents maturity in premium window design. Internorm, an Austrian manufacturer with a tradition of excellence, combines timber-aluminium construction for perfect architectural integration — noble wood interiors offer warmth and elegance, exterior aluminium protects and modernises the facade.

The profile incorporates high-performance triple glazing with thermal insulation value Uw down to 0.65 W/(m²K), performance that places this window in the segment of passive buildings and top-tier renovations. The multi-chamber sealing system and glass thickness are optimised to deliver long-term stability and minimise heat loss, essential in Central European climates and regions with rigorous winters.

Acoustic insulation Rw between 35–47 dB ensures peace and tranquility indoors, regardless of street noise. Burglary resistance classification RC1N and RC2 indicate robust security levels, with break-resistant glass, ideal for homes in urban areas or high-traffic zones. PassivHaus certification confirms that windows meet Europe's strictest sustainable construction standard.

The HF510 Home Pure design adapts effortlessly to modern architectures and authentic restorations. Gently rounded profiles and balanced proportions fit contemporary homes and heritage buildings alike. Installation and framing are executed to excellence standards, with meticulous attention to detail and durability.

This window is the perfect investment for owners who make no compromises: energy efficiency, excellent acoustics, security and timeless design together in a single solution. Recommended for passive houses, open-air renovations and high-class residential buildings in any temperate climate.

The HF510 Home Pure achieves a U-value of up to 0.65 W/(m²K), thanks to the wood-aluminium frame and triple glazing with warm spacer technology. This performance meets PassivHaus standards, meaning your home requires minimal heating even during harsh winters.

The exterior aluminium layer shields the wood from direct sun, rain, and UV exposure, ensuring decades of durability without deterioration. The solid wood interior provides superior thermal insulation and natural aesthetics, while the aluminium exterior guarantees flawless function and appearance for years.

The window meets RC1N and RC2 certification standards with multi-point locking hardware that secures the entire frame perimeter. The dual rating lets you choose the protection level you need: RC1N for standard security or RC2 for reinforced resistance against prying and forced-entry attempts.

The window delivers sound insulation rated Rw 35–47 dB, significantly reducing traffic noise, construction sounds, and urban ambient noise. The triple glazing combines two sealed air cavities filled with inert gas and a warm spacer, creating an effective acoustic barrier that keeps your home peaceful.

The HF510 Home Pure is custom-sized and installed to match your exact window opening dimensions and geometry. Internorm ensures each frame is manufactured to strict tolerances and installed by certified professionals, guaranteeing perfect sealing and maximum long-term performance.

The wood interior requires light annual maintenance — cleaning and occasional resealing every 4–6 years. The exterior aluminium is virtually maintenance-free and weather-resistant. With proper care, an Internorm HF510 lasts 50+ years while maintaining full thermal performance and flawless operation.
