Timber-Alu: Strength, Style, and Sustainability

The Internorm HF 510 sets a new benchmark in timber-aluminium window design, combining exceptional stability, advanced thermal and acoustic performance, and a refined, minimalist aesthetic.

The HF 510 features a high-performance timber-aluminium construction that delivers strength, durability, and a refined aesthetic. A composite combination of a solid timber interior, insulating foam core, and robust aluminium cladding ensures long-term structural integrity and outstanding energy performance.

Thermal performance is a core benefit, with Uw values of up to 0.65 W/m²K, supported by Internorm’s I-tec Glazing—a system that bonds the glass pane all the way around the frame for improved stability, insulation, and energy efficiency.

The HF 510 also delivers excellent sound reduction, offering acoustic insulation from 35 dB to 47 dB depending on the chosen glazing—ideal for urban homes or noise-sensitive environments.

Security features include a fully concealed locking system and security ratings of up to RC1N and RC2, offering discreet yet highly effective protection.

Designed for long-term durability and visual harmony, the HF 510 offers a range of sustainably sourced timber options, paired with extensive colour and finish choices to suit any interior. Every element is crafted to meet high design expectations while supporting low-energy building goals.

Internorm’s commitment to sustainability is built into the HF 510. It comes standard with low-carbon iplus glass, reducing CO₂ emissions by approximately 10,000 tonnes annually across the Internorm product range. By using recycled materials, low-emission raw inputs, and energy-efficient manufacturing, the HF 510 reflects a conscious approach to innovation—one that benefits both homes and the planet.
