The HF 510 timber aluminium window system features a beautifully crafted timber interior that brings warmth and natural character to living spaces. Available in a range of high-quality timber finishes, the interior surface can be tailored to suit both traditional and contemporary interiors.
The natural properties of timber also contribute to improved comfort and excellent thermal insulation, helping create a pleasant indoor climate.
Externally, the HF 510 is protected by a robust aluminium cladding that shields the timber frame from weather exposure. This aluminium layer requires minimal maintenance and ensures long-term durability while maintaining the clean, modern look expected from premium timber aluminium windows.
A wide range of powder-coated colours allows architects and homeowners to match the windows with any façade design.
Energy efficiency is a key feature of the HF 510 timber aluminium profile. With advanced triple glazing and innovative frame construction, these timber-aluminium windows deliver exceptional thermal insulation.
With U-values as low as 0.65 W/m²K, the HF 510 is suitable for low-energy homes and demanding architectural projects where performance and comfort are essential.
The HF 510 incorporates Internorm’s innovative technologies, such as I-tec Glazing and I-tec Core, enhancing the stability and strength of the window construction.
Bonding the glass pane to the sash improves overall rigidity and security while allowing for larger glazing areas and slimmer frames.
The HF 510 timber aluminium window system also delivers excellent acoustic insulation. With sound reduction of up to 43 dB, these timber aluminium windows help create quieter interior spaces by significantly reducing external noise.
This makes them ideal for properties located in busy urban environments or near roads and transport routes.
The tilt-and-turn mechanism features fully concealed locking hardware, giving the HF 510 a clean, elegant appearance. Hidden hinges and locks improve both aesthetics and security while allowing the slim frame profile to remain the visual focus.
Large glass areas allow more natural light to enter the building, enhancing interior spaces and architectural design.
Internorm HF 510 timber aluminium windows are available in a wide range of colours and finishes, allowing complete design flexibility for both modern and traditional architecture.
The durable aluminium exterior can be powder-coated in a broad selection of contemporary colours, textured finishes, and metallic shades. This weather-resistant coating ensures long-lasting protection while maintaining the clean, architectural appearance of premium timber aluminium windows.
Internorm also offers a variety of interior timber finishes, allowing the natural beauty of wood to complement your interior design. Whether you prefer light natural tones or darker stained finishes, the HF 510 system provides options to suit every style.
These customisation options make the HF 510 timber aluminium system suitable for a wide range of residential and commercial architectural projects.
The interior of the HF 510 timber-aluminium window system is crafted from sustainably sourced timber, bringing natural warmth and character to the home.
