What makes the H3 window a standout choice is its remarkable versatility. Whether you’re craving unobstructed views of a lush garden, need to maximize floor space in a compact room, or want precise control over airflow, this window delivers. Its signature tilt-and-slide mechanism combines two essential functions: a smooth horizontal slide that eliminates protruding sashes (perfect for tight spaces like balconies or hallways) and an inward tilt feature with a 115mm controlled opening for safe, micro-ventilation. This means you can enjoy fresh air even during light showers or when stepping out briefly, without compromising security.
The invisible track design adds a touch of understated luxury, creating a seamless look that blends effortlessly with modern, minimalist, or classic interiors. For those seeking a dramatic visual impact, mullion-free floor-to-ceiling configurations turn walls into panoramic vistas, flooding rooms with natural light and blurring the line between indoors and out.
Beyond versatility, the H3 window prioritizes safety and convenience. Its inward-opening high-density alloy mesh screen—featuring 0.4mm ultra-fine pores—provides 360° protection against insects while preserving clear views. For larger sashes (≥1600mm in height), a reinforced middle mullion ensures the screen remains sturdy even with frequent use, making it ideal for family homes or commercial spaces.
At the heart of the H3 window lies the German WEHAG hardware system, a symbol of durability and performance. The base-free handles and six-point locking mechanism operate with whisper-quiet smoothness, thanks to ±5mm micro-adjustable components that minimize friction. With a 100kg maximum sash load capacity, this system supports larger configurations without sacrificing stability. Corrosion-resistant aluminum alloy handles and continuous triple-seal strips (made from high-grade EPDM) enhance weather resistance, making the window suitable for coastal areas, busy cities, or humid climates.
Energy efficiency is a standout feature of the H3 window, thanks to its five-seal thermal insulation technology. A staggered 5-layer seal design creates two distinct chambers: an outer water-resistant cavity with a 75mm high waterproof track and angled drainage (to prevent water buildup) and an inner air-tight cavity with a PA66GF25 thermal break strip (24mm sash + 35mm frame). Paired with 27A acoustic glass (available in 37mm or 39mm options), this design reduces external noise by 35dB—enough to muffle street traffic or loud neighbors—and cuts energy costs by 40%, keeping interiors cooler in summer and warmer in winter. Dual-color thermal break profiles add to its appeal, balancing outdoor UV resistance with indoor style.

Crafted from aerospace-grade aluminum with ±0.2mm precision tolerance, the H3 window offers extensive customization to match your project’s unique needs. Choose from 4 fade-resistant fluorocarbon finishes to complement exterior facades or interior decor. For larger installations, reinforced mid-rails ensure stability for sashes ≥1600mm, while anti-collision sills and open drainage (with a 20% larger flow area) enhance durability in harsh weather conditions—from coastal salt spray to heavy rainfall.
