The Weru Alegra sliding door combines outstanding operating comfort with advanced engineering, making it an ideal solution for large openings where space-saving design is essential. Its precision-guided sash, supported at both the top and bottom, ensures exceptionally smooth, quiet, and effortless operation every time.
Designed to accommodate expansive glazed areas, the system can support sash weights of up to 400kg, making it perfectly suited for creating wide, uninterrupted views and light-filled living spaces. Optional features such as a soft-close function further enhance ease of use, adding a refined and controlled closing action.
Performance is at the heart of the Alegra system. High-tech multi-chamber profiles deliver excellent thermal insulation, achieving ultra-low U-values while helping to regulate solar gain—keeping interiors cooler in summer and warmer in winter. The door also offers impressive air tightness, structural stability, and outstanding resistance to wind and weather, alongside advanced multi-point locking systems for enhanced security and peace of mind. It meets stringent German energy efficiency standards, aligning closely with evolving UK requirements.
A low, flush threshold design improves accessibility while maintaining excellent weather sealing and energy efficiency. This barrier-free option eliminates awkward step-overs, making it ideal for modern living, families, and wheelchair access, while creating a seamless transition between indoor and outdoor spaces.
The innovative PVCu-aluminium construction combines the thermal efficiency of PVCu internally with the strength and durability of aluminium externally, resulting in a system that is both robust and low maintenance. A wide choice of colours, finishes, and configurations allows for complete design flexibility, ensuring the door complements any style of property.
In addition, the advanced profile construction supports glazing thicknesses of up to 53mm, enhancing thermal performance, acoustic insulation, and security. This makes the Alegra sliding door a versatile solution for a wide range of environments—from exposed coastal properties to busy urban settings—delivering comfort, performance, and style all year round.
