The 112mm Sliding Window & Door Series is engineered for large-scale openings where strength, thermal performance, and smooth functionality are paramount. Its wide multi-chamber profiles provide exceptional thermal insulation, reducing heat transfer and energy costs across both residential and commercial projects. The sliding mechanism is designed to deliver effortless operation while maintaining superior water tightness through integrated weep holes and weather seals. Sound insulation is optimized with tightly sealed joints and welded corners, ensuring quiet interiors even in busy urban settings. Security is reinforced with steel-reinforced frames, offering a high level of resistance against forced entry. This series also excels in weather resistance, maintaining its appearance and performance under harsh sunlight, heavy rain, and temperature fluctuations. The UPVC material is termite-proof, corrosion-resistant, and completely recyclable. Its low-maintenance surface can be cleaned with mild detergent, and its lead-free composition makes it an environmentally responsible choice for modern building projects.
