The 80mm Sliding Window & Door Series provides a compact yet capable solution for projects that require efficient thermal performance and smooth sliding operation in a more streamlined profile. Its multi-chamber design reduces thermal conductivity, supporting energy savings and consistent indoor comfort. The sliding mechanism is engineered for easy operation, while the integrated weather seals and weep holes offer dependable water tightness. Sound insulation is achieved through precision-fitted joints and welded corners, creating a quieter indoor environment. Steel-reinforced frames contribute to security and structural stability, while the UPVC material is resistant to termites, corrosion, and the effects of harsh weather conditions. The smooth, closed surface is easy to clean and does not require painting. This series also offers high electrical insulation and resistance to airborne pollutants, making it a reliable option for urban and industrial environments. Environmentally, the 80mm series is lead-free, consumes less energy during production, and is fully recyclable, aligning with sustainable building practices.
