The EPAL ES38 aluminium sliding system combines robustness and elegance, offering a reliable solution for medium and large openings. Designed to meet modern aesthetic and functional demands, the ES38 integrates seamlessly into any architectural environment.
The system features thermally broken profiles along their entire length, ensuring a high level of thermal insulation with a Uw coefficient starting from 2.9 W/(m²·K). The use of double or triple thermal insulating glass panes from leading manufacturers such as Guardian and Saint-Gobain achieves an insulation coefficient (Ug) of up to 0.7 W/(m²·K), providing comfort and energy efficiency.
The functionality of the EPAL ES38 is enhanced by stainless steel INOX guides and specialized mechanisms that support sash weights of up to 130 kg, ensuring smooth and safe operation. The system offers a wide range of configurations, such as overlapping and recessed windows, with the option of integrating insect screens or shutters, fully meeting the needs of any project.
The build quality of the EPAL ES38 is ensured through controlled production processes and the use of high-quality materials. The aluminium profiles are electrostatically painted at EPAL’s modern facility, guaranteeing durability and long-lasting performance.
