Product Details
DERCHI’s sliding doors combine thermally broken aluminum profiles with double or triple glazing, Low-E coatings, and EPDM seals. For the Q15 series, U-values reach 0.28 U.S./I-P. Track choices—two-track, three-track, lift-slide, concealed—handle panels up to 4000 mm wide and 6000 mm high. Heavy-duty rollers, multi-point locks, and anti-typhoon wheels provide reliable operation in high-rise and coastal settings. Pre-assembled options help volume installers cut on-site labor.
