Integral lift & slide doors, in short HSI, are the key to our Fineline facade system, combining style, functionality, and sustainability. Featuring a warm wooden core for an inviting interior and a durable aluminum exterior for maximum protection, they seamlessly blend beauty with practicality. High-quality, ballbearing roller bogies ensure smooth running, quiet as a whisper.
Designed for energy efficiency, HSI doors typically include triple-pane insulated glass with an impressive Ug-value of 0.5 W/(m²K). This ensures superior thermal insulation, reducing heating costs and minimizing CO2 emissions by keeping warmth in during winter and heat out in summer.
The barrier-free construction of FineLine by UNILUX creates a nearly imperceptible threshold, merging interior flooring with patio decking into a unified living space. Indoors and outdoors flow together harmoniously, elevating both aesthetics and functionality.
