Description
The ETNA Thermo Aspen sauna door by Andres Glass Solutions is an insulated, double-glazed door for saunas where energy efficiency matters as much as design. Its frame is thermal aspen: knot-free, 92 mm deep and finger jointed with the joints hidden from view, a timber prized for its resistance to moisture and temperature swings. The double-glazed pane helps prevent condensation, while the thermal aspen frame reduces heat loss and helps the sauna hold its optimum temperature for longer. The 8 mm clear toughened glass hangs on hidden hinges, a threshold is included as standard, and the door arrives fully assembled in 7 × 19 (700 × 1900 mm) or 7 × 20 (700 × 2000 mm) sizes.
