Product Highlights
Parsol Dark Grey Thermal Glass Front
The expansive single-glazed glass front is framed in black aluminum and engineered to reduce solar heat gain while maintaining clear sightlines. It gives the cabin a clean, architectural presence in any outdoor setting.
STEICO Wood Fiber Insulation
Multi-layer STEICO insulation lines the walls and ceiling to retain interior heat effectively. This reduces energy consumption and helps the cabin reach and hold target temperatures consistently.
Thermo Aspen Benches & Backrests
Interior seating is crafted from thermo aspen, a heat-treated wood that resists warping and remains comfortable to the touch during sessions. The smooth finish is easy to maintain.
Thermally Modified Tyrol Wood Exterior
The exterior cladding features a textured grain finish that resists moisture and dimensional changes caused by weather exposure. It requires minimal maintenance compared to untreated wood.
Firestone EPDM Roof
The flat roof is finished with a Firestone EPDM membrane, a commercial-grade material known for weather resistance and long service life in outdoor installations.
Integrated RGB LED Lighting
Built-in color-adjustable LED lighting allows you to set the tone for each session. The system is pre-wired and ready to use upon delivery.
Fully Assembled & Pre-Wired
The Spectra ships as a complete unit. Electrical components are pre-wired, and the structure requires no on-site assembly, reducing setup time significantly.
