Nordic Structural Engineering

Cross-Laminated Timber Structure

The Leil® Celto sauna is constructed from cross-laminated timber (CLT), an advanced structural material made by bonding layers of solid wood at alternating angles. This creates a strong, stable, and durable structure with a modern architectural finish designed to perform in demanding sauna environments.

Thermal Performance

Solid 60 mm Timber Walls

Thick 60 mm CLT wall panels provide excellent thermal performance, helping the sauna heat efficiently and retain warmth during use. The dense timber construction improves energy efficiency while maintaining a stable and comfortable sauna environment.

Long-Term Flexibility

Relocatable Timber Construction

Designed with adaptability in mind, the CLT panel system allows the sauna to be carefully disassembled and reassembled when required. This makes the Leil® Celto ideal for relocations, renovations, or changing outdoor spaces.

Smart Modular Design

Quick Assembly System

The Leil® Celto sauna features a precision-engineered panel system designed for straightforward installation using standard tools. The modular construction simplifies assembly while maintaining the strength and integrity of the finished sauna.

Natural Timber Finish

Customisable Timber Surfaces

The unfinished timber surfaces provide complete design flexibility, allowing the sauna to be customised with oils, stains, or paints to suit your preferred aesthetic. This allows the natural character of the timber to be enhanced while creating a finish that complements your surrounding environment.
