Walls and Ceiling
Existing brick or masonry walls are lined with horizontal timber battens; existing stud walls are incorporated unchanged except for extra studs or noggins added as required. Ceiling joists are installed for a finished ceiling height of 2100, or at maximum 2400 mm.

Insulation batts R1.5 grade are installed between battens and studs, and a double layer of same between ceiling joists.

The insulated walls and ceiling are lined with aluminium foil, and then with cedar panelling using a secret-nail profile. Panelling thickness may be 10 mm or 15 mm.

Floor
We recommend non-slip tiles or similar. "Duckboards" made from cedar decking slats are optional. Floor waste is required if there is a tap in the sauna; and is recommended for steam-sauna.

Domestic sauna seats are of cedar decking slats on cedar frames.

Commercial sauna seats are of 40 mm thick cedar beams on cedar frame supports.

A high bench is usually 900 mm high and a low bench 450 mm, but may vary for special layouts. Back rails are installed above the high bench.

Sauna door is cedar framed, insulated, cedar panelled both sides, with observation window approx 260 x 600 mm, and cedar jamb. Other window sizes are available, also door of full length glass in cedar frame. Commercial saunas have a door closer.

Tylo equipment and accessories include the heater, sauna stones, bucket and ladle, thermometer, light fitting. Extras: hygrometer, sand timer, head/back rest.

Ventilation:
Generally a 20-25 mm door undercut serves as fresh air intake, an outlet vent is installed opposite the heater at approx 1800 off the floor, has an adjustable cover, and may be connected to a ducter air exhaust.
Some larger saunas may require mechanical ventilation.

Power for Lights:
Lights are usually on the general supply, eg the gym or the pool area etc, but switched independently for maintenance.

Power for Heaters:
Heater size depends on the room volume (cubic metres)
