Kingspan Sauna Satu (previously SPU Sauna Satu) is designed specifically for insulating the walls and ceilings of a sauna, as well as the roof surfaces of wet rooms.

Kingspan Sauna Satu is made of a lightweight thermally stable polyurethane board. Thanks to its excellent insulation capacity, the thickness of insulation needed in a stone wall, for instance, is half of the amount needed compared to Rockwool, the aluminium paper surface also reflects back some heat radiation improving the overall heat insulation capacity of the sauna structure.

The Kingspan sauna insulation boards are easy to work with, they can be cut, milled, drilled and nailed and have full tongue-and-groove edging all around, quick to fit, lightweight and easy to handle even in confined spaces. Kingspan sauna satu is perfect for saunas with both stone and timber structures.

Kingspan Sauna Satu insulation boards stop mould damage by preventing water from penetrating the wall and ceiling structure, a complete water seal can be achieved by using sealing tape on joints together with joint glue.

The sauna insulation boards do not shrink, decay, and are specifically designed to withstand hot and humid conditions extremely well. Using Kingspan Sauna Satu you can seal out humidity and heat from the structure allowing your bespoke sauna to heat up safely and efficiently, the sauna insulation can withstand continuous temperatures of +100oC.

These should be used in preference to traditional PIR insulation boards which will degrade at the temperatures present in most saunas. When traditional PIR boards thermally degrade, they can release hydrogen cyanide so it's important to use this specific sauna insulation board in sauna construction.

Moisture safety

Kingspan Sauna-Satu insulation is not hydrogen, shrink, rot or mould. However, the structures must always be handled with care if the structures are exposed to moisture.

Fire retardant properties

Kingspan insulated solutions meet their fire regulations. In the event of a fire, Kingspan Sauna-Satu insulation is slowly charred, whereby the carbonated layer slows down the penetration of the fire in the insulation layer. 

Water vapour resistance

The water vapour resistance of the Kingspan Sauna-Satu insulation with aluminium laminate surface is many times higher than the 0.2 mm plastic film. There is no need for a separate vapour barrier when using Kingspan Sauna-Satu insulation.
