The Layers of a Custom Sauna

  1. Framing – It is the fitting together of pieces to give structure, support, and shape. Headers are built over windows and doors to support the roof load.
  2. Furring strips – These are used to separate the wood paneling from the exterior wall, to give an air gap for the space to breathe. It helps to dry the wood and is crucial for reflecting the heat back into the room.
  3. Foil Vapor Barrier – This is applied over the framing in the hot room areas. It serves as a vapor barrier to the exterior while also reflecting the heat back inside the room.
  4. Wall Paneling – Commonly used as cedar T&G, but many different forms of paneling can be used. This is the outer layer of the interior, which is a wood that can soak up steam and deal with heat absorption without any type of long-term damage. It is also highly resistant to fungus, rot, and decay.
  5. Sheathing – 7/16″ OSB sheathing applied over the framing, which holds everything together and prevents the building from ever swaying or bending. It’s used as a nailing base for your siding materials as well.
  6. Insulation – This is the unit’s insulation. It’s a standard fiberglass insulating material and works to trap air and slow the transfer of heat.
  7. Maintenance-free siding – This is the outer layer of the structure. It’s a fully waterproof, maintenance-free siding option and is available in many different colors/styles.
  8. Breathable Membrane – This is a breathable, water-resistant membrane made to resist moisture and release water vapor and works as an air barrier to the structure.

Things to Understand About Layering

Every wall component plays a crucial part in the build process. But…. they work together, not by themselves.

What do we mean by that? Let us explain..

  1. For the vapor barrier to work, the insulation has to be installed. Without insulation, you will create a moisture trap and rot out the wood. The space needs to be a space that doesn’t let air move through, and it is crucial to make sure your insulation fills the entire framing cavity.
  2. If you are using a vapor barrier, you must ensure that you use unfaced insulation. You NEVER want a double vapor barrier, as it will trap moisture between the layers. All the components installed in the right order will work seamlessly to ensure your building stays dry, ventilates, and is free from moisture and heat loss.
  3. Your vapor barrier has to be 100% sealed on all seams, edges, and cuts in order for it to work correctly. In a sauna, furring strips behind the cedar are highly recommended to help the cedar stay dry and ensure that the reflective vapor barrier will work correctly. Without an air gap, the foil vapor barrier does not work as it should.
  4. Always install a wood material that is rated for sauna use.
