IMPORTANT - to All Sauna Builders:

Why Sauna-rated Lights are Mandatory!
Lights cannot be recessed into the ceiling. Pot lights are a poor choice - the electric code does not allow insulation around them. But the sauna ceiling must be well insulated! Use only sauna-rated light fixtures with heavy glass and several layers of gaskets - these sauna-rated lights are available on this website.

Why the Driest Cedar is Mandatory for Saunas!
In order to prevent shrinkage in the cedar during the next 2 years, the mandatory low moisture content of 9% from kiln-drying (curing) is absolutely necessary. T&G cedar boards from local lumber yards are not dry enough to meet this sauna requirement - gaps between the T&G boards will open up later as the T&G dries out slowly each time the sauna is used.
Our moisture content is an extremely low 9%. Our cedar is well-kiln dried to a low 9% moisture content by our cedar mill supplier - it is specifically for sauna building.

Why Aluminum Foil in Mandatory for the Vapor Barrier!
Polyethylene cannot be used
as it has no resistance to heat - it will slowly "evaporate" starting in the ceiling. Only aluminum foil will last indefinitely. It comes in a roll 50" wide for easy installation when attached to the studs.

Since 1974, we have been a top-level supplier of affordable sauna parts and components for traditional hot rock and steam saunas.
