Exterior walls

The 1WallS are used for exterior and interior walls. Widths come in 6 in. or 12 in. options with respective “R” factors of R30-R50.  When our MULTICERAMIC thermal coatings are added the”R” factors double to R60-R100 respectively.  To save time and money, almost any siding can be directly applied to the 1WallS reducing time, labor and costly multi-step processes.
