About R-Value
SEED wall panels, as well as roof and floor panels, can be adjusted to meet your desired R-Value.
Most commonly, wall panels include a 7-inch exterior cavity filled with dense-packed cellulose insulation. This results in an R-Value of R50 when combined with natural insulation in the interior cavity and wood fibre board exterior continuous insulation.
