LS-36™ Insulated Roof and Wall Panel

The LS-36™ insulated, exposed fastener metal wall and roof panel achieves unmatched insulation values. The panel provides versatility given its design options and functions as either a wall or roof for various commercial and industrial applications. The overlapping, through-fastened joint, paves the way for an efficient installation, resulting in reduced labor and energy costs. The panel can be used on the roof slopes as low as 1/2″:12″
