Larger diameter pipes can be accommodated with the J. Journault's Pipe Box. Available in any size or height, it is ideal where numerous pipes and lines must penetrate the roof through one large opening. The box and cover are fully insulated to prevent any condensation.

Options
Height additions, heavier metal gauges, steel liners, construction to match roof pitch, thick rigid fiberglass insulation or variable insulation thickness, special sizes or beveled wood nailers.
