Bark House Poplar Panels are one of the most extraordinary products that we offer. We estimate that no more than one in a hundred trees will yield a sheet of bark large enough to become one of these treasures. Harvested in the same manner as our shingles, timing and skill are critical to the success of unrolling an unbroken full cylinder from a log. No two are ever alike. Limb scars, epicormic knots, growth stress, bird peck, and lightning scars are all textural variances that can be present that give each sheet its own unique identity. One can even tell directions the bark faced by the distinct color changes that flow from the north side to the south.
