Realistic photo inside a residential attic, looking toward a wood gable wall with a louvered vent. Two parallel rigid galvanized metal round ducts run horizontally on top of ceiling joists toward the gable wall, one 4-inch diameter and one 6-inch diameter spaced 15 inches apart. Each duct has two 45-degree elbows near the left end where they connect to exhaust fan housings mounted in the ceiling below. The ducts are secured with metal hanger straps. The attic has wooden rafters and no insulation yet. Warm overhead work light illumination. Technical, realistic, DIY home improvement style. Mehr sehen
