As modern frame apertures expand, there’s a growing demand for larger glass areas with fewer vertical divisions by frame members. Delight Windows’ Heavy Duty Patio Doors meet these new challenges with their 2-pane version, capable of being manufactured up to 5.8 meters wide and 3.0 meters tall, supporting a maximum sash weight of 300 kg. Our skilled employees and fabricators are dedicated to crafting the best heavy-duty patio doors in India. The overall outer frame depth of 142 mm, housing two 62 mm deep sashes, is ideal for modern straight-through apertures. Smooth operation of the heavy sashes is ensured by using tandem rollers with a high weight-carrying capacity, combined with Delight Windows’ robust aluminum threshold construction and a sturdy D-handle, securely anchored into the concealed sash steel.
