After 30 years, it was time for an upgrade of the doors at Aston at The Whaler at Kaanapali Beach in Lahaina, Hawaii. Aston Hotels & Resorts turned to Western Window Systems to replace the sliding doors in all 410 units in two 12-floor towers of the resort. The new Series 600 Sliding Doors, each with a white painted finish, are insulated, low-E glass doors that allow for energy efficiency. The biggest doors (184 by 99 inches) were installed by Glass Products Hawaii in 215 units, while 120 units now benefit from 160-by-99-inch sliders.
