Cleveland Commercial replaced windows and doors in multiple units of this 16-story upscale high-rise condo building on Lake Erie. We used Pella's Casement and Awning windows, ideal for areas that need extra light and fresh air. For the patio, we used Pella's Sliding Patio Doors with Pella Impervia fiberglass products. The owner required engineering test reports to verify our products were able to meet the design pressure requirements, which Pella's Architectural Services department was able to provide the report. Pella Commercial updated many units that now have ENERGY STAR-certified windows while also giving the space a fresh look!
