Think about reflected light
Water-facing rooms may experience changing glare throughout the day. Bring photos taken at the times the room is least comfortable and compare shading as well as glass options.
Match selection to each elevation
A shaded side elevation and an exposed view wall may benefit from different specifications. Ask how those choices affect exterior consistency and documented performance.
Plan for your property
A large picture window can frame a lake-facing outlook, while adjacent casements add ventilation. Plan access on sloped lots and check exterior detailing, water management, and association requirements before work begins.
