Fixed vs sliding windows
Fixed = largest view for lowest cost, but no ventilation. Sliding = wide horizontal opening that ventilates.
Fixed windows don't open; sliding windows do. Both common in modern and ranch architecture, often in the same room. The choice comes down to ventilation, cost, and what you want the window doing.

Fixed windows
Glass in a frame, no operating hardware. Cheapest per square foot of glass. Best seal — no gaskets or weatherstripping to fail. Largest unbroken view possible. Best for: picture windows, transoms, view walls where ventilation comes from elsewhere.
- 2
Sliding windows
Horizontal slider — one or more panels slide past each other on a track. Wider opening for the same wall height than a vertical slider. Ventilation through half the window's width at any time. Best for: bedrooms (egress), kitchens, bathrooms, modern/ranch architecture.

How to choose
Pick fixed if: the room has ventilation elsewhere, view is the point, budget is tight. Pick sliding if: the room needs egress, you want ventilation, or the architectural style calls for horizontal proportions.
Tips
Combine fixed and sliding in one wall
Large fixed center panel flanked by smaller sliding side panels. Maximizes view; provides ventilation.
