Fixed Window Advantages
Fixed frame windows offer two significant advantages over movable windows. One, they get better energy efficiency numbers than comparable casements, single hungs, and other movable windows. Because they don't open, there is very little way for the air and outside elements to get through (poor seals or improper installation being the exceptions). Two, fixed frames have less parts and components, which limits the amount of repairs and issues that can occur over the life of the window. This is nice peace of mind for consumers who understandably worry about the cost and hassle of replacing home windows when something does go wrong.
