Explore Window Types
Understanding the differences between window styles is the first step in your replacement journey. Discover how each type works by hovering over the visual models below.
Casement Windows
Hinged at the side and open outward to the left or right like a door.
1How It Works
Operated via a crank, lever, or cam handle. The entire sash swings open on hinges attached to one side of the frame.
2Why People Choose Them
Ideal for hard-to-reach places (like over a kitchen sink) and locations where you want maximum ventilation.
Pros
- Excellent ventilation and airflow
- One of the most energy-efficient operable windows
- Unobstructed views with no center mullion
- Difficult to break into
Cons
- Cannot be used where they would swing into a walkway
- Screens must be placed on the inside
- Size is limited by the weight of the glass
Single & Double Hung
Classic vertical sliding windows with one (single) or two (double) operable sashes.
1How It Works
The sashes slide vertically in separate tracks. In a double-hung, both top and bottom move.
2Why People Choose Them
The most popular window style in North America due to their classic look and versatility.
Pros
- Space-saving design (does not project outwards)
- Easy to clean from the inside (many models tilt in)
- Versatile ventilation options
- Cost-effective due to high standardization
Cons
- Center meeting rail obstructs the view slightly
- Not as airtight as casement or picture windows
- Can be heavy to lift if not balanced properly
Tilt-and-Turn
European-style windows that can tilt inwards at the top or swing fully inward like a door.
1How It Works
Turning handle 90 degrees swings inward. Turning 180 degrees tilts top inward for secure ventilation.
2Why People Choose Them
Favored in modern and high-performance builds. Incredible security, superior soundproofing.
Pros
- Exceptional security even when tilted open
- Extremely high energy efficiency and airtightness
- Easy emergency egress and cleaning
- Premium, modern aesthetic
Cons
- More expensive than traditional North American styles
- Requires inward clearance for the swing function
- Window treatments require special mounting
Awning Windows
Hinged at the top and open outward from the bottom, creating an awning effect.
1How It Works
Similar to casements, they operate with a crank mechanism but push the bottom edge outward.
2Why People Choose Them
Perfect for leaving open during light rain. Often placed higher on walls for privacy.
Pros
- Can remain open during light rain without letting water in
- Excellent energy efficiency
- Provides good security when placed high on a wall
- Can be grouped with picture windows
Cons
- Project outward, obstructing exterior pathways
- Hard to clean the exterior from inside
- Limited egress capabilities
Hopper Windows
Hinged at the bottom and open inward from the top.
1How It Works
The reverse of an awning window. A latch releases the top, allowing it to tilt into the room.
2Why People Choose Them
Frequently used in basements and utility rooms where outward swing space is limited.
Pros
- Does not obstruct exterior landscaping or walkways
- Highly energy efficient and airtight
- Provides excellent ventilation for small spaces
- Easy to clean from the inside
Cons
- Interferes with interior space
- Leaves and debris can blow directly in if mounted low
- Not suitable for keeping open during rain
Slider / Glider
Horizontal sliding windows, functioning like a smaller sliding glass door.
1How It Works
One or both sashes glide horizontally along top and bottom tracks.
2Why People Choose Them
Ideal for wide openings where a casement would be too heavy. Great for contemporary homes.
Pros
- No swing space required inside or outside
- Very easy to operate
- Provides an unobstructed vertical view
- Durable with fewer mechanical parts to break
Cons
- Tracks can collect dirt, requiring regular cleaning
- Not as tightly sealed as casement windows
- Only half the window opening can be ventilated at a time
Picture / Fixed
Non-operable windows designed to frame a view and maximize natural light.
1How It Works
The glass is set permanently into the frame. There are no moving parts, hinges, or tracks.
2Why People Choose Them
Used when ventilation is not needed, but light and views are paramount.
Pros
- The most energy-efficient window type
- Provides the largest possible unobstructed view
- Extremely secure (cannot be opened)
- Cost-effective per square foot
Cons
- Provides absolutely zero ventilation
- Exterior must be cleaned from the outside
- Cannot be used for emergency egress
