Picture Windows: These windows are fixed and do not open. They provide unobstructed views and maximum natural light. Often combined with other window types for ventilation.
Bay Windows: These windows project outward from the wall, creating a small alcove inside. They consist of a central picture window flanked by two angled windows (usually casement or double-hung).
Bow Windows: Similar to bay windows, but they are curved rather than angled. They create a more rounded appearance.
Specialty Windows: These windows come in various shapes and sizes, such as round, oval, or arched. They are often used to add architectural interest to a home.

Window Frame Materials

The frame material of your windows also plays a significant role in their performance, durability, and aesthetics. Here are some common window frame materials:

Vinyl: Vinyl windows are a popular choice due to their affordability, energy efficiency, and low maintenance. They are resistant to rot, insects, and moisture. However, they may not be as aesthetically appealing as other materials. Very common in North America and Europe.
Wood: Wood windows offer a classic, natural look and excellent insulation. However, they require regular maintenance, such as painting or staining, to prevent rot and insect damage. Historically popular, now often seen in high-end homes.
Aluminum: Aluminum windows are strong and durable, but they are not as energy-efficient as other materials. They are often used in commercial buildings and coastal areas due to their resistance to corrosion.
Fiberglass: Fiberglass windows are strong, durable, and energy-efficient. They are also resistant to rot, insects, and moisture. They can be painted or stained to match any décor. A premium option with excellent longevity.
Composite: Composite windows are made from a combination of materials, such as wood fibers and plastics. They offer a good balance of durability, energy efficiency, and aesthetics.

The Window Installation Process

The window installation process typically involves the following steps:

Measurement and Ordering: Accurate measurements are crucial for ensuring that your new windows fit properly. A professional window installer will take precise measurements of your existing window openings. Based on these measurements, the windows will be custom-ordered from the manufacturer.
Preparation: Before installation begins, the installer will prepare the work area by covering furniture and floors to protect them from dust and debris. They will also remove the old windows.
Installation: The installer will carefully place the new window into the opening, ensuring that it is level and plumb. They will then secure the window frame to the wall using screws or nails.
Insulation and Sealing: Proper insulation and sealing are essential for preventing air and water leaks. The installer will fill any gaps around the window frame with insulation and apply sealant to create a watertight seal.
Finishing Touches: The installer will then install any trim or molding around the window to provide a finished look. They will also clean up the work area and dispose of the old windows.

DIY vs. Professional Window Installation

While some homeowners may be tempted to install windows themselves, it's generally recommended to hire a professional window installer. Window installation requires specialized skills and tools, and improper installation can lead to a variety of problems, such as air and water leaks, structural damage, and reduced energy efficiency.
