Specialty Window Types

There are also several specialty window types. We’ve detailed them below.

• Arched windows: Also called half-moon windows, arched windows are rectangular with a rounded semi-circle at the top. They let more natural light into your home and offer a timeless look.
• Custom windows: Custom windows can fit practically any size or shape. They’re a great option if you have a space where you want windows, but standard sizes won’t fit.
• Egress windows: Egress windows are designed to open easily and are legally required in bedrooms, basements, and habitable attics as an emergency exit in the event of a fire or another disaster. Egress windows on average cost $3,500.
• Hopper windows: Hopper windows are similar to awning windows. However, they open inwards from the top rather than outwards from the bottom.
• Garden windows: Garden windows can cost between $1,500 and $5,000 and protrude from an exterior wall, similar to a bay window. They’re often installed above a kitchen sink and provide a shelf to put plants, acting like a mini greenhouse.
• Glass block windows: Glass block windows are common in basements and bathrooms. They’re made of thick glass blocks that are translucent but not clear, providing privacy and security while allowing light in.
• Jalousie windows: Jalousie windows are made of glass slats set into a frame. They were designed to provide venting in humid climates and can be opened and adjusted like blinds to control airflow.
• Shaped windows: Shaped windows are essentially picture windows that aren’t rectangular. They’re generally meant to add architectural detail and don’t open.

Energy-Efficient Windows

Many window brands offer energy-efficient options. Replacing your windows with energy-efficient windows can reduce your carbon footprint, maintain your home’s temperature, and help you save money on your electricity bills.

Energy Star-certified windows can save you up to 12% on your power bills. These windows also qualify you for the Windows and Skylights Tax Credit, which provides a tax credit equal to up to 30% of your project’s cost (or a $600 maximum).

We’ve detailed some other energy efficiency features to consider below:

• Argon gas: Many window manufacturers fill the space between glass panes with this odorless, colorless, and nontoxic gas. Argon gas is denser than air, so it insulates against the elements and heat exchange. This helps to preserve your home’s internal temperature and decrease energy bills.
• Low-emissivity (low-e) coating: This is a thin, invisible metallic coating that window manufacturers place on the inner part of the window’s exterior pane. This prevents heat from escaping your home during winter and keeps heat outside during summer. The coating also protects your interior and furniture from fading and sun damage.
• Multipane glass: Double-pane and triple-pane windows both block more heat than single-pane windows. They also offer insulation and soundproofing.  
• Warm edge spacer: This spacer creates a seal around your window’s glass panes and frame. It also insulates the window and reduces heat transfer.
• Weatherstripping: Many windows manufacturers design windows with weatherstripping because it creates a tight seal that keeps drafts out. We suggest looking for high-quality weatherstripping that includes fibrous materials, such as plastic or metal.

When To Replace Your Windows

If you notice any of these signs, it may be time to replace your windows.

• Cold glass or drafts: Your windows might not be insulating properly if you feel a draft or the glass is cold. 
• Condensation buildup: Condensation buildup indicates damage to the seals. Excess condensation can lead to problems such as mold and mildew, so it’s best to address this issue quickly. Though seals can sometimes be replaced, this problem often requires total window replacement.
• Damage: Visible damage is a common reason for window replacement. You might be able to get by with simply repairing a cracked window, but it’s best to prepare for window replacement if there’s extensive damage.
• Decreased functionality: If it’s become more difficult to open or close your windows, something may be broken. It could be faulty hardware that’s easily remediated, or it could be that a component needs replacement.
• Increased utility bills: If your windows aren’t working properly, your heating and cooling system will work overtime to keep a consistent temperature, leading to higher utility bills.
