Double-Hung Windows

The double-hung window is the most popular of all home window types. Modern double-hung windows have an operable upper and lower sash that allows each to slide vertically within the window frame. Their classic style fits well with many home designs, and they’re easy to clean, maintain, and operate.

Single-Hung Windows

The single-hung window is similar to the double-hung window; however, single-hung windows have only one sash instead of two.

Sliding Windows

Sliding windows are a go-to window style for contemporary or modern homes. Sliding windows maximize ventilation and are optimal in small spaces because they open horizontally via a sliding track.

Casement and Awning Windows

Ideal for hard-to-reach areas, casement windows open outward with hinges along one side, much like a door. Conversely, awning windows open outward from the bottom and have hinges at the top of the window. Casement and awning style windows offer benefits from their tight seals. Plus, they provide excellent ventilation and are very energy efficient.

How to Choose the Right Windows for Your Home

From your budget and local weather to your home's architectural design, there’s a lot to think about. Here’s what to consider as you’re choosing the right replacement windows for your home:

  • Room Functionality: Start by assessing each room’s needs. Easy-to-open windows work if you want fresh air in the kitchen, privacy glass is smart for bathrooms on busy roads, and expansive casement windows let in tons of light in high-traffic living areas.
  • Local Climate: When it comes to energy efficiency, your local weather is an important factor. For instance, those in warmer areas may opt for replacement windows with a low Solar Heat Gain Coefficient (SHGC) and a low U-factor to minimize heat transfer. Ask window professionals about what’s appropriate for your area.
  • Home Style: The style and design of your home truly matters when choosing the best replacement windows. Whether traditional, modern, historical, or contemporary, there are countless window styles to match your home’s architectural style and design.

Choosing the Best Window Materials for Your Home

Here are some advantages and disadvantages of different types of window frame materials:

Aluminum Window Frames

While not as energy efficient as other materials, aluminum window frames are strong and lightweight.

Fiberglass Window Frames

Fiberglass window frames may be costly, but they’re durable and extremely energy efficient.

Composite Window Frames

This popular window frame material is more expensive than others but offers enhanced performance for your property.

Vinyl Window Frames

Affordable and low-maintenance, vinyl window frames aren’t as durable as other materials, but are cost-effective.

Wood Window Frames

Beautiful and traditional, wood window frames are gorgeous, but they require constant upkeep and maintenance. Due to this, window manufacturers sell wood window frames covered in aluminum for less maintenance and greater durability.

When to Replace Home Windows

There are a few telltale signs that indicate when to replace home windows, including:

  • Air Drafts: Drafts around the window frames indicate that seals are likely failing and a replacement is needed.
  • Increase in Energy Bills: Poor insulation from old windows can cause your HVAC system to work harder, so you may see an increase in energy bills.
  • Fog or Condensation: Trapped condensation or a cloudy film on the window glass also points to a possible seal failure.
  • Difficulty Operating: Home windows can be difficult to open, close, and lock due to warped window frames or worn-out tracks.
  • Visible Damage: Cracks in the glass and material deterioration are signs that you may need replacement windows for your home.

Home Window Maintenance Tips

Proper maintenance is key to ensuring your new windows look good and last over the years. This is how to maintain the windows in your home:

1. Do regular inspections.

Inspect windows regularly. Examine the window glass, sash, and frame. Also, note any condensation, ensure the window opens correctly, and feel for drafts.

2. Seal gaps.

Seal gaps in your windows with spray foam insulation or caulk for more energy efficiency and to prevent water damage.

3. Keep windows clean. 

Wash the panes using a glass cleaner, a damp cloth for wood frames, and a mild detergent for other window frames.

4. Refresh windows often. 

As a general rule, home window frames should be repainted every three to four years to seal the wood.
