What is a Double Hung Window? Everything You Need to Know

June 20, 2023

Double hung windows are a popular choice for homeowners looking for a versatile and efficient window option. To better understand deep into the world of these popular windows, let’s examine their unique features, benefits, and parts.

What is a Double Hung Window?

A double hung window consists of two vertically stacked sashes that can be opened and closed independently. This design allows for improved airflow and easier cleaning, as both the top and bottom sashes can be tilted inwards. The versatility of a double hung window makes them an attractive option for homeowners and builders alike.

Parts of a Double Hung

To better understand the double hung window, let’s explore its key components:

  1. Sashes: The top and bottom sashes are the movable parts of a double hung, which can be raised, lowered, or tilted inward for cleaning.
  2. Frame: The frame provides support and structure to the window and houses the sashes.
  3. Jambs: These are the vertical sides of the window frame, which hold the sashes in place.
  4. Sill: The horizontal base of the window frame, upon which the sashes rest when closed.
  5. Head: The horizontal top of the window frame.
  6. Tilt Latches: Small mechanisms located on the top of the bottom sash and the bottom of the top sash, which allow the sashes to be tilted inward for cleaning.
  7. Lock: The locking mechanism that secures the sashes in place when the window is closed.
  8. Weatherstripping: Material that helps seal the window, preventing drafts and improving energy efficiency.
  9. Glazing: The glass panes within the sashes, which can be single, double, or even triple glazed for improved insulation.

Benefits of Double Hungs

Double hung windows offer numerous advantages for homeowners. Some of the key benefits include:

  1. Improved Ventilation: With both the top and bottom sashes operable, double hung windows provide enhanced airflow, allowing for more efficient cooling of your living space.
  2. Easy Cleaning: The tilt-in sashes make cleaning the interior and exterior glass a breeze, even on second or third-floor windows.
  3. Energy Efficiency: Double hungs often feature double or triple glazing and weatherstripping, which help to reduce drafts and improve insulation.
  4. Versatility: These windows are available in a variety of styles, materials, and sizes, making them suitable for virtually any home design.
  5. Security: The locking mechanism and sturdy frame construction provide increased security compared to other window types.

Double Hung Windows vs. Single Hung Windows

While double hung windows have two operable sashes, single hung windows feature a fixed upper sash and an operable bottom sash. This design difference results in some key distinctions between the two window types:

  • Ventilation: Single hung windows offer less airflow, as only the bottom sash can be opened.
  • Cleaning: The fixed upper sash on single hung windows makes exterior cleaning more challenging, especially for windows on higher floors.
  • Flexibility: Double hungs provide more versatile ventilation options, as both the top and bottom sashes can be opened to suit your needs.

Ideal Candidates for Double Hungs

Double hung windows are a great choice for a wide range of homeowners, but they may be particularly advantageous for those with:

  • Multi-story homes: The easy-to-clean tilt-in sashes make double hungs an excellent choice for second and third-floor windows.
  • Children or pets: The ability to open only the top sash can provide ventilation while keeping children and pets safely inside.
  • Historic homes: Double hung windows have a classic design that complements traditional architectural styles.
  • Energy-conscious homeowners: The enhanced energy efficiency of double hungs can help reduce heating and cooling costs.

Cleaning and Maintaining Double Hung Windows

To keep your windows in top condition, follow these simple cleaning and maintenance tips:

  1. Routine Cleaning: Remove dirt and debris from the window sashes, tracks, and frame with a soft brush or vacuum attachment. Wipe down surfaces with a damp cloth and mild detergent.
  2. Glass Cleaning: For streak-free glass, use a glass cleaner and a microfiber cloth to clean both the interior and exterior panes. Remember to tilt the sashes inward for easy access to the exterior glass.
  3. Lubrication: Apply a silicone-based lubricant to the tracks and other moving parts to ensure smooth operation.
  4. Weatherstripping: Periodically inspect and replace worn weatherstripping to maintain optimal energy efficiency.
  5. Hardware: Check and tighten any loose screws or hardware to keep your window secure and functional.
