Custom Window Designs, a leader in innovative home solutions based in Markham, proudly showcases Single Hung Windows. This window design combines a traditional aesthetic with practical ventilation capabilities, making it an ideal choice for multi-room homes or residential buildings. While maintaining architectural integrity, it also caters to individual ventilation needs. Single Hung Tilt Windows are specifically crafted to fill large openings with their structural frame and sash. The bottom sash is the only part that operates, tilting inwards for easy exterior cleaning and allowing fresh air to enter. The upper portion of the window remains fixed, ensuring thermal efficiency. Experience the numerous benefits of our Single Hung Tilt Windows firsthand.


  • Tilt & Turn: The tilt-in sash design allows for easy cleaning from the inside, providing a convenient maintenance solution for homeowners.

  • Triple-Sealed Sashes: The windows feature triple-sealed sashes, along with a fin seal and pile, enhancing the sealing technology for improved energy efficiency and insulation.

  • Fibreglass Screen: To facilitate ventilation, the windows come with a full-sized fibreglass screen, allowing fresh air to enter while keeping insects out.

  • Snap-In Glazing: The snap-in glazing inside the windows facilitates easy glass replacement, simplifying maintenance tasks and ensuring longevity.

  • Elegant Contour Profile: The windows feature a new elegant contour profile, enhancing the overall aesthetic appeal and contributing to a sophisticated look.

  • Cost-Effective:

    Single hung windows are generally more affordable than their double hung counterparts, making them a cost-effective choice for budget-conscious homeowners.

  • Classic Appearance: They provide a classic and timeless appearance, fitting well with traditional architectural styles.
  • Energy Efficiency: When properly sealed, single hung windows can contribute to energy efficiency, helping to maintain a comfortable indoor temperature.
  • Structural Stability: The fixed upper sash adds structural stability, making them a durable option for large openings.
  • Ease of Operation: With only the bottom sash operational, single hung windows are straightforward to use, and their simplicity can be an advantage for some users.
  • Limited Ventilation:

    Compared to double hung or sliding windows, single hung windows offer limited ventilation options, as only the bottom sash is operable.

  • Cleaning Challenges: Exterior cleaning may be less convenient, as only the bottom sash tilts inwards. Cleaning the upper part may require exterior access.
  • Aesthetically Limited: While classic, the design of single hung windows may be considered less versatile and aesthetically limiting for homeowners seeking a more contemporary look.
  • Maintenance Concerns: Over time, the moving parts of the operational sash may be subject to wear and tear, potentially requiring maintenance.
  • Restricted Escape Route: In emergency situations, having only one operable sash may be a disadvantage as it restricts potential escape routes compared to windows with multiple operable sections.
  • Airflow Control: Limited control over airflow since only the bottom sash is operable, which may be a drawback for those who prefer more customized ventilation options.
