Arched & Triangled Window Treatment Solution – Custom Track & Curtain Quotation
Enhance the elegance of arched windows with our custom-made treatment solution, which includes both Made-to-measure Aluminum Tracks (available in straight or curved shape) and Customized Curtains tailored to your unique window shape. Whether your window has a gentle curve or a dramatic arch, we provide functional and aesthetic solutions that fit perfectly.

Each order requires a special quotation based on your measurements and installation needs. Please refer to our measurement guide photos and provide the required dimensions. Our team will work closely with you to ensure precision, durability, and a seamless fit.

  • Custom aluminum track (corded, top/side mount)
  • Support for straight and curved (arched) shapes
  • Matching curtains are available upon request
  • Track supports up to 13.2 lbs per meter

Pre-Measuring Note:

  • All measurements for arched windows should be taken based on the area to be covered. If your window has trims, moldings, or frames, please include their width and height so the final curtain and track can fully cover the intended space.

Required Measurements(refer to the measuring diagram):

For Straight Track:

  • Window Width/Coverage width 
  • Side lengths of the triangular top area
  • Circumference of the triangular top area of the coverage area
  • Height of the triangular top area
  • Total top-bottom height

For Curved Track:

  • Window Width/Coverage width 
  • Arch length (measured with a flexible tape)
  • Height from the midpoints of the semi-arch to the floor
  • Vertical arch height 
  • Total top-bottom height

Includes mounting brackets, gliders, pulleys, and S-hooks

Note: This product serves as a custom entry point. Final pricing depends on your window size and fabric selection. Please submit a front-facing photo of your arched window and complete the measurement form. A detailed quote will be provided based on your submission. The listed price is for consultation and is not the final cost.

FAQs

Our Arch Window Resolution Service offers customized solutions for arched windows, including specially measured curtain tracks and optional curtains. Due to the unique shape of arched windows, each order is custom-quoted based on specific dimensions and photos provided by the customer.

To request a quote, simply place an inquiry through this product page. You’ll then be guided to submit a front-facing photo of your arched window along with the required measurements.

Pricing is based on the complexity of the arch shape, material requirements, and total dimensions. Since each project is custom, we’ll provide a tailored quote once we receive your photo and completed measurement form.

Please prepare the following:

  • A front-facing photo of your arched window
  • Accurate measurements according to our form (including width, height, arc length, etc.)
  • Any special requests (e.g., curtain style or fabric preference)

Due to the curved shape, the curtain is usually operated using a pull cord system that guides the curtain along the track.

That depends on the arch shape and curtain type. In many cases, part of the curtain will drape to the floor when open, which is a normal result of the arched form and the way fabric hangs.
