Round aluminium windows are a stylish architectural choice that can give your space a unique, modern, or even vintage charm. Unlike standard square or rectangular windows, round windows immediately stand out—adding character to both residential and commercial properties. Whether used as a feature in living rooms, attics, bathrooms, or hallways, these windows serve as more than just openings for light—they are design elements on their own.
Aluminium, as a window frame material, is known for its strength, durability, and resistance to corrosion. When paired with the elegant shape of a round window, aluminium frames offer an ideal combination of aesthetics and performance. However, because round aluminium windows are not as common as standard shapes, buying them requires a bit more planning.
In this article, we’ll walk you through 10 key things to consider when buying round aluminium windows—so you can make the best choice for your space, style, and budget.
1. Understand the Purpose and Placement
Before buying round aluminium windows, determine the purpose they will serve. Are they for natural lighting, ventilation, or purely decorative? Their size and placement will vary based on this.
Knowing the purpose helps you choose the right size, opening style, and glass type.
2. Measure Accurately and Choose the Right Size
Round windows are precision-based, and incorrect measurements can lead to installation issues. Measure the wall space carefully or hire a professional to assess the available area.
Sizes typically range from small 12-inch decorative styles to large 48-inch or more feature windows. The size you choose should suit the proportions of the room and the architectural balance of the building façade.
If you’re replacing an old window, make sure your new one matches the existing opening unless you’re doing structural work.
3. Check the Frame Thickness and Build Quality
The beauty of aluminium lies in its strength with minimal bulk. A slim yet strong frame gives you more glass and better views. However, check the gauge or thickness of the aluminium—thicker profiles provide better insulation and strength, especially for large or operable round windows.
Also ensure the frames are corrosion-resistant (preferably powder-coated) and well-finished. Poor-quality frames can warp, fade, or let moisture in over time.
4. Choose the Right Glass Type
The glass you select plays a huge role in energy efficiency, sound insulation, and safety. Consider:
- Tempered or laminated glass for enhanced security and durability.
- Double-glazed units to improve insulation and reduce heat loss.
- Tinted or frosted glass for privacy—especially in bathrooms or stairwells.
- Low-E glass for blocking UV rays and controlling indoor temperatures.
Discuss your needs with your supplier to find a suitable glazing option that works with the round design.
5. Decide on Fixed vs. Operable Design
Round premium aluminium windows are available in both fixed (non-opening) and operable (opening) versions:
Fixed windows are better for decorative or lighting purposes and are more energy-efficient.
Operable round windows (e.g., with tilt-and-turn or awning-style openings) allow for ventilation and are suitable for spaces like attics or bathrooms.
Choose the type based on functionality. If airflow is important, opt for an operable design—but make sure it doesn’t interfere with the aesthetics or structural balance.
6. Evaluate Thermal and Sound Insulation
Aluminium frames, if not thermally broken, can conduct heat and cold. For better comfort and energy savings, choose thermally broken frames that have an insulating barrier between the inside and outside aluminium.
Sound insulation is also important—especially if your round window faces a busy street. Double-glazing and rubber gaskets within the frame can significantly reduce external noise.
7. Match the Style to Your Home’s Architecture
Round windows are versatile, but the style you pick should complement your home’s design. For instance:
- A classic white or bronze round window suits colonial or vintage styles.
- A matte black or metallic finish fits contemporary or industrial homes.
- Decorative grille patterns or crossbars inside the glass give a traditional feel.
Think about how the window will look from the inside and outside—especially if it’s going to be a visual highlight.
8. Check for Easy Maintenance Features
Low maintenance is one of the top reasons to choose aluminium, but not all designs are equal. Make sure the surface is powder-coated to prevent chipping, rust, or fading.
Also consider:
- Whether the glass is easy to clean (especially in operable models).
- If hardware like handles, hinges, or locks is rust-resistant.
- Whether seals and gaskets are replaceable.
Ask your supplier if spare parts or service options are available in your area for future upkeep.
9. Compare Prices and Customization Options
Round aluminium windows are more specialized than standard ones, and costs can vary depending on:
- Size and thickness
- Type of glass
- Frame color and finish
- Hardware and opening style
Get multiple quotes from trusted manufacturers and ask about customization options. You may be able to choose the exact shade, texture, hardware finish, and even the angle of opening if it’s operable.
Be sure to factor in installation charges, especially if your wall needs modification to fit a new round design.
10. Buy from a Trusted Supplier or Manufacturer
Not all aluminium windows are created equal. Choose a supplier with a solid reputation, industry certifications, and clear warranty terms. A good supplier will:
- Offer professional guidance
- Provide accurate installation
- Deliver on time
- Back their products with warranties on the frame and glass
Check customer reviews or ask for references. Reputable companies often have project galleries or customer testimonials you can view online.
Buying round aluminium windows is a fantastic way to elevate the design and appeal of any space. But because these windows are less common than traditional shapes, they require thoughtful planning—from size and materials to glass type and functionality.
With the right considerations, round aluminium windows and aluminium front doors can offer both aesthetic charm and practical benefits like energy efficiency, durability, and low maintenance. Whether you’re renovating an old space or building a new one, this guide should help you navigate your options with clarity.
Take your time, compare options, and don’t hesitate to ask your supplier for a custom solution. With smart choices, your round aluminium windows will become a stunning feature that stands the test of time.
