Double Glazed Windows

Are you looking to improve your home’s energy efficiency, reduce noise pollution, and enhance its overall appearance? Then, you might want to consider double glazed windows. In this article, we’ll explore the world of double glazed windows in South Africa, delving into their benefits, cost, and how to choose the right supplier and installer for your needs. Let’s dive in!

What are Double Glazed Windows?

Double glazed windows, also known as double-pane windows, are windows that are constructed with two panes of glass separated by a space filled with air or an insulating gas like argon. The two panes of glass are sealed around the edges to create a single unit.

Double glazed windows provide improved thermal insulation and noise reduction compared to single glazed windows because the air or gas between the panes acts as an insulator. They are commonly used in homes and buildings to improve energy efficiency and reduce outside noise.

Types of Double Glazed Windows

There are various types of double glazed windows available, including casement, sliding, tilt and turn, and fixed windows. These styles can be customized with different glass options, such as low-emissivity (low-E) glass, tinted, or laminated glass, to enhance performance and aesthetic appeal.

1. Casement Windows

These windows have hinges on the side and swing outward. They are popular in modern homes and are available in a variety of styles.

2. Tilt and Turn Windows

These windows open in two ways – they can tilt inward at the top for ventilation or swing inward like a door for easy cleaning.

3. Sliding Windows

These windows slide horizontally on tracks and are ideal for spaces where a casement window would be difficult to operate.

4. Bay Windows

These windows protrude from the wall and create a small alcove or seating area. They are often used in traditional or Victorian-style homes.

5. Bow Windows

Similar to bay windows, these windows also protrude from the wall but have a curved shape.

6. Awning Windows

These windows are hinged at the top and open outward from the bottom, creating an awning-like effect.

7. Double Hung Windows

These windows have two panes that slide up and down within the frame. They are popular in older homes and are often used in traditional or colonial-style architecture.

Benefits of Double Glazed Windows

• Energy Efficiency: One of the main advantages is their ability to improve a home’s energy efficiency. By providing better insulation, these windows reduce heat loss during winter and prevent excessive heat gain in summer. This results in lower energy bills and a more comfortable living environment.
• Noise Reduction: Effectively reduce noise pollution from outside sources. The dual-pane design and gas-filled gap work together to dampen sound vibrations, making your home a quieter and more peaceful place.
• Security: The robust construction offers increased security compared to single-pane windows. The additional pane of glass makes it more difficult for intruders to break in, giving you peace of mind.
• Durability: Have a longer lifespan than traditional windows due to their enhanced construction. High-quality double glazing can last for decades, making it a worthwhile investment for homeowners.
• Aesthetics: With a variety of styles, materials, and finishes available, they can enhance the visual appeal of your home. They can be tailored to match your home’s architectural style and personal preferences.
