What Are Double Glazed Windows?

Double glazed windows consist of two panes of glass with a space between them, usually filled with air or inert gas like argon. This design forms a barrier that improves insulation compared to single-pane windows.

How Do They Work?

Imagine wearing a thick winter coat that traps warm air — that’s similar to what double glazing does. The gap between the panes reduces heat loss and helps keep your home warm in winter and cool in summer.

Key Benefits of Double Glazing

• Energy efficiency: Less heat escapes, so you use less energy for heating

• Improved security: Two panes are harder to break than one

• Reduced noise: Helps block out external sounds

• Condensation control: The sealed unit helps prevent moisture build-up

Types of Double Glazed Windows

There’s a style to suit every home, including:

• Casement windows – Hinged at the side, easy to open

• Sash windows – Traditional vertical sliding design

• Tilt & turn windows – Flexible for ventilation and easy cleaning

• Bay windows – Add space and light

Frame Material Options

Double glazed units can be fitted into various frames:

• uPVC – Affordable, low-maintenance

• Aluminium – Sleek and modern

• Timber – Classic look, great for period properties

• Composite – Combines materials for enhanced performance

Double Glazing and Energy Efficiency

Double glazed windows help you lower heating bills by reducing heat loss. Many products carry an energy rating so you can choose the most efficient options for your home.

Security Features

Double glazed windows provide:

• Tougher barriers against intruders

• Multi-point locking systems

• Laminated or toughened glass options for extra safety

Noise Reduction Qualities

If you live near a busy road or in a noisy area, double glazing helps to create a quieter, more peaceful indoor environment.

Maintenance Tips

• Clean frames and glass regularly with mild detergent

• Check seals for any signs of wear

• Lubricate moving parts annually

Cost Considerations

Costs vary based on:

• Window size and style

• Frame material

• Type of glass (standard, low-emissivity, laminated)

While the initial investment can be higher than single glazing, savings on energy bills make it worthwhile in the long run.

Choosing the Right Supplier

Look for:

• FENSA or CERTASS certification

• Good reviews and local reputation

• Clear guarantees and aftercare services

Installation Process

1. Survey and measure

2. Manufacture custom units

3. Remove old windows

4. Install and seal new double glazed units

5. Final checks and clean-up

Double Glazing and Property Value

Homes with modern double glazing tend to attract buyers because of the improved energy efficiency and security features. It’s a worthwhile upgrade if you’re thinking of selling.

Environmental Impact

Double glazing reduces energy consumption, helping lower carbon emissions. Many manufacturers now use sustainable materials and recycling in production.

Conclusion

Double glazed windows are an excellent investment in comfort, security, and energy savings. With a variety of styles and materials to choose from, you can find the perfect solution for your home. If you’re ready to upgrade, make sure to select a trusted supplier to ensure quality and durability.
