How to Choose Double Glazed Doors & Windows
Investing in double glazed doors and windows is one of the best ways to improve your home’s energy efficiency, security, and overall comfort. But with so many options available, how do you choose the right ones for your property? Whether you're upgrading an old home or working on a new build, making the right choice is crucial. If you're considering double glazing in Southampton, it's important to know what to look for to get the best value for your investment. Let's dive into the key factors to consider when selecting double glazed doors and windows.
1. Understand the Benefits of Double Glazing
Before choosing double glazed doors and windows, it’s helpful to understand why they are a great investment.
Why Choose Double Glazing?
✔ Improved energy efficiency, reducing heating and cooling costs.
✔ Better noise reduction for a quieter home.
✔ Enhanced security with toughened glass and strong frames.
✔ Lower condensation levels, reducing the risk of mould and dampness.
✔ Adds value to your home and enhances curb appeal.
Now that you know why double glazing is beneficial, let’s look at how to make the right choice.
2. Choose the Right Frame Material
The material of your window and door frames plays a big role in durability, aesthetics, and energy efficiency. Here are the most common options:
Popular Frame Materials
✔ uPVC – Affordable, low maintenance, and energy-efficient.
✔ Aluminium – Sleek, durable, and weather-resistant.
✔ Timber – Classic look, great insulation, but requires maintenance.
✔ Composite – A mix of materials offering strength and insulation.
Each material has its pros and cons, so choose one that fits your budget, style, and maintenance preferences.
3. Consider the Glass Type
Not all double glazing is the same. The type of glass you choose affects insulation, security, and noise reduction.
Types of Glass
✔ Low-E (Low Emissivity) Glass – Reflects heat back into your home.
✔ Toughened or Laminated Glass – Enhances security and durability.
✔ Self-Cleaning Glass – Reduces maintenance by breaking down dirt.
✔ Tinted or Frosted Glass – Adds privacy while maintaining natural light.
If your priority is insulation, Low-E glass is an excellent choice. For homes in noisy areas, laminated glass helps reduce external sound.
4. Select the Right Spacer Bar
The spacer bar sits between the two panes of glass and plays a key role in insulation.
Spacer Bar Options
✔ Aluminium Spacers – Traditional but not as energy-efficient.
✔ Warm Edge Spacers – Reduce heat loss and condensation.
Opt for warm edge spacers to improve energy efficiency and comfort.
5. Check the Energy Efficiency Ratings
Energy ratings help you determine the performance of double glazed doors and windows. Look for:
✔ BFRC Ratings – A++ to E (higher ratings are better).
✔ U-Value – Measures heat loss (lower values mean better insulation).
✔ Solar Gain (G-Value) – Indicates how much heat the glass retains.
Choosing high-rated windows can lead to long-term savings on energy bills.
6. Consider Security Features
Your doors and windows should not only be stylish but also secure. Here’s what to look for:
✔ Multi-Point Locking Systems – Provides better protection against break-ins.
✔ Toughened or Laminated Glass – Harder to break than standard glass.
✔ Internal Beading – Prevents glass from being removed from the outside.
For maximum security, opt for a combination of toughened glass and high-quality locks.
7. Choose the Right Style for Your Home
Double glazed windows and doors come in various styles to match your home’s aesthetics.
Popular Window Styles
✔ Casement Windows – Hinged at the side, open outward for ventilation.
✔ Sash Windows – Classic sliding design, ideal for period properties.
✔ Tilt & Turn Windows – Open in multiple ways for flexibility and security.
Popular Door Styles
✔ French Doors – Elegant, classic double doors for garden access.
✔ Sliding Patio Doors – Great for saving space and letting in natural light.
✔ Bifold Doors – Stylish, modern, and perfect for open-plan living.
Pick a style that complements your home’s architecture while offering functionality.
8. Check for Noise Reduction Features
If you live in a busy area or near a main road, noise reduction is essential.
How to Improve Noise Reduction
✔ Opt for laminated glass to dampen sound waves.
✔ Choose wider air gaps between glass panes.
✔ Install high-quality seals to block external noise.
Good soundproofing makes a significant difference in your comfort level.
9. Think About Maintenance & Longevity
The last thing you want is windows and doors that require constant upkeep.
✔ uPVC and Aluminium – Low-maintenance and weather-resistant.
✔ Timber – Requires regular painting or sealing but offers natural beauty.
✔ Self-Cleaning Glass – A convenient option for minimal upkeep.
Choose materials and finishes that align with how much maintenance you’re willing to do.
10. Get Professional Installation
Even the best double glazed doors and windows won’t perform well if they aren’t installed properly.
✔ Choose a reputable installer with experience and good reviews.
✔ Check for certifications such as FENSA or CERTASS.
✔ Ensure proper sealing to prevent draughts and heat loss.
Proper installation ensures your double glazing lasts for decades without issues.
Final Thoughts
Choosing the right double glazed doors and windows requires careful consideration of materials, energy ratings, security, and style. Whether you’re looking to improve insulation, reduce noise, or enhance security, making an informed choice ensures long-term benefits.
