Because double-glazed reduce heat loss during the winter and coolness loss during the summer, they allow air conditioners and central heating units to run less and keep the building at a constant temperature.
  • Heightened Security: Double glazed windows are actually safer than single-pane windows. The two glass panes of double glazed have internal beading for added security and may be laminated or reinforced to prevent access. All our double glazed come with uPVC frames. uPVC is naturally strong and we weld all the joints of the window frames to make them even stronger. Installing double glazed windows is an important way to deter anyone who wants to force a window open or break it.
  • Noise Reduction: Interested in making your home or office a quieter place? Double-glazed windows are capable of filtering out twice as much noise pollution as a single pane of glass.

Double glazed also add value because they are attractive and protect the interior of the property. Ultraviolet rays enter through any window that receives direct sunlight. These harmful rays damage furniture and discolor carpets, as well as aged paint and wallpaper. The two panes of glass combined with special coatings, standard on double-glazed windows, can filter a large amount of UV rays and keep the interior decoration beautiful for longer.
  • Hassle-free Maintenance:&lt;/strong&amp;amp;gt; Double-glazed windows have multiple components, but are easy to maintain. The two glass panels are well sealed to prevent moisture and dust from entering hard-to-reach places. Plus, the sturdy uPVC frames surrounding the glass naturally resist moisture, never corrode, and never need to be repainted.

Double Glazed Sound Proofing

You will experience a big difference when you install double glazed windows in your home.

You will find that traffic noise is greatly reduced and even if you live near an airport or train station, you will be able to sleep much better and enjoy a healthier living environment.

However, it is important to note that double glazing is not truly soundproof.

When noise reaches single-glazed windows, the glass vibrates. This causes the air on the opposite side of the window to vibrate and this transmits the sound to the ears.

When an additional sheet of double glazing is added, the amount of vibration is greatly reduced and this exponentially reduces noise.

Additionally, when double glazing is installed correctly, there are no gaps or cracks around the window that allow noise to pass through.

The sound hits the sealed frame, preventing vibrations from passing through it, while the argon gas between the two window panes has different properties for handling sound waves compared to normal air.

Since the panels do not come into direct contact with each other, sound waves are dampened, making the interior of your home much quieter.&lt;/p>

In fact, double-glazed windows are capable of reducing sound levels by up to 31 decibels. However, they will not be completely soundproof.

What is double glazed?

<p>Remember those drafty old windows that made winter nights unbearable and summer days sweltering? Double glazed windows are your knight in shining armor!

Double glazing: Quiet (30 dB!), comfy year-round, saves 25% on energy. Enjoy!

Yes, the initial cost may be higher, but the long-term benefits and improved quality of life make it worth the investment. So, upgrade to double-glazed windows and discover a world of comfort, energy efficiency, and peace.&lt;/p&amp;gt;

What are the benefits of double glazed windows?</h3&gt;

data-sourcepos=”1:1-1:167″>Double glazed windows offer a significant number of benefits over single glazed ones, making them a popular choice for homeowners. Here are some of the key advantages:

  • ata-source=””>pos=”3:1-3:287″><strong>Improved Energy Efficiency:&lt;/strong> This is perhaps the most well-known benefit. Double glazed windows act as an insulator, with the gap between the two panes filled with air or gas providing a barrier to heat transfer. This means less heat escapes in winter, keeping your home warmer and reducing reliance on heating systems. Similarly, in summer, the heat from outside is kept out, creating a cooler indoor environment and potentially reducing the need for air conditioning. This leads to lower energy bills and a smaller carbon footprint.</li>
  • -sourcepos=”5:1-5:344″&gt;<strong&gt;Reduced Noise Pollution:</strong> Double glazed windows significantly dampen outside noise, creating a quieter and more peaceful home environment. This is especially beneficial if you live in a noisy area near traffic, construction, or other sources of sound. The reduction in noise can positively impact sleep quality, relaxation, and overall well-being.&lt;/strong>
  • <li data-=””&gt;sourcepos=”7:1-7:193″>&lt;strong>Increased Security:&lt;/strong> Double glazed windows are generally more robust than single glazed ones, with thicker glass panes and sturdier frames. This makes them more difficult to break, deterring potential burglars and enhancing home security. Some double glazed windows even come with additional security features like laminated glass or multi-point locking mechanisms.</li>
  • Reduced Condensation: Single glazed windows often suffer from condensation, which can lead to water damage, mold growth, and a damp feeling in the house. Double glazed windows significantly reduce condensation by creating a warmer inner pane, preventing moisture from collecting on the glass. This improves indoor air quality and reduces the risk of mold growth.
  • pos=”11:1-11:382″><st</li&gt;

rong>Increased Property Value: Studies have shown that properties with double glazed windows can be more valuable than those with single glazed windows. This is due to the combined benefits of improved energy efficiency, noise reduction, increased security, and a more modern appearance. If you’re considering selling your house in the future, double glazed windows can be a worthwhile investment.

What is a double glazed window?

Put simply, double glazing is used in all kinds of glass installations (particularly windows) and involves two panes of glass set in the same frame, that are separated by a thin layer of air (a vacuum) or sometimes inert gas such as argon. It’s this layer between the two panels that’s the magic ingredient.

Are double glazed windows worth it?

Double-glazed windows are very energy efficient, as they can reduce heat loss or heat gain by almost 30% in comparison to single-glazed aluminum windows.

What are the disadvantages of double glazed windows?

1. Double glazed windows and doors can trap heat
2. Double Glazed windows cannot be repaired.
3. They might not be a good match for homes with older architectural styles.
4. Double glazing can cost more initially.
