Double glazing or triple glazing? Which is better? It’s one of the most common questions asked in the window world. The truth is, both types of glazing work brilliantly. Which one you choose entirely depends on what’s right for your home. So, let’s go through the main benefits of both window glazing options, including:

  • Energy efficiency
  • Noise reduction
  • Cost
  • Security

First thing’s first…

What is the difference between double glazing and triple glazing?

Both terms relate to windows with multiple panes of glass fixed inside their frames. Two panes for double-glazed. Three for triple-glazed. In between the panes, the space is filled with a vacuum, or more commonly a gas like argon or krypton.

Double and triple glazing offers better insulation, while repelling noise and harmful UV rays. With incredibly high performance standards, they ensure your home stays warm in the Winter and cool in the Summer.

Triple glazing thermal performance

Is triple glazing more energy efficient?

Triple-glazed windows boast U-values as low as 0.8 W/m2k. The lower the U-value, the more thermally efficient the window. This makes them particularly ideal for homes across  Buckinghamshire during the Winter.

However, both our double and triple-glazed sealed units achieve A++ Window Energy Ratings. Manufactured by Planitherm, their special coating reflects heat back into the home and prevents heat from escaping. So, whichever glazing you choose, you’re guaranteed fantastic thermal performance and lower heating bills.

Triple glazing Reduces Noise

Are triple glazed windows more soundproof?

Both double and triple-glazed windows are brilliant for noise reduction. This is down to the space between the two panes. The larger the space, the more difficult it is for sound to bleed through. This is enhanced if one pane is thicker than the other(s). Planitherm’s extra coating also improves noise reduction by 20%.

Of course, triple-glazed windows’ extra pane makes for higher quality soundproofing. This makes them ideal for homes near busy roads and other noisy areas. However, if you live in a quiet cul-de-sac in Wendover, double glazing will most likely be more than satisfactory.

Is triple glazing more expensive than double glazing?

As triple-glazed windows require more glass to manufacture, they are more expensive than double-glazing. However, when you consider the extra money you’ll save on heating bills, they are more than a worthwhile investment!

We, of course, have a range of finance options for whatever home improvement you desire!

Are double glazed windows good for security?

Yes! All Premier’s windows are exceptionally resistant to force, preventing intruders from gaining access to your home.

Of course, triple-glazed windows’ extra glass pane makes them more resistant to shattering. However, both our double and triple-glazed windows are available with Planitherm Comfort and Planitherm Comfort Plus glasses. These both have a special layer that makes the glass harder to break.

Also coming with top-of-the-range multi-locking point systems, you can rest assured that both double and triple-glazed windows will keep your home safe.
