Triple Glazing FAQ’s

While triple glazing has many benefits, including improved energy efficiency and noise reduction, there are a few potential disadvantages to consider:

  1. Cost: Triple-glazed windows generally cost more than double-glazed alternatives due to the additional pane of glass and the more complex manufacturing process.
  2. Weight: The extra pane of glass makes triple-glazed windows heavier. This may require stronger window frames and could make installation more challenging.
  3. Less Solar Heat Gain: Triple glazing is very effective at retaining heat within a building, but this also means it’s slightly less effective at allowing solar heat gain than double glazing. This could be a disadvantage in colder months when you might want the sun’s heat to help warm your home.
  4. Replacement Cost: If a unit fails (i.e., it becomes misted), the cost to replace a triple-glazed unit will be more than a double-glazed unit.
  5. Potential Over-Insulation: In some climates, triple glazing might provide too much insulation, leading to overheating in the warmer months. However, this is generally a bigger concern for buildings with large glazing.

Remember, the advantages and disadvantages can vary depending on your specific needs, the quality of the window unit, and the climate where you live. It’s always best to discuss these factors with a window professional.

The cost of triple glazing can vary widely based on many factors, including the size and style of the windows, the frame material, any additional features like decorative glass or specific opening mechanisms, and the installation costs.

On average, you might expect triple glazing to cost approximately 10-15% more than double glazing. However, this is a rough estimate and the actual cost could be lower or higher.

Choosing between triple and double glazing depends largely on your specific needs, budget, and the climate in your area. Both types have their pros and cons, and understanding these can help you make the best choice for your property.

Double Glazing: Double glazed windows consist of two panes of glass with a gap in between, which is usually filled with an insulating gas like argon. They offer significant improvements in insulation and energy efficiency compared to single-glazed windows, which can help reduce your heating bills. They also provide good sound insulation and are generally less expensive than triple glazed windows.

Triple Glazing: Triple glazed windows have three panes of glass, offering even better insulation than double glazing. This can be beneficial in colder climates or in homes where heat loss is a particular concern. Triple glazing also typically offers better sound insulation, which can be a real advantage if you live in a noisy area. However, triple glazed windows are heavier and more expensive than their double-glazed counterparts.

In summary, if you live in a particularly cold climate, have issues with noise, or are focussed on achieving the highest energy efficiency possible, triple glazing might be worth the extra investment. However, for many homes, especially in milder climates, double glazing can offer a good balance of performance and cost.

It’s always a good idea to talk to a window professional who can consider your specific circumstances and help you make the best choice for your needs. At Help 2 Buy Windows, we’re here to provide expert advice and guide you through your options.

Triple glazing uses three panes of glass to create two separate air or gas-filled spaces within the window unit, rather than the single space found in double-glazed windows. These spaces act as insulation layers, preventing the movement of heat and improving the window’s thermal efficiency.

Here’s a step-by-step explanation:

  1. Three Panes of Glass: Each pane of glass is a barrier to heat loss, with the surfaces between the panes coated with a reflective, low-emissivity metal layer that reflects heat into the room.
  2. Insulating Spaces: The two spaces between the glass panes are filled with an inert gas, usually argon, krypton or xenon. These gases are denser than air, providing better insulation and reducing the heat that can pass through the window.
  3. Sealed Unit: The whole unit is sealed to ensure the insulating gas can’t escape and outside air can’t get in. This keeps the window airtight and prevents condensation from forming inside the unit.
  4. Spacers: The glass panes are separated by spacers, often filled with a moisture-absorbing material called a desiccant to help prevent condensation within the window.
  5. Frames: The triple-glazed unit is fitted into a window frame, usually made of uPVC, wood, or metal. The frame is designed to be strong enough to support the weight of the triple-glazed unit, which is heavier than a double-glazed unit.

So, through multiple glass panes, insulating gas-filled spaces, low-emissivity coatings, and airtight seals, triple glazing significantly reduces heat loss, improves energy efficiency and offers superior noise reduction compared to double glazing.

The exact amount of heat saved by using triple glazing depends on various factors, such as the quality of the windows, the size and orientation of the windows, the climate, and the insulation of the rest of the property.

However, to give you an idea, triple glazing can be up to 40% more efficient than standard double glazing, according to some estimates. This is due to the additional pane of glass and the extra cavity filled with insulating gas, which creates a further barrier to heat loss.

The energy savings can be measured using a U-value, which measures how quickly heat can transfer through a material. The lower the U-value, the better the material is at insulating. A typical new double glazed window might have a U-value of around 1.6 W/m²K, while a new triple glazed window might have a U-value of around 0.8 W/m²K, indicating that it’s twice as effective at preventing heat loss.

Remember, while triple glazing can help reduce your energy consumption and heating costs, it’s also important to consider other factors, such as wall and roof insulation and draught-proofing measures, for a comprehensive energy-saving strategy.
