Benefits of Triple Glazing
Triple glazing refers to a glazing system that uses three panes of glass. This could apply to a slim framed window, casement or pivot door, or rooflight.
In between the panes, there is often a gas-filled cavity, Sieger use argon as it is one of the most insulating options for glazing units. Some glaziers will leave it as an air-filled gap, which has proven to be inefficient when it comes to insulation and thermal performance levels.
There are many differences between triple glazing, double glazing and single glazing, including cost, thermal performance and noise reduction. This article will look at the differences and the benefits of using triple glazed systems in your project.
Thermal Performance
Due to the extra pane of glass and insulating cavity, triple glazed systems are higher in price than double or single glazed systems. Although triple glazing may not be as cost-effective initially, triple glazing can help to save money in the long run.
The increased thermal performance means less money needs to be used heating and cooling the home, which over the years adds up to be a significant amount.
If the effort of reducing our carbon footprints and ensuring each home is as thermally efficient as possible, many would argue that triple glazing should be a requirement for new build homes going forwards.
When building home to Passivhaus standards, triple glazing is often a necessity due to triple glazed windows and doors having unparalleled thermal performance and airtightness compared to double glazed units.
Whether you opt for double or triple glazing for a building envelope, it is vital to ensure that any metal framed glazing has a thermal break. All of Sieger’s external glazing systems use a polyamide thermal break to prevent heat loss through conduction.
Increased Security and Size
If someone was attempting to enter the home through a window or glass doors, having the extra pane of glass makes it extra difficult to get through. The extra pane greatly reduces the chance of someone being able to break through the glass and the deeper frames make it more difficult to remove the glass panes, increasing the overall security of the system.
Triple glazed systems can also generally reach bigger sizes than double glazed systems. Triple glazed windows and doors need a deeper frame profile to allow for the extra pane of glass and insulating cavity, and these deeper frames are able to reach larger sizes.
For example, our Sieger Slim Sliding Door which is a double glazed sliding door with a low e coating as standard can reach 2.5m wide x 3m tall per pane, whilst our Sieger XL Sliding Door which is a triple glazed sliding door can reach 4m wide x 4m tall per pane.
Although triple glazing should be used where possible, it is not always within people budgets and factors such as the type and age of the property should be taken into accounts.
Some older builds are unable to accommodate the deeper frame profile needed for triple glazing, and it is sometimes the case that the building structure cannot support the weight if it is a large triple glazed system.
For these types of projects, it is possible to incorporate triple glazed systems by utilising external structures and supports but this is something that should be discussed with your builder or architect.
