Double Glazing Versus Triple Glazing – Is It Worth It To Get That Extra Layer?
What is the difference between Double Glazing and Triple Glazing
We often get asked the question from clients whether they should go for double glazing or triple glazing. Firstly we must understand the differences between double glazing and triple glazing.
Our Double Glazing windows are more common and a standard stock type of energy-efficient windows. They consist of a Hermetically sealed IGU unit composed of 2 glasses separated by a spacer. The dead space between the 2 panes of glass in double glazing windows, is the main reason for the increase in efficiency by reducing heat and cold transmission through the dead space between the 2 panes of glass.
When we add a third layer of glass, it becomes triple glazed windows. Therefore the composition of triple glazed windows is glass-space-glass-space-glass. They contain 3 panes of glass separated by 2 spacers and therefore are much more efficient than double glazing windows. In practice, the overall IGU thickness in a triple glazed window is more than a double glazed unit. They are generally upward of 35mm whereas a double glazed unit is 28mm or smaller. Triple glazed windows Perth is not very common mainly due to the fact that double glazing itself has not become a standard. When the market firstly accepts the energy benefits of insulated double glazing, triple glazing would be the next step up.
Triple Glazing Windows cost is higher than its double glazing counterpart, however, it does have added energy efficiency benefits. U values of our double glazed windows are a maximum 2.3, and a base triple glazed window has a U value of 1.7. Double Glazing window cost is about $60 per sqm cheaper than the triple glazing window cost. To achieve the same U value as a triple glazing, you can add a Soft Coat Low E glass in a double glazing formation and achieve the same U value of 1.7, Double Glazing windows cost Perth with such a Low e DGU composition would cost less than a triple glazed window whilst achieving the same U Value. Because there are not many local manufacturers of Triple glazed DGU’s, the triple glazing window cost Perth is quite high.
In Conclusion For a market which is making high volumes of Passivhaus standard houses, Triple glazing would be a bare essential to achieve U values as low as 1.0 with Low e triple glazing, however, Double glazing windows Perth cost is something that should be accepted as a standard window prior to being talking about triple glazing. In Europe and America, triple glazing is now a standard, after double glazing ruled its reigns for 30 years. In Perth and Australia the reigns are ruled by single glazed windows, therefore firstly double glazing Perth needs to become a standard before we start to talk heavily about triple glazing. We as a company manufacture both double glazed and triple glazed windows, however as an example to the end consumer they first need to take a shift from a being in a bicycle to go onto a motorcycle and thereafter thinking of buying a car. However for those who have an immediate capability to buy a car and want the best, then yes Low e triple glazed windows are the best, however for the general mass a jump from a bicycle to a motorbike ( single glazing to double glazed), will help them see the immediate benefits of Insulated glazed units and what impact it has on energy efficiency, noise reduction and eliminating risk of cold patches
