A question we are often asked when consulting with our clients is, “Is Triple Glazed worth it?”. In short, Yes!
Triple glazed is 2 panes of glass as opposed to 1 or 2. The science behind this is that by having the extra pane, you should increase efficiency, a warmer home thanks to less heat loss and also reduce outside noise. Triple glazed windows have a’ U-Value’ of 0.8. The U-value is the term used to measure the energy efficiency of a window, with old double glazing measuring a U-Value of 3, and more modern Double Glazing having a score of 1.6. So, as you can see, triple glazing is a vast improvement.
When weighing up the options when it comes to updating your windows, it is important to understand the main differences between double glazed windows and triple glazed windows. When we fully understand this, we know the full pros and cons of both.
The only real physical difference in both is that triple glazed windows have an extra pane of glass. So can one pane of glass really make that much of a difference?
Double glazing is less expensive and lighter so easier to install as opposed to Triple glazing that may require structural support around the window frame to with-stand the weight.
One of the most important areas to consider that we have mentioned in our site is the U-Value (measurement the energy efficiency). The lower the U-value the better, and signifies that the material works better as a insulator and helps keep your home nice and warm. The U-value of Double Glazing is 2.8 where the U-value of Triple Glazing is 0.8.
Triple Glazed windows have a very low U-Value (the importance of which we mention here) due to the use of a low emissivity coating and Argon gas. On a still night, the temperature of the outer glass surface can easily fall below the exterior air temperature or even its dew point temperature. Condensation occurs when the glass temperature falls below the dew point temperature but rest assured this is perfectly normal and a sign that your window is doing its job. This condensation will not evaporate until the glass is heated by wind, sunlight or heat transfer from inside your house.
Our triple glazed windows will suffer external condensation, as they are very thermally efficient.
If you see that condensation is appearing between the panes of your window this unfortunately means that the seal around the glass is not working as it should. There are options to fix this but it cannot remove any stain or water marks that have appeared up to this point.
The best solution here is to replace the glass unit, a very simple task on modern glazing that has a beaded system. C&S Windows offer a free measuring and quoting service. All old glass units are sorted and skipped for recycling, so please contact us today for further information
If you are seeing condensation appearing on the inside of your window it is because there is excessive moisture in the room. Commonly visible during winter, it occurs when warm air inside the house condenses on cold windows. This is a sign that there is poor insulation quality and can be damaging to your home and to your family’s health. If this is your case, you’ll need to check for air leaks around the window and window sill. We would recommend you give us a call if this is happening as we can recommend if it needs to be resealed or replaced, depending of course on the severity of the gap.
When you research windows and doors for your home, you will often come across technical terms relating to energy efficiency. In short, energy efficiency ratings are broken into letters from A to G. A is the most efficient with G the least, so an A rated window would mean it is a window that only lets out as much heat as it takes in from the outside.
It may be tempting to opt for a cheaper, lower grade window, but what this would really mean is that it could potentially lead to much higher costs going forward, not only in heating bills but further down the line when it becomes time to replace the window. New builds are increasingly subject to minimum energy ratings, so future-proofing your home helps keep it up to date.
At C&S Windows, all the materials we use are designed to be as hassle-free and low maintenance as possible. We would encourage you to contact our team today and we’ll ensure you’re perfectly informed about how to look after your windows.
There are many benefits to fitting you home out with A-Rated Glass. As mentioned here for example, installing energy-rated windows in your home can considerably reduce heat loss, meaning significant savings on your household bills. As well as saving energy you will also be reducing CO2 emissions and helping the environment.
Modern energy-rated windows not only reflect heat back into your home but will also retain heat from solar gain. Our windows and doors provide outstanding weather protection even in the most extreme conditions. Our products are manufactured in Ireland, minimising transportation and fuel consumption from wider exportation.
Our team of experts are at hand today to ensure you’re perfectly informed about everything you need for the perfect window solution.
