Low-E glass has a microscopically thin, transparent coating that reflects heat. The ‘low emissivity’ coating is applied to one side of the glass in double-glazed windows, and works by bouncing back indoor heat into the room while repelling the sun’s heat.
With competitive price and timely delivery, Northglass sincerely hope to be your supplier and partner.
It’s a smart way to control the climate in your home without relying too much on heating and cooling systems.

This glass type has three layers of glass and two insulating air or gas spaces – if standard glass was a cozy sweater, triple-glazed glass is basically a high-tech insulated jacket.

Due to its coating and ability to reduce the amount of heat transferred through it, Low-E glass is very energy-efficient, decreasing energy usage and costs.
In the same vein, triple-glazed glass is an effective barrier that increases a window or door’s insulating properties. This gives it a higher energy rating (ER) and lower solar heat gain coefficient (SHGC) – so you get improved overall energy performance.
Low-E glass is generally less expensive than triple-glazed glass – but the long-term energy savings for triple-glazed glass can offset the initial cost, making it a worthwhile investment, particularly for homeowners in harsher climates.
Low-E glass, being similar in weight and thickness to regular glass, doesn’t usually require any special adjustments to your existing window frames or hardware.
On the other hand, triple-glazed glass is heavier and bulkier, so the frames and hardware may need to be reinforced. You should make sure that your window frames can support the extra weight. At Panda Windows & Doors, we recommend comprehensive assessment and preparation by specialized installers for our triple-glazed windows.
Maintenance for both types of glass is similar to that of any window. Regular cleaning with a non-abrasive cleaner will keep the glass clear and streak-free. Just remember, the Low-E coating is usually on the inside of one of the panes, so take care not to scratch it during cleaning.
With proper installation and maintenance, both Low-E and triple-glazed windows can last for decades.
When it comes to aesthetics, Low-E and triple-glazed windows offer a clear view of the outside world. However, Low-E coatings can sometimes have a slight tint, depending on the type of coating used. This can improve the look of your windows and even contribute to reducing glare inside your home.
Triple-glazed windows, with their additional pane, look slightly thicker, which might affect the aesthetics of ultra-slim frame designs. But for most homeowners, the added benefits of energy efficiency and noise reduction far outweigh these minor aesthetic inconveniences.

Yes, Low-E glass is versatile and can be used in various climates. It’s particularly effective in areas with extreme temperature differences between seasons. If you’re in a milder climate, Low-E glass can still provide benefits by maintaining a comfortable indoor environment and reducing UV exposure.
Consider triple-glazed glass if you live in an area with harsh winters or hot summers. If energy efficiency and noise reduction are top priorities for you, triple-glazed windows are an excellent choice. Our team can help assess your home’s specific needs to determine if triple-glazed glass is the best option.
Both Low-E and triple-glazed windows are designed to last. With proper installation and maintenance, these windows can perform well for decades.
Absolutely! Besides its superior energy efficiency, triple-glazed glass offers excellent noise reduction. It also provides enhanced security due to its additional pane.
Choosing the right glazing is a big investment when replacing your windows, so if you’re considering triple glazing, we’ve put together the reasons why it may be the right, and most efficient, choice for you.
Triple glazing adds a third pane of glass to standard double glazing. By adding a third pane of glass, you create an extra layer to prevent heat escaping, and cold from entering, your home. The air spaces between the 3 panes of glass have a 90% fill of inert gas called Argon which increases heat retention and acts as a better buffer than dry air alone.
Triple glazed windows were first introduced in Sweden many years ago, as colder climates receive the most benefits from these high-performance windows due to their improvement of interior comfort climate. This makes them ideal for homes in Dublin and Northern Ireland.
The ‘U-value’ measurement is an industry standard for comparing the energy performance of windows. U-values measure how effective a material is an insulator. The lower the U-value is, the better the material is as a heat insulator. This means the lower the U-value of your windows, the better they will be at retaining heat within your home. This will help to keep your family warm and comfortable, whilst helping you spend less on your energy bills.
Below is a comparison of U-values offered by ‘A’ rated double glazing, ‘A’ rated triple glazing, and our ‘A’ rated triple glazing with two coats of Planitherm Total +. As an indication, the average U-value for triple glazed windows, with a Low-E coating, is between 0.9 – 1.0 W/m2k.
Glazing U-Value ‘A’ rated double glazing 1.2 W/m2k ‘A’ rated triple glazing 0.9 W/m2k ‘A’ rated triple glazing with 2 x coats of Planitherm Total + 0.7 W/m2kHere at Turkington, we typically use ‘Planitherm Total +’ thermal glass units. This glass has a metal oxide coating that helps reflect heat back into your home. It maximises solar gain and minimises heat loss. It also lets in natural light without the haze and tint of cheaper options.
Spacer bars are traditionally a continuous aluminium frame that separates the glass panes in a glazed unit. The spacer bar is bonded to the glass panes via a primary and secondary seal, creating the airtight cavity which is filled with argon gas.
Here at Turkington, we use a warm edge spacer bar. This is a plastic composite bar that insulates the edges of our glazed units. Unlike aluminium, plastic does not conduct heat, meaning our warm edge spacer bars retain heat better than standard spacer bars.
The intelligent structure of triple glazing continues to heighten the security of homes across Ireland, as it is exceedingly harder to break than double, single or secondary glazing. Not only does triple glazing offer better security, our Secure by Design locking and 4-part fitting system works to reduce draughts and noise helping to keep your home both safer and more comfortable.
Since our establishment in , Turkington Windows has built a reputation as a leading window installer, supplying to homes across Dublin and Northern Ireland.
