Choosing Your Glass - Low-E Options

LOW E GLASS

The glass you choose for your windows and doors will make a big difference to your comfort at home and the size of your energy bill!

Our glass suppliers have a range of glazing options available that can significantly increase the efficiency of your home, ultimately increasing the overall insulation rating of your home.

Low E is a virtually invisible high-tech coating which allows light into your home yet reflects heat.


HOW LOW E WORKS

The protective coating on the glass effectively forms a barrier, reflecting heat back from the glass to reduce heat loss, while at the same time reducing solar gain.

During the winter, the warmth generated indoors is reflected back into your home, resulting in less heat loss. In the summertime, the outside heat is reflected away giving you a cooler more comfortable home.

It can also help in reducing the levels of condensation in your home.

To even further increase the performance of Low E double glazing, a thermal spacer and gas is added to the unit.

Some of the higher performing Low E double glazing options are so good at reducing heat loss, they provide better performance levels than standard triple glazing options.


BENEFITS


GREATER INSULATION, MORE COMFORT

By improving your insulation, you will see reductions in heat loss and solar gain, reductions in heating and cooling bills, and constant temperatures meaning your comfort level is increased.


LESS CONDENSATION

Because Low E glazing increases the internal glass surface temperature, it will reduce the chances of condensation inside your home. Making for a drier, cosier & healthier environment for you and your family.


SMALLER ENERGY BILLS

Low E will ensure your home is less reliant on your heating and cooling systems, resulting in significant energy savings over the course year. Winning!


GLARE REDUCTION

Larges panes of glass can create glare by letting in too much light. This can be reduced by using Low E products or by adding a tinted pane. This can however make your home a little darker during the day. By reducing glare you also help with the fading of your furnishings. Some of the higher grade options can reduce the level of fading, let in plenty of light and keep your home at a constant temperature.


CHOOSE THE LEVEL OF PERFORMANCE YOU NEED

There are several options available based on your personal requirements. We can talk to you about the different choices and what benefits come with each.


OTHER POINTS

Different parts of New Zealand have minimum requirements for insulation. If you’re not sure which area you fall into, we can help you work it out.

On colder days, some areas can see morning dew form on the outside pane. We usually see this in houses that don’t have eaves, are sheltered from the breeze, or with high humidity and cold nights. This will not affect the performance of your double glazed unit.


CHANGES TO THE NZ BUILDING CODE

Upcoming changes to the building code mean you will need to have upgraded glass to meet requirements. Please see our blog on these changes – we will talk to you about your individual requirements and ensure you meet code based on your consent date.
