Double Glazing for the Northern Beaches

Posted by Paul Ackling 31st Oct 2019

Double Glazing

Double glazing is often associated with the cold weather climates of Europe or the snowfields. However, its energy-efficient properties also bring a positive and notable impact on the homes built in our temperate Northern Beaches climate.

Double glazing is quite simply two sheets of glass separated by a pocket of air or an inert gas such as argon. It’s this pocket of air or gas that provides the insulation barrier by reducing the thermal convection between the internal and external surfaces of the home.

Consider hot coffee. You pour one cup into a thermos flask and the other into a glass container. Which one will retain its temperature longer? The same concept applies to double glazing and the inside of your home.

Energy Consumption Savings

To power heating and cooling devices in the home is responsible for half of the energy consumption. By reducing the heat loss or gain, double glazing will reduce the need for electrical temperature control. In practical terms this means that you can come home after work on a summers day to a cool home, then as the temperature drops into the evening, the doors and windows can be opened wide to make the most of that sea breeze.

By shutting up the double glazed windows and doors in winter, the warmth from the sunlight during the day is retained inside your home. Coupled together with the acoustic properties, this provides a warm, snug and quiet internal environment which is maintained with minimal need for heating appliances.

With a reputation of being hugely expensive, many people discount double glazing prior to really considering it. However, the numbers can stack up over the lifetime of your home.

In fact, looking at the additional outlay of approximately $10k to $15k to double glaze an average new home against the. feedback on power bills we have from past clients. I estimate the cost outlaid is recouped after only 10 years or so. This is certainly a short timeframe in the life of the home.
