As the building of the extension gets along we have been exploring options for windows.
We started by doing lots of research into windows and their properties. We found quite a few websites that have good information on them about windows.
Windows Energy Rating Scheme – WERS rates the energy impact of windows in housing anywhere in Australia. With up to 40% of a home’s energy for cooling or heating being lost or gained through windows, improving their thermal performance reduces energy costs and Australia’s greenhouse gas emissions.
Your Home Technical Manual – Glazing has a major impact on the energy efficiency of the building envelope. Poorly designed windows, skylights and glazed surfaces can make your home too hot or too cold. If designed correctly, they’ll help maintain year-round comfort, reducing or eliminating the need for artificial heating and cooling.
After researching types of windows and the plans drawn up for the extension we took our plans around several local window manufacturers. We knew that we wanted either timber or what is known as composite ( aluminium outside and timber inside) This means that cold or heat can not travel through from inside to outside or vice versa. We had looked at upvc double glazing but decided that they did not look right and used too much energy to manufacture.
The local manufacturers made beautiful timber windows but in red cedar which is imported from Canada and can’r be guaranteed to be plantation grown. We started to look interstate and found two companies that seemed to fit the bill. Miglas and Rylock . Both make composite windows, both use plantation grown Victorian Ash and recycle their aluminium and both built in the look that we wanted which is semi industrial. It was time to get a quote. We sent off emails and got a quote from both. We were very surprised that there was a $12,000 dollar difference.
As I was due to go to Melbourne I managed to visit Rylock and was very impressed with their service and attention to detail. They pointed out several options to help save money and to get the windows and doors to work the way that we wanted.
Since that visit in December 2009 we have revisited the windows and doors and come up with a definitive plan. We have changed our minds from casement windows as they take up alot of room on the deck when opened out to their full 900mm width to sliding windows, cut out a pair of doors and changed them to sliding windows and put a pair of sliding doors into the Northern end. We are now awaiting a new quote.
