Are you thinking about Double Glazing? These are the most common questions that we get asked at Everglaze …..
What is double glazing?
Double glazing refers to a sealed glass unit comprising 2 sheets of glass separated by a spacer bar around the perimeter. The spacer bar creates a 16 mm air gap between the glass panes. It is this still air gap that creates the insulation break between the inside and outside of the window. The spacer bar has a small hollow chamber inside it that is filled with a moisture absorbing dessicant, preventing condensation or fogging from occurring on the inside of the glass unit.
Can I double glaze my existing windows?
No – not really. You can’t fit a 24mm thick double glazed panel into a window that currently has 3mm glass. It’s not only the glass that causes your thermal and acoustic problems, it’s the seals (or lack of) and frame type. Timber swells and rots, and aluminium frames conduct heat and cold. Replacement windows are the best solution.
What works best for noise? (Either keeping it out or keeping it in)
Using laminated glass, differing glass thicknesses within the double glazed unit, twin compression seals and multipoint locking are the keys to an effective acoustic rated window. Everglaze has them all.
What about sun on double glazing?
The best solution for managing solar heat gain is to actually shade your North and West facing windows in summer, but allow the sun to stream through in winter for you to enjoy the free heat. Tinted glass will help reduce heat transfer in summer but equally blocks the valuable solar heat gain in winter. Once the sun is off the glass the double glazing effectively insulates your home from heating up in summer and prevents heat loss in winter.
What air gap do you use on your windows?
We use a 16mm airgap with 4mm glass each side as our standard unit for thermal performance. It’s the still air that is trapped between the glass that gives the thermal insulation – much like an insulation batt. It has been proven by over 40 years of experience in Europe that 16 – 20mm is the optimum air gap.
How much more expensive are they than “standard” windows?
Typically our windows are 2 – 3 times the price of a standard mass produced 3mm single glazed aluminium window, however this higher up front cost is offset by not having to purchase expensive heavy curtains to try and minimise heat loss. Then add the savings of being able to use smaller heating and cooling units and enjoy the year on year reduced energy bills, and the capital value improvement on your property when you sell.
Do you do double hung windows?
No, but we can make a “look-a-like” which functions much more effectively. Traditional double hung windows offer poor seals (due to their sliding nature), they are high in maintenance and not very secure.
Why do you recommend Tilt and Turn windows?
Because it offers fabulous ventilation, high security, minimal maintenance and ease of cleaning. The sashes can be made up to 2400mm high x 900mm wide.
Do you do replacement windows?
Yes – we offer a complete service. Everglaze and our experienced resellers/installers offer an obligation free measure, design and quote. Our lead time from order to installation is generally 3 – 4 weeks.
Do you only sell your windows in Melbourne?
No – our windows go everywhere around Australia. We’ve recently completed jobs at Mt Buller, Perth, Canberra, Adelaide, Tasmania, Cowra, Balranald and Whyalla. Generally for new house lots we will deliver windows to site and site glaze. With smaller replacement jobs, we would work in with you and your local builder and supply windows to you factory glazed.
Where do your windows come from?
Our frames are extruded in Europe, our hardware is German, glass is made locally and the windows are all fabricated here in Melbourne. One of the big advantages of being locally made is the quality control, and that if adjustments need to be made, it’s the people who made the window who fix the window.
Are your windows environmentally friendly?
Yes definitely – they use a third of the embodied energy that aluminium uses in the manufacture process, they are recyclable and are the most energy efficient window system available. They don’t need painting, don’t rot, twist, warp or corrode, and have a very long life expectancy.
