1. Do you put another piece of
glass in front of the existing glass?
No, Christchurch Glass will always remove your existing glass
and recycle it. New insulating glass units will be made to measure
and installed into your existing frames.
2. What are the advantages of
Low E and argon?
The use of Low Emissivity (Low E) Glass and argon gas increases
the thermal performance of your windows. An increase in thermal
performance will result in a consistent temperature in your home
throughout the year, retaining more heat in winter and reducing
solar heat gain in summer.
3. How long does the
installation process take?
A typical house will require three full days on site. We only
remove the glass we are about to replace so your home will always
be left safe and secure at the end of each day.
4. How long can I expect to
wait from acceptance of a quote until installation date?
Our installation lead times vary with season and demand. Your
Christchurch Glass sales consultant will be able to inform you of
this at the time.
5. Can you make a fixed window
an opening sash and vice versa?
Yes, in most cases we can remove an opening sash and replace
with a fixed panel and vice versa.
We can also remove the transoms and mullions (horizontal and
vertical aluminium bars) to enable full height or width glass to be
fitted leaving you with a less obstructive view. Upon assessment of
your home, your Christchurch Glass sales consultant will be able to
advise you of your options.
6. Will double glazing reduce
Yes it will. By removing your single glass and replacing with
standard double glazed units, you will notice a reduced amount of
perceived noise into your home through the windows. Because there
are now two pieces of glass sealed with an air (or argon) space
between them, sound transmission into your home is reduced. We can
also engineer a higher performance unit to deal specifically with
noise while still offering all the increased comfort levels of
standard double glazing. However noise will also enter through gaps
in the frames and building envelope, and in some cases advice from
an acoustic consultant is wise.
7. Will double glazing reduce
fading effects caused by Ultra Violet light?
Yes it will, but the amount depends on the glass type selected.
If a reduction in fading of furniture and furnishings is a
priority, we can offer a unit that will not only reduce heat loss
in winter and heat gain in summer, it will also reduce the harmful
UV rays and visible light that causes fading.
8. Will double glazing get rid
Double glazing will normally reduce the amount of condensation
forming on the inside of your windows; however an assessment of
your home by a Christchurch Glass sales consultant will better
confirm this, as poorly insulated houses can still have
condensation problems .
Every home has different conditions. But the factors that
influence condensation are outside/inside temperature, inside
relative humidity, insulation (ceiling, wall, window and floor),
and the amount of ventilation and heating.
9. Do you have to replace the
No, the majority of the time we will be able to fit double
glazing into your existing frames.
10. How much does it cost?
It is a very difficult process to offer an approximate price
before assessing the home. When we assess the home, we are looking
for several different variables that will that will achieve the
desired results in your home and, in turn, contribute to the cost
of the Double glazed units.
These variables include:
- The age and condition of your existing joinery
- Compatibility of your existing joinery with new double glazed
- Volume of glass in the home.
- Double glazing make-up required to both comply with current
building code and achieve the desired results.
- Access to your current windows for installation.
Unfortunately there is no such thing as a "one solution fits
all" as every home has different sized windows, amounts of safety
glass required and complexities around access to the glazing area.
All of these factors influence the price.
We also like to view the home we are pricing as most homes will
benefit greatly from double glazing, but some will require
additional insulation before double glazing will have the desired
effect. For this reason we prefer to identify and assess the needs
of the homeowner before suggesting a solution.
11. Can you use any of my old
No. There is no way to be sure that the existing glass in your
home will maintain its integrity and durability. Because we
warranty our units for 10 years, we will custom build a unit to
suit your existing frame. That way, we know the complete life
history of the glass used and can be confident that the units will
