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 noise?

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 of condensation?

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 whole frame?

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 units.
  • 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 glass?

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 not fail.
