LOW-E DOUBLE GLAZING
LOW-E DOUBLE GLAZING
STANDARD DOUBLE GLAZING
Low-E Coating / Argon Gas / Thermal Spacer
We generally refer to a double or triple glazing unit as an insulated glazing unit (IGU). The energy efficiency of an IGU can be further improved by the inclusion of Low-E (Low Emissivity) coated glass, which has a special surface treatment which slows the transfer of heat or cold through the glass pane.
For most IGU's, Argon Gas is the preferred choice to fill the space between the glass layers. It is a stable, non-toxic, and relatively abundant (around 1%) in the atmosphere. Around 38% denser than air, Argon Gas slows the transfer of heat & cold from one pane to the other. Argon Gas will not leak from your IGU; manufacturing processes have advanced, and studies have shown that after 10 years, over 90% of the initial Argon Gas is still retained.
Completing the IGU, is a thermal spacer, a surrounding strip of material which is hermetically sealed to keep moisture out. Spacers are typically made of a metal such as aluminium or steel, on our case we use a Thermoset Super Spacer made from polymer foam. This way, we know our Spacer will expand and contract but will always return to it's original shape.
STANDARD DOUBLE GLAZING
Entry Level Double Glazing
Single glazing was the standard for older homes, but it has poor insulating properties; heat and cold pass easily through it. Under the revised clause H1 of the New Zealand Building Code, double glazing is required on all new builds in order to meet national home energy-efficiency targets.
A single pane of glass provides very poor insulation due to glass being a very good conductor of heat. Much of the heat in your home literally goes out the window.
Install Double Glazing, and you have a layer of air trapped between two panes of glass. Because air is a poor conductor of heat, much less heat and energy is lost through your windows and doors.
Double Glazing with a Low-E Coating is relatively inexpensive upgrade to standard double glazing. If the inside of one pane has a Low-E coating, even less heat is lost, because the Low-E coating reflects the heat back into the home.

SPECIALTY DOUBLE GLAZING
Tint / SoundStop Laminate / Colonial Bars
Apart from its visual appeal, tinted float is also used to reduce solar heat gain, UV and glare inside a building.
The solar control quality means the glass is thermally stressed so some thicker or darker products may need to be toughened to avoid thermal stress breakage, especially with Low-E IGU's.
It might be the sound of rain or wind. Or it might be traffic, neighbours and passers-by. If you live in an area with even a moderate level of constant background noise, the difference is noticeable.
If stronger noise reduction is important for your home, we can add special acoustic laminates to your IGU's to help reduce and in some cases all but eliminate the noise. Ask us about SoundStop Laminate Glass and what technical data we can provide.
To retain the heritage look of your home, we offer the following, worked into new Double Glazing:
-
External Colonial Bars
