Double Glazing Christchurch, NZ
Heat loss through single glazed windows can be halved using double glazing!
Stake Glass is your local Double Glazing glass supplier in Christchurch. We partner with Thermoglaz in Christchurch, to provide the best possible Double Glazing systems for wood and aluminium windows.
What Does Double Glazing Do?
Double glazing refers to a window or door system that consists of two glass panes of glass separated by a layer of air or gas.
Also known as an Insulating Glass Unit (IGU) they can be made from two different types of glass depending on the specific requirements of your home. Single glazed windows are the most significant source of heat loss in a home. The more glass surface area you have, the more heat you stand to lose.
However, heat loss through single glazed windows can be halved using double glazing. Double Glazing provides improved insulation by reducing heat transfer and sound transmission between the interior and exterior of a building.
In a double glazed window the gap between the two panes of glass is filled with air. Air is a poor conductor of heat, so heat loss is reduced. This helps enhance energy efficiency, reduce utility costs, and create a more comfortable and quieter living environment.
You can reduce heat loss further by using different glass types, such as Low E Glass (Low Emissivity Glass), or by choosing units which use Argon Gas instead of Air to fill the space between the two panes of glass.
Since 2007, double glazing in NZ has been specified by building standards as a requirement for new homes.
Improvements to the requirements under the H1 Clause of the Building Code, were published by the Ministry of Business, Innovation and Employment (MBIE) in November 2021, and more recently, the transition periods for housing were updated. Click Here for more information.
Benefits of Double Glazing
- A cosy, comfortable home all year round - warmer in winter and comfortably cool in summer
- Healthier home with less condensation - warmer houses have drier windows and a drier home is much healthier
- Double Glazing helps noise reduction - creates a shield against external noises, giving you quieter nights
- Lower energy bills - double glazing offers superior energy efficiency
- Increased security - double glazed windows are much harder to break
- Reduces draughts - well-insulated, warm homes aren’t draughty
- Adds value to your property - indicates to potential buyers that the house is well insulated, warm and cared for
- Reduces fading of furniture and furnishings - minimises the impact of the sun’s harsh ultraviolet rays
Thermal Insulation (Argon Gas)
Boost the insulation benefits of double glazing by combining Argon Gas and Low E glass. This will create high performance double glazing.
What is Argon Gas?
Argon gas is a naturally occurring, non-harmful gas. When argon gas is inserted between the panes of glass it increases the insulating performance of your double glazing. Argon gas is denser than air, so adding it to the air between the two panes improves thermal insulation efficiency.
When a glazing unit features Low E glass and Argon Gas it brings the temperature of the window closer to room temperature. This combination eliminates air currents and drafts that occur when differing temperatures meet.
Low E Double Glazing
You can reduce heat loss further by using Low E Glass or by choosing units which use argon gas instead of air to fill the space between the two panes of glass.
The diagram below outlines how heat passing through your glass reduces when you use Double Glazing, Low E Double Glazing and Glazing Argon Gas instead of Air to fill the space between the two panes of glass.
What is a U-Value?
A lower U-value means lower heat transfer and better insulation of your home.
A U-value measures the rate of heat loss over a surface or material, how much heat passes through your glass.
H1 Building Regulation Changes - Windows & Doors
Improvements to the requirements under the H1 Clause of the Building Code, were published by the Ministry of Business, Innovation and Employment (MBIE) in November 2021, and more recently, the transition periods for housing were updated.
Window and door implementation phasing-in began on the 3 November 2022, with an additional step in the transition period in May 2023. All requirements will be in effect as of 2 November 2023.
Energy efficiency is top of mind, with the update being one of the first steps in the Government’s Building for Climate Change programme. There are major increases in thermal performance requirements across the building envelope and they have introduced new Climate Zones.
For housing, initially, aluminium frames will require more thermally efficient glass (double glazing with a high-quality Low E pane and an argon gas fill between) to meet the minimum requirements.
Stake Glass offers the following two types of high quality Low E glass:
- Planitherm Ultra N Low E Glass
- Cool-Lite Low E Glass
Both Planitherm Ultra N and Cool-Lite Low E glass, meet compliance with the new requirements.
