Double Glazing
Warmer in winter. Cooler in summer. More comfortable all year round. Heat loss through single-glazed windows can be halved using double glazing.
Whether you're building new, replacing existing glazing, or improving the comfort and energy efficiency of your home, Stake Glass can help you find the right double glazing solution. We manufacture and supply high-performance double glazed units and partner with trusted local double glazing specialists, who provide specification, quoting, and installation services to help bring your project to life.
Why double glazing matters?
Windows are one of the largest sources of heat loss in a home. When heat escapes through glass, rooms can feel colder, draughtier, and more expensive to heat. Heat loss through single glazed windows can be halved using double glazing.
Double glazing uses two panes of glass separated by an insulating space filled with air or gas. This extra layer of insulation helps reduce heat transfer, minimise condensation, reduce outside noise, and improve the overall comfort and energy efficiency of your home. Also known as an Insulating Glass Unit (IGU), double glazing is a practical investment that can make your home warmer in winter, cooler in summer, and more comfortable all year round.
Benefits of double glazing
Double glazing offers a range of benefits, helping create a home that is warmer, quieter, more comfortable, and more energy efficient year-round.
A warmer, more comfortable home year-round
Stay warmer in winter and cooler in summer with improved insulation that helps maintain a more consistent indoor temperature.
Reduce condensation and create a healthier home
Double glazing keeps the inside pane of glass warmer, helping reduce condensation, dampness, and the conditions that can lead to mould growth.
Lower energy bills
By reducing heat loss through your windows, double glazing helps improve energy efficiency and can reduce the need for heating and cooling.
Enjoy a quieter home
The insulating gap between the glass panes helps reduce outside noise, creating a calmer and more peaceful living environment.
Reduces draughts
Well-insulated windows help minimise cold spots and unwanted draughts, making your home feel more comfortable.
Adds value to your property
A warmer, drier, more energy-efficient home is an attractive feature for future buyers and can add long-term value.
Double glazing options
Standard Double Glazing
Double glazing consists of two panes of glass separated by an insulating air space. This helps reduce heat loss and improve comfort compared to traditional single glazing.
Low E Double Glazing
Low E (Low Emissivity) glass includes an advanced coating that reflects heat back into the home while still allowing natural light to enter. This improves thermal performance and helps reduce heating demands.
Argon Gas Filled Double Glazing
Replacing air with Argon gas between the glass panes further improves insulation performance. Argon is denser than air, helping reduce heat transfer and improving overall energy efficiency.
High Performance Double Glazing
Combining Low E glass with Argon gas creates a high-performance glazing solution designed to maximise comfort and energy efficiency.
A U-value measures the rate of heat transfer through glass. The lower the U-value, the better the insulation performance. High-performance double glazing helps reduce the U-value of your windows, minimising heat loss and helping create a warmer, more energy-efficient home.
H1 Building Code Requirements
Changes to the H1 clause of the New Zealand Building Code have increased the thermal performance requirements for windows and doors in new homes. The updated standards are designed to improve energy efficiency and support healthier, more comfortable homes.
For many projects, compliance now requires higher performing glazing solutions such as:
- Double glazing
- Low E glass
- Argon gas filled units
- Thermally broken aluminium frames
- uPVC or timber framing systems
Stake Glass supplies high-performance glazing options, including Planitherm Ultra N Low E Glass which can help meet current H1 requirements.
