Choosing The Right Window For Your Waiheke Home
The Default
When renovating or building on Waiheke, it may be overlooked, but choosing the correct window is one of the most vital decisions you will make. They are more than just aesthetics. They affect the comfort of your home and have a big impact on energy efficiency. Most people will automatically default to aluminium double glazing because they believe that is the best option. However, what if I told you that double-glazed aluminium could be costing you money on energy and even posing health risks for your family?
The Problem
The issue is that when you install a window, you are essentially cutting a hole in the wall and filling it with a transparent barrier. If you do not choose a sufficient barrier with enough thermal defence, you are basically leaving a gaping hole in the wall, allowing energy to escape.
The problem with aluminium windows is that they are excellent heat conductors. This means temperature travels through the frame very easily. In other words, the aluminium frame becomes a channel for cold and hot air to move through, which means it takes more energy to warm and cool a home. This is the perfect situation for condensation to form. When the outside temperature is different from the inside, condensation can occur. This increases the chances of mould growth, which can cause serious health problems for your family if left unnoticed.
Aluminium Windows
This is not to say aluminium should be ruled out altogether. Aluminium can still be a great choice. However, it is important not to rush out and buy a second-hand double-glazed window thinking you are getting a great deal. You want to make sure the aluminium window has a thermal break built into the design.
A thermal break, usually made from polyamide (a type of strong plastic), is sandwiched between the inner and outer parts of the frame. It acts as a barrier that stops the transfer of heat or cold, which is where the name comes from. So if you really like the look and durability of aluminium, make sure you choose one with a thermal break in the frame.
Pros
Modern, clean look that suits a wide range of homes
Very durable and strong, allowing for larger panes of glass
Low maintenance and weather resistant
Slim frames maximise natural light and views
Cons
Without a thermal break, aluminium conducts heat easily, reducing energy efficiency
Can lead to condensation and mould if not well insulated
Not as thermally efficient as timber or uPVC unless specifically designed to be
uPVC Windows
uPVC is a great option for the average householder who values comfort and energy savings. Thanks to its low thermal transmission, uPVC windows prevent condensation, are easy to maintain and also offer excellent noise reduction. However, they do have some downsides, like limited colour choices and styles. They might not suit every type of house and can have some aesthetic limitations.
Pros
Provides excellent thermal and noise reduction properties
Weather resistant and easy to maintain
Cost-effective in the short and long term
Cons
Limited design and colour options
May not suit all home styles
Not as strong, which can limit glass sizes
Timber Windows
The last and most common option is timber-framed windows. This comes as no surprise. Timber windows are traditional in classic New Zealand homes, especially heritage homes, and are often made from native timbers. They bring character to a home while offering exceptional insulation.
Pros
Timber is a poor conductor of heat, which means it has great thermal performance
Aesthetically pleasing and provides a traditional look
Made from a renewable source
Cons
Requires regular maintenance to prevent cracking and moisture damage
Can be susceptible to rot and borer
Generally more expensive
Summary
To summarise, choosing the right window really comes down to what you value most. If you prefer the traditional look and are happy to stay on top of maintenance, timber may be your best option. If you are looking for a budget-friendly and low-maintenance choice, uPVC is well worth considering. If you like a modern look and want something very robust, then aluminium might be the way to go.
Just remember if you’re installing a new window then consult a professional for advice, it is unlikely that windows just pop in and out, changing the window may require altering your structure, which will require a consent, so it’s best to seek advice and check with your local council.
