What is Double Glazing and How Does it Work?
Double glazing is nothing short of a miracle, helping make New Zealand homes more comfortable and energy-efficient year-round. With double glazed windows, homeowners can cut energy costs, reduce their overall carbon footprint, and keep their homes better insulated and free of moisture and mould. But how does the technology work? Here, we’re discussing everything you need to know about double glazing, and why it’s a home improvement project worth considering if you don’t already have it.
What exactly is double glazing?
Double glazing is a feature you can apply to any windows and glass doors to keep your home from losing heat in winter, or gaining heat in summer. Instead of a single pane of glass, double glazed windows and doors utilise two panes of glass separated by a layer of air or argon gas. This layer is meant to work as an insulator.
How does it work?
When heat is transferred from a hot space to a cold space, it does so through a process is called convection. To make this happen, a good conductor is required. The trapped air in-between the doubled glazed windows has only 67% of thermal conductivity of air, making it a poor conductor of heat. With less heat able to leave the room, your space stays warmer for longer. When argon is used inside double-glazing, heat has an even more difficult time trying to cross through, making it more effective.
What is it made from?
Many double glazed windows are manufactured with UPVC or aluminium frames, which are durable materials commonly used when installing double glazed windows. Your options generally are:
- UPVC frames – Commonly used by homeowners as they’re durable and no longer need regular maintenance.
- Wooden frames – Often used in conservation areas and are better for the environment.
- Aluminium or steel – These are long-lasting options and can be recycled.
Composite frames – These are made from an inner timber frame covered with aluminium or plastic.
What are the benefits of using UPVC double glazing?
UPVC double glazed windows are an ideal option to weather-proof doors and windows as it can cut down heat loss to only 10%. Here are some of the specific benefits of UPVC double glazed doors and windows:
- Reduced energy costs
The addition of glass to your windows and doors helps in improving your home’s energy efficiency. This is because with UPVC double glazed windows, heat has nowhere to escape to, so you’ll find that your home gets warmer quicker, vastly reducing the cost of your energy bill.
- Increased security
Using double glazed windows and doors improve the safety and security of your home as UPVC double glazing is made from more durable materials that are hard to break. At Warm Windows, all windows and doors will have a multi-point locking system, further deterring unwanted intruders.
- Drier homes
New Zealand homes suffer from mould and moisture that can damage your home’s internal components, or cause health issues. With a high-quality UPVC profile that doesn’t conduct heat or cold, water doesn’t build up, giving mould and mildew less chance to thrive.
Double glazing can reduce outside noise by as much as 80% compared to single glazing, and it works best with a UPVC profile serving as an effective sound barrier, turning your home into a comfortable, quieter place.
- Easy to maintain
UPVC joinery requires very little maintenance as UPVC frames don’t rot, wrap, or swell. It’s a worthwhile investment that provides great value for money.
