Double-Glazed Windows and Doors vs Single Glazing in Perth

If you live in Perth, you already know how much the weather can swing from hot, dry summers to cold, wet and windy winters. The type of glass in your windows and doors plays a big role in how comfortable your home feels year-round. At Nu-Look Windows, we speak with Perth homeowners every day who are weighing up upgrades and trying to understand what actually makes a difference. This post explains how single glazing compares with double-glazed windows and doors, and why the right choice can improve comfort, efficiency, and liveability.

 

What Are Double-Glazed Windows, and How Are They Different?

Single-glazed windows use one pane of glass in the frame. That is the traditional style found in many older homes. Double glazing uses two panes of glass separated by a sealed gap filled with air or gas. That gap acts as an insulating barrier.

 

This simple structural difference leads to several performance gains. With double-glazed windows you get:

• Better thermal insulation
• Reduced outside noise
• Improved energy efficiency
• Added UV filtering depending on glass type

 

Single glazing still works, but it offers far less protection against heat, cold, and depending on the selection, noise reduction can be minimal. In a climate like Perth, that gap in performance becomes very noticeable.

 

Why Perth’s Climate Makes Glass Choice So Important

Perth homes deal with strong sun, high summer heat, and cold winter mornings. Large window areas are great for light and views, but they can also let in unwanted heat and allow indoor warmth to escape.

 

Double-glazed windows perform better in these conditions because they slow down heat movement. In summer, they help keep hot air and radiant heat outside. In winter, they help keep indoor warmth inside.

 

This means:

• Rooms stay more stable in temperature
• Air conditioners and heaters do not work as hard
• Energy bills can be reduced over time
• Comfort improves across all seasons

 

For homes with large window openings or west-facing glass, the difference is often very clear.

 

Noise Reduction Benefits You Can Actually Hear

Noise is a growing concern across many suburbs, especially near main roads, flight paths, and busy community areas. One of the most appreciated benefits of double-glazed windows is sound reduction.

 

The dual-pane structure and sealed air gap reduce how much sound vibration passes through the glass.

 

Many homeowners notice:

• Less traffic noise
• Reduced neighbour and street sounds
• Quieter indoor living spaces
• Better sleep quality

 

While double glazing is not fully soundproof, it can significantly soften outside noise compared to single glazing.

 

UV Protection and Furniture Fading

Sunlight is great, but constant UV exposure can damage flooring, curtains, artwork, and furniture. Perth’s strong sun can cause fading faster than many people expect.

 

Modern double-glazed windows can be made with specialised coatings that filter a large portion of UV rays. This helps protect:

• Timber floors
• Upholstery
• Rugs and carpets
• Cabinets and finishes

 

Poorly specified single glazing will offer minimal UV control unless special films are added later. Building UV protection into double-glazed windows from the start is usually more effective and longer-lasting.

 

Where Double-Glazed Doors Fit Into the Picture

Windows are only part of the story. Glass doors have just as much impact on comfort and efficiency. Large sliding or stacking doors are popular in Perth homes, especially those opening to alfresco areas.

 

Double-glazed doors provide the same core benefits as double-glazed windows:

• Improved insulation
• Better noise control
• Reduced heat gain
• Stronger overall performance

 

If you upgrade only the windows but keep large single-glazed doors, you may still lose a lot of thermal efficiency. That is why many homeowners choose to upgrade both at the same time.

 

When Should You Upgrade Windows and Doors Together?

Upgrading everything at once is not always required, but there are situations where it makes practical and financial sense.

 

Consider upgrading both double-glazed windows and double-glazed doors together when:

• You are renovating or extending your home
• Existing frames are ageing or damaged
• You want a matched look and finish
• Energy efficiency is a top priority
• You have large glass areas throughout the house

 

Doing the work in one stage can reduce labour duplication and ensure consistent performance across the building envelope, as well as reducing the disruption to you and your family.

Cost vs Long-Term Value

Double glazing costs more upfront than single-glazed units. That is true. But the value should be measured over time, not just at purchase.

Long-term benefits can include:

• Lower heating and cooling costs
• Increased property value
• Better indoor comfort
• Reduced condensation issues
• Less reliance on heavy window coverings

 

For Perth homeowners, a double-glazed windows upgrade is a smart investment that pays off in the long run.
