Double-Glazed Windows and Doors vs Single Glazing in Perth

Wed, 25 Feb 2026 00:48:55 GMT

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.

The Ultimate Guide to Choosing Double-Glazed Windows

Wed, 05 Nov 2025 17:08:18 GMT

Choosing the right windows for your home isn’t just about appearance—it’s about improving comfort, efficiency, and value. Nu-Look Windows helps homeowners and builders find the perfect double-glazed windows in Perth for every property style, from modern city homes to coastal retreats. Whether you’re renovating or building new, investing in energy-efficient glazing delivers lasting benefits. The same applies to double-glazed doors in Perth, which complement window systems and enhance overall performance. Let's explore this ultimate guide to choose double-glazed options!

Why Double-Glazed Windows Are Worth It

Energy use can rise quickly during hot summers and cool winters. Double-glazed windows create an effective barrier that keeps indoor temperatures stable and reduces reliance on heating or cooling.

Key Advantages Include

Improved Energy Efficiency: The insulating layer between glass panes traps air, reducing heat transfer.
Noise Reduction: Perfect for busy streets or high-traffic areas, double glazing significantly lowers sound levels.
Enhanced Comfort: Keeps indoor spaces cooler in summer and warmer in winter.
Lower Energy Bills: Reduced air-conditioning and heating needs save money over time.
Increased Property Value: Energy-efficient homes are more attractive to buyers and renters.

By choosing high-quality double-glazed windows in Perth, homeowners can achieve a quieter, more comfortable environment while cutting ongoing energy expenses.

Understanding How Double-Glazing Works

Double-glazed systems use two panes of glass separated by a sealed air or gas layer. This design limits heat transfer and helps regulate internal temperatures. The sealed unit is also less prone to condensation, keeping your windows clearer and cleaner.

For added efficiency:

Low-E coatings reflect heat while allowing natural light.
Argon gas fill can help improve insulation compared to standard air.
Warm-edge spacers minimise heat loss around window edges.

These technologies make modern double-glazed windows far superior to traditional single-pane designs.

Energy Ratings and U-values Explained

When evaluating double-glazed windows in Perth, it’s important to understand energy performance ratings. The U-value measures how much heat passes through the window—the lower the U-value, the better the insulation.

U-Value: Indicates thermal efficiency. Aim for a rating below 3.0 for best results.
Solar Heat Gain Coefficient (SHGC): Determines how much solar radiation enters your home.
Visible Light Transmission (VLT): A number between 0 and 1. Think of it like a percentage, the higher the number, the more available light gets through.

High-performance double-glazed windows with low U-values and balanced SHGC ratings offer excellent comfort throughout the year. They keep interiors cooler in Perth’s summer and retain warmth in winter.

Importance of Professional Installation

Even the best double-glazed windows can underperform if installed incorrectly. Professional installation ensures airtight sealing, precise fitting, and long-term durability.

Why You Have to Hire Certified Installers Like Nu-Look Windows

Accurate Measurements: Every unit is made to fit perfectly.
Proper Sealing: Prevents air leaks and water ingress.
Structural Integrity: Ensures frames remain square and stable over time.
Manufacturer Warranty: Professional installation maintains product warranties.

Expert installers handle the entire process, from removing old fittings to sealing new units, giving you peace of mind and lasting results.

Comparing Window Styles

Different window configurations offer varied benefits depending on ventilation needs and room layout.

Sliding Windows: Space-saving and ideal for modern homes.
Awning Windows: Great for controlled airflow even during rain.
Casement Windows: Provide excellent ventilation and unobstructed views.

Each style can be customised with energy-efficient glass and durable frames. Explore design possibilities through our double-glazed windows page for inspiration.

Maintenance Tips for Long-Term Performance

Although double-glazed windows require little upkeep, periodic checks maintain performance.

Clean glass with mild detergent and soft cloths.
Inspect seals annually for wear or damage.
Lubricate locks and hinges to ensure smooth operation.
Keep drainage channels clear to allow water to drain out of the sill framing.

Routine maintenance extends the lifespan of your investment and keeps energy savings consistent.

Benefits of Pairing Windows With Double-Glazed Doors

Combining efficient windows with matching double-glazed doors enhances insulation across the entire home. Doors play a crucial role in maintaining thermal balance and reducing external noise.

Benefits Include

Seamless design continuity between windows and doors.
Improved energy efficiency in open-plan layouts.
Enhanced security through multi-point locking systems.
Greater comfort with reduced temperature fluctuations.

When choosing both, ensure the same glazing specifications and frame finishes for consistent performance.

Double Glazed Doors Perth: The Smart Choice

Thu, 24 Apr 2025 04:01:40 GMT

Living in Perth , we’re no strangers to hot summers and chilly winters. Whether you're building a new home or upgrading your existing space, finding ways to stay comfortable without sending your energy bills through the roof is a top priority. That’s where double glazed doors come in.

These modern solutions are not only stylish but also practical—offering impressive insulation, noise reduction, and even security benefits. If you're considering upgrading your home, here's why double glazed doors are fast becoming a must-have in homes across Perth.

Energy Efficiency That Makes a Difference

Double glazed doors are designed with two layers of glass separated by a sealed air or gas-filled space. This setup acts as a powerful insulator, helping regulate the temperature inside your home year-round. In Perth’s warm climate, this means keeping the heat out during summer while retaining warmth during cooler months.

The result? Less reliance on air conditioning and heating systems, and that translates to lower energy bills. In fact, homes with double glazing can experience a noticeable drop in electricity costs—making it a win for both your wallet and the environment.

Quieter, More Comfortable Living

Perth’s urban and suburban areas can get noisy, whether it’s traffic, neighbours, or even birds in the early morning. One of the lesser-known but much-loved benefits of double glazed doors is their ability to reduce external noise.

The same insulation properties that help manage temperature also work wonders for soundproofing. If you’re after a quieter, more peaceful home environment, installing double glazed doors is a step in the right direction.

Boosting Home Value and Curb Appeal

Let’s not forget style and value. Double glazed doors come in a range of designs, materials, and finishes to suit any home aesthetic—from sleek and modern aluminium frames to timeless sliding glass panels.

Because they offer both aesthetic and functional benefits, double glazed doors can add real value to your property. If you’re thinking about selling down the track, prospective buyers will love the energy efficiency, reduced noise, and updated look.

Improved Security and Durability

Modern double glazed doors aren’t just about comfort and style—they also offer greater security. The dual layers of toughened glass, combined with durable frames and locking systems, make them more resistant to forced entry.

This makes double glazed doors an excellent choice for family homes, especially if you want peace of mind while you’re away. Plus, with materials designed to withstand Perth’s coastal weather conditions, you can trust in their long-term durability.

Make the Switch to Double Glazed Doors in Perth

Whether you’re renovating or building new, double glazed doors are a smart investment for any Perth homeowner. From slashing energy bills to reducing noise, enhancing security, and adding modern style, they tick every box.

A spacious, modern renovation

The owners of this fantastic pad wanted a modern home right on the doorstep of South Fremantle's café strip.
They dreamed of a light-filled living space connected to the outdoors with large expanses of glass.

Rather than demolish their 50 year old home, they gave it a total makeover - changing the look of the home with windows as one of the main features of the renovation.

The clever use of remotely-operable awning highlight windows allows the sea breeze to cool the house with a minimum of effort. While in the colder months the windows are easily closed and the room enjoys additional light and warmth from the winter sun.
