Double Glazing for Existing Windows in Perth
Magnetite Perth commenced trading in 2006, initially from the same premises as our existing family business, Rayban Window Tinting in Malaga. Adapting Magnetite’s retrofit double glazed window system into the existing tint business filled a void for customers who wanted to soundproof their windows and boost thermal performance, without sacrificing natural light.
Perth summers are brutal. Temperatures regularly exceed 35°C, sometimes reaching 45°C+. Your air-conditioning system runs nearly 24/7 from November through March, driving electricity bills to their highest of the year. Single-pane and older double-glazed windows allow heat to pour in, forcing your cooling system to work harder and longer. Traditional replacement windows are expensive and disruptive—retrofit secondary glazing is the proven solution.
Retrofit double glazing adds a new glazed layer inside your existing window frame, creating an insulating air cavity. In summer, Solartite reflective film reduces heat gain by up to 76% (WERS-tested), cutting air-conditioning demand significantly. Installation takes just 1–2 days per room. Your original windows remain completely untouched.
Retrofit secondary glazing costs significantly less than replacement windows—typically 40–60% less, depending on window size and count. Installation is non-invasive and reversible. Many customers recover the investment within 5–10 years through lower cooling bills alone.

Summer Heat Management & Air-Conditioning Cost Reduction
Perth’s summer cooling season runs long—November through March, sometimes into April and October. Single-pane windows and poorly sealed older double-glazing are energy disasters during these months. Heat floods through windows constantly, forcing your air-conditioning system to run longer and harder, consuming more electricity and driving bills skyward.
Retrofit double glazing with Solartite reflective film creates a thermal barrier that reflects heat before it enters your home. In summer, it reduces heat gain through windows by up to 76% (WERS-tested). This means your air-conditioning system doesn’t have to work as hard, runs for fewer hours, and consumes less energy—directly lowering your electricity bill.
WERS (Window Energy Rating Scheme) testing is independent, Australian-standard thermal performance verification. Our retrofit systems achieve WERS ratings equivalent to premium replacement windows, at a fraction of the cost. Real-world customer reports from Perth indicate 25–35% reduction in summer cooling bills—substantial savings during Perth’s long, hot cooling season.
You’ll see the benefit immediately in your electricity bill. Summer months require significantly less air-conditioning. Most Perth customers report payback from energy savings alone occurs within 5–10 years. Peak-hour electricity costs (which spike in summer) see the most dramatic reduction.

Why Retrofit Double Glazing Works in Perth
Perth summers are relentless. From November through March, temperatures regularly exceed 35°C, sometimes climbing to 45°C+. Single-pane windows and older double-glazing allow heat to flood into your home unchecked. Your air-conditioning system runs constantly, consuming enormous amounts of electricity and driving peak-hour bills to unsustainable levels.
Retrofit secondary glazing solves this by adding a reflective barrier (Solartite film) to the inner glazed panel. This film reflects heat before it enters your home, reducing solar heat gain by up to 76% (WERS-tested). Combined with the insulating air gap (100–125 mm), retrofit glazing dramatically reduces the amount of heat entering your home during Perth’s extreme summer months.
WERS testing shows retrofit glazing with Solartite achieves equivalent summer cooling performance to premium replacement windows at a fraction of the cost. Homes in Perth experience noticeably cooler indoor temperatures during summer—bedrooms are cooler at night, living rooms are comfortable without running air-conditioning constantly.
Installation typically takes 1–2 days per room. We work room-by-room, so you’re never without windows. No structural changes, no approval delays for most Perth homes. The system is reversible—you can remove retrofit glazing without damaging your original frames.

What Our Customers Say
“These guys where in and out without fuss leaving the room spotless. The effectiveness of the sound proofing, which was our aim, has been very effective.”
Pawley, WA
“The window fittings are really unobtrusive, you have to look specifically at the window from fairly close to see them, so they haven’t altered the overall look of the windows. They have already made a difference in a recent hot day.”
Anna, WA
“Our house is toasty warm and we are able to turn our air conditioning down by 3 degrees! What a saving!”
Arnola, WA
“Very effective sound-proofing solution. Worked exactly as advertised. The installation was very well done and the installers left the area spotless”
Jonathan, WA
“The noise reduction was immediately evident and, despite the hot weather we have had over the last two weeks, I have not needed to switch on the air conditioning in that part of the house.”
Pica, WA
“I live on an extremely busy main road. After fitting Magnetite windows and door seal to the front of my house, the road noise is barely noticeable. Graeme and his team are very knowledgeable and professional.”

Frequently Asked Questions
Does double glazing really reduce noise in a Perth home near a freeway, rail line or flight path?
Yes. Magnetite’s secondary glazing is designed to reduce common noise such as traffic, trains and noisy neighbours. That makes it well suited to Perth homes near the Mitchell and Kwinana Freeways, busy arterial roads and rail lines. For lower-frequency noise such as aircraft or freight trains, the Perth team may recommend Soundtite, which uses laminated glass.
Can retrofit double glazing help keep my Perth home cooler in summer?
Yes. Perth’s long, hot summers put a lot of pressure on windows, especially west-facing ones. Magnetite creates an insulating air gap that reduces heat transfer through your existing window. Pairing it with Solartite window film further limits heat from direct sun, which helps keep rooms cooler and takes load off your air conditioning.
How much does retrofit double glazing improve window performance?
In acoustic lab testing, Magnetite improved the sound insulation rating of a standard single glazed window by up to 70%. It also improves the thermal performance of your existing windows, helping keep your home cooler in summer and warmer in winter.
Do I need to replace my existing windows to get double glazing?
No. Magnetite is a retrofit system that installs onto your window sill or reveal, so your existing window stays in place and unaltered. For most Perth homes and offices, that makes it a faster, less disruptive and more cost effective option than full window replacement.
How long has Magnetite been operating in Perth?
Magnetite Perth is a family-run business that has been operating since 2006. It started alongside Rayban Window Tinting in Malaga and now works from its office and showroom on Crocker Drive, Malaga.
Which areas of Perth does Magnetite service?
Magnetite Perth installs in homes and businesses across the metro area, from Mindarie in the north to Mandurah in the south.
Can Magnetite help with both noise and heat, or just one?
Both. Whether your main concern is road noise, summer heat or winter chill, Magnetite is designed to address noise and thermal comfort together in one installation.
