WHO YOU'LL BE DEALING WITH
Coastal Double Glazing is a new Perth name, but the team behind it isn’t new to double glazing – between us, we’ve fitted it in WA homes for more than 35 years. Every job is premium Kömmerling uPVC and Australian-made Tough Glass, matched to your home and built for Perth’s climate. We put your installation time in writing and stand behind it; our installations manager is on-site for every job, ensuring the highest quality work, built to last.

START WITH WHAT IS BOTHERING YOU
Most people come to us for one of these reasons, and plenty for more than one. Get in touch and we’ll look at your home, walk you through your options and what each one changes, and match the build to your situation.
THE PROBLEM
Blinds shut, aircon flat out, and by mid-afternoon it’s still cooking. Come winter, the warmth vanishes the second the heater’s off. It’s uncomfortable to live in, and every month it quietly pads your power bill.
THE FIX
The house holds a steady temperature and the aircon finally gets a rest. Low-E glass and insulating uPVC frames keep summer heat out and winter warmth in – standard on every window, with a solar-control tint for rooms that cop the afternoon sun.
THE PROBLEM
The party next door at 2:30 am when you’re up at 6 for a shift. The freeway you hear from bed. Curtains and roller shutters don’t block it, and the sleep you lose follows you into work and home the next day.
THE FIX
You sleep through it, work through it, switch off at the end of the day. Acoustic glass – a denser pane in the sealed unit – stops sound before it reaches the room. Busy roads and flight paths get a heavier laminated unit.
THE PROBLEM
When a storm hits, old single-glazed windows feel like they’re barely there. And that flicker of doubt – would the house actually hold up to the weather or to someone at the door – sits at the back of your mind.
THE FIX
Your home holds firm, and you stop second-guessing it. Multi-point locks and toughened safety glass are far harder to force than single glazing and built to take a hit – step up to laminated glass in storm zones, plus security screens where they matter most.
OUR RANGE
Whatever the style, it’s the same German-engineered Kömmerling uPVC frame and Perth-made Tough Glass underneath – we can help with with double glazing whether its a retrofit or new build and from one frame to a full house.
Windows
Every opening style in uPVC, sized to your existing frames – retrofit or new build
Doors
Entry doors, patio doors and big glazed openings, all multi-point locked as standard.
Optional Extras
Finishing touches and add-ons we can build into your quote.

Both – windows and doors, any style, from a single frame to a full house, whether you’re retrofitting an existing home or fitting out a new build.
Yes. The uPVC we use is installed across Europe, the Middle East and Asia in climates as harsh as Perth’s – it won’t warp, fade or need painting. Our glass is made here in WA. Both are covered by the 10-year warranty.
For most Perth homes, yes. Windows are where a home gains the most heat in summer and loses the most in winter, so double glazing is the structural fix for comfort, noise and power bills – and it adds to your home’s value. Your real-world result depends on the glass and frame we spec, confirmed at your measure.
A premium window framing material that won’t warp, fade, rust or need painting. It’s a better insulator than aluminium and lower maintenance than timber – which is why it’s the standard for double glazing across Europe.
