DOUBLE GLAZED WINDOWS AND DOORS
Penot is a Perth based, WA owned and operated company.
Designed & Built for WA Conditions
At Penot Double Glazing, we don't just install windows and doors, we design solutions for the way Western Australians actually live. Every system uses thermally broken aluminium frames and high-performance double glazing to combat Perth's extreme climate, from scorching summers to stormy winters. The result? Homes that stay cooler, quieter, and more energy-efficient year-round.
Thermally Broken Aluminium Frames
Our thermally broken aluminium frames are engineered for strength and elegance. With discreet sightlines and precision sealing, they deliver wide, uninterrupted views while locking in comfort. Unlike bulky alternatives, Penot frames balance modern aesthetics with outstanding insulation, so you don't have to choose between performance and style.
Installed with Care, Finished for Life
The difference isn't just in the glass, it's in the detail. Our experienced installers work to exacting standards, ensuring every frame is fitted for airtight sealing, smooth operation, and lasting durability. From heritage homes to new builds, we take pride in finishes that respect your architecture while transforming your comfort.
