FAQs
Can I install aluminium French doors with side windows?
Yes! We offer French doors with side windows, allowing for even more natural light and a wider glazed area. This is a great option for larger openings, kitchen extensions, or patio entrances, maintaining the slim sightlines of aluminium while making the most of the view.
Are these doors suitable for period properties?
Absolutely. Our Alitherm Heritage range is designed to replicate traditional Crittall-style doors, making them an ideal replacement for steel doors in period homes, renovations, and conservation projects.
How long does installation take?
Installation can take as little as a few days, depending on the size and complexity of the project. Our FENSA-certified installers work efficiently to ensure a seamless fit, leaving your home clean and tidy when the job is done.
Do aluminium French doors require a lot of maintenance?
No. Aluminium is naturally resistant to rust, warping, and fading, making it low-maintenance compared to timber or steel doors. To keep them looking and performing their best:
- Wipe down frames with mild soapy water to prevent dirt build-up.
- Check locking systems periodically to ensure smooth operation.
- Lubricate hinges and handles annually for seamless use.
With a 10-year guarantee, you can enjoy your new doors with total peace of mind.
