The entry point to the Solarlux sliding door range — clean aluminium profiles, a uniform 55mm sightline at the panel joint, and a built-in cascading drainage system within the threshold. The Ecoline S handles panels up to 2,700mm wide and 2,500mm tall; the Highline S steps up to 3,200mm x 2,800mm for larger openings. Both are available in any RAL colour.
Where the sightline almost disappears. The Cero II features a 34mm aluminium profile — making up 98% glass by area — with panels reaching up to 4 metres tall and a total area of 12m². The result is a sliding door that dissolves the boundary between inside and outside. Made exclusively in Germany, and available in any RAL colour.
The Cero III takes the Cero II further — taller panels up to 6 metres, a maximum area of 15m², and the same ultra-slim 34mm profile with 98% daylight transparency. Uw values of around 0.8 W/m²K make it suitable for Passivhaus projects subject to glass sizes and specification. Made exclusively in Germany.
The flagship of the Cero range. The Cero IV takes the minimalist profile to its logical conclusion — top and bottom sightlines of just 15mm and a vertical sightline of only 2mm, achieved through structural glazing. All the thermal performance of the Cero II and III, with a frameless glass effect that has to be seen in person to be appreciated.
Maximum light meaning the system is perfect for those looking to completely erase the boundary between the inside and outside of your home.
High-quality stainless steel track rollers and rails which in addition to running smoothly, is also non-wearing and requires minimal maintenance.
Vertical glazing turns a glass canopy into a glass house that will protect you against all types of wind and weather.
Versatile glass elements provide additional protection from draughts without obscuring your view.

Westcott provided the windows for my new house and they are superb. I have called them out several times to make minor adjustments and most recently to repair a large triple glazed window that I carelessly smashed. The men who came are universally charming, Proffesional and fix things with great professionalism. Thank you this time to Ryan, Adam and Tommy for sorting things, but also Josie and Micki for organising it.
We were very impressed with Composite Window’s professional service. They are knowledgeable about their range of excellent products and keen to match competitor prices. The showroom in Portsmouth is very useful for seeing the quality of the doors and windows and, of course, meeting the team!
What makes this company stand out is outstanding customer service from start to finish. I had VELFAC 200 Energy windows installed for a new self-build so attention to detail was paramount. Composite Windows came to site multiple times before, during and after fitting to ensure the product was perfect. When one of the larger units was difficult to close, they sent their engineers to adjust it but still determined it wasn’t perfect, so replaced the entire unit. Its the service we all would hope companies strive to deliver but we typically settle for less. Composite windows really did deliver on my project. They have a great team in the office and at site. I would definitely use them in subsequent projects.
