Stunning And Suitable For Passive House Standards
The Cero III thermally insulated aluminium sliding door benefits from 40 years of Solarlux experience in customised glass solutions. Narrow sightlines of the Cero III make the differentiation between inside and out dissolve away. Like all Solarlux products, the Cero III is exclusively made in Germany.
Extensive research and development involved in the evolution of the Cero III has enabled large fixed or sliding elements, which can reach up to 6 metres in height and make up a total area of 15 m². The ultra-slim 34 mm profile sight lines offer a huge 98% daylight transparency, which, in turn enables spaces flooded with light and providing a feeling of airiness and grandeur.
Solarlux sliding door achieves Uw values of around 0.8W/m2k, suitable for passive homes subject to glass sizes and specifications.

What Our Clients Say

Ordered a door c/w side window for our porch, to match the existing windows that had been fitted by the builders when the house was extended. Easy company to deal with, whether by phone or email & a great job done by the fitters on the day. Everything went as planned & I am planning on using them again, for the next phase of works.
Chandra, Hove
I have had Velfac windows and external doors for 12 years. One window was not fitted properly by the developer (not Westcott) and had been leaking and needed replacing. The window was on a 4th floor flat and access difficult. Westcott were recommended by Dovista and Westcott worked timely from survey to order and then to sync with scaffolders dates to install. The guys had difficulty getting the frame up to 4th floor but they stripped it down and hoisted it up to the 4th floor. The job was professionally completed in a day. I am very pleased with the result and would recommend Westcott. Particular thanks to the boys who were all courteous and professional- Adam, Gavin, Matt and Andy. The office staff were always prompt with replies too. Thank you all.
Alistair, Haywards Heath
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.
