Solarlux Bi-Fold Doors in Surrey, Hampshire & Berkshire

Architecture has been enjoying a renascence over the last 10 years which has seen a growing desire to create larger living spaces centred around the kitchen. This trend has driven exponential growth in the popularity of Bi-Fold Doors.

Founded in 1983 and based in Bissendorf, Germany, Solarlux pioneered the modern Bi-Folding Door, designing and manufacturing the first system ever marketed and is still very much considered the market leader for high-quality Folding Sliding Doors and Glass Elements. Family-owned by the original founder, Herbert Holtgeife and his son Stefan, Solarlux continues to grow with the same passion and ideals that the company was built on.

Why is Solarlux Different?

If Aluminium Bi-Folding Doors are all the same then a Diamond is just another rock!

  • Solarlux designs and manufactures their own system meaning that every door they produce has been considered for its functionality and manufactured for its sole purpose.
  • As they are the only company to truly produce their own system, Solarlux is the only true German manufacturer. Every door shipped to the UK is completely produced in their factories in Melle making them truly German Engineered.
  • As all of Solarlux’s doors are produced in the same factory, every single door goes through the same manufacturing procedure. Therefore, all of their certification and CE markings can be attributed to all of their products without question.
  • Solarlux Doors achieve the highest level of testing and certification attainable in terms of product performance, security and weather resistance.
  • All of Solarlux’s systems are tested to 20,000 uses. If a door is used 13 times a week this is an average lifespan of 30 years!
  • The installation of Solarlux products is only carried out through authorised dealers who are specifically trained by Solarlux. The more experienced dealers become ‘Solarlux Quality Partners’ working on a higher level of training and product knowledge.

High Quality and Perfectly Tested Bi-Folds

Solarlux & Thames Valley Windows

Thames Valley Windows is a successful independent company which affords us the opportunity to work with almost any product we choose. Having worked with Sunflex and a variety of profile fabricators for a number of years, using systems such as Smart, SAPA, Beaufort, Schuco and Sunflex, we began working with Solarlux in 2010. It was very quickly apparent that the quality of their systems was considerably better than anything else we had worked with. After entertaining the idea of retaining a cheaper alternative we decided to focus exclusively on Solarlux as we feel that the price difference is significantly outweighed by the quality of the product. In 2011 we made this full commitment and have not looked back.

We’ve gone from strength to strength and our confidence in the product now means we have gone from a local company to covering most of the South & South East of England for our Solarlux installations. We are one of the two largest Solarlux Quality Partners in the UK and have been involved in some of the most prestigious Solarlux installations in the country.


Our staff, from technical sales and survey to installers, has been trained by Solarlux both in the UK and Germany.

Bi-Fold Doors will be one of the most expensive and defining features of your project. Be comfortable in the knowledge that you own the best product on the market.
