Thames Valley Windows offers architects and contractors a comprehensive range of the best bifold door systems designed with the latest advancements that provide outstanding thermal performance suitable for high-end residential and commercial projects.
We have been designing and installing architectural glazing solutions throughout the South East for nearly 40 years. As an independent family business, nothing is more important than our reputation and standing by our values and service.
We pride ourselves on customer satisfaction and building lasting relationships with our customers based on ethics, trust, and honesty. We take time to listen to our customer’s needs and take them on a journey that goes the extra mile. Many have purchased multiple windows and doors from us and continue recommending us to family and friends.
We have built our reputation as experts in the glazing industry thanks to our dedicated team of designers, surveyors and installers.
We enjoy and love what we do and have an abundance of experience in the glazing industry that enables us to manage projects, large or small, of varying scale and complexity. We ensure the whole project is managed smoothly from beginning to end, and we are confident that we can meet and exceed your expectations.
Bifolding doors are often one of the wow factor features of the glazing package for any project. The ability to give a 90% opening is a significant benefit over sliding doors. With the doors stacked to one end, the space does open up to the outside and will often give the ‘WOW’ factor. We can also offer cornerless and glazed corner solutions for those who want to maximise ‘bringing the outside in!’
Here at TVW, we are well-poised that we can meet and exceed your expectations. We have innovative design options to suit every project and cover a range of budgets.
Each system is meticulously engineered to satisfy even the most demanding site conditions and requirements, pushing the boundaries of modern architectural design.

Combiline Timber/Aluminium Bi-Folds are aesthetically pleasing and luxurious hybrid door systems.
They are available in sustainably sourced meranti, spruce, oak and pine, adding natural warmth and character to your home.

Definitely worth considering if you have composite windows elsewhere – e.g., Internorm or Rationel.
