In-House uPVC Manufacturing – Built to Last

We’re proud to manufacture all of our uPVC windows and doors in-house at our Ammanford factory.
This allows us to maintain complete control over quality, precision, and sustainability – from design to delivery.
Our experienced surveyors ensure each project is measured accurately before fabrication begins, and every uPVC frame is crafted using state-of-the-art technology and eco-friendly materials.

💬 Our uPVC products are made by us, fitted by us, and built to last.
