Double Glazing & Conservatories in South Wales

At Glamorgan Windows, we have been manufacturing and fitting high quality, energy efficient double glazing to homes throughout South Wales since 1990. We offer an extensive range of windows and doors in modern uPVC, sleek aluminium including popular styles such as slide and swing patio doors. We also specialise in full design and build services to create stunning conservatories, orangeries and bespoke glazed extensions.

If you're looking for more than standard double glazing, you'll be pleased to know that you can customise any of our products with coloured or wood effect frames, specialist and decorative glass, and accessories, to meet your requirements.

All our glazing products are 100% bespoke, designed for you, and made to measure for your home. But what our products do have in common is that they all incorporate thermally efficient glazing and the latest locking systems, for the ultimate in energy efficiency and security.

As well as precise and efficient installation, at Glamorgan Windows we also manufacture our products in our South Wales factory, so we can ensure high quality at a price you can afford. Our personal service and traditional craftsmanship will ensure your new glazing or home improvement will provide all the efficiency, security and style that you desire.
