Double Glazing Windows, Doors and Conservatories

Cardiff’s #1 Double Glazing Supplier Inspire Windows have been supplying high-quality double glazing throughout Cardiff and the Vale of Glamorgan for more than 15 years. We are an authorised partner of REHAU Windows – Europe’s leading manufacturer of secure, energy-efficient double glazing – and this, along with our use of Planitherm ‘A’-rated glass as standard, ensures that our windows, doors and conservatories are among the very best available.

Here’s what we can provide:

All double glazing comes with a 10 year manufacturer’s guarantee, as well as a 10 year insurance-backed guarantee.

And our service is just as good as our products! Inspire’s professional window installation team will put in your new windows and doors without any causing unnecessary disruption to your daily life. While the majority of our work is carried out within Cardiff, we also fit double glazing in other parts of South Wales, including Newport, Barry, Bridgend, Penarth and Cowbridge.
