Windmill Windows, For Double Glazing in Cornwall

Windmill Windows are one of Cornwall's premier installers of conservatories with their high quality uPVC Double Glazed Windows, uPVC Doors, Composite Doors and the Ultraframe roofing system.

A Rated Windows

They have just launched a new unique upvc 'A' rated energy efficient window which makes one of their conservatories the most energy efficient on the market.

All their doors carry a high security ten-point locking system and all their conservatory windows are fully reinforced for maximum strength and security.

They are a family owned and run business and have been trading for well over 20 years, employing their own qualified skilled fitters and not sub-contracting. Windmill Windows are also winners of a Customer Care Award from the Consumer Protection Association and their policy is to try to give their customers 100% quality and service.

A quality conservatory is one of the best home improvements which can be made, not only does it offer a comfortable extension to your living space, it can also add value to your home and make it easier to sell when that time comes.

They cover the whole of Cornwall from Lands End to Plymouth and the majority of their work comes from recommendations.

For total peace of mind, Windmill Windows are the company for you.
