Technical Details

Why Prefix Studio?

The Prefix WARMroof® and WARMwall off-site constructed building concept started over 10 years ago with the Prefix WARMroof® now firmly established as the industry’s leading, award winning solid roof system. Now, we are preparing to bring the enhanced version of the WARMwall to market utilising the same proven technology from the WARMroof system. The imminent launch of the Prefix Studio will see both the WARMroof & WARMwall working seamlessly together to create a range of off-site constructed Garden Rooms.
