Description
A modern version of the roll profile seen on roofs throughout Europe for over 2000 years, the Double Roman offers all the functional benefits of today’s interlocking concrete tile technology.
All of our concrete interlocking tiles can achieve an ‘A+’ rating (the lowest environmental impact) in the Building Research Establishment’s Green Guide to Specification (* element ref: 812410007, 812410018, 812410049).
Accreditation to the BES 6001 framework standard for ‘Responsible Sourcing’ means that projects using our concrete tiles can now achieve extra credits under BREEAM and the Home Quality Mark (HQM). Click here to find out more.
