Laying smaller format slates can be very expensive and time-consuming, but with Duo Edgemere you get the same visual impact with the ease of installation provided by standard interlocking tiles.

With only 9.7 tiles per square metre, Duo Edgemere is a single-lap solution that allows quick and easy installation, and is compatible with our full range of ventilation and dry-fix systems. With great performance at pitches as low as 17.5°, Duo Edgemere is versatile enough to be used on a wide range of roof types.

All of our concrete interlocking tiles can achieve an 'A+' rating (which has the lowest environmental impact) in the Building Research Establishment's Green Guide to Specification.

Accreditation to the BES 6001 framework standard for 'Responsible Sourcing' means that projects using our concrete interlocking slates can now achieve extra credits under BREEAM and the Home Quality Mark (HQM).

If you like the clean, precise appearance of Edgemere, but would prefer a smaller format slate, then Duo Edgemere could offer you the perfect solution.                                                      The addition of a mock bond down the centre of the tile, combined with a broken bond laying technique, creates this illusion with stunning results.
