Experiencing the vast variety of textures and colours that our roof tiles provide up close can guide you in the decision-making process when selecting roof coverings. Our efficient sample service can help you in this process.
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 and 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).
