Ashmore is a single lap, interlocking double plain tile. The hidden interlock offers ease and speed of installation and gives the appearance of traditional double lap plain tiles. Ashmore is designed to perform at pitches as low as 22.5°, providing outstanding performance and versatility. With fewer tiles required to attain the traditional plain tile appearance, Ashmore is also highly cost-effective.
- Quick and easy installation
- Performance similar to a large format interlocking tile
- Can achieve an A+ rating in the BRE Green Guide to Specification
- Certified Excellent for BES 6001
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).

The effectiveness of the tile or slate to operate at the minimum recommended pitch and lap may be influenced by special circumstances. Guidance on pitch and lap should be obtained from the Technical Advisory Service for the following:
Interlocking tiles and slates where the roof slope exceeds 6 metres in length and/or the site is rated to be in a severe exposure category. Double-lap fibre cement slates where the roof slope exceeds 6 metres in length (severe/very severe exposure) and 9 metres in length (sheltered/moderate exposure).
