Renewable Energy - Double Roman Solar PV Tiles

Harnessing solar energy is one of the most attractive and sustainable means of generating zero carbon, renewable energy for use in buildings. The 2nd generation of Redland PV roof tiles now includes a system specifically for 50 Double Roman tiles.

Designed for performance, ease of installation and good looks, Redland Solar PV offers significant benefits in all three areas over "above the roof" panel systems, where poor installation can compromise the roof structure. More information can be found on the 50 Double Roman Solar PV Tile pages.
Authority and Double Roman Guarantees

50 Double Roman Tiles conform to BS EN 490: 2004 Concrete roofing tiles and fittings for roof covering and wall cladding - Product Specifications.

All of our products are designed and tested to work together. So not only is every product guaranteed weathertight, all the junctions between our products are similarly guaranteed. If any of our products fail due to weathertightness during their first 15 years, we will not only replace them, we will also pay for the cost of labour and associated materials. Besides guaranteeing the roof tiles, this guarantee includes all our fittings and accessories. Indeed, the guarantee is so comprehensive that it is transferable to all future owners. A complete Redland roof is a completely guaranteed roof.
Performance

Redland 50 Double Roman Tiles have been rigorously tested in our wind tunnel where combinations of high wind and driving rain are used to determine the tile performance with respect to wind loading and weathertightness. Tiles will meet all the requirements of BS 5534: 2003 Code of practice for slating and tiling (including shingles), providing our fixing recommendations are complied with.
