ISS is proud to offer the Armada Ultra. This slate comes from Southern Spain away from the more traditional slate quarrying areas and falls into our premium range.
The slate is very flat and uniform, making the Armada Ultra an easily workable slate and very practical for any roofer with the opportunity to work with it.
The Armada Ultra is a mid-blue grey slate offering a slight natural texture to its surface, neatly dressed edges and no visual inclusions.
As can be seen this premium slate look’s great when in situ offering its own unique charm and uniformity, whilst protecting your home for a life time.
The Armada Ultra is available in a 4mm thickness, making it ideal for Eastern England and London.
Ultra Grade slates are of the finest quality and are produced from specially selected blocks extracted from the quarry. Ultra-Grade slates give a superior finish in terms of flatness and uniformity with minimal sorting and grading needed on site prior to fixing.
Sizes Available: 500x250mm
The Armada Ultra slate boasts a W-1, T-1, S-1 rating, meaning it conforms and surpasses all the top UK tests for water absorption, thermal cycle resistance and sulphur dioxide exposure.
