Elterwater
Product Data Sheet
|
|
Elterwater stone is a pale green stone, often highlighted by contrasting veins which emphasise its natural origins.
Elterwater stone has been used for generations to provide walling, flooring, roof coverings, cills and copings. Architects and designers around the world have long taken advantage of its natural beauty, durability and adaptability to create classic weather resistant details and surface finishes. The richness of Elterwater stone makes it ideal for use in interior furniture and fittings, whether in traditional or modern design schemes.
Design guidance, details and sample clauses for the specification of Elterwater stone are available in a series of Burlington brochures.
Burlington can supply Elterwater stone in a variety of smooth and textured finishes (sample cards showing the finishes are available from Burlington).
