Burlington blue/grey is a 350 million year old sedimentary, metamorphic British slate, quarried in Cumbria, which has been used for over 500 years and offers a lifetime of service to the buildings they adorn.
Burlington blue/grey slates have been used for centuries on projects where clients and their architects have sought a material that is both functional and beautiful, and that allows them to make a statement of quality and permanence.
Traditionally produced in random lengths and widths the slates were laid in diminishing courses with the largest slates used at the eaves and gradually smaller sizes laid working up to the ridge. This tradition of laying slates in diminishing courses gives a distinctive visual perspective to the roof and slates are still produced in this format today. Slates can also be supplied in a sized format (fixed lengths with random widths) which helps to retain a traditional random element to the roof design, whilst speeding up the laying process and keeping the cost of installation down. For a regular half bond pattern to the roof, slates are available with a fixed length and fixed width.
Burlington blue/grey slates are available in three different grades: bests, strongs and extra strongs.
