Dufferin Stone is an innovative new
building material designed by Oldcastle APG, a European blue-chip company with
corporate headquarters in Dublin, Ireland. Avalon will be the first residential
development in the United States to offer this distinctive new product as a
standard building material. Dufferin Stone is a masonry veneer installed with
the same construction methods used to lay clay brick; however, the size and
shape of the stones allow homeowners to specify random ashlar patterns that
avoid the commercial look of traditional masonry.
In addition to the pattern flexibility, the
stones are produced with natural textures and superior color-blends to create
an old-world appearance that brings distinction to your home. These stones are
tested to endure extreme conditions of heat, cold, de-icing salts and acid rain
without fading, and will protect your home against the elements with the
soundness of concrete. With Dufferin Stone as an option for all elevations,
Avalon residents will enjoy the look and feel of natural stone with the
durability and quality-control of today's manufacturing techniques. Durable and
beautiful this stone veneer will add substantial value to your home that you
will be able to enjoy for years to come.
