"The slider market has increased
33% over the last three years
against a decline of 15% in the
first time replacement
casement window market,"
says Steve Cross, Joint Director
of Mercury, which makes 200
Spectus sashes a week.

"It's a major opportunity for
installers and fabricators but
you need to have the right product
and strong support throughout
the supply chain. Many of our
customers are fabricators who
buy-in - manufacturing sliders is
a big investment and very
different to making casements.

As an established sash specialist
we're helping them make the
most of this market."

Steve explains Mercury's growth:
"We've only ever fabricated the
Spectus sash because it's the
best available and the support
is second to none.
