Specialist trade fabricator, Mercury Glazing Supplies, has agreed a three-year supply extension with Epwin Window Systems to manufacture its vertical sliding sash window system.

Mercury is reported to be Epwin’s longest standing vertical slider customer.

Steve Cross, co-founder and director of Mercury, said: “Our partnership with Epwin stretches back over 20 years and we are pleased to be extending it. We choose to continue manufacturing the system because it’s a market-leading sash window solution from an industry-leading systems house.”

Katrina Earl, sales director at Epwin, said: “Mercury was one of the first fabricators to manufacture the Spectus vertical slider system way back in 2002 and we continue to value their business today as much as we did then.”

The vertical sliding sash window system from Epwin was one of the first PVC-U vertical sliders to be introduced to the market. According to Epwin it combines authentic heritage aesthetics and outstanding thermal performance.

Mercury manufactures the welded and mechanically jointed versions of the system.

Steve concluded: “The vertical sliding window system is the perfect example of a product that continues to raise the bar in sash window design. Here at Mercury Glazing we are committed to doing the same. It’s helped to build a robust partnership that we’re proud to be continuing.”
