Sapphire Glass Merchants Ltd has won a £1.4 million contract to supply slim, low sightline insulated glass units to Lithuania using Super Spacer Heritage manufactured by Edgetech, a Quanex company. The Lithuania contract follows another substantial order of 1,500 Super Spacer Heritage units to Compass Windows in Northern Ireland.

“Due to the significant increase in sales for slim Super Spacer Heritage units, we have now introduced the product to all of our customers and had a fantastic response in sales,” says Stefan O’Meara director of Sapphire Glass Merchants.

“There is a growing demand for warm edge products that can be used in conservation areas or to achieve a traditional look and the slim 4mm option from Super Spacer Heritage works really well. The architect for the Lithuania project saw a Super Spacer Heritage installation we had recently finished in Pimlico and specified the product.”

The neutral appearance of Super Spacer Heritage and 3mm depth for ultra slim sightlines help it to blend with any frame finish. It facilitates the use of Low E glass double glazing where there was previously only space for single glazing, reducing U-values from typically around 5.6 W/m²K to below 2. The acrylic adhesive and multi-layer vapour barrier backing on the pre-desiccated silicone foam spacer are combined with Bostik 5000 hot melt butyl secondary sealant supplied by Edgetech to provide outstanding durability and gas retention.

Stefan adds: “We’ve been customers of Edgetech for five years now using its Super Spacer products and started using the Heritage product two years ago. Working with Edgetech to supply Super Spacer Heritage has helped us to win two key contracts this year and we’re now hoping to expand in the New Year with a second Super Spacer line.”

“Speaking to customers, standard aluminium or warm edge spacer bars can intrude over the low bead line of traditional style windows. Super Spacer Heritage reduces the sightline to eradicate the problem. We’re also hoping to add more colour options in the New Year,” says Alan Fielder, sales and marketing director at Edgetech. “We’re pleased to be supporting a long-standing customer in winning some great contracts.”
