According to GED Integrated Solutions, the success of the Intercept spacer system, on the market with more than 600 million units installed, is mainly attributable to the U-shaped design of the metal spacer that allows superior flexibility when compared to any other type of spacer.

The flexible side walls of the U channel in the Intercept system move freely with rises or falls in temperature, yet its design means that the base of the U channel retains a strong and constant bond with the sealant at all times. This means that, with virtually no load placed on the sealant, seal failures are nearly eliminated.

Intercept also has the longest moisture vapour transmission path of any spacer system, providing the most durable seal to keep moisture penetration firmly out.

These attributes, coupled with four-layer ‘Quad-Corner’ protection as its corner seal, means Intercept has the highest rated argon gas retention of all with a loss rate of less than 0.01 per cent a year.

Where typically a sealed unit manufacturer will guarantee its product for 10 years, one Intercept system manufacturer in Manchester is so confident of the outcome that it offers Intercept units with a 25-year guarantee as standard.

There are other advantages, including the ready acceptance of the Intercept visual aesthetics by both sealed unit manufacturers and the householder alike, both already familiar with metal spacers between panes of glass.

Intercept patent holder PPG’s manufacturing partner GED has devised its i3 technology with plant-wide software integration specifically to increase output, decrease labour and produce cost savings in manufacturing of, typically, £2-3 per unit.
