As Double Glazing has a finite life span the quality of manufacture and testing standards are of critical importance when choosing a supplier. Metro Performance Glass Double Glazing units are regularly tested by Branz compliant to EN1279.
Metro Double Glazing units are Insulating Glass Units manufactured and sealed in the manufacturing process. They consist of two panes of glass separated around the edges by a spacer and sealed at the perimeter in factory-controlled conditions. The spacer contains a desiccant-drying agent, which absorbs moisture vapour in the cavity.
Metro Double Glazing units are dual seal units comprising a primary seal of Polyisobutylene (PIB) to the spacer face and a secondary perimeter seal of Polysulphide. This results in a high quality unit with a 10 year warranty suitable for commercial and domestic applications.
