Glazing Options

Glazing options have become more popular over the years.

The glass, as described in building regulations, states that any glazing below 800mm needs to be toughened.  From a safety point of view, any exposed edges need to be polished.

A general thickness of glass would be 10mm.

Another technical detail would be the colour of the glass.  In general the thicker the glass the more of a ‘green tint’ appears.  As an alternative, a ‘low iron’ or ‘ultra white’ glass can be used giving a more clearer appearance.
