Hard-coat Low 'E' glass versus Soft-coat Low 'E' Glass
Hard Coat Low 'E'
A glass product that is coated during the molten glass stage of the manufacturing process. A pyrolytic coating is applied and offers a surface that is generally as durable as an ordinary glass surface. Hard coat Low 'E' does not require special handling requirements during manufacture.
Soft Coat Low 'E'
A metallic 'sputter' coating is applied to the glass as a secondary process, usually to offer high low-emissivity or solar control benefits. Soft-coat Low 'E' glasses generally requires some additional care in handling during manufacture and must be used within an insulating glass unit.
Phase Developments offer soft-coat Low 'E' sealed double glazed units as standard. Neutral Plus 1.1 soft-coat sealed units give a 'U' value of 1.1w/m2k when gas filled, one of best energy efficient ratings for double glazed units
