Non-Reflective Coatings

Non-Reflective Glass is used on numerous architectural glazing projects where the glass elements need to be as invisible and unobtrusive to the design aesthetic as possible.

This is usually more frequently the case on listed and heritage buildings. Glass is used in these scenarios due to its highly transparent nature and its ability to unobtrusively block in spaces without changing or damaging the original design intent of a building.

Low Iron glass is generally used in these areas but the use of a non-reflective coating is an additional option to further reduce the visibility of the glass units.

Non-Reflective Coatings are applied by dipping the glass panel numerous times into metal oxide solutions; these are cooked onto the glass at 400 – 500°C. Its the resulting lightwave transmission between the oxide layers that creates a non-reflective result.

This is a hard coating on the glass unit which means that it is incredibly durable against scratches or external chemical attacks (i.e in marine environments) and is maintained as a standard glass unit would be.

When a non-reflective coating is applied to glass units it can reduce the residual reflection to less than 1% and can offer a light transmission value of 98%.

Maximum sizes for these glass panels are determined by the size of baths that house the metal oxide solutions. Currently, the maximum size stands at 3770 x 1770 mm. Glass panels with non-reflective coatings applied can be laminated for structural glazing and be used in insulated double glazed units for use in a variety of applications.
