SolTech¹ for Greater Thermal Control » Viridian Glass


Performance single glazing

SolTech¹ is a single glazed hard coat Low E product with a neutral aesthetic that is bluer in appearance, designed specifically to improve thermal insulation and solar control performance benefits combined with low visible light reflection and high light transmission.

As the pyrolytic hard coating of SolTech¹ is applied during the float glass process it is extremely durable and can incorporate additional processes after manufacture compared to soft coated products.

Due to the nature of the coating it can be exposed to the interior of a building to provide improved thermal insulation and can also be used as part of a laminated or insulated glass unit.

SolTech¹ is supplied in a range of clear, coloured and toned float glass types for design and solar control flexibility.


SolTech¹ is a registered trademark of Oceania Glass.
