The built environment is demanding more thermally efficient building envelopes, and it is becoming more challenging to achieve local regulations with single glazing. Viridian ClimaTech™ offers quality entry level performance double glazing for spaces which require additional insulation.

Suitable for hot and cold climates, Viridian ClimaTech™  provides increased thermal performance for residential and commercial window applications.  

Thermal Comfort with ClimaTech™

Viridian ClimaTech™ uses two pieces of glass, one coated with a spectrally controlled Low E coating and the other an ordinary clear or toned glass. Providing added comfort and design flexibility.
