*subject to glass type and material thickness

There are three spacer options within the ThermoTech range.

Metal Spacer

Two pieces of glass are separated by a metal spacer and sealed to provide a hermetically sealed air gap. It has a primary water vapour proof seal and the secondary seal is supplied standard as polysulphide. Structural silicone secondary seal is an option upon request. The airspace is provided with a desiccant to prevent condensation forming within the unit.

Thermoplastic Spacer TPS®

TPS® is a butyl-based thermoplastic material. It is UV stable with integrated desiccant and applied directly onto the glass by a computer-controlled nozzle. This non-metallic spacer offers the ultimate heat insulation. In itself, it is an effective gas and moisture barrier. Units are supplied with polysulphide secondary seal as standard. The space is filled with argon gas as standard which further enhances the performance of the unit. Combine it with a silicone secondary seal and it is perfectly suited for structural glazing. Structural silicone is available as an option upon request.

Super Spacer

Super Spacer comprises a Thermoset structural foam containing no metal, an integrated 3A desiccant and an advanced multi-layer vapor barrier structure. It is a warm edge solution that minimises the transfer heat escape path for optimal performance.

Glazing compounds, sealants and gaskets need to be approved by Viridian for suitability.

Frame design - the Viridian Warranty relies on frame design in accordance with AS/NZS4666. Do not expose ThermoTech edges to standing water and moisture as this can result in seal failure. The frames must incorporate impervious weather seals or a self draining system.

Wind load and safety determine the type and thickness of glass required - refer Australian Standard AS1288 or New Zealand Standard NZS4223.

Installation must be in accordance with AS/NZS4666. Please refer to the technical glazing specification on the website for further installation instructions.

Visual characteristics and manufacturing tolerances - ThermoTech is manufactured to AS/NZS4666. Also refer to the Viridian website for specification and installation information, including distortion and reflection from changes in exterior and interior pressure and temperature.
