PassivGlas™ Ultimate

PassivGlas™ Ultimate, is an advanced fenestration technology that involves creating a hybrid highly insulating glass unit by enclosing a single PassivGlas™ Linear VIG with a thermally broken spacer bar and an additional pane of glass. This delivers further improved thermal performance when comparing against a standard A-Rated insulating glass and even gas filled triple glazing. It can be fitted into new or existing timber, aluminium or UPVC frames and can achieve Passive House Standards

PassivGlas™ Linear, a third generation vacuum insulated glazing (VIG) product, offers a flush surface as there is no evacuation port. Combining this with translucent micro-pillars, it offers architects a thermally efficient and acoustic high performing insulated glass with no visual restrictions.

PassivGlas™ Ultimate, utilising a Low-e coating on surface #2 and combining this with a 0.15 mm low pressure vacuum, which due to there being no air present, controls heat transfer. Typically, the heat gain and heat loss of a standard insulating unit is 70% of through Conduction and Convection.
Centre pane- U values:

• 24 mm unit: 8.15mm VIG -12 Air – 4T – 0.49 W/m2K
• 28 mm unit: 10.15mm VIG – 12 Air – 5T – 0.49 W/m2K
• 30 mm unit: 12.15mm VIG -12 Air – 6T – 0.47 W/m2K

Frequently Asked Questions

What are vacuum units?

Vacuum Insulated Glazing or VIG is an advanced fenestration type of insulating unit. It consists of two glass panes, like a standard Insulating unit, but rather than the spacer bar and an air gap, VIG’s are separated by a micro vacuum gap, with a glass solder edge seal.

Are they fully tested?

Yes, they are tested to recognised industry standards:
Impact resistance: EN 12150-2 & ANSI Z97.1-37 & EN 12600 & BS356 (recently completed)
Weathering: EN1279-5 & ASTM E546/E2188/E2189
U-Value: ISO8301/EN12667 (Recently UKAS tested) & ASTM C518
Soundproof: ISO 10140-2 (Recently UKAS tested)

Do the standard units use coated glass?

Yes, all PassivGlas™ Linear units incorporate a Low-e single silver toughenable coating.
In order to meet the current Part O regulations, a Low-e double silver coating would be needed to meet the 70/40 requirements. Please check with VGN as to availability and MOQ for this product range.

What is the expected life?

Expected life on the unit is 25+ years due to there being no spacer bar to fail.

Will there be any condensation

Condensation is formed when the air temperature surrounding an object falls below the dew point and changes into a liquid
Internal:
Although condensation will not form on the internal surface of a VIG unit, Vacuum Glazing does not eradicate condensation from the room.
The warmer inner glass will potentially change the rooms cold point.
It is advisable to ensure all rooms have effective ventilation/circulation.
External:
Condensation may form on the external glass surface under certain conditions.
Generally, forms a grid around the micro-pillars.
Will disappear when the outside temperature warms with the morning sun.
It is an indication of how efficiently your windows are at reducing thermal loss.
Condensation between glasses:
An indication that the Vacuum has been lost.
Consult your supplier to confirm course of action.
