PassivGlas™ Vacuum Glazing Retrofit
The most cost-effective solution to consider when upgrading and future proofing commercial properties, is to contemplate whether there is the option of replacing just the glass.
PassivGlas™ vacuum insulated glazing is a cost effective and viable solution as a replacement for outdated window glazing in buildings used for business purposes.
Replacing the glazing alone into existing frames, with thermally efficient (Ug – value of 0.49W/m2K) and sound attenuation of (Rw: 36 dB) can transform the internal ambiance with minimal disruption from the installation process.
VIG Installations Made Simple
The beauty of PassivGlas™ VIG units, alongside its impressive thermal and acoustic performances, is it is a versatile glazing product offering whilst also being a cost effective and sustainable, straightforward solution.
With thicknesses ranging from 6.15mm in single PassivGlas™ VIG’s and 20 mm in PassivGlas™ Ultimate, (a Single VIG with an air filled thermally broken spacer and another glass lite to offer an IGU thickness triple glazed unit.) our glass can be installed into many kinds of commercial properties to create environments with high natural light, whilst maintaining a comfortable internal environment.
Why Choose Vacuum Glazing?
Vacuum glazing is a thinner insulated glazing unit, where the air gap has been replaced by a thermally efficient vacuum. This third generation glazing technology, reduces heat transfer due to the vacuum and a Low-e coating on the glass, and therefore translates into greater control of the internal environment of the building, reducing reliance on temperature control solutions.
PassivGlas™ vacuum insulated units, offer a Ug-value from 0.49 W/m2K making it more effective at heat insultation than even gas filled triple glazing. Additional benefits include an impressive noise suppression (Rw:36 dB). Both qualities can reduce distractions and offer a relaxing city working environment.

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.
