Vacuum glazing options for managing solar heat, insulation and outside noise, shaped around the needs of your space.

Discuss Control Explore the details

Vacuum glazing. A specification shaped around your project.

Modern bedroom with wide glazing overlooking a city at night — VGA range imagery

Solar Control

Vacuum insulation combined with a reflective coating. Published solar heat gain coefficient (SHGC): 0.40.

Heat Control

An insulation option with a published U-value of 0.4 W/m²K, designed to limit heat transfer through the glass.

Acoustic Control

Glazing for spaces where outside noise matters, with a published weighted sound reduction index (Rw) above 36 dB.

Technical information

The details that matter.

Selected figures from VGA product material. The final specification depends on your project and the glass configuration.

Before you specify

Solar, Heat and Acoustic Control are separate performance considerations. These published figures should not be assumed to apply together to every Control configuration. Confirm the selected glass and test basis with VGA.

Glass figures are not whole-window ratings. Final suitability, test documentation and any project approvals need to be confirmed.

Where it fits

Comfort shaped around your environment.

A sunny room, a colder aspect and a busy street place different demands on glazing. Control brings those priorities into the specification conversation, so the glass can be selected around the environment and the way the space is used.

Spaces exposed to strong sunlight
Homes requiring improved thermal insulation
Rooms affected by outside noise
Residential and specialist glazing projects

Coatings, daylight and reflection

The published range includes Basic Low E single-silver coating, Premium Low E D80 and a solar control coating. Each balances visible light, outdoor reflectivity and solar heat gain differently. The tables also preserve a separate set of laminated combinations.

Choose the coating around the room and its exposure, then confirm the performance of that exact combination. A lower solar heat gain figure should not be assumed to mean the same appearance or light transmission.

Construction details to confirm

The improved construction described for Control omits the evacuation plug and uses a linear getter close to the perimeter. The retained construction illustration shows an earlier arrangement with a port cap, so use the current product drawing when specifying.

A slim profile may help where glazing space is restricted. Installation, compatibility and maintenance still need to follow the current instructions for the selected glass and frame.

Using the reference figures

The original charts below are retained as published. They are reference material, not a substitute for the current specification or a test report for the selected glass and complete window. Confirm availability, construction and warranty with VGA before ordering.

Historical comparisons of energy efficiency, noise, light transmission and service life do not establish that one product is best in every application. Savings and installed performance depend on the project.

Construction diagrams and comparison charts · reference material

These original diagrams include historical configurations and comparisons. Some figures differ from the current range information. Read each caption and confirm the selected product’s documentation before specification.

The illustrated port and getter differ from the improved construction described above. Dimensions and coating comparisons in the image are not a current specification.

Thermal comfort illustration · reference — Historic illustration comparing a LandVac example at 0.6 W/m²K with insulated glass at 1.8 W/m²K. This is not the current Heat Control summary figure of 0.4 W/m²K. The depicted room temperatures are illustrative, not predicted project results.

Acoustic illustration · reference — Original comparison labelled LandVac Rw >36 dB and insulated glass Rw >29 dB. The depicted indoor sound levels illustrate the concept; they are not a test report or a promise of the noise level in a finished room.
