The VAX System - summary

The VAX system consists of an evacuated cavity - which contains a compression-resistant tensegrity structure - positioned between two outer airtight panels, which are joined by a continuous flexible airtight metallic foil seal at their edges.

The key VAX panel features are:

They are dynamic. The VAX Panels are connected by small diameter pipes to a central vacuum pump allowing the vacuum to be reinstated over time - so maintaining the high thermal and acoustic barrier performance for indefinitely long periods of time.
They can be folded flat. The VAX Panels have an internal membrane which allows the interior to fold down flat. This means shipment and storage costs of them are minimised. When flat-packed, the vacuum panels occupy 85% less space (i.e. only 15%) than conventional thermal insulation products of equal performance when stored or transported.
The tensioned internal material is basalt fibre textile-based. This heat- resistant material absorb acoustic energy, critical for sound barrier applications. The internal ribs are made from a basalt fibre/cyanoacrylate resin composite with high acoustic energy absorption (“lossy”) properties.
The semi-randomised spacing of internal structure. This further aids acoustic insulation performance by damping potential resonant sound frequencies.
The reflective finishes on both surfaces of the tension fabric. The material finish has a low emissivity, and reflects heat (IR radiation) in both directions. The outer panels can be made from a wide range of materials, e.g. Fermacell gypsum wallboard.

Possible VAX Panel Applications
The VAX system is suitable for applications where there are space constraints, and a need for high performance thermal insulation, very good lightweight acoustic barrier performance, or when a combination of all, or any two, of those three performance characteristics is required. Possible applications include:

Closely grouped urban dwellings, especially hotels and student accommodation. The ideal market within this segment will be those which use lightweight modular construction.
Cruise ship cabins, where fire-resistance can be demonstrated. This, however, is a relatively small market (compared to housing) and will require time-consuming approvals from the maritime performance classification agencies and insurance companies.
Shipping containers, especially those used for frozen or refrigerated products. Here there is an additional challenge in that the panels need to be able to withstand impacts, and a high level of wear and tear.
