Vacuum Insulation Panels (VIPs) are ultra-thin, high-performing insulants that can be up to 20 times more effective than traditional insulation products.

VIPs provide energy efficiency and space benefits for: Buildings; Home Appliances; Refrigerated Transportation Systems, and Any other Applications requiring Low Energy Loss from heat transfer.

A Vacuum Insulation Panel consists of a rigid, highly-porous core material encased in a thin, gas-tight outer envelope. The envelope is evacuated and sealed to prevent outside gases from entering the panel. The combination of porous material and the vacuum results in an extremely high thermal resistance. The thermal resistance allows for thinner insulation in applications where space is at a premium.

Each structure has its inherent solid mechanical properties. The minimum density to withstand atmospheric pressure loads is distinctive. The same is valid for the centre of panel (COP) value for the thermal conductivity, which depends on the solid backbone of the core material. The core material should have the lowest possible thermal conductivity to ensure the VIP’s best performance.  

The thermal conductivity of a well-evaluated dry VIP with a fumed silica core is about 0.004 W/(m•K) after production. It is about 0.020 W/(m•K) at ambient pressure. By comparison, thermal conductivities of conventional insulation materials are typically between 0.030 and 0.040 W/(m•K). 

Vacuum Insulation Panels (VIPs) are used wherever space is limited and excellent thermal insulation is required. Lextherm has been pioneering the field since 2011 to help resolve difficult spatial design problems, and offers a range of products including cost-effective customized VIPs and heat & cold storage elements containing Phase Change Materials (PCMs).
