Turvac Si VIP

Advanced solution for space and volume limited solutions.

What is Turvac Si VIP?

Turvac Si VIP is a high-performance vacuum insulation panel designed for exceptional insulation at minimal thickness, making it the perfect solution for applications where thermal efficiency, space optimization, and durability are crucial. 

The synergy of fumed silica core at the heart of Vacuum Insulation Panel, integrated into metalized multilayer foil, evacuated to create a vacuum and minimize heat transfer, results in extremely efficient insulation technology.

Originating from fumed silica, a high-performance material produced through the pyrolysis of silicon dioxide, VIP core is engineered to redefine thermal insulation across diverse applications. The unique characteristics of fumed silica, such as its high surface area and low thermal conductivity, are harnessed to create a highly efficient insulating material. The nanoscale structure of fumed silica ensures excellent insulation and contributes to the overall lightweight and compact nature of the VIP.

VIP is classified as the most effective thermal insulation material on the market, in terms of thermal conductivity with lambda value λ < 0,0045 W/mK, at the center of the panel.

Technical Characteristics

of Turvac Si vacuum insulation panels

Core Thermal conductivity (COP) Standard temperature range Standard size Thickness Density
material W/mK °C mm mm kg/m³
Fumed Silica < 0,0045 from -70 to +80 from 160 × 160 to 1200 × 800  10 - 50 170 – 210 

Handling and storage

The envelope, metalized foil of Turvac Si VIP must not be damaged by drilling, cutting, milling, nailing, or any similar mechanical method, as this could compromise the vacuum integrity, resulting in the loss of its superior insulation properties.

The panels must be stored in dry conditions and protected from mechanical damage and direct sunlight.

Installation should be carried out on a clean surface to prevent mechanical damage to the VIP. If these conditions are challenging to meet, it is advisable to consider an alternative solution with an additional layer of protection such as XPS (Turvac Si Add ons), PIR (Deck-VQ), etc.
