Aerogels and vacuum insulation – the best modern thermal insulation
Is the VIP Deck -VQ vacuum board suitable for facades?
Yes, vacuum boards (VIP) are increasingly used in construction, including facades. VIP are modern insulating materials that use the good thermal insulation properties of a vacuum and are characterized by very good thermal parameters. Thanks to the best thermal properties of the core on the market, with a lambda coefficient of 0.006 W/mK, you can easily achieve even better thermal insulation in renovated or new buildings.
VIP boards are relatively thin, which saves space, while providing very good thermal insulation.
Vacuum insulation – a type of thermal insulation. Compared to commonly used materials such as polystyrene or mineral wool, vacuum insulation is characterized by several times better insulation parameters. These parameters are obtained by using a vacuum, which is a poor conductor of thermal energy. During the production process, a plate of porous silica material or glass fiber with micropores of 0.0001 mm is placed in a waterproof “packaging” made of a multi-layer film waterproof to air and water vapor. Due to its high price, this material is used only in special cases, e.g. in construction work. when it is necessary to obtain a wall that effectively protects against heat loss, and at the same time is thin.
In the case of facades, VIP panels are used as terrace insulation because they avoid creating a high step between the interior space and the terrace.

Nowadays, when energy efficiency of buildings is becoming a priority, engineers and architects are looking for innovative solutions that will allow to achieve high thermal insulation. One of the latest developments in this field is vacuum insulation, which is gaining more and more popularity in construction. In this article, we take a closer look at these advanced insulation materials, their parameters and their impact on the energy efficiency of buildings.
What is vacuum insulation?
Vacuum insulation is an advanced material whose structure is based on the principle of thermal insulation through a vacuum. Unlike traditional insulating materials, vacuum insulation uses emptiness, eliminating heat conduction through convection and conduction. As a result, we obtain a material with extremely low thermal conductivity.
Vacuum insulation is an advanced insulating material that uses the principle of thermal insulation through a vacuum. The main idea is to create a vacuum layer or a low-pressure area in the insulation structure, which minimizes heat transfer through convection and conduction. This allows vacuum insulation to achieve very low thermal conductivity values, which makes it effective in stopping heat flow.
A typical component of vacuum insulation is a core containing a material with low thermal conductivity, surrounded by a hermetic shell that creates a vacuum layer or a low-pressure area. This core is often made of materials such as silica dust or organic fibers, which are characterized by low thermal conductivity.
Compared to traditional insulation materials, vacuum insulation has significantly better thermal insulation properties, which allows for high energy efficiency in buildings. They also improve the thermal parameters of the structure, reducing heat loss and increasing thermal comfort inside the building.
Vacuum insulation is used in various areas, such as roof, wall and floor insulation, as well as in the refrigeration industry or the production of high-temperature devices. Their advantages, such as low thermal conductivity and the possibility of obtaining effective insulation with a relatively small thickness, make them increasingly popular in modern construction, especially in the context of energy-saving and sustainable projects.
Vacuum insulation parameters
1. Thermal conductivity
One of the key parameters of vacuum insulation is its thermal conductivity, marked with the symbol λ. The thermal conductivity values achieved are much lower than in the case of traditional insulation, which makes these materials exceptionally effective in stopping the flow of heat.
2. Insulation thickness
Due to their low thermal conductivity, vacuum insulation can be made much thinner than traditional insulation materials, which saves space and facilitates integration with various structural elements.
Thicknesses | Thermal resistance |
---|---|
45 mm | 5.00 |
60 mm | 7.50 |
3. Mass and volume
Vacuum insulation is characterized by low mass and volume, which contributes to the lightness of the structure, which is important both in new buildings and in the process of thermal modernization of existing buildings.
4. Durability and resistance
Good vacuum insulation is resistant to weather conditions, UV radiation and other factors, which translates into their long service life.
Application of vacuum insulation in construction
Vacuum insulation is used in various areas of construction, both in new buildings and in the modernization of existing ones. It can be used in wall, roof and floor structures. Their effectiveness makes them particularly attractive for energy-efficient buildings, passive buildings and in facilities requiring maximum energy efficiency.
Summary
Vacuum insulation is a breakthrough solution in the field of building thermal insulation. Their advantages, such as low thermal conductivity, small thickness, lightness and durability, make them an increasingly popular choice among designers and investors. However, as with any new technology, there is a need for further research and evaluation to thoroughly understand all aspects of their use in different climatic and structural conditions. However, vacuum insulation is a promising development direction in the field of thermal insulation, contributing to the creation of more energy-efficient and sustainable buildings.
