The increase of the polyamide thermal break strip for reducing the heat loss trough conductivity can generate a higher heat loss trough convection inside the cavities. In addition, the system can become mechanically unstable.
By dividing the chambers the heat loss through convection is reduced. The classic insulating strip is strengthened so that the system displays the necessary static support.
The package solution by Technoform Bautec: the labyrinth-shaped additional profile reduces convection. With an optimal system design Uf-values up to 1.4 are possible. Additionally the package solution gives the system stability, especially in the coating process.
