High safety levels characterize M20000 Apollo Alutherm and M20500 Apollo, which are also available in simple (M20500 Apollo) and thermo-break versions (M20000 Apollo Alutherm).
The system satisfies the highest requirements for safety since it allocates incorporated steal mechanisms that ensure perimetric frame locking in many points.
It is based on the applied and certified technology of M11000 Alutherm Plus.
