This sub-facade box for new buildings is characterized by high thermal and sound insulation characteristics. The box was created in cooperation between two German companies in order to meet the increasingly strict standards of ecological and energy installation. It adheres perfectly to all profiles and has high stability in production. It is practical for work because it can be transported separately from the window frames and can be mounted on the installation object separately from the window. Blackline XT features a stable connection between the box itself and the Exte XT guide with special adapters for all window profiles. Neopor foam elements provide strength and exceptional thermal insulation, while at the same time they are an excellent base for facade and plastering. On the outside, there is a corrugated EPS surface to which the plaster adheres more easily. You may or may not have to install an integrated mosquito net in the interior. There are two options for inspecting the box, namely an inspection from below and from the outside, where you access the interior by opening the PVC cover and removing the Styrofoam insulation. Internal revision is possible up to 92 mm wide window profile.
