In Firma Europrofil d.o.o. You can order the BLACKLINE XT subfolder box. This subfolder box for new buildings is characterized by high thermal and sound isolation characteristics. The box was created in cooperation with two German companies in order to meet increasingly stringent environmental and energy standards. It consists of high-quality materials of the combined characteristics of both companies. It has great adhesion on all profiles and has high stability in making. It is handy for operation because it can be transported separately from the window frames and can be mounted on the installation side apart from the windows.
Blackline XT features a stable connection between the box itself and the Exte XT with special adapters on all window profiles. Foam-free elements give stiffness and exceptional thermal insulation, while at the same time a good foundation for façade and plastering. On the outside there is a wrinkled EPS surface with which the plaster is easier to touch. You can or can not integrate an integrated mosquito in the interior. There are two options for revision of the box, which is a revision 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 window width.
