Insulated Tunnel Box for Stacking Blinds, by CAJAISLANT®, part of the NES family and certified by Passive House. It features external access to the inspection panel with a bottom-opening system.
This product is assembled in the factory and custom-cut to size. It is manufactured through a highly industrialized process using Neopor® (40 kg/m³), which provides excellent mechanical resistance as well as outstanding thermal and acoustic insulation (λ = 0.031 W/m·K).
Its aluminum exterior profiles, along with the option to add static brackets, enhance window stability against wind loads. Additionally, the patented design of its interior profiles, connections, and side end caps—made of PVC, Neopor, and foamed PVC—ensures thermal bridge breakage.
