The new double-walled, insulated and reclosable cable duct features an attractive design and is easy to open and close. It is ideal for situations where cables and/or pipes need to be routed through the roof at a later stage. The supplied adhesive base plate is double-walled and insulated, making it insensitive to condensation. In addition, a “barrier” is included, providing both an airtight seal and protection against the ingress of pests. The base plate can be connected in a vapour- and airtight manner and can be extended under the roof. The reclosable cap is made of PP, offering high strength and UV resistance.
