Ductwork Passing Through Ashbond Partitions
Ductwork may pass only through 10 cm-thick Ashbond partitions, with a maximum duct diameter of 40 mm. Larger ducts require special coordination with the Ashbond Technical Department. Channels for water, electrical, gas, and communication lines must be cut using a hand-held milling tool with the appropriate bit size. Quarry hammers must not be used for cutting channels.
Water Pipework Installation
Water pipes should be installed in Ashbond partitions according to all relevant standards and practices. The use of various types of plastic pipes is recommended, following manufacturer guidelines. When using galvanized pipes, ensure they are gripped without damaging the galvanization, both before and after applying hemp. After positioning the pipes but before final securing, it is recommended to coat them with fast-drying asphalt paint to cover any unnoticed flaws.
Openings for Power Outlets
Holes for power outlets shall be prepared prior to cutting the channels for the ductwork, using a cup drill bit with an outside diameter 5 mm. larger than that of the electrical box, the central leading bit protruding beyond the cup by approx. 10 cm. The material filling the electrical outlet opening shall be removed from the partition using a hand chisel. When the channels cut out for the electrical ductwork are completed, the electrical box shall be mounted on the partition with Ashbond mortar applied to its exterior surface.
Covering of Water and Electrical Ductwork
Following installation of the ductwork within the Ashbond partition, the work should be temporarily anchored by devices such as wooden pegs. The channel is to be blocked and the ductwork covered between anchoring points using Ashbond mortar. After 24 hours, a wide spatula or trowel should be used to apply an additional layer of mortar to zero height for final filling, levelling and smoothing.
