Installation Steps on Wall Partition

Mark the building position with an inked string, according to blueprint. Secure the tracks on ceiling and floor by gunpowder nailing, and cut the studs into correct dimension, according to actual height. Insert the studs laterally into the tracks. Fix the boards on one side & fill in acoustic and thermal insulations. Seal boards on the other side, fill the joints. Painting or pasting wall papers.

Board Fixed

Firstly cut the board into the dimensions what needed. Board is fixed on keel in anchoring seam way topping screw: the interval of tapping screw is generally about 200-250mm with screws sinking 0.5mm under the boards face. The expansion seam of about 4mm between board should be kept. The shrouding should be fixed from the middle to the four sides and cannot be operated at multi-point simultaneously to avoid generating inners stress to make board material bucking. Before board being fixed, depending the needs, glass cotton or rock cotton can.
