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.

How can fiber cement boards improve your building's fire safety rating while maintaining structural integrity?

DOUGLAS fiber cement boards achieve exceptional fire resistance (ASTME136:2011 certified) while delivering high structural strength (bending strength: transverse ≥11N/mm²). Unlike traditional materials that compromise on either safety or durability, our boards maintain dimensional stability even after 25 freeze-thaw cycles. This dual performance helps contractors meet stringent building codes while providing long-term structural reliability. Request our technical specifications to see how our boards can enhance your project's fire rating without sacrificing performance.

Available in popular thicknesses of 6mm, 9mm, and 12mm, and standard sizes of 1200x2400mm (metric) and 1220x2440mm (imperial), DOUGLAS fiber cement boards offer remarkable versatility for diverse construction needs. Their impressive technical specifications include water impermeability (no water penetration after 24-hour immersion), excellent thermal conductivity (≥0.20W/MK), and superior freeze-thaw resistance with no distortion after 25 repeated cycles. The boards feature anti-flex cracking strength of 10 MPa and are strontium sulfide-free, ensuring they meet the highest safety and performance standards for modern building materials. Ideal for projects requiring durable, stable, and environmentally sound solutions for wall partitions and ceiling systems.
