6 mm Calcium Silicate Board: Buying Guide & FAQs
6 mm calcium silicate boards are lightweight, high-strength, and fire-resistant building materials commonly used for partitions, ceilings, and other insulation applications.
They are manufactured from calcium silicate with reinforcing fibers, offering durability, dimensional stability, and excellent thermal performance.
This FAQ buying guide provides detailed insights into key specifications, installation tips, handling precautions, and common questions about 6 mm boards — helping you make informed choices when selecting the most suitable type for your project.
Table of Contents
What is the common installation method for 6mm calcium silicate boards?
Typically installed using the dry-hanging method, which involves fixing with metal studs and screws, suitable for partition walls and ceilings.
If the wet adhesive method is used, it should be paired with fireproof adhesive, structural adhesive, and similar bonding materials.
It is also recommended to leave expansion joints during installation to avoid deformation or cracking caused by thermal expansion and contraction.
What should be noted when transporting 6mm calcium silicate boards?
Use wooden pallets to keep the boards off the ground and avoid placing them on their side to prevent deformation or breakage.
Carry with two people to avoid dragging.
Since 6mm boards are relatively thin and prone to bending, extra care should be taken to protect the edges and corners.
What are the storage recommendations for calcium silicate boards?
Store in a dry, well-ventilated indoor environment, avoiding direct sunlight and rain, to ensure stable performance.
Is the 6mm calcium silicate board easy to break?
As a thin board, it can break if handled improperly or if uneven force is applied during installation. It is recommended to have two people carry it and keep it in a horizontal position.
Can calcium silicate boards be used outdoors?
Yes, but it is recommended to choose water-resistant reinforced calcium silicate boards and apply surface coating protection to extend their service life.
Do calcium silicate boards contain asbestos?
Compliant products are asbestos-free and environmentally friendly, containing no asbestos and being safe to use.
