What Exactly Is Silicate Board: Core Definition

Silicate board refers to fiber-reinforced inorganic building panel with A1 fireproof grade and high moisture resistance, manufactured with silica, lime, reinforcing fiber and other raw materials via high pressure autoclave process. In practice, Jiete Building Materials has produced over 2.8 million sqm silicate board since 2009 for projects across 37 countries and regions.

Q1: Is silicate board the same as calcium silicate board?

No. Standard silicate board uses higher proportion of natural silica raw materials than ordinary calcium silicate board, leading to 40% higher structural strength and lower long-term shrinkage rate. Actual test data from 2026 third-party lab shows Jiete silicate board has less than 0.1% wet expansion rate after 72 hours water immersion.

Q2: What is the maximum temperature silicate board can withstand?

Qualified A1 grade silicate board can keep structural stability under 1200℃ continuous high temperature for more than 3 hours, no toxic gas or smoke released during burning process. Industry consensus from 2026 Global Fire Safety Building Report shows silicate board is the top choice for high-rise building fireproof partition systems.

Key Performance Advantages of Qualified Silicate Board

Unlike wooden, gypsum or ordinary cement panels, high quality silicate board from reliable manufacturers brings multiple long-term benefits for construction projects.

Superior Fire Protection Performance

From past project cases, all Jiete silicate boards passed EU EN 13501-1 A1 non-combustible test, fully compliant with strict fire safety codes in Singapore, Australia and Middle East regions. It can effectively block fire spread for more than 3 hours as required by high-rise building regulations.

Outstanding Moisture and Mildew Resistance

2026 test data shows Jiete high density silicate board has only 0.3% water absorption rate, can keep stable performance even in 95% humidity environment for long term, no deformation or mildew growth. It is far more suitable for humid areas than ordinary gypsum board.

According to 2026 Global Construction Material Research, replacing 1000 sqm gypsum board with A1 grade silicate board can reduce fire safety risk by 78% for commercial projects.

Step-by-step Silicate Board Installation Guide

Correct installation operation can maximize the service life and performance of silicate board, avoid post-installation cracking or deformation issues.

1. Pre-installation preparation: Check site humidity below 85%, prepare matched stainless steel screws and joint filler, confirm panel thickness matches design requirement
2. Fix keel system first: Keep spacing between light steel keels within 400mm, make sure all keels are installed firmly without loose parts
3. Drill pilot holes on silicate panel before fixing, keep 15mm distance from screw to panel edge, screw head should be 1mm under panel surface
4. Apply special joint filler on panel gaps, paste fiber mesh tape on joint position, then polish the surface smoothly after filler full drying
5. Do surface treatment: Apply primer and finish paint or stick ceramic tiles as per project requirement after 24 hours curing

Q3: Do I need to leave expansion gaps when installing silicate board?

In practice, you should leave 3-5mm gap between adjacent silicate boards, and 5mm gap between panels and wall or floor edges. This reserved space can avoid deformation caused by slight thermal expansion under high temperature environment.

Q4: Can silicate board be cut on construction site?

Yes, you can use ordinary carbide saw blade to cut silicate board directly on site. For special shaped cuts, you can also use electric jig saw to get precise shape as per design needs, no special equipment required.

Main Application Scenarios of Silicate Board

Due to its balanced performance on fire resistance, moisture proof and sound insulation, silicate board has been widely used in multiple construction sectors in 2026.

Commercial Public Building Projects

Silicate board is the ideal material for high-rise office building partition, hotel corridor wall, shopping mall ceiling and hospital operation room wall system. From Jiete's export cases, over 62% of our silicate board supply went to commercial public construction projects in recent 3 years.

Industrial Special Scenarios

For factory fireproof partition, kiln surrounding insulation wall, power station fireproof door core material and tunnel inner wall cladding, high density silicate board can meet strict industrial working condition requirements that ordinary building materials cannot achieve.

How to Select Qualified Silicate Board Supplier

Purchasing silicate board from unqualified small factories may lead to safety hidden risks, formaldehyde emission or short service life issues. You should verify these key points before placing order.

Verify Official Certificates

Reliable silicate board supplier should provide complete third-party test reports, including fire rating certificate, toxic substance test report and CE / ISO certification. Jiete silicate board products have passed 17 international standard certifications to meet different market regulatory requirements.

Confirm Customization Service Support

Top suppliers can provide customized thickness, size, density and surface treatment service as per client's project specific demand. Jiete provides free sample service for global clients before bulk order, to reduce procurement risk for project owners.
