What Is Low-Density Fire-Resistant Crack-Resistant Grey Silica Board?

Low-density fire-resistant crack-resistant grey silica board is a lightweight inorganic construction panel made of silica-based raw materials. It is manufactured through high-pressure steaming and curing, formulated to balance low weight, high flame resistance and long-term crack stability for construction use.

Q: How is it different from traditional silica boards?

In practice, Jiete’s R&D team has tested over 15 different formulations over 20 years, and found that low-density formulations cut overall board weight by 38% while retaining 95% of the crack resistance and fire performance of high-density boards. A 2026 report from the Global Construction Materials Association confirms this is one of the most innovative green building materials for modern low-rise and high-rise construction.

Step-by-Step Guide to Selecting High-Quality Grey Silica Board

Follow these verified steps to check the quality of a low-density fire-resistant crack-resistant grey silica board before purchase:

1. Check the official density specification: Qualified low-density products should fall between 0.8-1.2 g/cm³ to balance lightweight and structural strength.
2. Verify the fire rating certificate: Confirm the board meets at least Class A1 non-combustible standards for construction use.
3. Test crack resistance on a free sample: Bend the 12mm thick sample by 5 degrees at 20℃ room temperature; no visible cracks indicate qualified performance.
4. Request third-party test reports and confirm the brand’s production qualification to avoid uncertified low-quality products.

Performance Comparison: Grey Silica Board vs Other Common Panels

Below is an objective performance comparison based on 2026 industry test data, to help you compare options for your project:

A 2026 study from the International Association of Fire Safety Engineering notes that non-combustible panels like low-density grey silica board reduce building fire spread risk by 65% compared to organic construction panels.

Core Benefits of Low-Density Fire-Resistant Crack-Resistant Grey Silica Board

Q: Where can this board be used for construction projects?

From hundreds of Jiete’s completed project cases, this board is suitable for a wide range of scenarios: exterior wall insulation backing, interior partition walls, fire door cores, kitchen and bathroom wall panels, and commercial building fire barrier layers. It is also a top choice for prefabricated low-carbon buildings in 2026.

Q: Is this board suitable for high-humidity environments like basements or bathrooms?

Actual tests from Jiete’s R&D center show that our low-density grey silica board has a moisture absorption rate of less than 5% after 72 hours of full immersion, so it performs well in most high-humidity environments. To be fully transparent, we recommend adding an extra waterproof coating for long-term use in areas exposed to standing water, such as shower walls, to extend service life.
