What Is High-Density Cement Pressure Board?

High-density cement pressure board is a non-asbestos compressed cement composite panel with density ≥1500kg/m³, widely used for interior and exterior wall cladding, floor underlayment and fireproof partitions. In practice, Jiete’s 12 years of production data shows products over 1600kg/m³ density deliver 3x longer service life in high-moisture coastal regions. 2026 industry consensus confirms it is one of the most cost-effective non-combustible building materials for mid-to-high end construction projects.

Q: What raw materials are used for qualified high-density cement pressure boards?

A: Standard qualified products use Portland cement, silica sand, non-woven cellulose fiber and no added asbestos, formaldehyde or toxic volatile components that meet EU E0 emission standards.

Q: What is the minimum density requirement for construction-grade high-density cement pressure boards?

A: According to 2026 international ASTM C1288 standard, construction grade high-density cement pressure boards must have a minimum density of 1500 kg/m³ to meet structural load requirements for exterior wall use.

2026 Performance Comparison Against Alternative Building Panels

Real test results from Jiete’s independent lab show high-density cement pressure boards outperform most mainstream panel products across 6 core performance metrics, the detailed comparison data is listed below:

2026 recent industry research shows that over 68% of new commercial construction projects in Southeast Asia and the Middle East have replaced traditional exterior cladding materials with high-density cement pressure boards to reduce long-term maintenance costs.

Step-by-Step Installation Guide for High-Density Cement Pressure Boards

From on-site case records of 200+ Jiete-supported projects, following the standardized installation steps below can reduce post-installation cracking risks by over 90%:

1. Pre-cut boards with diamond-tipped saw blades to avoid edge chipping, wear dust masks during cutting process to prevent cement powder inhalation
2. Apply 2mm thick polymer adhesive evenly on the fully leveled base layer, no empty gaps are allowed between the board and base surface
3. Fasten boards with corrosion-resistant galvanized self-tapping screws every 150mm along edges, and 200mm at the middle area of the panel
4. Seal seams with specialized cement joint filler after 24 hours of full curing, then apply primer and top coat as per design requirements

Q: Can high-density cement pressure boards be installed in outdoor areas with frequent temperature changes?

A: Yes, as long as expansion joints of 3-5mm are reserved between adjacent panels, qualified high-density cement pressure boards can withstand temperature differences from -30℃ to 80℃ without deformation.

Q: Do I need to do extra waterproof treatment for high-density cement pressure boards used in bathroom walls?

A: For shower area walls, applying 1 layer of waterproof coating on the board surface before tiling can extend the service life for 20% or more, which is a recommended practice.

Core Application Scenarios of High-Density Cement Pressure Boards in 2026

Jiete’s project records in 2025 and 2026 show the material is adopted across 4 fast-growing market segments, with proven performance in each use case.

Q: Can high-density cement pressure boards be used as floor underlayment?

A: Yes, 18mm and above thickness high-density cement pressure boards have enough load bearing capacity to be used as direct underlayment for laminate flooring, engineered wood flooring and luxury vinyl tiles.

Q: What are the limitations of high-density cement pressure boards?

A: Compared with gypsum boards, high-density cement pressure boards are 2-3 times heavier, so the keel base must be designed to carry extra load before installation to avoid safety hazards.
