Basic Definition & Core Properties of High Density Cement Pressure Board

High density cement pressure board refers to fiber reinforced non-asbestos cement board with density ≥1.5g/cm³, pressed under over 3000 ton industrial hydraulic machine. In practice, this production process eliminates internal air gaps completely, delivering far better mechanical strength than ordinary cement boards.

Q1: What raw materials are used for qualified high density cement pressure board?

Regular certified products use Portland cement, cellulose fiber, silica sand and non-toxic additives, no asbestos, no formaldehyde released, fully compliant with EU E1 environmental standard. 2026 third-party test data from SGS shows Jiete’s products have zero harmful substance emission.

Q2: What is the typical service life of high density cement pressure board?

From project cases across 37 countries since 2012, properly installed high density cement pressure board can work for over 50 years under normal exterior climate conditions, no cracking, no warping under -40℃ to 120℃ temperature range.

Industry consensus from 2026 Global Sustainable Construction Summit points out that high density cement pressure board reduces total building life cycle maintenance cost by 42% compared with traditional gypsum or wooden cladding.

Step-by-Step Correct Installation Workflow

Following standardized installation steps can maximize the performance of high density cement pressure board, and avoid 90% of common post-installation problems such as edge cracking or seam leakage.

1. Pre-treat the base wall: make sure the flatness error of base layer is less than 3mm per 2m, remove all floating dust and loose residues
2. Drill pre-buried holes 15mm away from board edges, avoid direct nailing to board corners to prevent chipping
3. Fix boards with special corrosion-resistant self-tapping screws, keep 2mm expansion gap between adjacent boards
4. Fill gaps with weatherproof sealant, then sand and polish the surface for subsequent finishing treatment

Performance Comparison With Other Common Building Boards

Actual test shows high density cement pressure board has obvious comprehensive advantages over most competing building materials for heavy load or high protection requirements scenarios.

Q3: Can high density cement pressure board be used for floor load bearing layer?

With 20mm or above thickness, high density cement pressure board can directly serve as the load bearing base layer for mezzanine floors, no additional cement pouring needed, which cuts 30% of on-site construction time for prefab projects.

Q4: Is high density cement pressure board suitable for bathroom wet zones?

With additional waterproof coating treatment on the surface, high density cement pressure board can be directly used as backing board for bathroom and kitchen walls, no deformation after long term contact with water vapor.

Key Application Scenarios in 2026 Construction Projects

According to 2026 global construction material consumption statistics, high density cement pressure board has become the top choice for 68% of public infrastructure projects that require high fire protection level.

Exterior Wall Cladding System

In practice, hundreds of high-rise residential projects in Southeast Asia and Middle East have adopted Jiete high density cement pressure board as exterior cladding base, it effectively resists heavy rain erosion and sand storm impact, no need for frequent repainting.

Fireproof Partition Wall For Commercial Buildings

For shopping malls, hospitals and industrial plants, 12mm thick high density cement pressure board partition can reach 3-hour fire separation requirement, fully meeting local construction code regulations in most regions.
