300 kg/m³ Calcium Silicate Board for Fire Door Core – Lightweight, Non-Asbestos Fire-Resistant Core Material

Qingdao Henry Calcium Silicate Board New Materials Co., Ltd. manufactures and supplies lightweight calcium silicate boards specifically developed for fire door core applications. With a nominal bulk density of 300 kg/m³, our calcium silicate core boards offer a combination of low weight, thermal insulation, dimensional stability and practical machining properties for fire door manufacturers.

We supply fire door manufacturers in Africa and support international customers in Europe, North America, the Middle East and other markets with standard and custom-cut calcium silicate core boards.

For fire door manufacturers looking for a reliable alternative to conventional heavy core materials, our 300 kg/m³ calcium silicate board provides a lightweight mineral-based solution that can be cut, drilled, routed and machined to suit different door constructions.

1. Calcium Silicate Board Supplied for African Fire Door Manufacturing

We have supplied our 300 kg/m³ calcium silicate board for use by a fire door manufacturing plant in Africa. The project requires precision-cut panels to fit specific fire door dimensions.

The supplied project dimensions include:

1. 2016 × 783 × 32 mm
2. 2016 × 769 × 34 mm

These custom dimensions are intended to accommodate the customer's fire door core requirements and manufacturing process.

In addition to project-specific cutting, we offer standard large-format calcium silicate boards measuring:

1. 1220 × 2440 × 38 mm

Customers can purchase standard boards for local processing or request custom-cut panels according to their production drawings and dimensional requirements.

2. Why Choose 300 kg/m³ Calcium Silicate Board for Fire Door Cores?

Fire door manufacturers need core materials that combine low weight, thermal insulation, dimensional stability and compatibility with industrial manufacturing processes.

Our 300 kg/m³ calcium silicate board offers several important characteristics:

Lightweight Construction

With a nominal density of 300 kg/m³ (18.7 lb/ft³), the board provides a lightweight mineral core solution. Its relatively low density can help reduce the overall weight of a fire door compared with heavier core materials, depending on the complete door construction.

Non-Asbestos Composition

The board is manufactured without asbestos, ceramic fibre or organic binder. Its mineral-based composition is suitable for applications where non-asbestos fire protection materials are required.

Thermal Insulation

Calcium silicate has low thermal conductivity, helping limit heat transfer through the core material. This property makes it suitable for consideration in fire door constructions and other thermal insulation applications.

Dimensional Stability

The board is designed to maintain its physical structure under elevated temperatures. Its linear thermal shrinkage is specified at less than 2% after exposure to 1000°C for 16 hours under the stated test conditions.

Easy Machining and Fabrication

Our calcium silicate core boards can be processed using ordinary carbide woodworking tools. Typical machining operations include:

1. Straight cutting and trimming
2. Drilling and boring
3. Routing and CNC machining
4. Glazing aperture preparation
5. Lock case and hinge pocket machining
6. Grooving and custom profiling

This makes the material suitable for fire door manufacturers requiring accurately machined core panels.

3. Technical Specifications – 300 kg/m³ Calcium Silicate Core Board

4. Thermal Conductivity

Low thermal conductivity is an important consideration when selecting core materials for fire door construction.

These typical thermal conductivity values are based on the product technical data sheet. Actual performance depends on test conditions and production variations.

5. Standard Sizes and Custom-Cut Fire Door Core Panels

Different fire door manufacturers use different door leaf dimensions, frame systems and core constructions. We therefore provide both standard-size boards and custom-cut calcium silicate core panels.

Standard Board Size

1. 1220 × 2440 × 38 mm

Custom Project Sizes

1. 2016 × 783 × 32 mm
2. 2016 × 769 × 34 mm

Other dimensions and thicknesses can be discussed according to customer drawings, production requirements and order quantities.

For bulk orders, we can coordinate cutting plans, packing arrangements and production schedules to meet the requirements of industrial fire door manufacturers.

6. Fire Door Core Material – Understanding Fire Resistance Ratings

Calcium silicate board can serve as a mineral core material in fire door assemblies. However, it is important to distinguish the fire-related properties of an individual board from the fire resistance classification of a complete fire door.

Fire resistance ratings such as EI30, EI60 and EI120 are assigned to complete door assemblies based on the applicable fire testing and classification requirements.

For European markets, relevant standards may include:

1. EN 1634-1: Fire resistance testing of door and shutter assemblies.
2. EN 13501-2: Fire resistance classification of construction products and building elements.

For the United States, relevant fire door testing and certification requirements may include UL 10C and NFPA 252, depending on the intended application and market requirements.

The final fire resistance performance depends on the complete door construction, including the core material, steel or timber facings, frame, hinges, locks, seals, glazing and installation details.

Our company supplies the calcium silicate core material and its technical data. The fire resistance rating of the finished door must be established through testing and classification of the complete door assembly by an appropriate testing body.

7. Applications

Our 300 kg/m³ calcium silicate board is suitable for consideration in the following applications:

1. Fire door core and infill materials
2. Fire-rated door leaf manufacturing
3. Fire-resistant partition systems
4. Fire-rated shaft wall infill
5. Fire-resistant wall and ceiling panels
6. Industrial thermal insulation
7. Backup insulation for furnaces and kilns
