VITCAS Fireplace Construction Board

High Temperature Insulation Board – VITCAS CS Fireplace Construction Board

VITCAS CS Fireplace Construction Board is a high-temperature, heat-resistant insulation board designed for constructing fireplace enclosures, false chimney breasts, tiled stoves and surrounds for inset and cassette stoves. Rated to 1000°C (1832°F), the CS board combines thermal insulation with mechanical strength, allowing suitable fireplace structures to be built without a separate supporting framework.

VITCAS CS Construction Boards are particularly useful for creating fireplaces where no existing chimney breast is present, including installations along walls and in room corners. Available in 1000 × 610 × 30 mm and 500 × 610 × 30 mm sizes, the boards can be used to construct and insulate custom fireplace enclosures.

Key Features

• High temperature resistance: VITCAS CS Fireplace Construction Board is rated to 1000°C (1832°F).
• Thermal insulation: Helps reduce heat transfer through fireplace enclosures and surrounding construction.
• A1 non-combustible: Reaction-to-fire classification in accordance with EN 13501-1.
• Mechanical strength: Suitable for forming self-supporting fireplace enclosures when installed as part of an appropriate construction system.
• Flexible construction: CS boards can be used to create customised fireplace shapes, including wall-mounted and corner configurations.
• Board dimensions: Available in 1000 × 610 × 30 mm and 500 × 610 × 30 mm.

Typical Applications

• Fireplace construction: Building new fireplace enclosures and surrounds where no existing chimney breast is available.
• False chimney breasts: Constructing insulated chimney breast enclosures for suitable heating appliance installations.
• Inset and cassette stoves: Building heat-resistant surrounds and enclosures around installed stove units.
• Tiled stoves: Constructing and insulating tiled stove enclosures and surrounds.
• Corner fireplaces: Creating custom fireplace structures in room corners or along existing walls.

Installation note: VITCAS CS Fireplace Construction Board must be installed using suitable fixing and jointing materials, with adequate support for the intended construction. The 1000°C rating applies to the board material and does not replace the appliance manufacturer's installation clearances or fire safety requirements.

Installation and Finishing of VITCAS CS Fireplace Construction Board

1. Cutting and shaping: VITCAS CS Fireplace Construction Boards can be cut, drilled and shaped using conventional woodworking tools to suit the required fireplace enclosure or false chimney breast configuration.
2. Fixing: Position and secure the CS boards using suitable screws and fixings, ensuring the completed fireplace construction is adequately supported and stable.
3. Edge preparation: Apply VITCAS BP Board Adhesive Primer / Hardener to the cut edges of the boards to strengthen the surface and prepare it for adhesive bonding.
4. Jointing and sealing: Bond and seal adjoining CS board edges using VITCAS Board Adhesive 1300°C. Apply the adhesive evenly to form secure joints between the fireplace construction boards.
5. Surface preparation: Apply VITCAS PVA Adhesive Sealer to the board surfaces in accordance with the finishing system instructions. Allow the primer to dry as specified before plastering.
6. Heat-resistant plastering: Apply VITCAS Heat Resistant Plaster as a finishing skim coat over the prepared fireplace construction boards, following the recommended application thickness and drying instructions.
7. Decorative finishing: Once the plaster has dried completely, finish with a suitable paint or decorative coating compatible with the expected surface temperature and fireplace installation.

Installation note: Follow the appliance manufacturer's clearance requirements and the instructions for all VITCAS adhesives, primers and finishing products. The 1000°C temperature rating of the CS board does not determine the permissible temperature of the complete installation.
