Non-combustible Board

A1 non-combustible boards are also known as non-combustible cement boards and backer boards. They have an A1 fire safety rating, indicating the panels meet the top classification under EN 13501-1.

Fire boards are composed of inorganic compounds, most commonly magnesium oxide, calcium silicate, and fibre-cement. Installing them greatly improves fire protection performance, as the panels will not ignite or spread flames.

What are non-combustible panels used for?

Non combustible fire boards are used in:

• External sheathing and rainscreen support – A1-rated boards form a stable backing for façade systems.
• Internal partitions and ceilings – For buildings that require high fire-rating compliance.
• Service areas and plant rooms – Where a non-combustible cement board provides both fire and moisture protection.
• Render carrier and tile backer substrates – Supporting finishes in dry and wet environments.

Types of non combustible boards

Specialist non-combustible boards come in several material types. Two brands notable for their noncombustible panels are Euroform and Magply. Their fire boards fall into these main categories:

• Fibre-cement A1 non-combustible board – An example is the Easyboard, which is intended for exterior sheathing and tile backing.
• Magnesium oxide or magnesium-sulfate board – In addition to fire resistance, magnesium-based boards also provide substantial resistance to humidity. The Magply A1 Euroclass, a magnesium oxide-based panel, offers a thermal conductivity of 0.19 W/m·K.
• Render carrier cement bonded board – The non combustible cement board is mostly used as backing for renders or cladding systems. They are typically A1-rated or Class 0 (BS 476 Parts 6 & 7), depending on thickness and specification.
• Non combustible backer board for tiling – Specially designed for wet areas behind tiles. They retain dimensional stability under moisture and fire exposure. Best for kitchens, bathrooms, and wet zones.
