Fire Performance You Can Rely On

Rated Euroclass A1, Gyproc MultiBoard offers dependable fire resistance in high-risk zones. It supports fire-rated enclosures, steel encasements, and drylining in sensitive environments. The 12.5mm board contributes to passive fire protection with minimal build-up height.
You can install this board in commercial or domestic properties where fire safety is essential. It’s a strong choice for wall linings, partitions, and ceilings in stairwells, plant rooms, or communal areas.

Tough Surface, Clean Finish

Gyproc MultiBoard is reinforced with glass fibres. This boosts impact resistance in high-traffic areas. The paperless finish creates a smoother surface, saving you time on skimming. It accepts paint, tiles, or wallpaper directly.

Handles Humid and Tough Spaces

MultiBoard performs in moisture-prone areas like bathrooms and soffits. It resists decay and holds its shape even with changes in humidity. You can use it in semi-exposed locations where standard plasterboard would fail.

Flexible Installation, Quick Setup

The board curves down to a 2.7m radius and cuts cleanly with standard tools. That makes it suitable for curved installations, custom ducting, and detail work. Lightweight and simple to fix, it suits quick builds and refurbishments.

Multi-Performance Plasterboard for Complex Builds

You can rely on British Gypsum Gyproc MultiBoard for fire, moisture, and impact resistance all in one. Whether you’re lining ducting, boxing in steels, or fitting soffits, this board handles it all.
