Strong Protection for Demanding Environments

Designed for spaces that face both moisture and daily wear, this Knauf Performance Plus board is a reliable choice. The moisture-resistant properties allow for use in kitchens, bathrooms, and utility areas, while the reinforced core adds strength and durability for lasting performance in commercial builds.
Its tapered edges make it easy to joint and finish with standard plasterboard accessories. Whether for single-layer walls or part of a multi-board system, it supports streamlined installation across walls, ceilings, and partitions.

Enhanced Acoustic and Fire Safety

With added density and glass fibre reinforcement, Knauf Performance Plus achieves sound insulation and up to 60 minutes of fire resistance when installed correctly. This makes it ideal for schools, hospitals, offices, and homes where safety and noise control matter most.

Compliance and Versatility in Design

Classified under EN 520 types A, D, F, H1, I, and R, this plasterboard meets multiple building code requirements in one product. Suitable for steel or timber stud systems, it works well across refurbishments and new builds alike. Installers and specifiers trust it for its reliability and multi-use flexibility.

A Practical Solution for Interior Builds

The 2400x1200mm format allows for wide coverage and reduces joint lines. Its consistent finish and ease of use make it a favourite among contractors aiming for both speed and quality. Pair it with moisture-resistant joint compounds for long-lasting results in wet-prone areas.

Choose Knauf for Peace of Mind

Knauf Performance Plus Moisture Resistant Plasterboard is backed by decades of performance and trust. From domestic builds to public projects, it delivers reliable protection, ease of handling, and code compliance in one sheet.

Great Customer Relations

Due to a mistake in communication ( mostly my mistake) the first delivery of bulk aggregate went to an address I used to live at. After asking to have a replacement delivery to the correct address Armstrong Cheshire re-scheduled the delivery within 3 days and with fantastic customer relations. I cannot recommend this company enough.
