Plasterboards with Mineral Wool Insulation

Introducing a versatile plasterboard system that incorporates mineral‑wool insulation directly within the panel. Combining the familiar ease of traditional plasterboard with the proven thermal and acoustic performance of mineral wool, this solution is ideal for new builds, retrofits, and refurbishment projects where fire safety, sound reduction and energy efficiency are paramount. t offers a single‑layer solution that simultaneously addresses thermal performance, acoustic comfort and fire safety—all within a familiar plasterboard format. By integrating mineral‑wool directly into the panel, you eliminate the need for separate insulation blankets, simplify on‑site work, and comply with UK Building Regulations for energy efficiency and fire protection.

Upgrade your next project with a board that blends practicality, safety and sustainability, delivering a comfortable, quiet and secure indoor environment in one streamlined product.

CHARACTERISTICS

• Effective Thermal Insulation – The mineral‑wool core delivers an R‑value of approximately 2.5 per 10 mm thickness, helping to keep interiors warm in winter and cool in summer while reducing heating‑and‑cooling costs.
• Excellent Acoustic Dampening – The fibrous structure of mineral wool absorbs sound, making it particularly suited to party walls, office partitions and multi‑unit dwellings.
• Robust Fire Rating – Mineral wool is inherently non‑combustible; when encased in a fire‑rated plaster facing the board typically achieves a Class A fire classification, meeting UK Building Regulations for fire safety.
• Moisture‑Resistant Facade – The outer plasterboard skin is treated to repel damp, whilst the closed‑cell wool core resists water absorption, reducing the risk of mould formation.
• Slim Profile – The board provides substantial insulation without sacrificing interior space, a valuable benefit for rooms with limited headroom.
• Eco‑Friendly – Mineral wool is made from natural rock or slag fibres and contains a high proportion of recycled content, supporting greener construction practices.

APPLICATION

• External Walls – Upgrading the thermal envelope of new homes or refurbishing period properties while retaining original façade dimensions.
• Internal Partitions – Providing both sound insulation and fire protection for residential flats, offices, schools and healthcare facilities.
• Ceiling Linings – Delivering a lightweight, fire‑safe solution for multi‑storey blocks and commercial premises.

Typical Fitting Methods

• Mechanical Fixing involves securing each plasterboard panel directly to the supporting framework (timber joists, metal studs, or a secondary furring channel) with screws or special fasteners. The method can be carried out with battens (additional wooden or metal strips fixed to the main structure) or without battens, attaching straight to the primary framing.
• The “dot & dab” method secures plasterboard panels to the substrate using a strong, quick‑setting adhesive (commonly a polymer‑based or cement‑based fixing paste). Small “dots” of paste are applied to the back of the board, and the board is pressed onto the wall or ceiling (“dab”). No mechanical fasteners are used, although a few supplementary screws are often added for extra security.
