Plasterboards with Phenolic Insulation

Designed for new‑build and retrofit projects, Plasterboards with Phenolic Insulation combine the familiar ease of traditional plasterboard with the excellent thermal efficiency and fire‑resistance of phenolic insulation. It delivers a compact, fire‑safe, and energy‑efficient solution that meets UK Building Regulations for thermal performance and fire safety. By integrating phenolic insulation directly into the plasterboard, you reduce the number of separate building layers, simplify construction, and achieve a comfortable, sustainable indoor environment.

Upgrade your next project with plasterboard that combines the convenience of traditional drywall with the advanced benefits of phenolic insulation—comfort, safety and efficiency in one sleek, easy‑to‑install panel.

CHARACTERISTICS

• Superior Thermal Performance – Phenolic foam delivers a high R‑value per millimetre, meaning thinner boards can achieve the same heat‑loss reduction as much thicker conventional systems.
• Robust Fire Rating – The phenolic core is inherently fire‑retardant, typically achieving a Class A fire rating, enhancing safety without the need for additional fire‑protective layers.
• Slim Profile – At just 12 mm thickness the board provides substantial insulation while preserving interior space, ideal for rooms where floor‑to‑ceiling height is at a premium.
• Easy Installation – these boards can be fixed to timber or metal studs using conventional plasterboard screws. Or, by the "dot & dab" method. The phenolic core does not affect standard joint‑taping and finishing procedures.
• Environmentally Considerate – Modern phenolic foams employ low‑global‑warming‑potential blowing agents, and the gypsum layer incorporates recycled content, supporting greener building practices.

INSTALLATION

• External and internal walls in new homes.
• Refurbishment schemes where increasing thermal performance without losing headroom is essential.
• Commercial premises requiring both fire safety and energy efficiency.

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.
