PU Insulated Panel
Outstanding insulation – energy saving – built to last.
Outstanding insulation – energy saving – built to last.
The PU (polyurethane) panel is an effective insulation solution built around a rigid, high-density PU core that blocks heat transfer, saves energy and keeps the internal environment stable. It is produced on modern lines, installs quickly and suits a wide range of projects.
Outstanding thermal insulation
Energy saving
Flame-spread resistance (optional)
Durable and corrosion-resistant
Fast to install – cost-efficient
The PU core has a low thermal conductivity, holding temperatures steady and cutting running costs.
Takes load off the cooling or heating system and cuts electricity use considerably.
Flame-retardant B1/B2 PU cores can be produced to project requirements.
A tongue-and-groove design that is light, quick to install and shortens the build schedule.
High-grade coated steel that resists rust and stands up to harsh environments.
A flat surface in a wide range of colors, easy to clean and maintain.

Factory walls, ceilings and roofs

Holds temperature and protects stored goods

For clean, sterile environments

Meets food hygiene and safety requirements

Partitions, ceilings and effective sound insulation

The PIR panel uses a polyisocyanurate core — an upgrade on PU with a more thermally stable closed-cell structure. It has the lowest thermal conductivity of any of our panels and better fire performance, which suits cold stores and cleanrooms.

The EPS panel uses an expanded polystyrene core, balancing insulation against cost. Light and quick to install, it is the economical choice for partitions, ceilings and factory cladding.

The glass wool panel uses a glass fibre core — lighter than rock wool but still non-combustible, a good sound absorber and environmentally friendly. It suits partitions, ceilings and anywhere needing acoustic treatment.

The rock wool panel uses a stone mineral wool core — all but non-combustible and a good sound absorber. The choice for fire compartmentation, fire-rated walls and heavy industrial buildings.
