termPIR® AL GK 50 mm PIR Board + Gypsum Plasterboard – Thermal Insulation and Interior Finishing

The termPIR® AL GK 50 mm insulation board is a modern solution combining the high thermal insulation performance of PIR with a factory-bonded gypsum plasterboard. The product is primarily designed for thermal insulation from the inside of buildings, combining an insulation layer with a surface ready for further finishing work.

The rigid PIR (polyisocyanurate) foam core provides very good thermal insulation performance with a relatively thin layer of material. This makes termPIR® AL GK boards particularly practical wherever it is important to reduce heat loss without significantly reducing usable interior space.

termPIR® AL GK 50 mm – high thermal insulation performance and convenient interior finishing

The termPIR® AL GK 50 mm insulation board combines the high thermal insulation performance of a PIR core with a factory-bonded 12.5 mm gypsum plasterboard. It is primarily intended for thermal insulation from the inside of buildings.

The rigid PIR (polyisocyanurate) foam core has a very low thermal conductivity of λD = 0.022 W/(m·K). The 50 mm PIR layer provides a high level of thermal insulation while keeping the overall system relatively slim.

By combining PIR with gypsum plasterboard, a single product provides thermal insulation while also creating a surface suitable for further interior finishing. This solution is particularly practical for renovation and thermal modernisation projects where reducing heat loss while preserving as much usable interior space as possible is important.

termPIR® AL GK 50 mm – PIR + gypsum plasterboard

The termPIR® AL GK 50 mm board features a rigid PIR foam core with a gas-tight multilayer facing based on paper and aluminium. A 12.5 mm gypsum plasterboard is factory-bonded to the thermal insulation layer.

This combination integrates thermal insulation and an interior finishing layer into a single product, which can simplify internal insulation work and reduce installation time.

Key parameters of termPIR® AL GK 50 mm

• PIR layer thickness: 50 mm,
• gypsum plasterboard: 12.5 mm,
• core: rigid PIR foam,
• PIR facing: gas-tight multilayer facing based on paper and aluminium,
• thermal conductivity λD: 0.022 W/(m·K),
• thermal resistance RD: 2.30 m²K/W,
• board dimensions: 1200 × 2600 mm,
• board area: 3.12 m²,
• edge finish: FIT – straight edge.

With a thermal resistance of RD = 2.30 m²K/W, the termPIR® AL GK 50 mm board provides effective protection against heat loss while maintaining a relatively slim construction. This is particularly important for internal insulation, where every additional centimetre of insulation can reduce the usable space of a room.

Applications of termPIR® AL GK 50 mm

termPIR® AL GK boards can be used for:

• internal wall insulation,
• insulation of pitched roofs and attics,
• under-rafter and between-rafter insulation systems,
• thermal renovation and modernisation of existing buildings.

The termPIR® AL GK 50 mm board is a practical solution wherever it is important to combine high thermal insulation performance with efficient preparation of the interior surface for further finishing. It can be used in both new construction and thermal upgrades of existing buildings.
