Product Overview
XPS Laminate Plus Insulated Plasterboard measuring 27mm thick and 2400mm x 1200mm in size. A composite drylining board combining 9.5mm wallboard with an extruded polystyrene (XPS) insulation core for enhanced thermal and moisture performance.
The rigid XPS layer offers higher compressive strength and lower water absorption than standard EPS, providing reliable thermal insulation in areas exposed to intermittent damp or condensation risk.
Designed for direct application to masonry or solid wall surfaces, the laminate improves internal comfort, reduces cold bridging, and supports compliance with modern energy standards.
The plasterboard face provides a smooth, flat surface suitable for direct decoration or plaster skim finishing, making it an efficient solution for both refurbishment and upgrade projects.
At 27mm overall thickness, it is suited to drylining applications where improved insulation and moisture resistance are required within a compact wall build-up.
Features & Benefits
- Laminated XPS and plasterboard construction: Combines insulation and interior finish in one composite board.
- Extruded polystyrene insulation: Provides superior thermal resistance with minimal moisture absorption.
- Smooth plasterboard surface: Ready for direct painting, wallpapering, or skim plaster finish.
- Rigid and dimensionally stable: Maintains flatness and edge integrity during handling and installation.
- Lightweight composition: Simplifies transport and fixing, reducing installation time.
- Moisture-resistant insulation core: Suitable for use on walls prone to minor damp or condensation.
- Energy-efficient design: Improves wall U-values and supports compliance with energy performance requirements.
- 27mm thickness: Ideal for refurbishment work where insulation upgrade is required without significant space loss.
Applications
- Internal wall drylining: Upgrades thermal and moisture performance of external or solid walls.
- Refurbishment projects: Enhances comfort and reduces energy consumption in existing buildings.
- Ceiling or roof slopes: Provides a continuous thermal layer in room-in-roof conversions.
- Utility and service areas: Suitable for drylining semi-exposed or intermittently damp rooms.
Installation Guidance
- Fix with adhesive dabs or mechanical fixings: Ensures full bond and stability on masonry or stud walls.
- Cut cleanly with fine-tooth saw or knife: Allows precise fitting around sockets, reveals, and openings.
- Seal perimeters and joints: Maintains insulation continuity and air-tightness.
- Store flat and dry: Protects plasterboard face and prevents distortion prior to installation.
Compliance & Performance
- Manufactured to EN 13950: Conforms to European standard for laminated insulation boards.
- Thermal conductivity (XPS layer): Approx. 0.033 W/mK.
- Moisture absorption: Very low, maintaining insulation performance in humid environments.
- Environmental performance: XPS core is free from CFCs and HCFCs and offers recyclable content.
- Important note: Install in accordance with internal wall insulation guidance to achieve declared thermal values and moisture control.
