Product Overview
Long-length plasterboard sheet, measuring 2700 × 1200mm with a 12.5mm square edge, for use in ceilings, partitions, and wall linings where reducing horizontal joints improves finish quality.
The square edge profile allows boards to butt cleanly together without a recess, making it suited to textured finishes, direct decoration, or traditional jointing and plaster skim methods.
Increased board length reduces or eliminates the need for horizontal joints in standard-height rooms, improving installation efficiency and delivering a cleaner, more uniform finish.
At 12.5mm thick, the board represents the industry standard, offering reliable strength and stability for partitions and linings while minimising flex and reducing the risk of surface cracking.
Features & Benefits
- Square edge profile: Creates a flush joint suited to skim plaster finishes.
- Ivory paper face: Provides a clean, neutral base for paint, wallpaper, or plaster.
- Lightweight gypsum core: Simplifies lifting, cutting, and fixing.
- Ideal for ceilings: Reduced weight makes overhead work less demanding.
- Made by Knauf Drywall: Backed by quality and compliance standards.
- Large 2700mm x 1200mm size: Covers more area per sheet, helping to cut down on joints, finishing time, and material waste.
- 12.5mm thickness: Standard for drylining - the basis for most stud and track, lining, and manufacturer specs.
Applications
- Tall partitions: Larger sheet reduces horizontal joints on high walls.
- Ceiling lining in high rooms: Longer boards cover extended spans.
- Commercial fit-outs: Useful for spaces with above-standard ceiling height.
- Smooth finishes: Fewer board joints mean less jointing work.
Installation Guidance
- Fix with staggered joints: Improves strength and reduces cracking.
- Cut by scoring and snapping: Ensures accurate sizing.
- Store flat in a dry space: Prevents moisture damage and warping.
Compliance & Performance
- Manufactured in accordance with ISO 14001: Meets environmental standards.
- Manufactured to EN 520: Conforms to plasterboard requirements.
- In full compliance with ISO 9002 and BS1230: Part 1: 1985: Produced under recognised quality standards.
- Complies fully with BS EN520: Verified performance across applications.
- Fire Rating (Reaction to Fire): A2: Approved for internal linings.
