Frequently asked questions about the Hard drywall category
What is Hard drywall and what is it used for?
Hard drywall is a gypsum-core board with a dense, reinforced surface designed for constructing durable walls, partitions and floor coverings. It’s used where increased mechanical strength is required, for example in floors, reinforced structures and high-wear areas.
What standard sizes of Hard drywall are in the catalogue?
The catalogue includes sizes shown in product names: 12.5×1200×3000 mm, 12.5×1200×2600 mm and KNAUF 900×2000×12.5 mm; plus reinforced KNAUF KEK13 sheets in 2.6×1.2 m and 3.0×1.2 m formats.
How do reinforced KNAUF KEK13 boards differ from BLUE HRAK boards?
KNAUF KEK13 reinforced boards offer higher strength and come in 2.6×1.2 m and 3.0×1.2 m sizes, suitable for load-bearing or heavily loaded structures. BLUE HRAK typically comes in 12.5×1200×2600 mm and 12.5×1200×3000 mm formats and is used where a hard surface is needed without extra reinforcement.
Is there a floor-specific board in the catalogue?
Yes, the catalogue includes a floor board KNAUF 900×2000×12.5 (PÕRANDA), designed for installation on floor structures and to bear typical floor loads. Use the floor board for leveling and strengthening screeds.
Can Hard drywall be cut with a standard drywall knife?
Yes, hard drywall can be cut with a drywall knife or a jigsaw, but the denser surface requires more effort and a sturdier blade. For large sheets, support the board at the edge and use a guide to achieve a straight cut.
What load-bearing capacity do reinforced KNAUF KEK13 boards have?
KNAUF KEK13 reinforced boards are designed for higher mechanical loads and suit structures requiring extra strength; exact load capacity depends on fixing method and supporting construction. Refer to the manufacturer's installation guidance and structural calculations for precise values.
Can Hard drywall be used in high-humidity rooms?
Standard hard drywall is not intended for continuous high-humidity exposure; for wet rooms you should choose moisture-resistant products. If only intermittent moisture occurs, check the moisture resistance of the specific model.
What board thicknesses are available and how does thickness affect stiffness?
The catalogue lists 12.5 mm thickness for BLUE HRAK and KNAUF 900×2000×12.5 sheets; 12.5 mm gives adequate stiffness when properly fixed, while reinforced KEK13 models provide extra strength due to construction and larger formats.
What fixing pitch is recommended for 1200×3000 mm and 1200×2600 mm boards?
For 1200×3000 mm and 1200×2600 mm boards a screw spacing of about 200–250 mm along edges and intermediate supports is recommended, though exact spacing depends on the frame and project requirements. Follow the manufacturer’s instructions and structural calculations.
What is the board surface like — do they need filler before finishing?
Hard drywall has a dense surface, but joints and any imperfections typically require joint compound and reinforcing tape. After filling and sanding the surface is ready for paint or wallpaper.
Which sheet should I choose for reinforced partitions in a commercial space?
Choose KNAUF KEK13 2.6×1.2 m or 3.0×1.2 m reinforced boards as they are designed for higher mechanical loads and larger coverage. Also consider fixing pattern and additional profiles to ensure rigidity.
What is Hard drywall and what is it used for?
Hard drywall is a dense plasterboard, typically 12.5 mm thick, designed for walls, partitions and floors to provide increased stiffness and impact resistance compared to standard drywall.
Which reinforced board models are available and how do they differ?
Available reinforced models are KNAUF KEK13 in 2.6x1.2 m and 3.0x1.2 m; these offer higher load-bearing capacity and stiffness than the BLUE HRAK boards (12.5x1200x2600 and 12.5x1200x3000), which are standard hard plasterboards.
Is there a floor-specific board in the catalogue and which one is it?
Yes — the catalogue includes the floor board KNAUF 900x2000x12.5, designed for floor constructions and providing required stiffness when installed correctly.
What sizes do Blue HRAK boards come in and why choose the 3000 mm length?
Blue HRAK boards are available in 12.5x1200x2600 and 12.5x1200x3000; the 3000 mm length reduces joints on large walls and gives a smoother finish for vertical installations.
Is Hard drywall suitable for internal partitions and which models are recommended?
Yes — hard drywall is suitable for partitions. Choose KNAUF KEK13 (2.6x1.2 or 3.0x1.2) for higher strength, and BLUE HRAK 12.5x1200x2600/3000 for standard partition use.
Can the KNAUF KEK13 3.0x1.2 m board be cut down in length and how easy is it?
Yes — the KNAUF KEK13 3.0x1.2 m board can be cut down. Use a jigsaw or circular saw with an appropriate blade for a clean edge and to prevent edge chipping.
How does the 12.5 mm thickness affect stiffness and what is it best for?
12.5 mm thickness provides good stiffness and impact resistance, making it suitable for walls, partitions and floors in high-use areas. Thinner boards are better for lighter, decorative structures.
Can you combine 2600 mm and 3000 mm boards on the same wall and how to joint them correctly?
Yes — combine 2600 mm and 3000 mm boards, but offset joints relative to the frame and fix to metal profiles. Use reinforcing tape and joint compound for a smooth finish.
What fasteners and fixing intervals are recommended for Hard drywall?
Use drywall screws with about 200 mm spacing at edges and 300 mm in the field. For KNAUF KEK13 reinforced boards follow the manufacturer's guidance on screw depth and spacing.
Is Hard drywall suitable as a substrate for wall tiling?
Yes — hard drywall is suitable for tiling in dry rooms. For wet areas, use dedicated moisture-resistant boards, which are not included in this category.
