Plasterboard — How to Choose, Install and Where to Buy
This practical, trade-friendly guide explores plasterboard: its common types, standard sizes, and installation tips. It also explains why Chambers Timber is a good place to source boards and related drylining products.What is plasterboard?
Plasterboard, commonly called drywall, is a panel product. It features a gypsum core and paper facings. Builders use it to form internal walls, ceilings, and partitions. It is quick to fix and easy to finish. Furthermore, it is available in various specialist grades. These grades offer moisture resistance, acoustic performance, and fire protection.Common types and when to use them
Choosing the right board depends on location and performance needs. Typical types include:- Standard wallboard (9.5mm / 12.5mm) — Use this for most internal walls and ceilings. It suits areas where no special performance is required. Chambers Timber stocks standard Knauf wallboard in common panel sizes. This is useful for general drylining work.
- Moisture-resistant (MR) boards — These boards are ideal for kitchens, bathrooms, and utility rooms. They handle occasional moisture exposure effectively.
- Fire-rated boards — These higher-density boards provide fire protection. Install them where building codes require fire resistance, often as part of a tested partition or lining system.
- Acoustic / high-mass boards — These boards reduce sound. They are perfect for party walls or rooms needing enhanced privacy. Examples include tuned core acoustic boards. Chambers Timber lists acoustic plasterboard options, such as Knauf Soundshield Plus, for improved sound performance.
Standard sizes and thickness
Plasterboard sizes depend on manufacturer ranges and site needs. Common thicknesses include 9.5mm for walls and ceilings, 12.5mm for more robust wall and ceiling applications, and 15mm when increased strength or mass is necessary. Standard panel widths are typically 1200mm, with varying lengths like 1800mm and 2400mm. Choose lengths that minimise jointing and suit ceiling heights.When specifying thickness, consider the finish (skimming vs. jointing). Also, determine if extra mass is required for acoustic or fire performance.
Key accessories and finishing products
Buying boards is only part of the job. Jointing compounds, setting plasters, and fixings are equally important. Chambers Timber’s product range includes finishing plasters like Thistle and setting or patching compounds. They also offer screws and other fixings for drylining work. Look for fast-setting compounds when speed is essential. Use standard multi-finish plasters for smoothing.Fixings and installation tips
Follow good practice to ensure flat, durable walls:- Fix boards to joists or studs. Use the correct drywall screws and recommended centres (check manufacturer guidance).
- Stagger vertical joint lines between board rows. Avoid lining three board ends on the same stud.
- Use appropriate plasterboard adhesive for bonding applications where applicable. Always use proper jointing tape and compounds for long-lasting finishes.
- For moisture-prone areas, seal board edges. Use moisture-resistant finishes or tiles as required.
When to choose specialist boards
Certain jobs demand specialist boards. Use moisture-resistant boards in wet rooms. Install fire-rated boards where building regulations require them. Apply acoustic boards where party-wall performance is needed. Chambers Timber’s insulation and drylining category groups these specialist options. This helps tradespeople and DIYers find the right product quickly.Buying from Chambers Timber — what to expect

Checklist before you order
- Confirm the required board type (standard / moisture-resistant / fire / acoustic).
- Measure ceiling heights and wall lengths. This helps calculate panel quantities and minimize joints.
- Order adequate finishing compounds, tapes, and the correct drywall screws.
- Ask the merchant about lead times and delivery options for large orders.
