Plasterboard
Ever wondered what gives modern homes their smooth, consistent walls and ceilings? Chances are, it's plasterboard!
Often overlooked, this versatile building material plays a crucial role in construction, offering much more than just a surface to paint on.
At Skim 2 Fin, we understand the importance of quality materials in achieving a perfect finish. Let's delve into why plasterboard is so vital, how to work with it, and the many benefits it brings to your building project.
Why Plasterboard is so important
Plasterboard, also known as drywall or gypsum board, is a panel made of gypsum plaster pressed between two thick sheets of paper. It's the go-to material for creating internal walls, ceilings, and even some partitions in residential and commercial buildings. Its importance stems from several key factors:
-
Speed and Efficiency: Compared to traditional wet plastering methods, installing plasterboard is significantly faster, reducing construction time and labour costs.
-
Smooth, Consistent Finish: It provides a uniform, flat surface that's ideal for painting, wallpapering, or other decorative finishes.
-
Fire Resistance: Gypsum itself contains water, which, when exposed to heat, helps to slow down the spread of fire.
-
Sound Insulation: Different types of plasterboard offer varying levels of soundproofing, helping to create quieter, more comfortable spaces.
-
Thermal Insulation: It contributes to the thermal efficiency of a building, helping to regulate indoor temperatures.
Tailored for Every Need
Not all plasterboards are created equal! Manufacturers have developed various types to meet specific performance requirements:
Standard Wallboard
The most common type, suitable for general-purpose wall and ceiling applications where no special performance is required.
Moisture-Resistant Plasterboard
Identified by its green paper facing, this board contains additives to reduce moisture absorption, making it ideal for bathrooms, kitchens, and other areas with higher humidity.
Fire-Resistant Plasterboard
Often identified by a pink paper face, this board contains glass fibre and other additives that enhance its fire resistance, making it suitable for areas requiring enhanced fire protection, such as garages, stairwells, or commercial buildings.
Acoustic Plasterboard
Thicker and denser than standard board, or featuring special cores, these boards significantly improve sound insulation, perfect for bedrooms, home cinemas, or offices.
Insulated Plasterboard
Features a layer of insulation (e.g., rigid foam) bonded to one side, offering enhanced thermal performance in a single board.
Vapour Control Plasterboard
Incorporates a metallic foil membrane on one side to act as a vapour barrier, preventing moisture from passing through the wall or ceiling structure.
Perforated Plasterboard
Designed with patterned perforations for improved acoustic absorption in large spaces where sound control is critical.

Fixing Methods for Plasterboard
The method you choose to fix plasterboard depends on the substrate (the surface you're fixing to) and the desired finish.
Screw Fixing (Direct to Timber or Metal Studs):
-
This is the most common method for new builds or stud wall construction.
-
Method: Plasterboard screws are driven directly through the board and into timber or metal studs (vertical framing members).
-
Advantages: Strong, secure, provides a flat surface.
-
Considerations: Ensure screws are flush with or slightly below the surface, not breaking the paper face. Spacing is crucial for stability.
Adhesive Fixing / Dot & Dab (Direct to Masonry Walls):
-
Ideal for quickly lining uneven masonry walls (brick, block, concrete).
-
Method: "Dabs" of specialist drywall adhesive are applied to the back of the substrate. The board is then pressed firmly against the wall, adjusted for plumb and level.
-
Advantages: Fast, can accommodate minor wall irregularities.
-
Considerations: Requires a clean, stable masonry surface. Proper spacing and alignment of dabs are essential.
Nail Fixing (Less Common for New Work, Sometimes for Repairs):
-
While screws are preferred, plasterboard nails can be used, especially in older installations or for minor repairs.
-
Method: Special ring-shank plasterboard nails are hammered through the board into timber studs.
-
Advantages: Can be quicker for very small areas.
-
Considerations: Less secure than screws, more prone to "popping" if not done correctly. Nail heads must be precisely driven.
Mechanically Fixed to Battens:
-
Sometimes used for ceilings or to create an even surface over an uneven substrate.
-
Method: Timber battens are first securely fixed to the wall or ceiling, and then the plasterboard is screwed or nailed to these battens.
-
Advantages: Allows for levelling of uneven surfaces, can create a void for services or additional insulation.
-
Considerations: Adds depth to the wall/ceiling.
Specialised Fixings for Metal Furring Systems:
-
In larger commercial projects or where specific acoustic/fire ratings are needed, metal furring channels are often used.
-
Method: Plasterboard is typically screwed into these metal channels using self-tapping metal screws.
-
Advantages: Highly precise, allows for complex designs, often integrates with insulation and fire-stopping systems.
