The Right WallBoard for Quality Builds
Finding a plasterboard that strikes the right balance between reliability, versatility, and trade pricing is crucial. As someone who values efficiency, durability, and affordability, you know that cutting corners on materials can quickly lead to longer build times and headaches down the line. That is why we at Insulation Warehouse Direct focus on offering materials that won’t let you down, including the dependable British Gypsum Gyproc WallBoard Square Edge 1800mm x 900mm x 12.5mm.
Why Gyproc WallBoard Stands Out
When you’re preparing for a refurbishment, an extension, or even a full-scale new build, the last thing you need is fuss with awkward materials. Our Gyproc WallBoard is specifically engineered for internal walls and ceilings. The square edge profile makes installation straightforward, which means you or your team spend less time prepping and more time finishing the job.
We’ve all had our fill of boards that crumble or chip with every cut, but Gyproc’s dense, gypsum-based core remains robust through handling and fixing. As an added benefit, it’s easy to cut, shape, and screw in, making it a go-to choice whether you’re tackling a simple room partition or a full office refit.
And because we know nobody wants limited options, you can either apply a skim of plaster for the perfect finish, or decorate it directly for a fast turnaround—ideal if you need rooms back in action quickly.
A quick note: this product performs best in dry environments. For bathrooms, kitchens, or anywhere with added moisture, consider using boards specifically rated for wet conditions.
Designed for the Demanding Tradesperson
Trade customers and professional installers form the backbone of many of our transactions, and we get what you need. Whether you’re a builder, renovation expert, or a homeowner handy with a screwdriver, our British Gypsum WallBoard was chosen because it consistently delivers.
Every sheet offers reliable strength and rigidity, meaning less waste and fewer callbacks. The board’s square edge format creates neat, clean joins—just the thing for joint taping or a seamless plaster finish. The standard 12.5mm thickness gives excellent stability and acoustic performance for residential and commercial settings alike.
We don’t just select any product for our range. We’ve built relationships with leading brands, and British Gypsum is a name we trust. This ensures you get consistency in supply, quality control, and manufacturer support every time you order with us.
Efficient Projects are Cost-Effective Projects
One of the core reasons our customers keep coming back is that we’ve built a business on competitive trade pricing. With direct access to the products professionals rely on, every pound spent with Insulation Warehouse Direct is invested in quality. That means no wasted time replacing damaged goods and no second-guessing the material’s performance inside your wall or ceiling.
Our clients—whether managing a housing development or renovating a single flat—consistently emphasise the importance of both cost and efficiency. With our Gyproc WallBoard, we help you keep budgets in check, while still achieving finishes to be proud of.
Installation Made Simple
If you value a clean job with minimal fuss, you’ll want to ensure every step, from delivery to install, is as smooth as possible:
-
Easy to handle: At 1800mm x 900mm, each board is big enough to cover space quickly but compact enough for one person to manoeuvre safely
-
Quick to fit: The board accepts drywall screws easily, ensuring strong, stable fixing every time
-
Customise as needed: Trim to size with a utility knife—no power tools required for standard cuts
-
Flexible finishing: Suitable for plastering or direct decoration, so you set your schedule
Sustainability Matters
We recognise the responsibilities of construction go beyond just cost and convenience. Many of our customers are concerned about both environmental and economic impacts. That’s why the British Gypsum Gyproc WallBoard we supply is produced with sustainability in mind, helping to reduce waste on your project. While this specific board is not water-resistant, it does support lower environmental impact compared to some composite alternatives—another thoughtful choice for eco-conscious contractors and homeowners.
