British Gypsum Plasterboard: The Gold Standard for Drylining in UK Homes and Builds
Posted on October 09, 2025 by Insulation Warehouse Direct Team
When it comes to creating smooth, durable, and compliant internal walls and ceilings, few names carry the weight that British Gypsum does in the UK construction scene. As the UK's leading manufacturer of plasterboard under the Gyproc brand, British Gypsum has been setting benchmarks for over a century with innovative, high-performance products that blend reliability, sustainability, and ease of use. At Insulation Warehouse Direct, we've supplied countless rolls of insulation alongside these essential drylining boards, and we're big fans of how they complement our thermal solutions for energy-efficient builds.
In this blog, we'll dive into the world of British Gypsum plasterboard – spotlighting key products, their specs, real-world perks, and why they're a must-have for DIYers, renovators, and trade pros alike. Whether you're partitioning a new extension or lining a loft conversion, these boards make the job straightforward and future-proof.
What Makes British Gypsum Plasterboard Stand Out?
British Gypsum's Gyproc range is engineered for versatility, covering everything from standard drylining to specialised fire, acoustic, and thermal applications. At its core, each board features an aerated gypsum plaster core sandwiched between strong paper liners, delivering a lightweight yet robust finish that's ready for skimming, direct decoration, or jointing with their Thistle plasters.
What sets them apart? A commitment to innovation and sustainability. They're the first UK manufacturer to produce plasterboard from 100% recycled gypsum, slashing embodied carbon and aligning with net-zero goals. Plus, every product is rigorously tested to BS EN standards, backed by the iconic White Book – your go-to spec guide since 1972 – and covered by the lifetime SpecSure® warranty when used in approved systems.

Performance That Delivers: Real-World Insights
In our warehouse chats with customers and on-site feedback, British Gypsum boards shine for their hassle-free install and long-term payoff. Take Gyproc WallBoard: At just 7.5kg/m², it's a doddle to lift and fix to timber or metal studs, then skim with Thistle MultiFinish for a pro-level surface in under 24 hours. We've seen it transform draughty old walls into snug, EPC-boosting barriers when layered with our Celotex insulation.
For tougher gigs, FireLine MR holds up in steamy environments without warping, while SoundBloc F quiets noisy neighbours – one trade customer noted a 30% noise drop in a converted garage office. And with ThermaLine, you're ticking energy efficiency boxes without bulking up your build; its low-emissivity foil facing can enhance thermal performance by up to 10% in cavity systems.
Sustainability-wise, the recycled gypsum means less waste – over 1.2 billion tonnes diverted from landfills annually across Saint-Gobain. They're also zero-ODP and low-GWP, making them a smart pick for green certifications like BREEAM.
Of course, no product's perfect. Thicker boards like ThermaLine add cost and weight for full insulation needs, and always pair with proper fixings (e.g., Gyproc Drywall Screws) to avoid sagging. For external or high-rise use, check regs – most are limited to internal applications.
