FAQs

What are the main benefits of GTec Standard Plasterboard?

GTec Standard Plasterboard offers strength, durability, and versatility for a range of drylining applications. Its reinforced gypsum core resists cracking and impact damage, while the smooth face allows for painting, wallpapering, or tiling.

What’s the difference between the Square Edge and Tapered Edge boards?

The Square Edge board is ideal for straightforward installation where a flat joint isn’t required, while the Tapered Edge version allows for easy taping and jointing, creating a seamless finish that’s perfect for painting or decorating.

How should GTec Standard Plasterboard be stored and handled?

Store the boards flat in a dry, indoor environment away from moisture. Avoid stacking too high, protect the edges from damage, and handle with care to maintain the board’s integrity before installation.

Delivery

Every order is personally reviewed by our experienced team to ensure everything is correct before dispatch. We offer delivery from as little as the next working day on selected products, so please refer to the dark blue Estimated Delivery box above for the expected delivery timeframe for this item.

We work with trusted manufacturers and specialist delivery partners to ensure your order arrives safely and on time. You'll receive tracking details once your order has been dispatched, and if we need to confirm any delivery details, one of our team will contact you directly to keep everything running smoothly.

Roof Tiles & Fittings:

We recommend ordering an additional 10% of roof tiles to allow for any breakages that may occur during delivery or handling. Roof tiles are naturally fragile, and having a few extra on site helps prevent delays and ensures your roofing project can be completed without interruption.

If you're ordering multiple products from the same supplier, your order will be dispatched together once all items are ready. This means the longest lead time will apply.
