Frequently bought together
With a generous 90 mm drop, the GC Series is the deep-profile option in Decovision's LED coving range — cornice moulding with real presence for rooms that can carry it. Like all our coving it is cut from XPS (extruded polystyrene): a rigid, closed-cell foam with a smooth face that paints beautifully, at around a tenth of the weight of plaster. Made in the UK by Decovision.
Indirect lighting, hidden hardware
The GC profile conceals an LED channel along its upper edge. Run a strip inside it and the ceiling above glows with soft, even light while the strip itself stays completely hidden. It is the simplest route to the "floating ceiling" look — no plasterboard box-work, no electrician-built pelmet. LED strip not included, so you can match the colour temperature to the room.
Why weight matters
A deep plaster cornice of this size is a two-person lift and a genuine load on old lath ceilings. The GC in XPS (extruded polystyrene) is light enough to position one-handed, puts effectively no weight on the structure, and flexes with seasonal building movement instead of cracking along the joint line.
Sizes and packs
- Three profile widths: GC-A (90 x 155 mm), GC-B (90 x 190 mm), GC-C (90 x 290 mm)
- 2 m lengths, sold in packs from a single 2 m length to 30 m (16 lengths)
- Matching internal and external corners ready-made (20 cm)
- 20 cm sample available — ideal for testing profile scale, surface and paint before ordering a full room; samples are not for installation
Fitting notes
Use a solvent-free adhesive only and finish with water-based paint — solvent products damage polystyrene. No mechanical fixings are required. Most rooms are done in an afternoon: measure, cut with a fine saw, bond, fill the joints, paint.
Best rooms for a deep profile
High-ceilinged living rooms, dining rooms and master bedrooms take the GC naturally. Because XPS (extruded polystyrene) is closed-cell and moisture-resistant, it is equally at home above kitchen units or in a bathroom.
Why Decovision
Genuine XPS (extruded polystyrene) rather than soft bead foam, factory-made corners that save the hardest cuts, UK production, and an inexpensive sample so you can see the profile on your own ceiling line first. Start with a sample — the full packs will still be here tomorrow.
