The Slimline Square Set Cornice

Introducing the Slimline Square Set Cornice

Clean lines. Sharp detail. Modern simplicity.

The Slim Line is the square-set look at its most understated a slim, solid profile that sits tight to the ceiling for a crisp, minimal shadow line effect without any bulk. Where you want the clean architectural edge but not a prominent cornice, the Slim Line delivers it, and it fits fast with none of the drying time or mess of traditional square-setting. A sharp finish for trade to turn around quickly, and an achievable modern detail for renovators.

It's also a smart, low-profile fix for cracked square-set corners. Because it's XPS foam fixed with a flexible adhesive, it moves with the building where rigid plaster cracks at the join so it covers a failed corner cleanly and stays sound (with significant movement you may see slight cracking in the paint along the joint, but the profile itself won't crack like plaster). An easy, cost-effective way for trade to make damaged square-set disappear on new work or callbacks.
