Intrim® SN03 Sill Nosing

Refined sill detailing for luxury traditional interiors

Complete your window detailing with Intrim SN03 Sill Nosing – a substantial profile designed to neatly cover and finish concrete or timber sub-sills while adding architectural refinement to the window surround.

Featuring a generous bullnose front edge and a substantial 30mm thickness, SN03 creates a more pronounced and luxurious sill detail than standard nosings. Its smooth curved profile softens the transition between the sill and surrounding wall, helping create a polished, professionally finished appearance.

Ideal for French Provincial, Georgian, Victorian, Hamptons, and other traditional interiors, SN03 complements decorative architraves, wall panelling, and heritage-inspired mouldings, contributing to a cohesive architectural aesthetic throughout the home.

Available in a wide range of widths, SN03 can be specified for everything from standard residential window sills to grand custom homes where generous proportions and quality detailing are essential.
