1st July 2026 Skirting and architrave profiles – decorative styles Decorative skirting boards run along the base of the wall and architraves frame doorways, both adding the visible profile detail that defines an interior’s character. Intrim’s decorative profiles range from softly stepped traditional forms to confident heritage references, each made to order in FJ pine, MDF, American Oak, and flexible polyurethane (for curved walls).. The profiles below represent the most popular decorative skirting boards in Intrim’s range, suited to projects from contemporary to heritage, French Provincial, and Modern Farmhouse. SK1006 – Warm, balanced profile crafted for Modern Farmhouse and contemporary French interiors SK767 – Elegant decorative skirting board profile suited to Hamptons and traditional Australian homes SK52 – Curved, sophisticated profile for Coastal Scandi, Modern Coastal, and contemporary interiors SK460 – Refined decorative profile that brings depth to federation and traditional rooms SK60 – Versatile decorative profile for timeless, classic interiors Skirting and architrave profiles – flush finish systems A flush finish system is a recessed skirting profile designed to sit flush with the wall, with no projection beyond the wall surface. They are the most architecturally distinctive products in the Intrim range, suited to contemporary, minimalist, and modern coastal interiors where the absence of decoration is itself the design choice. Intrim’s two flush finish systems each consist of a skirting profile that coordinates with a 2-in-1 door jamb and architrave, designed to be installed as a complete package. SK800 Shadowline + DJ800 – Intrim’s patented Shadowline skirting and accompanying door jamb system, recessed to finish flush with the wall Nova Vita SK810 + DJ810A/B – Intrim’s patented contoured flush finish skirting and coordinated door jamb system for a softer more refined interior Chair and dado rail mouldings Chair rails (also called dado rails in Australia) are horizontal timber moulding profiles installed across a wall, traditionally at about one-third of the wall height. In the Australian market, the two terms are used interchangeably to describe the same product. They can be used as a standalone decorative element or as a feature of a wainscoting moulding. The profiles below are the most-specified chair and dado rail options in Intrim’s range, with CR23C featuring a rebate designed specifically to sit on top of board-and-batten wainscoting with lining boards or VJ panelling. CR09 – Slim chair rail moulding suited to Modern Coastal and Farmhouse applications CR46 – Elegant chair rail profile for classic decorative wall detail CR62 – Decorative chair rail moulding suited to classic, heritage, and Parisian interiors CR84 – Classical chair rail profile that brings French Provincial and Parisian elegance to Australian interiors CR23C – Refined chair rail with a rebate designed for board and batten wainscoting, and clean lining board joins Inlay moulding profiles Inlay moulds are smaller-scale profiles used to define panels in wainscoting. Where a chair rail divides the wall horizontally, inlay moulds sit on the wall surface to create rectangular or square boxes that give wainscoting its character. The profiles below cover the most specified inlay options in Intrim’s range. IN32 – Versatile inlay profile suited to wainscoting and decorative wall panels in heritage, Farmhouse, and Hamptons homes IN09 – Classical inlay moulding for traditional, Hamptons, and French Provincial wall panel detailing IN16 – Decorative inlay mould that frames panels with refined French character IN106 – Geometric inlay profile suited to contemporary wainscoting, Art Deco and modern panel applications IN23 – Soft decorative inlay mould well-suited to French Provincial and traditional wainscoting Picture rail moulding profiles Picture rail mouldings are horizontal timber profiles installed near the top of a wall, originally designed to hang artwork without driving fixings into the plaster. They remain a strong heritage detail in Federation, Edwardian, and Victorian interiors. In contemporary spaces, the same moulding types are increasingly being used as horizontal feature lines. Intrim’s picture rail profiles range from traditional curved forms to streamlined contemporary designs. PR01 – Traditional picture rail moulding ideal for Victorian and heritage interiors PR20 – Decorative picture rail suited to classic Georgian heritage and Country Farmhouse-style homes PR27 – Versatile picture rail profile that adds horizontal detail to heritage and transitional interiors Sill nosing Sill nosing is the finished edge profile that runs along the top of an internal window sill, resolving the junction between the window frame and the wall surface. The sill nose itself is a single bullnose profile that, when paired with dado rails or inlay moulds, creates a defined, decorative finish. In Australian homes, the choice of sill nosing and complementary mouldings has a noticeable effect on how a window reads within a wall, particularly in heritage and contemporary interiors where the detail catches the eye. Intrim’s sill nosing profiles cover stylish options for residential and commercial applications. SN01 – Sill nosing designed to cap concrete or timber sub-sills with a clean finished edge SN02 – Sill nosing profile for window sill, threshold, or wall panelling applications SN03 – Sill nosing suited to traditional and contemporary window detailing Skirting block A skirting block (also called a plinth block) is a small upright moulding installed at the base of a door architrave where it meets the skirting. It resolves the junction between two profiles of different depths, removing the need for a complex mitre, and giving the detail a deliberate, finished appearance. Skirting blocks are most commonly specified in heritage, French Provincial, and Modern Farmhouse interiors. Intrim’s offers a range of different sizes and decorative treatments to suit most architectural styles. SB01 – Decorative skirting block (or plinth block) ideal for Hamptons, Farmhouse, and Victorian interiors SB03 – Skirting block designed to step between skirting and architrave with traditional and Hamptons-style detail SB04 – Stepped skirting block for traditional architrave terminations SB05 – Modern skirting block with a clean negative detail, designed to pair with the SQB01 corner block Crown moulding and cornice profiles Crown mouldings (also called cornices) are decorative timber profiles installed at the junction of the wall and ceiling. They add architectural definition to the upper edge of a room and, in heritage or Hamptons interiors, carry significant decorative weight. CM14 – Decorative cornice profile that adds character to coffered ceilings in Hamptons-style homes CM36 – Refined timber cornice suited to Hamptons, French Provincial, and traditional Australian interiors CM25 – Wide-profile cornice that establishes proportion and architectural presence at the ceiling line Lining board profiles Lining boards are wall and ceiling panelling boards installed in vertical or horizontal runs. They can be used to create board-and-batten wainscoting, full feature walls, or eye-catching ceiling decoration, particularly popular in coastal and country interiors. Several of Intrim’s most popular profiles feature a tongue-and-groove joint and a finished V-groove or shaped detail between each board for a seamless finish. LB100 / LB150 – VJ lining board with tongue-and-groove joins for indoor, alfresco, and wet area panelling LB43 – Intrim Cavetto Wall lining board featuring two fluted concave rows that push together into a continuous patterned wall LB35 – Lining board with a refined V-groove detail for contemporary panelling applications LB72 – Wider-format lining board ideal for Modern Coastal and Contemporary wall panelling Wall and ceiling batten profiles Wall and ceiling battens are linear timber moulding profiles installed at regular intervals across a wall or ceiling to create the rhythmic vertical or horizontal pattern that defines batten panelling. Where lining boards run edge-to-edge, battens are spaced apart, leaving the wall or ceiling surface visible between them. Intrim’s Casa Trim batten range includes the Cavetto WB43, a sister profile to the LB43 Cavetto lining board, that carries the same concave curve along its edge WB43 – Cavetto wall batten with a concave curve, designed to complement the LB43 Cavetto Lining Board for Art Deco interiors WB35 – Slim wall and ceiling batten for fine-grained batten panelling with the same detail as LB35 WB72 – Wider Casa Trim wall and ceiling batten for larger-scale coastal and contemporary designs with the same detail as LB72 WB44 – Wall and ceiling batten best suited to Modern Coastal Casa Trim batten applications Concave moulding profiles Concave mouldings are softly curved linear timber profiles that catch light and shadow across their surfaces. They are most commonly specified as internal wall details or as a decorative profile added to built-in joinery. Intrim’s concave profiles are available in different sizes, allowing the detail to be scaled to suit the proportions of the surrounding interior. Here are our three most popular sizes. CC20 – Small concave moulding for fine joinery details and tight internal corners CC40 – Mid-scale concave moulding decorative wall detail with strong visual impact CC60 – Larger concave moulding for architectural feature applications and wider joinery transitions Half round moulding profiles Half round mouldings are timber profiles with a semi-circular face. They are most commonly used as a finishing detail along the edge of joinery, as a slim decorative bead within a panelling scheme, or as a continuous horizontal line across a wall. The Intrim HR-series covers multiple size options, scaling from a fine bead detail to a more pronounced architectural feature. Our three most popular profiles are: HR20 – Small half round moulding for fine bead detail in joinery and panelling schemes HR40 – Half round moulding for sculptural joinery, panelling beads, and decorative wall lines HR60 – Larger half round moulding for prominent decorative beads and architectural feature lines Corner block profiles Corner blocks are small decorative blocks fitted at the top corners of a door or all 4 corners of a window, allowing the vertical and horizontal sections of the architrave to meet without a mitre. They are most commonly used for heritage restoration and bespoke applications. SQB01 – Squareline architrave corner block with a negative detail designed to match the SB05 skirting block PB (Pyramid) – Pyramid corner block crafted in MDF, used to eliminate angled architrave joins with a custom detail (works with 18mm architraves) CB (Rosette) – Rosette corner block made from MDF, a traditional way to finish the top corner of a door architrave Intrim sample boxes and design consultations Once you’ve identified a shortlist of timber moulding profiles, the next step is to compare them in person.
