The P1456D75VID semi-circular arch pediment is a structural-style decorative element designed to frame door headers, window tops, and interior passageways. Measuring 1150 mm in width, 671 mm in height, and projecting 170 mm from the wall, this architectural feature creates a classic portal effect. It introduces a curved transition to flat walls, transforming standard square openings into grand, classical entryways.
Engineered from a high-density rigid polymer with a rating of 150-200 kg/m³, this arch offers the physical toughness of wood without the vulnerability to moisture, rot, or wood-boring insects. Its closed-cell structure boasts a water absorption rate of under 1%, making it completely waterproof and dimensionally stable. Unlike heavy concrete or natural stone alternatives, its lightweight nature prevents structural strain on building facades while ensuring long-term durability.
Visually, the arch features a multi-tiered, stepped profile that curves symmetrically to meet a prominent, trapezoidal keystone at the center apex. This central block adds a focal point of classical architectural order. The smooth, pre-primed white surface is ready to receive paint, allowing the detailed shadow lines of the concentric curves to stand out sharply under both natural and artificial lighting.
This versatile component is widely implemented in premium European residential and commercial projects. It is ideal for exterior window pediments on classical facades, main entrance door surrounds, grand hotel lobby corridors, and interior wall niches. When paired with vertical pilasters or flat architrave mouldings, it forms a cohesive, high-end framing system for portals of various scales.
For installation, the dry and clean surface must be prepared before applying polyurethane (PU) assembly adhesive along the mounting edges. Mechanical fastening with screws is mandatory to secure the arch while the adhesive cures. Joint lines can be finished with a suitable exterior-grade filler and sanded smooth. While the factory-applied primer prepares the surface, applying an additional primer is optional and depends on your choice of paint manufacturer guidelines. Outdoor applications require a high-quality UV-resistant paint finish to prevent discoloration.
Combining the refined detail of traditional plasterwork with the modern resilience of advanced synthetics, this arch pediment is a low-maintenance, high-impact solution. It provides architects and interior designers with a reliable, easy-to-install decorative trim that stands up to harsh weather conditions and high-traffic interior environments alike.
- This semi-circular arch pediment is highly versatile, designed for both interior and exterior architectural embellishments
- On building facades, it serves as an excellent window header or main entrance door topper, especially when integrated into classical, neoclassical, or colonial-style villas
- For interior design, it is ideal for creating grand transitions in hotel lobbies, restaurant hallways, or residential corridors
- You can also use it to frame decorative wall niches, library alcoves, or mock fireplace surrounds
- To achieve a complete portal look, pair this arch with matching vertical pilasters or flat architrave mouldings
- When used outdoors, finishing the product with UV-resistant paint ensures it withstands harsh weather elements without yellowing or degrading
- Ensure the mounting surface is clean, dry, and free of dust
- Position the arch pediment and mark the alignment
- Apply a generous bead of polyurethane (PU) assembly adhesive along the rear mounting edges of the arch
- Press the profile firmly against the wall and secure it mechanically using screws through the pre-designated points; mechanical fastening is mandatory for safety and alignment
- Fill any screw holes and joint gaps with a high-grade acrylic joint filler
- Once dry, sand the filled areas smooth using 180-220 grit sandpaper
- The product comes with a factory-applied primer; however, applying an additional primer coat is optional and depends on your paint manufacturer's recommendation
- Finish with two coats of high-quality paint (UV-resistant paint is mandatory for all outdoor installations)
- This low-maintenance architectural element requires minimal upkeep
- For interior installations, occasionally dust with a dry microfiber cloth or wipe down with a damp sponge using mild soap
- For exterior installations, avoid using high-pressure water washers or harsh abrasive chemicals, as these can damage the paint layer
- We recommend checking the paint finish once a year on exterior facades to ensure the protective UV-resistant coating remains intact, especially on south-facing walls exposed to intense sunlight
