The P14D50D320VI is a high-performance architectural element designed to frame arched doorways, curved windows, and majestic passages. Measuring 110 mm in profile width, with a massive 3840 mm span and 1920 mm rise, this semi-circular framing trim provides a clean, continuous curved boundary that softens harsh rectangular lines in both residential and commercial structures. Its smooth, flat-curved face offers a minimalist yet impactful aesthetic, bridging the gap between classical geometry and modern architectural design.
Engineered from high-density rigid foam, this architectural trim boasts a density of 150-220 kg/m³ (production target ~160 kg/m³), delivering wood-like hardness and impact resistance while remaining remarkably lightweight. The closed-cell structure guarantees a water absorption rate of under one percent, making it completely immune to moisture, rot, swelling, and insect infestation. Capable of withstanding extreme temperature fluctuations from -100 °C / +80 °C without warping or expanding, it ensures exceptional dimensional stability over decades of service.
Visually, the P14D50D320VI features a beautifully stepped, multi-layered profile that transitions smoothly along its perfect semi-circular trajectory. The symmetrical ridges run parallel to the curve, creating subtle shadow lines that emphasize the scale and height of any opening. This elegant step-profile adds depth to plain walls, making it an ideal choice for projects where clean lines and geometric precision are paramount.
Designed for versatile applications, this curved molding is highly suited for both indoor and outdoor environments. In exterior facades, it serves as a grand window pediment, entrance frame, or porch archway enhancement. Indoors, it can be utilized to define transition passages between grand salons, hotel lobbies, and upscale dining areas. Because it is completely waterproof, it can also be safely installed in high-humidity zones like indoor pool halls or covered spa terraces.
Compared to heavy, fragile plaster or high-maintenance timber, this lightweight polymer alternative simplifies shipping and installation significantly. The mounting process involves preparing a clean, dry surface, applying a polyurethane (PU) assembly adhesive, and securing the arch with mechanical screws for permanent stability. The factory-applied primer coat prepares the surface for final painting; however, applying a compatible professional primer before painting is optional and subject to the installer's preference. For outdoor installations, finishing with a high-quality UV-resistant paint is mandatory to prevent surface yellowing.
- This grand semi-circular arch molding is highly versatile, acting primarily as a decorative window header, doorway frame, or transition archway
- On exterior facades, use it to crown large windows or main entryways in Mediterranean, neoclassical, or modern villa designs, immediately boosting curb appeal
- Inside, it excels in creating open-concept transitions between living rooms and hallways, or framing alcoves in luxurious hotel lobbies and fine dining restaurants
- For a cohesive look, pair it with vertical pilasters or straight pediment moldings to build a complete, majestic entryway system
- Begin by ensuring the mounting wall or frame surface is clean, dry, and free of dust
- Measure and align the arch trim precisely against the opening
- Apply a high-quality polyurethane (PU) assembly adhesive generously to the back of the profile
- Position the trim and secure it mechanically using screws to ensure absolute stability during the adhesive's curing process
- Fill any screw holes and joint lines with a suitable exterior-grade acrylic filler, then sand smooth with 180-220 grit sandpaper
- The factory primer prepares the surface, but applying an additional primer coat remains optional
- Finish with two coats of water-based or synthetic paint
- For exterior setups, UV-resistant paint is mandatory
- Maintenance is minimal and straightforward
- The smooth surface can be cleaned easily using a damp cloth, sponge, or soft brush with mild soap and water
- It is highly resistant to moisture, allowing for periodic high-pressure washing on exterior facades if necessary
- Avoid using harsh abrasive cleaners, solvents, or strong chemical strippers that could damage the paint layer
- For outdoor installations, we recommend inspecting the paint finish every few years and applying a fresh topcoat if signs of weathering or UV fade appear
What are the dimensions of P14D50D320VI?
P14D50D320VI measures 110 × 3840 × 1920 mm (width × length × height), diameter 3840 mm.
How is P14D50D320VI installed?
Begin by ensuring the mounting wall or frame surface is clean, dry, and free of dust. Measure and align the arch trim precisely against the opening. Apply a high-quality polyurethane (PU) assembly adhesive generously to the back of the profile.
