Polyurethane Classical Window Surround and Pediment Set
Details
Matching polyurethane window casing and pediment components for KPEN29 surround set
Enhance your facade with matching polyurethane components for the KPEN29 window surround. Includes durable moldings (P1456, P1458, P1470), decorative corbels (P9927, P9950), and elegant pediments (P2833, P1470A) for seamless installation.














The KPEN29 architectural window surround set is a complete, high-profile framing solution designed to elevate exterior facades with classical grandeur. Measuring 257x2080x2330 mm, this grand assembly transforms plain window openings into commanding architectural focal points. It is engineered specifically for premium projects where historical depth and structural definition are required to make a lasting impression.
Crafted from high-density rigid polyurethane (150-200 kg/m³), this structural composite offers the realistic density and hardness of natural wood without any of its organic vulnerabilities. The closed-cell material structure guarantees water absorption of less than 1%, rendering the trim completely immune to rot, swelling, insects, and moisture damage. Tested to withstand temperature fluctuations from -20°C to +80°C, the frame maintains its dimensional stability without warping, shrinking, or cracking over decades of exposure.
The design of the KPEN29 showcases exquisite classical relief work. It is crowned by a sweeping arched pediment adorned with deeply carved baroque floral scrollwork. Below, the lintel is supported by two ornate side pilasters capped with detailed corbels. These corbels feature intricate classical mask motifs and acanthus leaf details that create a captivating three-dimensional play of light and shadow. The crisp, clean lines of the vertical moldings provide a perfect geometric balance to the ornate carvings above and below.
This decorative set is ideal for grand villa exteriors, boutique hotels, historical restorations, and upscale commercial facades. Beyond windows, it serves as an imposing frame for main entryways or decorative blind window arches. Its lightweight nature allows it to be mounted on modern lightweight wall systems, such as exterior thermal insulation composite systems (ETICS), without adding dangerous structural loads.
The components are delivered with a factory-applied matte primer coat that prepares the surface for final painting. While this base coat facilitates paint adhesion, an additional primer may be applied depending on your choice of paint manufacturer. For installation, the parts must be secured using a premium polyurethane (PU) assembly adhesive combined with mechanical screws for structural safety. The entire assembly must be finished with a high-quality, UV-resistant exterior paint to shield the material from solar degradation.
- This grand combined window surround set is designed primarily for exterior facade decoration, transforming standard windows into classical architectural features
- It is highly recommended for luxury private villas, estate homes, boutique hotels, and premium commercial buildings seeking a neo-classical or baroque aesthetic
- Additionally, the set can be adapted for interior use in expansive spaces such as hotel lobbies, grand ballrooms, or high-end restaurants to frame large mirrors, display alcoves, or interior windows
- For a cohesive exterior design, pair this set with matching rustication corner blocks, decorative brackets, and horizontal band moldings along the building's facade
- Ensure the installation surface is clean, dry, and structurally sound
- Pre-align the pediment, side pilasters, and bases to verify fitment
- Apply a generous amount of polyurethane (PU) assembly adhesive to the rear mounting surfaces of the profiles
- Press the components firmly onto the wall and secure them mechanically using stainless steel screws to ensure permanent stability
- Fill all joints and screw holes with a high-quality exterior-grade joint filler or polyurethane sealant
- Once dry, sand the filled areas smooth using 180-220 grit sandpaper
- Apply an optional exterior primer coat if recommended by your paint manufacturer, and finish with at least two coats of UV-resistant exterior paint
- The high-density material requires minimal maintenance once properly installed and painted
- To remove dust, dirt, or environmental soot, gently wash the surface with low-pressure water and a mild detergent
- Avoid using highly acidic, alkaline, or solvent-based chemical cleaners
- Inspect the joint sealants and paint coating annually to check for any physical damage or building settlement cracks
- If any damage occurs, simply patch the area with exterior-grade spackle, sand smooth, and re-apply the UV-resistant topcoat
