Poliüretan Arched Exterior Window Surround Trim

The KPEN30 structural window framing assembly is a comprehensive architectural solution designed to elevate standard window openings into stately visual landmarks. Specially engineered for high-end residential facades, luxury estates, and premium hospitality venues, this unified surround kit delivers a cohesive neoclassical aesthetic. It frames windows with a bold, three-dimensional profile that instantly enhances the building's exterior depth and curb appeal.

Manufactured from high-density rigid polymer (150-200 kg/m³), this grand frame kit possesses the structural feel and crispness of traditional stone or timber without the associated weight. Boasting a functional depth of 220 mm, a width of 2160 mm, and a height of 2660 mm, it is perfectly scaled for prominent windows. With negligible water absorption (under 1%) and high thermal stability ranging from -20°C to +80°C, the material resists rotting, cracking, and warping under extreme environmental exposure.

The design of the KPEN30 is characterized by its meticulously balanced proportions. It features a magnificent arched pediment accented by a central decorative keystone. This arch is supported by two ornate side corbels that transition seamlessly into smooth, stepped vertical jamb moldings, all anchored by a robust, projecting window sill. The deep-relief profiles create rich shadow lines that break up flat, monotonous facade surfaces.

Highly versatile in its application, this framing set is ideal for showcasing main facade windows, framing grand double-door entrances, or accentuating key architectural bays on hotels and restored historic landmarks. Indoors, it can be utilized in high-ceilinged ballrooms, luxury lobbies, or estate hallways to frame oversized mirrors, internal glass partitions, or decorative wall alcoves.

Installation is highly efficient compared to heavy precast concrete or plaster. The lightweight components are mounted using poliüretan (PU) montaj yapıştırıcısı and secured mechanically with corrosion-resistant screws. Seams and screw heads are finished with exterior-grade acrylic putty and sanded with 180-220 grit paper. The set comes pre-treated with a factory primer; however, applying an additional primer is optional and depends on your topcoat manufacturer's guidelines. A final finish of two coats of UV-resistant exterior paint is required to ensure long-term color stability.

In summary, the KPEN30 offers architects and builders a durable, low-maintenance alternative to plaster or wood. It provides a permanent, weather-resistant upgrade that ensures the property maintains its premium appearance and structural elegance for decades.
