With the PVC Curb 90x120 cm, you choose flawless and completely watertight installation of your skylight or flat roof window. This PVC curb forms the essential, secure bridge between your roof covering and the window, and ensures natural drainage so that rainwater never remains on your flat roof. Where wooden structures can shrink, rot, or crack over time, this high-quality synthetic material provides a stable, maintenance-free base that permanently eliminates heat loss and thermal bridges. Whether you are a skilled DIYer or a professional installer, the well-designed system is created for fast, logical installation and can be seamlessly integrated with any type of roofing membrane.

The curb adapts effortlessly to your requirements and is suitable for both fixed glazing and opening systems for comfortable ventilation or smoke extraction. Tailor the design to your specific project: choose a sloped version to capture the maximum amount of daylight and distribute it evenly throughout the space, or opt for the straight version as the ultimate renovation solution. A durable, safe, and smart choice for any construction or renovation project.
