Single-Ply Membranes
Our single-ply membranes offer superior waterproofing for flat, curved, and sloped roofs. Designed to be bitumen-free and solvent-free, they provide UV stability, root resistance, and fire-retardant properties. Ideal for green, brown, or blue roof systems, these membranes ensure long-term durability and compliance with environmental standards.
Aluminium Profiles
High-quality aluminium profiles for roof edging, capping, and flashing ensure structural integrity and weather resistance. Available in multiple configurations, they integrate seamlessly with our membranes, offering adjustability and durability for new builds and refurbishments.
Daylight Systems
Daylight systems enhance natural light in buildings while maintaining thermal insulation. Our solutions include double-shell and multi-shell rooflights, designed for energy efficiency and aesthetic appeal without compromising waterproofing performance.

Our roof drainage systems address water management challenges for low-sloped roofs. Products include horizontal and vertical rainwater outlets, emergency outlets, and terrace grates, ensuring efficient water removal and preventing structural damage.
