Henkel Polybit Bituboard 1m X 2m X 3.5mm

Bituboard 3.5mm is non-biodegradable, weatherproof, warp-proof, and rot-proof. It offers excellent resistance to chemicals and improved puncture resistance, making it compatible with most waterproofing systems while ensuring long-lasting performance.

The technical specifications include a thickness of 3.5 mm, a density of 1.1-1.2 g/cc, and a mass per unit area of approximately 4.0 - 4.2 kg/m². It has a softening point greater than 105°C and demonstrates good hydrostatic pressure resistance without leakage at 5 bar for 50 meters.

Installation requires ensuring that the ambient temperature is between 5°C and 55°C. The boards can be fixed using double-sided adhesive tape, bonding agents, or torching on torch-applied membranes. It is crucial to support the boards until the adhesive sets properly.

Bituboard is primarily used as protection for waterproofing membranes during construction processes, absorbing impacts from aggregates and foot traffic while preventing damage from reinforced steel edges during backfilling.

Bituboard is designed to withstand various environmental factors due to its tough composition. It is resistant to chemicals, UV radiation, and extreme weather conditions, ensuring that it maintains its integrity over time.

Bituboard should be stored in a dry and shaded area away from direct sunlight and heat sources. It is recommended not to open the shrink wrap until ready for application to prevent moisture ingress and potential damage.

Bituboard does not contain harmful substances such as asbestos or chromated copper arsenate. It complies with safety standards for construction materials, making it a reliable choice for waterproofing applications.

Henkel Polybit Bituboard is a polymer-modified bitumen roofing board reinforced with fiberglass. It provides waterproofing, thermal insulation, and noise reduction, and is designed for roofing projects across residential, commercial, and industrial buildings. It can be used as a weatherproofing layer or roof underlayment on flat or low-slope roofs.

The board combines polymer-modified bitumen for waterproofing with a reinforced fiberglass net for strength and stability. It is UV resistant and weather-tough, lightweight and flexible for easy handling, and often features self-healing properties to help seal minor damages over time.

Polybit Bituboard typically offers higher tear strength, easier handling and installation, self-healing capabilities, and added insulation and noise reduction compared with traditional bitumen sheets, contributing to improved long-term performance.

Polybit Bituboard is available in a range of thicknesses and sheet sizes to fit different roof designs and climate conditions. To select the appropriate variant, consider roof span, expected loads, insulation needs, and local weather. Check the current product options on Fepy for exact availability.

Common applications include flat or low-slope roofs, commercial and industrial roofing projects, terraces and outdoor decks, and green roof systems. It can be used as a weatherproofing layer or as part of an overall roofing assembly to improve insulation and protection.

Installation generally involves preparing a clean, dry substrate, laying panels with appropriate overlaps, and securing them with mechanical fasteners or bonding adhesives as specified for the substrate. Joints are sealed with a compatible sealant, and once installed, the system is inspected for proper adhesion and weatherproofing. Always refer to the manufacturer’s installation guide for step-by-step instructions and best practices.

Polybit Bituboard is designed for roofing substrates such as metal, concrete, and wood decking. Substrates should be clean, dry, flat, and free of debris. Use primer or bonding agents as recommended and ensure the surface is compatible with the chosen fastening or adhesive method.
