ONDUTISS
ONDUTISS®: a large range of membranes for Pitched Roofs, Facades and Walls protection
ONDUTISS® offers a large range of underlay membranes designed to optimise the protection of buildings and their occupants. An underlay membrane, often referred to as underlayment, is a critical component in roofing and facade systems.
There are different types of membranes, all contributing to keeping a building dry, comfortable, and energy-efficient:
• Membranes play a vital role in the building's waterproofing system: during construction, underlayments quickly weatherproof the building in the event of rain. Over the years, these membranes act as a barrier against potential leaks from the primary roofing or cladding material.
• Membranes play a crucial role in the essential ventilation of the building, protecting insulation and maintaining its optimal performance. They enable natural ventilation by managing vapour evacuation, preventing excess moisture in the roof and wall spaces, which could condense into liquid water and cause mould. Mould is a serious threat to air quality, insulation performance, wood structure durability, and the aesthetics of drywalls. Ultimately, it impacts living comfort and the energy required to heat or cool a house.
• Membranes also protect the building and its carpentry by acting as a barrier against wind uplift forces that could displace tile covers or cladding materials. This is particularly crucial in cold roof constructions without a deck under the primary roof cover. Finally, membranes prevent dust and insect penetration into roof and wall areas.
Several specialised membranes offer additional benefits. Reflective membranes provide extra protection against heat intrusion in summer and heat loss in winter. Fire-resistant membranes act as an additional barrier against fire spread.

Easy to install
The Ondutiss range caters to various needs with specialised products for different applications:
• Roof Membranes/Underlays: designed for pitched roofs, discontinuous and full deck applications. Roof underlays offer high breathability and waterproofing. Installed on the cold side of the roof (i.e., over the insulation material, with or without an air gap in between), they function to evacuate vapour from the roof area and ensure waterproofing in case of a leak.
• Facade Membranes: like roof underlays, facade membranes provide breathability to evacuate water vapour from the building through the walls while acting as a waterproofing barrier, protecting insulation and drywalls. Facade membranes are always installed between the cladding material and the insulation.
• Roof and Wall Vapour Control Layers and Vapour Barriers: these membranes regulate or block vapour transmission from inside to outside and vice versa. They are essential for managing moisture levels, especially in regions with significant temperature differences (day/night, summer/winter) and in wood constructions.
• Construction Foils: various types of watertight membranes protect insulation from humidity, frame concrete, or serve as temporary solutions to protect a job site. Flooring membranes, for instance, separate insulation from concrete, blocking humidity. Standard foils can be used as temporary solutions during construction for reliable waterproofing.
