ONDUTISS STRONG

ONDUTISS,  a large range of membranes for Pitched Roofs.

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 an active role in the essential ventilation of the building, protecting insulation and maintaining its 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.

The Ondutiss strong caters to below need:

• Roof Membranes/Underlays: ideal 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.

These membranes are available through professional channels, including retailers specialising in building materials and specialised roofing points of sale or directly from Onduline Philippines. Whether you are a professional or a DIY enthusiast, Ondutiss membranes are accessible to meet your building protection needs.
