Köster™ TPO Waterproofing Membrane

Extremely economical

The long lifespan of more than 30 years, the use of material that is resycable, and a cost efficient production make KÖSTER TPO Premium a particularly economical waterproofing membrane. Especially when compared with PVC membranes, cost benefits are obtained across the entire lifespan.

Outstanding lifespan

Weatherproof, flexible, resistant against chemicals, homogenous: KÖSTER TPO Premium convinces through its richness of excellent material characteristics. The membranes expand with heat and contract in colder environmental conditions. Through this, damage due to thermal strain – e.g. shattering – is effectively prevented. When it comes to high quality, durable PE waterproofing, KÖSTER TPO Premium is the first choice.

Certified sustainability

Using recyclates, KÖSTER TPO Premium provides a positive contribution towards a sustainable building culture and thereby towards the fulfillment of criteria for a DGNB certificate. The ecological evaluation is based on the Environmental Product Declaration of the IBU (Institut für Bauen und Umwelt e.V.).

Easy and secure application

The excellent workability is a prominent feature of KÖSTER TPO Premium roofing membranes. The homogenous material composition of both the top and bottom layers ensures a simple, straightforward, and safe welding seam with a wide welding temperature window and a permanent weldability beyond common construction time frames. Chemical seam cleaning is not required.

Versatile

New construction or renovation: KÖSTER TPO Premium is suitable for all lightweight roof structures, bitumen compatible, and applicable on a variety of substrates.

Building and the Environment

The KÖSTER BAUCHEMIE AG is committed to protecting and preserving our environment. We combine the use of the most modern raw materials and production technologies in connection with constant research and development. This means that most materials are not only solvent-free but are also designed for minimal environmental impact and maximum safety for the installers. The KÖSTER BAUCHEMIE AG is also a member of the Institute for Building and the Environment, whose members are committed to sustainable construction. The basis for this is the transparent disclosure of all relevant product information, including the life cycle assessment data.

KÖSTER TPO roofing membranes are, at the same time, ecologically and economically advantageous because of their durability over decades and because of the low maintenance intensity. They protect buildings from water ingress, the most common and costly cause of building damage. Real estate is preserved longer, and essential resources are saved. In contrast to other roofing membranes, KÖSTER TPO roofing membranes do not release plasticizers into the environment and can be optimally recycled. They do not become brittle and are, therefore, more durable. KÖSTER TPO Roofing Membranes are an excellent base for green roofs.
