INTERNAL AND EXTERNAL CORNERS IN TPO are suitable for the reinforcement of the waterproofing in internal and external corners. The above elements should not be used as a substitute of the original waterproofing product, they have been created for a secondary protection and reinforcement of those areas of higher risk because of transversal and horizontal traction of the waterproofing membrane. They are used for application on roofs waterproofed with TPO membranes The Internal and external corners are made of soft, flexible and UV stabilized TPO. It offers high physical, chemical and technical properties as well as a flexible product. It is highly resistant to UV rays, ozone and other atmospheric and chemical agents. It can be used in a wide temperature range and is extremely flexible at low temperatures, it is stable over time thanks to the physical and mechanical properties, which therefore assure maximum performance throughout its lifespan.
