Inverted roofs: Why choose Soprema?

Inverted roof systems are a popular choice for flat and low-sloped roofs due to their energy efficiency, moisture resistance and easy installation. Soprema is a leading manufacturer of inverted roof solutions, offering a range of high-quality products, backed by a strong technical team and warranties for the entire system. One of our most popular inverted roof systems is the Broof(t4) compliant, DUOFLEX hotmelt with SOPRA XPS insulation structural waterproofing system, which comes with a 40-year warranty.

Insulation

SOPRA XPS is a C2C certified rigid thermal insulation board made of XPS foam produced by Soprema from recycled EPS according to climate-friendly CO2 technology. It is primarily used as thermal insulation for zero fall, flat and pitched roofs, floor and underground constructions. On zero fall and flat roofs, it must be used in combination with ballast.

One of the major advantages of using SOPRA XPS insulation in an inverted roof system is its well-known outstanding energy efficiency, exceptional compressive strength and excellent moisture resistance. It is also easy to install and has application versatility, making it an ideal choice for many roofing applications, including inverted roof systems.

Waterproofing

Soprema’s DUOFLEX waterproofing system is an ideal inverted roof solution. It incorporates a high-quality elastomeric bitumen which is hot-bonded to the substrate, incorporating fleece within the system. The result is a flexible, 100% homogeneously bonded to the structure waterproofing system with self-healing properties that is quick and easy to install, perfect for phased works, durable, robust and designed to last the lifetime of the structure.
