The features and properties of 3 leading technologies

From large commercial roofs to inverted roofs and parking decks, selecting the right insulation panels is critical to the success of the overall system.  Here, we take a look and the features and benefits of three leading SOPREMA technologies to help builders and contractors ensure they are choosing the right insulation for the job.

SOPRA ISOPolyisocynanurate: Slim and Effective  
Best suited for:  Conventional roof systems
Product: SOPRA-ISO

Polyisocyanurate insulation offers many benefits that make it the most effective thermal insulation product on the market. With the highest R-value in roofing among all types of insulation (R-5.7), these panels form a roof system that is slimmer yet more effective as the high dimensional stability of polyisocyanurate prevents the formation of thermal bridges in the roof system, which helps improve energy efficiency.  Lightweight and versatile, this insulation is easy to transport and handle, and it’s compatible with most solvents used in construction adhesives. Polyisocyanurate is still the only foam plastic insulation product to have both FM 4450 and CAN/ULC-S126 approvals when installed directly on a steel deck. Both tests are specifically referenced in many building codes.

XPSExtruded Polystyrene (XPS): Strong and versatile
Best suited for: Inverted roof systems (Protected Membrane Roofs systems)
Product: SOPRA-XPS

Extruded polystyrene insulation panels are made of closed-cell foam and are mainly used as thermal insulation for SOPREMA foundation systems, inverted roofs (including plaza decks and green roofs) and parking decks. This type of insulation has outstanding resistance to water and moisture thanks to its dense closed-cell composition. It is designed to perform in all applications, even in below-grade walls and inverted roofs. It adapts well to temperature changes, making it suitable in winter climates where freeze-thaw cycles are prevalent. Even when exposed to moisture, SOPRA-XPS is mould and bacteria resistant. Like Polyisocyanurate it is rigid, durable and meets CCMC requirements and is consistent with CAN ULC S701.1 standards.


Mineral Fibre: Naturally Permeable and Fire-resistant
Best suited for: All roof systems except inverted roofs; those seeking LEED credits

Mineral fibre insulation boards are versatile, multifunctional, and the most environmentally-responsible option on the market. They can be mounted on different types of roofs, either through heat bonding or cold-installed, or with bitumen and mechanically fastened. Composed largely of rock and slag, they are a non-combustible product with a melting point of approximately 1177 °C (2150 °F), giving them excellent fire resistance properties.  Additionally, these boards are naturally water repellent yet vapour permeable, offering excellent dimensional stability and excellent acoustic properties. Unlike several other insulating boards, SOPRAROCK stands out for its rot-proof characteristics; its R-value, and its high recycled materials content.  Not only are they versatile and environmentally friendly, but they also provide very quick access to firefighters, granting them those extra precious minutes they may need in the event of a fire, something no other insulation provides.
