SOPRA-ISO : The Unbeatable Polyiso

There are several products for standard and commercial roof insulation on the market: polyisocyanurate, rock wool, expanded polystyrene… Construction professionals have access to a wide selection when it comes to choosing a roof insulation product. Obviously, these technologies do not all have the same features and performance, and a person can quickly get lost among all the misleading or ambiguous information.

To choose the right insulation, it is important to consider a global perspective and not focus on a single feature. If you take the big picture into account, you will understand why polyisocyanurate remains the optimal solution for conventional roof insulation.

Here are the aspects to consider regarding polyisocyanurate, which will be addressed in this bulletin:

• The actual R-value at low temperatures.
• The difference between the actual thermal performance and that stated on the data sheet.
• The importance of lighter weight for the design of a building structure.
• Why good compressive strength is a must.

In short, see why polyisocyanurate performs better than other insulation products throughout the year, at the time of installation as much as over the long run.
