10 Reasons to Choose Polyisocyanurate-based Insulation Boards for Your Wall Construction Assemblies

Published by SOPREMA

Polyisocyanurate insulation boards are known for their versatility, but also for their many benefits – which make this product an advantageous solution when it comes to designing efficient wall construction assemblies. Here is a list of 10 reasons to choose SOPRA-ISO V polyisocyanurate-based insulation boards for your projects.

1. High Thermal Efficiency

With the highest R-value per inch in the roofing industry, based on LTTR (long-term thermal resistance), it is the most effective thermal insulation product on the market. Systems with polyisocyanurate are thinner than with other technologies, which reduces the building footprint and construction costs.

2. Sustainability

Since polyisocyanurate systems are rigid, they require fewer fasteners than other insulating products, which reduces costs, installation time and thermal bridges. Moreover, thanks to this rigidity, the product will not collapse, which would lead it to deteriorate or lose its thermal performance over the building’s service life. Its surface is also one of the most efficient on the rigid board market.

3. Easy Installation

No specific training is required for installing this lightweight and easy-to-position product. In addition to having a constant factory-controlled thickness, its low weight simplifies transport and handling.

4. A Popular Technology

Polyisocyanurate is a technology that has been used for many years, and it has acquired a good reputation in the construction industry.

5. Mould Barrier

With their closed-cell core and coatings (aluminum coating or glass fibre non-reflective coating), SOPRA-ISO V boards are hydrophobic. Thus, the product will not contribute to mould growth.

6. Compatibility

There will be no unpleasant surprises as these boards are compatible with most solvents used in construction adhesives.

7. Environmentally Friendly

SOPRA-ISO V boards contain no chlorofluorocarbon (CFC) or hydrochlorofluorocarbon (HCFC).

8. Double Function

When properly installed, it can act as two products in one: an insulating board and a weather barrier. Thus, you gain continuous insulation and obtain excellent energy performance, while having an economic product that doesn’t require the addition of any other membrane.

9. Leed Credits

Polyisocyanurate boards can help in obtaining numerous LEED credits. Here is the list of credit categories under LEED v3 and LEED v4:

  • Energy and Atmosphere
  • Innovation in Design
  • Materials and Resources
  • Indoor Environmental Quality

10. Designed for All Types of Constructions

The SOPRA-ISO V boards are designed for all types of buildings: industrial, commercial, institutional and residential. They can be used with anchors or adhesive on most surfaces, such as concrete, wood, wood studs, steel studs, external gypsum and air/vapour barrier waterproofing membranes.
