SIKA Rmax ECOMAXci FR Air Barrier

Building contractors nationwide are currently facing shortages for popular mineral wool products used in building insulation, leaving contractors scrambling to restructure timelines or find alternative solutions. Fortunately, Sika Rmax has a solution that could ‘save the day’ and ensure both commercial and residential construction projects stay on track using a polyiso insulation board – Rmax ECOMAXci® FR Air Barrier.

Mineral wool insulation boards are typically chosen for their non-combustible properties and permeable exterior assembly. However, considering NFPA 285 compliance and moisture management, these properties become less crucial. Additionally, rain screen claddings, commonly used for combustible applications, are not ideal for mineral wool due to their tendency to retain moisture, leading to a decline in effectiveness over time.

Substituting with Polyiso has a myriad of benefits, which are outlined below:

Why Rmax Polyiso:

  • Higher R-Value: Rmax Polyiso offers a higher R-value per inch, compared to mineral wool, allowing cladding to be secured closer to structural studs, thereby eliminating the need for expensive cladding attachment systems.
  • Water and Vapor Resistance: Unlike mineral wool, Polyiso is unaffected by exposure to water and vapor, ensuring long-term performance and stability.
  • Faster Installation: Polyiso enables faster installation methods and can eliminate the need for secondary air barriers, resulting in lower labor costs and overall project expenses.
  • NFPA 285 Compliance: Rmax Polyiso assemblies meet NFPA 285 requirements for all common claddings in today's construction, providing peace of mind regarding fire safety regulations.
  • Sustainable Impact: Polyiso significantly reduces fossil fuel consumption, equivalent to planting 3.4 million trees for every 10% reduction in energy usage across 9 billion square feet of roofing area represented by BOMA. Additionally, it boasts the highest thermal efficiency, uses blowing agents with zero ozone depletion and global warming potential, and incorporates recycled materials.
  • Immediate Availability: With Rmax Polyiso, there's no waiting for material availability. It's readily accessible to meet project timelines.

Comparison with Other Systems:

  • Compared to Mineral Wool: Rmax Polyiso offers a thinner profile for the same R-value, lower cost, and superior performance over time.
  • Compared to XPS: Rmax Polyiso boasts higher R-values, faster installation, and reduced attachment complexity compared to XPS systems.
  • Superior Performance: Rmax Polyiso surpasses other rigid board solutions in terms of R-value, compressive strength, and durability, ensuring long-lasting performance and cost-effectiveness.
