For more than 35 years, Rmax has been creating insulation solutions based on the latest building science. Our full line of high-quality, polyiso-based wall and specialty insulation products for commercial, residential, and industrial applications deliver maximum R-values and minimum environmental impact with efficiency in installation, cost, and design.
Rmax insulation has been designed and tested to provide building envelopes with superior insulating protection while meeting the newest codes and requirements. Rmax products are leaders in both performance and environmental sustainability. Rmax offers polyiso products to meet the needs of any application.
Rmax’s engineered products and solutions allow for ultimate efficiency through multiple design options, ease of construction, and reduced energy usage. This leads to a better building envelope while adding to the bottom-line through both material and labor savings - making Rmax an excellent choice for commercial and residential applications. Whatever the application, Rmax is there to deliver performance and quality!
Leaders in Continuous Insulation
Continuous insulation (CI), as defined by ASHRAE 90.1, is:
“Insulation that is uncompressed and continuous across all structural members without thermal bridges other than fasteners and service openings. It is installed on the interior, exterior, or is integral to any opaque surface of the building envelope.”
Instead of cavity insulation that fills the voids between studs, continuous insulation wraps the exterior of a building in a continuous layer of insulation that covers any “holes” where heat could have otherwise leaked through the building envelope.
Increased desires for energy efficiency and overall better building practices have pushed standards to require CI in more applications. Rmax polyiso can meet the increased material requirements needed in a continuous insulation product. High dimensional stability, resistance to chemicals and mold, and facers that provide built-in air and vapor barriers are just some of the features that make Rmax polyiso exceptional. As leaders in creating insulation based solutions, Rmax is on the forefront of delivering insulation to meet new and varied needs.
Polyiso’s Evolution
Once a product used almost exclusively in wall construction, polyiso has evolved into a product with attributes that allow it to be applied to a variety of different applications.
Originally made using ozone depleting blowing agents, polyiso has continued to evolve and improve in both performance and environmental sustainability. Now produced with a high percentage of recycled materials, Rmax polyiso is a green solution for building projects.
Polyiso is not just a green solution during manufacturing. The benefits continue for the life of the insulation. Because of polyiso’s incredible thermal performance, Rmax polyiso reduces the energy consumption of buildings where it is used for the life of the building. This decrease in energy usage is just another part of polyiso’s green lifecycle.
Fire and Water
Part of what makes Rmax polyiso special is the characteristics the insulation panels have outside of their thermal performance. Rmax polyiso can take on both water and fire. With properly treated joints, polyiso panels can function as a water-resistive barrier that results in labor savings and a tighter building envelope. Polyiso can withstand moisture exposure without being damaged or losing its performance characteristics which sets it apart from many other insulation types.
An interesting phenomenon occurs when Rmax polyiso is exposed to fire. Instead of melting like other insulation types, Rmax polyiso chars and hardens. Unlike other insulation types, Rmax polyiso does not require a tradeoff between energy efficiency and building safety. With Rmax polyiso, you get the best of both worlds.
The Rmax Polyiso Advantage
When used in wall assemblies, polyiso brings great advantages to building construction. With great strength and dimensional stability, Rmax polyiso is easy to work with and installation is a breeze. Built-in facers also allow Rmax polyiso to be easily tailored to the application where it is being used.
Common construction applications for Rmax polyiso include:
Stud walls
Cavity walls
Masonry walls
Exterior stucco
Re-siding
Vaulted-ceilings
Attics and crawl spaces
Limited roofing
With all of the certifications and ratings that come with Rmax polyiso, you can rest assured that the polyiso will be up to the test no matter how it is used.
