What is Rmax Insulation?

Rmax Insulation is a trusted name in polyisocyanurate (polyiso) insulation boards, designed to deliver high thermal efficiency for roofs, walls, ceilings, and foundations. Available through Roofing4US, Rmax products are engineered to meet stringent energy codes while offering superior moisture resistance, fire performance, and durability. Whether you’re insulating a home, commercial building, or industrial site, Rmax helps reduce heat loss and improve energy performance.

How Does Rmax Insulation Work?

Rmax insulation boards feature a rigid polyiso foam core that slows down heat transfer. This keeps warm air inside during winter and blocks excess heat during summer. Many products in the range also include foil or fibreglass facers that act as reflective barriers and moisture shields. Some models, like Thermasheath®-SI, go further by combining insulation and structural support, reducing the need for separate sheathing materials.

R-Seal Insulation Flashing & Joint Tape

In the pursuit of creating a complete and robust insulating system, Rmax R-Seal insulation flashing is a quintessential component, available in various sizes, from 4" x 50' to 12" x 50', ensuring compatibility and functionality with numerous applications. Whether you’re working on a residential roof or a large commercial project, the assorted sizes cater to both minor and significant requirements, ensuring seams, joints, and edges are sealed to perfection.

Similarly, Rmax R-Seal 3000 and 3000w Insulation Joint Tape, along with R-Seal Insulation Construction Tape, available in rolls of various widths, offer enhanced sealing capabilities. Primarily utilized to bind insulation boards together, these tapes are designed to create a thorough seal, bolstering the overall integrity and effectiveness of the insulation system. It’s worth noting that both these products (flashing and tape) work hand in hand, acting as a defensive duo against thermal bridging and potential leak paths.

Insulation Boards

The Rmax Insulation Boards are manufactured to provide effective insulation solutions for a myriad of applications. Let’s explore:

RMax TSX-8510 and ECOMAXci FR are specifically crafted to serve as a reliable and efficient thermal barrier. Ideal for a range of buildings, they ensure energy efficiency by maintaining optimal interior temperatures. Different thickness options provide adaptability in diverse usage scenarios, ensuring both economic and energy-effective solutions.

Rmax ECOMAXci Air Barrier boards offer the dual functionality of insulating and air sealing, safeguarding interiors from exterior weather conditions, thereby ensuring thermal efficacy and optimal indoor comfort.

RMax Durasheath®3 and Thermasheath insulation boards offer an effective solution for walls and roofs, providing a strong thermal barrier against fluctuating external temperatures, ensuring interiors remain regulated and energy-efficient.

Rmax Ultra Max HD High-Density CoverBoard offers an additional layer of protection and reinforcement to your roofing system, ensuring a shield against physical damage and a concurrent thermal insulation layer, boosting the resilience and longevity of the overall roof structure.

Specialized Insulation Boards

Rmax Recover Board serves as an indispensable resource in restoration projects. When an existing roof needs an overhaul without dismantling the primary structure, this board provides the needed insulation layer while ensuring minimal added weight and optimal thermal performance.

Rmax Ultra Max and Multi Max boards, available in a variety of thicknesses, are recognized for their versatility in applications and robust thermal performance. Be it in walls, roofs, or other specialized applications, these boards impart remarkable insulating properties, ensuring structures are energy-efficient and compliant with regulatory standards.

Selecting the Right RMax Product

Choosing the right RMax product necessitates considering a few pivotal aspects:

1. Thermal Requirements: Different boards offer varied R-values (thermal resistance). Select a product that aligns with the specific thermal insulation needs of your project.
2. Application Type: Some products, like the Recover Board, are specialized for particular applications (e.g., restoration). Ensure the chosen board is apt for your specific use-case scenario.
3. Size and Dimensions: Be mindful of the size and thickness needs of your project. Utilize R-Seal Insulation Flashing and Tape to seal joints effectively when multiple boards are employed.
