Rboard® Rigid Foam Insulation - Wall Sheathing
There are many different ways to go when it comes to wall sheathing, but if you’re looking for an environmental-friendly option, Polyisocyanurate (polyiso) is the best option. Atlas Rboard® rigid foam insulation is a closed cell polyisocyanurate foam core, faced with a non-reflective coated glass-mat facer on both sides.
Rboard® combines high R-value, enhanced durability from two coated glass-mat facers, and water resistive attributes in a high performance rigid insulation board. Wall sheathing is suitable for a variety of continuous insulation (CI) applications. It’s a flexible option that can be used with concrete, wood, wood stud, steel stud, glass-mat gypsum, air and vapor barrier membranes. Making it the perfect selection of wall sheathing for nearly any project. Atlas polyiso has been tested for VOC and formaldehyde emissions, in which reported emissions were below the maximum emission levels allowed under both the GREENGUARD and GREENGUARD Schools and Children criteria. These tests confirm that Atlas polyiso insulation systems are all very low-emitting products, making it one of the best environmental-friendly options as previously mentioned.
Panel sizes are 4' by 8' or 4' by 9'. Insulation panels can be supplied in nominal 16" or 24" widths for use in cavity wall applications. Custom sizes are also available.
Glass-Mat Facers. The Ultimate Alternative.
Discover the alternative to foil faced boards. The Atlas Wall CI Board line includes coated glass-mat facers, a best-practice building method throughout North America. These high-performance and durable, coated glass-mat facers protect the building while the walls are exposed during construction.
It’s a great go-to wall sheath when you prefer a more vapor open and durable facing compared to foil. Rboard bonds aggressively to most trowel applied, fluid/ liquid applied and “peel and stick” water resistant barriers. Rboard can be used in many “combustible construction” projects such as Type V commercial buildings, multifamily and single-family residential construction.
They are also widely accepted in the building industry, with hundreds of materials tested to work with them as a system – including spray-applied air barriers, peel-and-stick membranes, and more. Coated glass-mat facers have a great installed track record, too. It’s another reason to choose Atlas polyiso for your next project.
