About Amrad: Insulated Radon Gas Mitigation Panel
Amrad is an insulated under slab depressurization panel and a key component in a radon gas mitigation system. The void created by the integrated channels serve as an air gap for soil gas collection. Radon gas is able to vent out to the exterior through the use of a connected PVC piping with a continuously running exhaust fan. This panelized solution with its unique channel design, void percentage, film and foam density creates a strong and durable panel, giving builders the ability to build an insulated concrete slab while meeting radon building code requirements and improving the indoor air quality for the occupants.
The channel pattern and ratio of solid to empty allows Amrad to replace 4” (102mm) of clean granular fill as normally required by the building code. In addition, the air gap created by the channels serves as a capillary break between the soil and slab, greatly reducing moisture related issues. Amrad’s High Impact Polystyrene (HIPS) film serves a dual function by providing the required vapor barrier under the concrete slab while acting as an air barrier to prevent any radon gas from infiltrating into the interior space. The Amrad film replaces the need for a dedicated soil gas retarding membrane as required by the building code.

It is available in a variety of compressive strengths and has superior bonding capabilities. Best of all, EPS will save you time and money. So the real question is: Why not EPS?
Amrad Panel Benefits
Superior Thermal Insulator
Amrad has exceptional Long-Term R-Value Retention (LTTR) as well as increased thermal resistance in lower temperatures.
Durable, Lightweight, Flexible
Each panel is easy to handle due to the low weight and can be easily cut.
Improved Indoor Air Quality
Amrad does not contain CFCs or HCFCs, no off-gassing and does not promote growth of mold and mildew.
Increases Comfort & Energy Savings
Acts as continuous insulation in the building envelope, reducing thermal bridging and energy consumption while improving comfort.
Built-in Air & Vapor Barriers
When the joints are taped and sealed functions as both an air and vapor barrier.
EPS foam can be recycled and uses only steam and water during manufacturing.
Shaping A More Sustainable World
Sustainability is one of our top priorities, both for our products themselves and for what our products make possible. Manufactured without ozone-damaging compounds, recyclable and endlessly reusable, EPS has a smaller carbon footprint and results in less pollution than the manufacturing of alternative materials. And EPS helps create a more sustainable world by making buildings more energy efficient, reducing greenhouse gas emissions, preventing product damage and waste, and reducing shipping fuel usage, just to name a few. We’re constantly working to find new ways to be good stewards of our customers’ visions and of our environment.
