Durability and Lightweight
Increased Thermal Performance
SilveRboard® Reflective & Under Slab Insulation
SilveRboard® is a rigid insulation board made from Expanded Polystyrene (EPS) covered with a layer of polypropylene reflective lamination on both sides. This highly effective combination of materials offers high compressive strength and great thermal performance when used in below grade and under slab applications.
The double-sided lamination dramatically increases board strength and flexibility, reducing site damage and waste. The availability of larger panels and laminated film help improve job site efficiency and reduce labor costs.

The Alleguard Advantage
With a combined 60-year history and proven track record of supporting our customers’ visions, Alleguard is strategically built from the ground up to expand and shape your business. Whether you’re in construction, protective packaging, cold-chain or other industries, we are relentless in going the extra mile to help your business succeed.
EPS has high R-value retention, is fully recyclable, and is easily customizable. EPS is made without ozone-harming compounds or any kind of dye. 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?
Building with SilveRboard®
Superior Thermal Insulator
SilveRboard® has exceptional long-term R-value retention as well as increased thermal resistance in lower temperatures.
Built-in Water & Vapor Barriers
When the joints are taped and sealed it can function as a vapor barrier.
Durable, Lightweight, & Flexible
Each panel is easy to handle due to the low weight and can be easily cut.
Improved Indoor Air Quality
SilveRboard does not contain CFCs or HCFCs, no off-gassing and does not promote growth of mold and mildew.
EPS foam can be recycled and uses only steam and water during manufacturing.
Increases Comfort & Energy Savings
Acts as continuous insulation in the building envelope, reducing thermal bridging and energy consumption while improving home owner comfort.
SilveRboard® Projects & Applications
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.
