About High Density (HD) Envirosheet
High Density (HD) Envirosheet is a high density economical foam board insulation made from Expanded Polystyrene (EPS) offering a high R-value per dollar. It is a highly durable and cost-effective product that is primarily designed to be used for below grade applications for residential or commercial construction.
The closed-cell structure gives the board superior water resistive properties while the high density of the foam makes for an excellent alternative for projects where high compressive strength is required.
High Density (HD) Envirosheet comes in multiple densities and is available in a various sizes and thicknesses. The availability of larger panels helps improve job site efficiency and reduce labor cost. The high compressive strength makes it the ideal solution for majority of below grade applications such as foundation walls and below concrete slabs.

Building with High Density (HD) Envirosheet
Superior Thermal Insulator
Envirosheet has exceptional long-term R-value retention as well as increased thermal resistance in lower temperatures.
High compressive strength along with superior water resistance and durability.
Lightweight & Flexible
Each panel is easy to handle due to the low weight and is easily cut.
Improves Indoor Air Quality
Envirosheet 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.
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?
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.
