About Amdrain Foundation Insulation
Amdrain is a two-in-one rigid Expanded Polystyrene (EPS) insulation board with integrated drainage channels. The panel is designed to be used in both exterior and interior applications for below grade foundation walls. The inner side (in contact with foundation wall) has vertical grooves (9/16”/14.2mm deep) creating small air gaps and allowing for moisture drainage while the opposite side is flat.
Amdrain EPS panel comes in 4’x8’ (1.22m x 2.44m) sheets with the thickness ranging from 1.5” (38mm) to 5” (127mm). The panels are designed to be installed in the vertical orientation only. The tongue and groove interlock helps maintain the continuity of the insulation eliminating the need for taping of the joints.

Building with Amdrain
Superior Thermal Insulator
Amdrain has exceptional long-term R-value retention as well as increased thermal resistance in lower temperatures.
No Risk of Trapped Moisture
Made from EPS with high permeance to allow the passage of water vapor.
Easy to Install
Amdrain foundation insulation is installed with no special tools, equipment or skills.
Durable
Has excellent resistance to mold, mildew and maintains its performance over time.
Moisture Management
When installed on the interior, the vertical grooves provide a drainage plane separating potential condensation from the wood framing.
Additional Protection for Waterproofing and Damp Proofing Systems
Provides additional protection during backfill to the waterproofing and/or damp roofing system installed on the foundation wall.
Improved Drainage
When installed on the exterior, the vertical grooves provide an additional drainage plane relieving any hydrostatic pressure, allowing moisture to be redirected down to foundation drain.

About EPS
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.
