Our Below Grade Insulation Products
High-Density SilveRboard®
High Density (HD) 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.
High-Density 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.
Amrad
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.
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.
Amdry Eco: Laminated Multipurpose EPS
Amdry Eco is a non-structural rigid insulation panel made from closed cell, molded Expanded Polystyrene (EPS) with a layer of High Impact Polystyrene (HIPS) film. The laminated side has bi-directional 1/2” (13mm) wide by 1/2” (13mm) high channels that can be used for venting or water drainage, depending on the application.
The combination of molded EPS, HIPS film and moisture management pattern offers a highly versatile supplementary component that can be used in floor assemblies.
