Enviroslab Perimeter Foundation Solution
Enviroslab is a non-structural, rigid insulation form made from closed cell Expanded Polystyrene (EPS) offering cost effective performance.
Improved R-Value for the Foundation Perimeter
Designed to be installed as pre-cut insulated forms for shallow frost walls, reduce thermal bridging, and directly improve building envelope performance.
Enviroslab’s exceptionally low, long term, in-service water absorption properties allow it to maintain its specified thermal performance and durability when installed for slab on grade or below grade applications.
