INFRA panels

Intended use

The Finnfoam INFRA panels were designed to be used as a distributive layer and frost insulation for subsoil with a low bearing capacity or susceptibility to freezing.
Properties
The size of the Finnfoam INFRA panel is 600 x 2,600 mm and the panels are available with a thickness of 50 mm. If the site requires thicker insulation for frost protection, this can be achieved by using standard Finnfoam panels in addition to the INFRA panels. The overall thickness of insulation is chosen according to the number of chilling hours in the area and the installation depth as per the standard procedure for designing frost protection. The short-term compressive strength of the panels is ≥ 400 kPa and the long-term compressive strength is ≥ 180 kPa. The modulus of elasticity of the Finnfoam INFRA panels is ≥ 19,000 kPa and the bending strength at 50 mm ≥ 1,200 kPa.
Operating principle
The bearing capacity of the mortar coated Finnfoam INFRA panel is significantly higher than that of standard Finnfoam. This allows you to create a distributive layer on top of foundation soil with a low bearing capacity. This solution can be used to provide significant savings in foundation costs, as a road or sidewalk can be founded without extensive replacement/stabilization of soil. Standard Finnfoam can also be used to significantly reduce the replacement of soil, but this solution will provide even more benefits.
