Eps Insulation Under Concrete Slab

Eps 3 xps 2 faced or unfaced.

Eps insulation under concrete slab.

An overly conservative design approach often results in specification of a high compressive resistance xps product when a more cost effective eps. Take the case of a warehouse with a 6 inch thick 2 500 psi concrete slab on 2 inches of eps insulation with a rated stiffness of 360 psi for one inch. When building a slab on grade eps rigid foam insulation is the most common choice of insulation for performance and cost. Eps offers a number of advantages over the more commonly installed xps including having the highest r value per dollar among rigid insulations.

Faced 2 unfaced 3 insulation features. Xps and eps rigid insulation is used under concrete slabs. Under slab 3 more ways to filter. Formaldehyde free 3 structural 2 vapor retardant 2 insulation r value.

Unitherm is made from unipoly a light weight moulded polystyrene material with exceptional thermal insulation properties. Eps 3 xps 2 faced or unfaced. Spray foam for sure has uses where it is the best choice by a long shot but under a slab is not the place. Say you use an average and relatively inexpensive rating of 40 psi then the insulation will support.

Eps insulation blocks can be custom cut into a variety of shapes and sizes to meet wide ranging job specifications. Historically used as a stable roof insulation eps has gained wide acceptance in wall below grade and under slab applications due to its low moisture absorption strength and stable long term thermal performance.

Forklifts to be used in the building impart 8 000 pounds of force at the wheel which has a 6 inch by 10 inch tire footprint on the slab.

Eps insulation in an under slab application. Yet concrete slabs distribute loads more uniformly than this which means the insulation does not need as high of a compressive resistance as when one assumes a concentrated triangular load path.

I wouldn t go as far as saying you couldn t use spray foam below a slab but i m not sure why you d want to. Concrete 4 existing drywall 2. As insulation becomes increasingly common on foundations and under slabs understanding the performance and cost factors of the different materials is important for successful bids and profitability.
