High compressive strength floor insulation. Short term testing compressive behaviour bs en 826 2013 and. Available in 40 60 and 100 psi compressive strengths. Moisture effective resistance against moisture mildew corrosion and rot. Astm c578 types and physical properties for foamular xps 106 kb pdf foamular extruded polystyrene insulation for cold storage applications technical guide 884 kb pdf.

It used to insulate solid concrete and suspended timber ground floors and has a thermal conductivity of 0 022 w mk. If that s right then why bother with 150 kpa pr even up to 500 kpa. Note that increasing the thickness of eps insulation decreases the overall subgrade modulus. High compressive strength resists damage from heavy loads.

The highest kn m2 i have is 7 5 for boiler rooms plant rooms including weight of machinery. A common design assumption leads to specification of rigid foam strengths that are many orders of magnitude higher than necessary which can double the insulation. So does this mean an insulation board with a kpa of 70 compression strength at 10 compression and 20 compression strength at 1 compression is plenty for a garage floor. Using the above method to determine the pressure that a slab transfers to the subgrade allows for proper specification of rigid foam insulation and avoids over engineering the insulation for compressive strength.

Target an appropriate compressive strength one of the best ways to save money on rigid foam insulation installed under concrete slabs is to ensure the material is not over engineered. Insulation compressive strength can be a very important design consideration. Offering insulation products across a broad temperature spectrum to fit your needs. Compressive stress when the compressive strength is not reached the point at which the load stress causes a 10 relative deformation of the insulation.

When identifying the compressive capabilities of an insulation material it undergoes two tests. Newly launched high compressive strength products the owens corning thermafiber rainbarrier high compressive portfolio uses thermacrimp technology to make the highest compressive strength mineral wool ci on the market. High compressive strength material can resist damage by foot traffic vibration and various forms of external pressure. The greater the compressive strength the more durable the insulation.

Since eps is lower cost per inch than xps and is available in a range of compressive strengths from 10 to 60 psi using it belowgrade and under slabs can save on insulation costs.
