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.
High compressive strength floor insulation.
Offering insulation products across a broad temperature spectrum to fit your needs.
High performance floor insulation kingspan thermafloor tf70 is a high performance insulation with a fibre free rigid thermoset polyisocyanurate pir core.
Using an unnecessarily high strength insulation you end up paying for something you don t really need.
Available in 40 60 and 100 psi compressive strengths.
Short term testing compressive behaviour bs en 826 2013 and.
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.
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.
If that s right then why bother with 150 kpa pr even up to 500 kpa.
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.
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.
High compressive strength resists damage from heavy loads.
High compressive strength material can resist damage by foot traffic vibration and various forms of external pressure.
Compressive stress when the compressive strength is not reached the point at which the load stress causes a 10 relative deformation of the insulation.
Insulation compressive strength can be a very important design consideration.
High compressive strength rigid foam insulation features and benefi ts strength designed for use in high load bearing applications.
Foamular 400 600 1000 high compressive strength rigid foam insulation product data sheet 467 kb pdf technical bulletins.
It used to insulate solid concrete and suspended timber ground floors and has a thermal conductivity of 0 022 w mk.
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.
Note that increasing the thickness of eps insulation decreases the overall subgrade modulus.
