High Compressive Strength Floor Insulation

Note that increasing the thickness of eps insulation decreases the overall subgrade modulus.

High compressive strength floor insulation.

Moisture effective resistance against moisture mildew corrosion and rot. Short term testing compressive behaviour bs en 826 2013 and. High compressive strength material can resist damage by foot traffic vibration and various forms of external pressure. Insulation compressive strength can be a very important design consideration.

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. Compressive stress when the compressive strength is not reached the point at which the load stress causes a 10 relative deformation of the insulation. Foamular 400 600 1000 high compressive strength rigid foam insulation product data sheet 467 kb pdf technical bulletins. 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.

The greater the compressive strength the more durable the insulation. When identifying the compressive capabilities of an insulation material it undergoes two tests. Offering insulation products across a broad temperature spectrum to fit your needs. High compressive strength resists damage from heavy loads.

It used to insulate solid concrete and suspended timber ground floors and has a thermal conductivity of 0 022 w mk. High compressive strength rigid foam insulation features and benefi ts strength designed for use in high load bearing applications. 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. Available in 40 60 and 100 psi compressive strengths.

If that s right then why bother with 150 kpa pr even up to 500 kpa. Using an unnecessarily high strength insulation you end up paying for something you don t really need. 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. 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.

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.
