With Neopor®, it is safe to say a little goes a long way.


Neopor is powerful Insulation.





Neopor is Energy Efficient... for a long, long time.

Neopor’s unique silver-gray color and exceptional insulation characteristics are a result of high-purity graphite integrated into the polymer matrix. Graphite reflects and absorbs radiant energy, decreasing the materials thermal conductivity and increasing it’s R-value. Neopor has a long-term stable R-value ranging from 4.5 – 4.9 per inch at 75F, depending on density.

When it’s cold outside, Neopor powers up!

The R-value of Neopor actually increases as temperature decreases. And, as temperatures decrease, the high-purity graphite integrated into the polymer matrix of Neopor contributes more to slowing the flow of heat through the material. This means, when compared to other polystyrene-based rigid foams and to polyisocyanurate rigid foam, Neopor maintains more of its R-value when temperatures drop.


Breathe easy with Neopor.

Neopor is GreenGuard certified for Indoor Air Quality. Neopor does not use fluorocarbons (CFC, HFC, HCFC) as an expansion agent. Pentane, used during the manufacturing process as an expansion agent, has zero Ozone Depletion Potential and very-low Global Warming Potential and can be reclaimed for use in energy production for the manufacturing process.


Neopor is ‘Adaptable’.

Neopor Rigid Thermal Insulation is adaptable in size, thickness, shape and density. This means no more gluing together multiple boards to get 4 inches of insulation. This means you can hit your R-value target in a thickness-constrained application. Monolithic ‘boards’ can be produced in thicknesses up to 48” and Neopor can be shape molded with corners and interlocking features ‘built-in’.


Water and Neopor are good friends.

Neopor Rigid Thermal Insulation is a closed- cell foam, but not all closed-cell foams are created equally. Neopor Rigid Thermal has a Class III Vapor Permeability rating of between 2.5 and 5.5 depending on thickness and density. This means walls constructed with Neopor as Continuous Insulation can more easily transport water vapor, reducing the likelihood of mold, mildew and structural damage. And, Neopor Rigid Thermal Insulation has low water absorption relative to traditional insulation materials.


Discover the marriage of Quality and Cost Effectiveness.

Don’t be fooled by “gray foam’’ that doesn’t carry the Neopor Trademark. Products made of Neopor carry the Neopor trademark as an Ingredient Brand. Neopor Rigid Thermal Insulation is produced in the US and Canada under a Brand Marketing Program. Manufacturers adhere to a set of quality guidelines which help ensure finished goods made of, and Ingredient Branded as made of, Neopor are of consistent quality throughout North America. Neopor leverages a network of manufacturers and uses a manufacturing process proven to provide cost effective rigid thermal insulation.


Neopor® Rigid Thermal Insulation is today’s eco-efficient and cost-effective 'Meet Code' insulation solution for architects, contractors and building owners.
