Kingspan Optim-R Flooring System

Kingspan OPTIM-R Flooring System is an optimum performing insulation with a declared thermal conductivity of 0.007 W/mK. The Kingspan OPTIM-R Flooring System provides up to five times higher insulating performance than other commonly available insulation materials, with an aged design value thermal conductivity of 0.007 W/mK.

Product Applications

The OPTIM-R Flooring System consists of vacuum insulated panels and rigid thermoset infill panels that can be trimmed to fit around problem areas like penetrations and load-bearing walls. In retrofit applications, the System provides solutions for regions that would have previously remained uninsulated due to a lack of space or the impracticality of material excavation.

Advantages of Kingspan Optim-R

The Kingspan OPTIM-R Flooring System can dramatically improve U-values in regions that would usually be considered a detriment to overall thermal performance in new builds. Optim-R has qualities that no other Kingspan insulation board can match.
