What kind of floor insulation used in your facility?

It’s XPS, right

Extruded Polystyrene (XPS) has a closed cell structure with high compressive strength coupled with moisture resistance makes it the material of choice for protecting the building envelope from heat ingress.

The closed cell structure with continuous skin formed on front and back surfaces retains its excellent 'R' value year after year even after prolonged exposure to humidity, condensation, ground water and freeze/thaw cycling.

Some features –

Excellent long-term stable insulating performance of R-51 per inch. Exceptional moisture resistance, long-term durability. Reusable. Lightweight, durable rigid foam panels are easy to handle and install. Easy to saw, cut or score
