Case study salesforce tower.
For more than 35 years rmax has been creating insulation solutions based on the latest building science.
Both are closed cell foam products.
Foil faced polyiso products have higher long term r values compared to other rigid board products.
We offer dow thermax polyisocyanurate and dow styrofoam xps extruded polystyrene known as blue board.
The ashrae prescriptive continuous insulation requirements for steel framed above grade walls recognize this phenomenon and in most climate zones call for a layer of continuous insulation ci to be added to the assembly to help stop the steel thermal shorts that can decrease the energy efficiency of the wall system.
