Aug 06, 2021· - They preclude stepping down the grade to suit site conditions, meaning they only work on those rare completely flat sites, or necessitate building up the grade round the house which can lead to an awkward relationship with the existing site. - They rely on exterior insulation, which here in the PNW means vulnerability to carpenter ants.
Other Insulation Applications Perlite insulation is an inorganic product that does not support combustion, or rot, nor does it provide a habitat for rodents. It is ideal for use under concrete slabs, in chimneys and in high-temperature applications such as pizza ovens and rocket stoves.
For this reason, a larger safety margin is used in the design of plain concrete construction than in reinforced concrete construction. Steel reinforcement is available in Grade 40 or Grade 60; the grade number refers to the minimum tensile yield strength of the steel (Grade 40 is minimum 40 ksi steel and Grade 60 is minimum 60 ksi steel).
