A. Permanent is ideal for long pipe runs but not for any application where
ease of removal for maintenance and / or inspection is essential. Permanent insulation is
routinely installed by an outside contractor and is messy to remove [not replaceable] – it can
usually only be replaced by a contractor. Initial installation cost is usually less than removable
blankets. However replacement insulation obviously doubles the cost. This type of insulation is
cut and fitted on site.
