DESCRIPTION
SitaMulti rainwater outlets are a robust cast-iron construction providing for use in applications with increased fire performance requirements – particularly in conjunction with Radmat non-combustible insulation roofing systems. The SitaMulti features a clamping ring arrangement for mechanical connection to the surrounding waterproofing system. A telescopic Extension Unit of the same dimensions can have the spigot cut (to suit the depth of insulation) to provide a thermally-efficient configuration – installation can be aided with the inclusion of a pre-fabricated insulating body moulded in cellular glass foam insulation.
