Applying the Soprema duo-tack insulation adhesive to this vapour barrier on the concrete deck of Baro in Toronto for Intor Construction. The duo-tack must be applied in 12″ ribbons and the insulation must be laid in the adhesive. This poly-iso insulation was a 3″ base layer. We installed a 2% tapered poly-iso system on top of this base layer which is also adhered with duo-tack. We then adhered 1/8″ thick sopraboard on top before installing the SBS Modified Bitumen Soprema Sopralene Flam 180 Base sheet and 250 Cap Sheet.
