ProTherm PIR B tapered is a tapered rigid Polyisocyanurate (PIR) foam insulation for use in bituminous roofing-systems on suitable surfaces. As part of a tapered roofing scheme ProTherm PIR B tapered provides roof surfaces with a finished fall of either 1:60 or 1:80.
ProTherm PIR B tapered is a rigid Polyisocyanurate (PIR) foam core faced with bitumen coated glassfibre tissue on one side and polypropylene fleece on the other. The PIR foam core is temperature tolerant and withstands the application of hot bitumen to the surface temperature of 240°C.
For a comprehensive NBS J42 or J41 specification contract Radmat Building Products.
ProTherm PIR B tapered is compliant with BS 4841-4:2006, BBA No. 07/4487
ProTherm PIR B tapered is bonded to the EshaBase vapour layer or a prepared existing roof surface with EshaStik PU Adhesive. Individual ProTherm PIR B tapered boards should be laid with the bitumen tissue side up with edges butted and in a break bond pattern laid at right angles to the edges of the roof or diagonally across the roof.
When applying ProTherm PIR B tapered on existing bituminous or sanded substrate the surface must be prepared in accordance with the project specific guidelines provided by Radmat.
All installation to be according to guidelines and specifications supplied by Radmat.
