ProTherm SD Upstand Board

DESCRIPTION
ProTherm SD Upstand Insulation Board is used to thermally insulate and protect upstand walls in inverted flat roof systems. Manufactured from a CO2 blown extruded polystyrene foam factory laminated to a 6mm thick weather resistant high impact facing board. Available in a range of thicknesses, see declared performance table for available thickness. 

The ProTherm XPS Insulation backing board has a Zero Ozone Depletion Potential (ODP), a Global Warming Potential (GWP) of less than 5, achieves a Green Guide to Specification A rating and an Ecopoint rating of 0.0482. For use with Inverted roofing waterproofing such as PermaQuik PQ6100, EshaFlex, EshaUniversal, ParaFlex and ReadySeal. 

ProTherm SD Upstand Insulation Board is not intended to provide a final architectural/aesthetic finish as the cementitious facing may vary in colour from batch to batch. To achieve a consistent aesthetic finish the Cement Particle Board (CP Board) facing can be primed and decorated with an appropriate masonry paint or render finish.

Suitable Applications
ProTherm SD Upstand Insulation Board is suitable for use as an upstand board in all applications on all buildings as defined by Approved Document B volumes 1 and 2, except on Relevant Building and Specified Attachments. 

Relevant Buildings & Specified Attachments
ProTherm SD Upstand Insulation Board is suitable for use as an upstand board on roofs, roof terraces, enclosed balconies over heated space and insulated walkways in an inverted roof construction when it is installed: 

1. At a maximum height of 150mm above the roof finish/walking surface. 

2. At a thickness no greater than 60mm (insulation element only). 

3. To not cross a compartment wall line. 

4. Not against habitable space. 

If any of these installation requirements cannot be met ProTherm RockFace A2 must be used. 

ProTherm SD Upstand Insulation Board is not suitable for use in inverted roof applications on Specified Attachments such as projecting open balconies, projecting enclosed balconies, recessed open balconies or recessed enclosed balconies. 

ProTherm SD Upstand Insulation Board is not suitable for use in warm roof applications (where the waterproofing is installed above the insulation board). 

APPLICATION
Install ProTherm SD Upstand Insulation Board after completion of the PermaQuik PQ6100, EshaFlex, EshaUniversal, ParaFlex or ReadySeal inverted roofing system.

ProTherm SD Upstand Insulation Board is bonded to the waterproofing using an Insta Stik bead it is also trapped at the base by the horizontal ProTherm insulation board. As long as the ProTherm SD Upstand Insulation Board are well protected no additional attachment method is required unless the ProTherm SD Upstand Insulation Board is more than 3 times the height of the horizontal ProTherm insulation board. 

Where the ProTherm SD Upstand Insulation Board is more than 3 times the height of the horizontal ProTherm insulation board, and less than 750mm in height, the ProTherm SD Upstand Insulation Board must be trapped at the base by the horizontal ProTherm insulation board and have continuous retention across the top face of the board. 

Where the ProTherm SD Upstand Insulation Board exceeds 750mm above the roof finishes and is trapped at the base by the horizontal ProTherm insulation board the ProTherm SD Upstand Insulation Board must be either: 

  • Bonded with Insta Stik Roofing Adhesive applied in 19-25 mm beads at 300mm centres for the full height of the ProTherm SD Upstand Insulation Board AND have a single DDS fixings (or equal approved) installed through the centre of the ProTherm SD Upstand Insulation Board a minimum of 75mm from the top of the ProTherm SD Upstand Insulation Board.
  • Mechanically fixed directly to the upstand wall at 600mm centres using Speedline DDS fixings (or equal approved).
     
  • Where it is necessary to cut ProTherm SD Upstand Insulation Board to size use a TCT saw (suitable PPE must be used including a face mask to guard against dust).
