High Bond Polymer Primer

DESCRIPTION
High Bond Polymer Primer is a quick drying green synthetic rubber based primer for use with hot melt waterproofing systems designed to penetrate and seal a variety of porous surfaces including masonry, concrete, cementitious screed/renders, existing waterproofing and structural steelwork. High Bond Polymer Primer creates a base seal and improves the adhesion of hot melt waterproofing solutions.

APPLICATION
• The substrate must be clean and dry, structurally sound and free from laitance, oils, dirt, moss, lichen and loose materials.

• Apply by brush or roller ensuring the primer is well applied into the surface. Apply a thin coat and avoid pooling. Allow to dry thoroughly before over coating. Ensure ventilation is sufficient.

• High Bond Polymer Primer requires between 15-30 minutes to dry, with a working time of 4 hours.

• High Bond Polymer Primer must be completely dry before applying hot melt membrane.

ProTherm RockFace A2 SL Soffit Board

DESCRIPTION

ProTherm RockFace A2 SL is a non-combustible, fire tested Soffit Insulation Board designed to insulate semi exposed concrete soffits. Manufactured with non-combustible Stonewool factory laminated to a 6mm thick weather resistant high impact calcium silicate fibre cement facing board, ProTherm RockFace A2 will not develop smoke or promote flame spread, even when directly exposed to fire. It also repels and drains away water completely drying out while maintaining its original physical properties. The calcium silicate fibre cement facing board is BBA certificated (BBA certificate No. 21/5983) and independently tested and classified as Category A for external use in accordance with EN 12467:2012. Available in a range of thicknesses, see declared performance table for available thickness.

Available in a range of thicknesses, see declared performance table for available thickness. RockFace A2 SL has a Zero Ozone Depletion Potential (ODP), a Global Warming Potential (GWP). Certificates ISO 9001@2008 Quality Management System,
ISO 14001 :2004 Environmental Management System, EPD as per ISO 14025 and EN 15804. 

For a comprehensive NBS J31 specification contact Radmat Building Products.

SUITABLE USE

RockFace A2 SL can be mechanically fastened to:

• The underside of a profiled steel, flat steel or concrete soffit on buildings over 18m providing the structure meets the performance requirements of BS9991:2015, Approved Documents B and BS 8759:2020.

INSTALLATION

RockFace A2 SL boards should be fixed using Ejot DDS fixings with the Ejot DDT70 washer or similar, direct to the concrete soffit, refer to the diagram below for the recommend number and positioning for each board size. Fasteners and washers should be installed so as to prevent RockFace A2 SL panels becoming dislodged by wind or maintenance work.

When fixing directly to a steel or concrete soffit RockFace A2 SL boards fasteners should be positioned a minimum of 100mm in from the edges of the board, at 300mm centres across the width and at 500mm centres along the length (achieving 7 fasteners per board).  The minimum penetration of the fasteners into the substrate must comply with the fastener manufacturer recommendations. A space of 0.5 to 2mm should be left between each board to allow for thermal expansion.

At perimeters the RockFace A2 SL must either abut a vertical surface (a space of 0.5 to 2mm should be left between each board to allow for thermal expansion) or be closed off with a suitable cover flashing.

Suitable for use with any inverted roof waterproofing membrane including hot melt, liquid applied or reinforced bitumen membrane. Consisting of cellular glass with a pre-applied inorganic coating# on the topside both the core material FOAMGLAS® INVATHERMTM is manufactured from specially graded recycled glass (≥ 60%) and natural raw materials which are available in abundant supply (sand, dolomite, lime). Totally inorganic FOAMGLAS® INVATHERMTM contains no ozone depleting propellants, flame resistant additives or binders, VOC or other volatile substances.

*Class A1 to BS EN 13501-1, sometimes referred to as ‘non-combustible’
#As product is made from natural materials the colour cannot be guaranteed and can vary in batches.

SUITABLE APPLICATIONS
FOAMGLAS® INVATHERMTM is suitable for use in all forms of inverted roof applications including on Specified Attachments. Suitable applications include projecting open balconies, projecting enclosed balconies, recessed open balconies, recessed enclosed balconies, roofs, roof terraces, enclosed balconies over heated space and insulated walkways.

NHBC Requirements 

For Inverted Warm Roof systems, the FOAMGLAS® INVATHERMTM system is acceptable providing the below criteria are achieved: 

• FOAMGLAS® INVATHERMTM is installed over the waterproofing layer with tight butted joints 

• FOAMGLAS® INVATHERMTM is covered by a Water Flow Reducing Layer (WFRL) 

• The pedestals must be certified for reaction to fire performance as either Euroclass ‘A1’ or A2’ in conformance with EN 13501 

• The pedestal products must have a circular base with a diameter of at least 170mm and be supported by a rubber underlayment as prescribed in the FOAMGLAS Technical Data Sheet, such as Buzon A-PED-107-142 Adjustable Pedestal installed on Buzon U-pad 200 x 200 x 6mm. 

• The maximum load indicated in the Product Data sheets is not exceeded. 

CERTIFICATES
ISO 9001:2008 Quality Management System, ISO 14001:2004 Environmental Management System, ISO 14025/EN 15804 Environmental Product Declaration, BS EN 13501-1 Reaction to Fire Classification.

FIRE PERFORMANCE
As a roofing system for roofs, roof terraces, enclosed balconies over heated space and insulated walkways
In accordance with Annex of Commission Decision 2000/553/EC, when used in an inverted roof specification including an inorganic covering of either loose laid gravel with a thickness of at least 50mm or a mass ≥ 80 kg/m², sand/cement screed to a thickness of at least 30mm, or cast stone or mineral slabs of at least 40mm thickness a roof system incorporating FOAMGLAS® INVATHERMTM can be considered to be unrestricted under the national Requirements (Classification Broof(t4) to BS EN 13501-5:2016).

As a roofing system component for Specified Attachments such as projecting open balconies, projecting enclosed balconies, recessed open balconies and recessed enclosed balconies
