25mm Xtratherm FR/ALU Flat Roof PIR Insulation Board Thin-R is a top-class polyisocyanurate foam core insulation board with vapour resistant gas-tight foil facers suitable for loose laid ballasted and mechanically fixed single ply waterproofing systems.

Thin-R FR/ALU is a thermally efficient roofing board with a certified thermal conductivity (λ - lambda value) of 0.022W/mK.

Xtratherm PIR insulation boards are stable, rot proof and will remain effective for the life span of the building (depending on specification and installation).

Thin-R provides the most efficient U-values with minimal intrusion into valuable living space.

FR/ALU can reduce heat loss and save money on energy bills (provides excellent thermal bridging details).

Care should be taken to avoid contact with acids, petrol, alkalis and mineral oil, when contact is made, clean materials in a safe manner before installation.

Thin-R insulation foam core and composite gas-tight foil facings resist attack by mould, fungi, bacteria and microbial growth.

Xtratherm FR/ALU foil faced insulation boards are suitable for use on roof decks that are subject to maintenance traffic.

Walkways should be provided on roofs requiring regular pedestrian access. 

When the roof is complete, protective boarding should be laid if additional site work is to be carried out. 

The completed roof should not be used for storage of heavy materials or an air conditioning plant.

Application:

 · Xtratherm FR/ALU insulation boards should be laid over the vapour control layer in a break bonded pattern. 

 · The long edges of the boards should be laid at right angles to the corrugations and all board joints must be fully supported by the deck. 

 · The FR/ALU insulation boards are secured by approved mechanical fixings.

 · The requirement for a separate water vapour control layer should be assessed in accordance with BS 6229. 

 · Typically a 1000 gauge polythene should be used with all joints lapped and sealed. 

 · Any fixings that penetrate it must be of the self sealing type that fuses to the vapour control layer during application.

 · FR/ALU is not suitable for applications with built-up bitumen based roofing or mastic asphalt systems.

Certification and standards:

 · BBA Certification No. 11/4817. 

 · BS EN ISO 9001 Quality Management System.

 · BS EN ISO 14001 Environmental Management System.
