- Compressive Strength: >150kPa @ 10% Compression
- Thermal Conductivity: 0.022 W/mK
Unilin (previously Xtratherm) FR/ALU is faced with gas-tight foil. Xtratherm FR/ALU foil faced roof boards are suitable for use below single ply mechanically fixed roof membranes.
Note: FR/ALU is not suitable for applications with built-up bitumen based roofing or mastic asphalt systems.
Unilin (previously 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.
Unilin (previously Xtratherm) FR/ALU foil faced insulation boards are suitable for use on roof decks that are subject to maintenance traffic. Walk ways 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 air conditioning plant.
Roof design:
Consideration should be given to the recommendations of BS 4841: Part 3 and those of the Single Ply Roofing Association.
Falls:
The fall on a flat roof should be constant and steep enough to ensure that rainfall does not pond.
Fire performance:
The fire rating when tested to EN 13501-5 and BS 476 Part 3 ‘External Fire Exposure Roof Test’ will be dependent upon waterproofing system specified
U Value information:
Unilin (previously Xtratherm) FR/ALU foil faced roof boards are suitable for use below single ply mechanically fixed roof membranes.
Note: FR/ALU is not suitable for applications with built-up bitumen based roofing or mastic asphalt systems.
Vapour Control Layer
The water vapour control layer should be laid with 150mm laps, which are turned up at any vertical upstand. When the insulation boards have been positioned the laps are turned over and sealed, prior to the roof finish being completed.
Laying (Metal/Timber Deck)
Unilin (previously Xtratherm) FR/ALU foil faced 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 generally secured by approved mechanical fixings.
Laying (Concrete Deck)
Unilin (previously Xtratherm) FR/ALU boards are laid over the vapour control layer in a break bonded pattern and secured with approved mechanical fixings, or secured under a ballasted system. Care should be taken to ensure that the concrete deck is graded to the correct falls, dry, clean and free from any
projections or gaps.
Fixing
The specification for fixing Unilin (previously Xtratherm) roof boards will vary with the location, roof height/area and topographical data. Architectural specification should be consulted. Generally with 2400mm x 1200mm boards, a minimum of 6 fixings are adequate, located between 50mm and 150mm from all edges, additional fixings may be placed along the centre line. Additional fixings around roof perimeter may be required. 11 fixings per 2400mm x 1200mm sheet is recommended. Counter sunk washers, 50mm in diameter should be used with each fixing.
However, BS 6399:Part 2 should always be consulted. During the construction process, the construction should be protected from rain penetration during breaks in the process.
What makes this different to Unilin (previously Xtratherm) Floor Insulation boards?
- Manufactured with slightly higher compressive strength – i.e it can withstand more loading
- Manufactured to tighter tolerances – for fixing the water proofing and/or air tight membranes etc
- There are less steps built into the surface of the insulation
