ProTherm-40 is a trapezoidal foil faced insulated steel sheet for agricultural and low cost roof and wall applications.
The Foil faced insulated sheet is a through fixed roof and wall sheet, which can be used for all building applications, where the roof slope is 8° or more and vertical only on a wall. Buildings with no heat may need to be ventilated. |

Biological
ProTherm-40 foil faced insulated sheet is normally immune to attack from mould, fungi, mildew and vermin. No urea formaldehyde is used in the construction, and the sheets are not considered deleterious. |
QUALITY & DURABILITY
ProTherm-40 foil faced insulated sheets are manufactured from the highest quality materials, using state of the art production equipment to rigorous quality control standards, complying with ISO9001 standard, ensuring long term reliability and service life. The sheets have also been manufactured under Environmental Management System Certification ISO 14001:2004.
INSTALLATION INSTRUCTIONS
Side Lap
All external side laps to be weather sealed along the full length by an unbroken bead of 6mmx5mm thick butyl rubber sealant tape.
End Lap
When required all external end laps to be 100mm long, and weather sealed along the full width using two unbroken runs of 6mmx5mm thick butyl rubber sealant tape, first run located not more than 20mm upslope. End Laps to be tail stitched at each crown location 50mm upslope from end-lap. |
Fillers
Where flashings are fixed across the profile of the insulated panel, EPDM faced closed cell polyethylene foam fillers should be used to seal and close the profile. Seal the top, bottom and sides of each profiled filler with non-curing gun-grade sealant.
FASTENERS
Primary
All primary fasteners must be the high threaded type manufactured from carbon steel, anti-corrosion coated, and fitted with a 19mm diameter bonded stainless steel washer.
All fasteners to be located through every crown of the profile i.e. three fixings per panel per purlin.
Secondary
Side laps and flashings to be stitched at 450mm centres (maximum) with carbon steel stitching screws, complete with 14mm diameter bonded stainless steel washers. |
PURLINS
Typical purlin centres should not exceed 1500mm centres for general locations.
In some locations closer centres may be required
ProTherm-40 foil faced insulated sheets are suitable to be fixed to cold rolled, hot rolled and timber purlins. However when fixing to treated timber purlins an EPDM must be used to prevent any reaction between the treatment and the foil liner of the sheets.
ROOFLIGHTS
Rooflights can be used as part of the Protherm-40 sheet system and must be installed in strict accordance with manufacturer's instructions. |
