APPLICATION  PROCEDURE

• Install building Blankets before roofing is fixed.
• Lay blankets with factory applied reflective aluminum foil vapour barrier over and at the right angles to purlins.  (Reflective surface of foil should face downwards).
• Allow sufficient slack for insulation when laying the reflective foil underneath the blanket to retain its normal thickness between purlin while still in contact with underside of decking.
• Where purlin centers are between 700 mm and 1200 mm, lay single sided lightweight reflective aluminum foil glass fibre single reinforcement, underneath the Blanket.
• Where purlin centers are greater than 1200 mm, use single sided foil cross reinforced glass fibres for better tensile strength.
• Lap at least 50 mm (2 in.) at joints and seal with 50 mm (2 in.) wide pressure sensitive aluminum foil tape .

• Install insulation blanket after roofing is fixed and hydro tested. 
• Lay blanket with factory applied reflective aluminum foil vapour barrier under at a right angles to purlins (reflective surface of foils should be face downwards).
• Allow sufficient slack for insulation when fastening under the purlins.
• Fasten insulation with either steel or aluminum flat bar (25 mm width).
• Bore hole every .60 m distance and attach with self - tapping screws.
• Lap 100 mm (4 in.) at joints and seal with 50 mm (2 in.) wide pressure sensitive vapor impervious aluminum foil tape.  

• Apply adhesive on the concrete slab and plate of mechanical pin (mech. pin spindle should be longer than insulation thickness).
• Adhere mechanical pin to the concrete slab at 60 mm (24 in.) distance on center in both ways.
• Impale the insulation blanket on mechanical pin and secure the insulation with pins, attach washers clips.
• If insulation blanket is faced with reflective aluminum vapour barrier, seal all joints with 75 mm (3 in.) wide aluminum pressure sensitive tape to prevent tranmission of water vapour.back to top
