1. Plan for Insul-Baffle to be run parallel with, and for the full length of the building eaves. It is placed over the truss chords or rafters near the eaves. The edge of the Insul-Baffle should align with the top plate of the wall frames, or may over hang slightly.
2. Install Insul-Baffle placing a crenelation over the first truss chord or rafter in the run. Secure it with staples, flat head clouts or wafer head screws.
3. Unroll the roll fully, arrange and place Insul-Baffle crenelations over the roof framing to suit the framing centres. Ensure the Insul-Baffle edge is running parallel with the eaves and finishes at the outer edge of the top plate as a minimum.
4. Do not stretch the Insul-Baffle out – use light tension only to prevent sagging, but be sure to avoid deformation of the crenelations through stretching out excessively.
5. Fix using staples, flat head clouts or wafer heads screws.
6. If there is delay installing other roof elements, insulation, in windy conditions or where trusses or rafters are widely spaced, then additional restraint may be required. Masons Wrap Strap 19 or 25mm may optionally be installed over the Insul-Baffle and fastened to the roof framing.
7. Where Insul-Baffle rolls are joined, overlap by at least 1 full crenelation and make the join on framing.
8. When two parallel runs of Insul-Baffle are specified to create a 1200mm wide separation – install with crenelations aligned between rolls so air can flow unimpeded.
