  • At eaves, use an eaves guard or eaves sheet extending into the gutter then overlap the eaves guard with the first run of TLX Batsafe™, black side uppermost (1) Lay TLX Batsafe™ parallel to eaves, starting at the eaves and working up the slope of the roof (2).
  • For unsupported applications, allow TLX Batsafe™ to drape slightly (at least 10mm) between the rafters to allow water run-off.
TLX Batsafe installation step 3
  • Where TLX Batsafe™ is installed over a fully supported system, fix counter battens, at least 25mm thick, over the underlay and through to the rafters using corrosion-resistant clout nails. Fix tile battens to the counter battens so that there is an uninterrupted air space between the underlay and the roof tiles or slates.
  • Lap TLX Batsafe™ in according to the tables minimum overlap requirements.
  • At valleys Batsafe or a traditional bitumen 1F felt that does not contain non-woven material such as spunbond should be used underneath the valley lining itself, with the lapping over it under the first tile/slate.
