How to Install TLX Batsafe™
Applications
- Can be used in warm or cold roof constructions.
- Suitable for unsupported and supported applications.
- May be laid directly over insulation and insulated sarking board in convection-tight roof designs.
Fixing Instructions
Install TLX Batsafe™ in accordance with the following instructions and with the relevant standards, for example:
- BS 5534: 2003 Code of Practice for slating and Tiling, Part 1.
- Design: BS 5250 : 2011 Code of Practice for the control of condensation in Buildings.
- 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.
- 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.
