Timloc 5" Aero Core with Cowl & Baffle Terracotta 
Crafted from injection moulded recycled polypropylene, the Timloc Underlay Felt Lap Vent is naturally lightweight and resistant to decay, offering a long-lasting product that won't deteriorate over time. It is solely designed only to enhance existing ventilation via felt/membrane lap joints.
This product has been taken through various regulations and standard bodies to verify it, these include;
- Manufactured to British Standard BS EN 9001 and BS EN 14001
It can pass BS5534:2014 and BS5250 as well; however, these are only achieved if they are installed correctly. Otherwise, it will not accomplish these regulations and, therefore, not work as effectively. Please read the technical data sheet for installation advice to understand how to fully install these to satisfy both regulations.
