BOSS PenoPatch is a low cost, simple method of sealing blank openings, individual cables, small bundles of cables, pipes and conduits in a range of one hour fire walls.

Made with a fire-resistant advanced formula putty with a strong bonding capability, the BOSS PenoPatch simply presses onto the wall around the service and instantly provides up to a 60 minute fire rating.

The BOSS PenoPatch has been tested to various international standards including AS1530.4-2014 and BS EN1366-3: 2009. It has been tested on some of the most onerous conditions including single layer plasterboard systems.

Under fire conditions the product maintains its bond to the substrate. The integrity and insulation is then maintained by the stability of the remaining product char.

BOSS PenoPatch is supplied in the form of 60mm diameter discs in packs of 20 units (100mm available on request).

It is ideal for electricians, plumbers, gasfitters, HVAC installers, maintenance personnel and passive fire applicators — simply remove the backing paper, put the slot over the cables or pipe, and stick to the wall moulding the disc around the service.
