Invisiweep - Buff

The almost-invisible, multi-function wall weep for discharging water from external walls. Suited for use with the Timloc cavity tray system, over external lintels and on external masonry walls. Invisiweep has numerous innovative features, including a venturi effect outlet tube that reduces water pressure, allowing for optimal drainage.

Invisiweep satisfies all NHBC requirements and meets British standards: BS5250, BS5628 and BS8215.

Product Information:

- Integral 4mm vermin barrier and rainwater baffle as recommended by BS5250, to reduce ingress of large nest building insects, mammals, and rainwater penetration to the cavity.

- External ribs & tapered profile, to key into mortar for secured fixing.

- Full height upstand to cavity side, to maintain drainage and minimise the impact on blockage from cavity cement build up.

- Discrete water outlet, to minimise the impact and reduce visibility for a truly concealed wall weep.

- Venturi effect outlet tube to reduce pressure, allowing for optimal water drainage.
