InvisiWeep Blue / Black - Boxed 50's

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 patent-pending 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.

• 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.
