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.
