Modern Glass Technology by IQ Glass

Flush Threshold Drain for Doors

The IQ Flush Threshold Drain system provides a robust and effective water protection and drainage for flush threshold base frame details.

The hidden drainage channel can take up to 90 litres of water per minute and the exposed metal grille is anti-corrosive – suitable for marine environments or in conjunction with a chlorine or salt water pool.

The channel itself is an EPDM silicone sleeve which creates an effective thermally broken water barrier flush with floor tracks and the external floor finish. With a metal slim grate over the top.

IQ Glass Flush Threshold Hidden Drainage System

Drainage for Flush Thresholds

This versatile drainage solution can be engineered to suit all threshold thicknesses and is available in silver anodised aluminium (in stock) and titanium anodised aluminium (at an additional cost) . Pre made corner drainage channels allow tricky corner sections to be finished as neatly and minimally as the rest of the flush drain.

The square edged drainage has a slim and ergonomic design which makes it heel and small finger safe.

A flush drainage detail allows you to continue the frameless contemporary appearance across your internal floor finishes, across the base frame of your doors, across the drainage top to the external floor finish. This facilitates that internal to external blurring (the indoor outdoor effect) that is so popular within modern architecture, without having to compromise on performance
