Flush Threshold Drain

IQ Glass offer a flush drainage channel suitable for use with all our flush threshold doors such as our large sliding glass doors, bi-folding doors and minimal pivot doors.

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.

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 


Design Integration

The design team at IQ have created a number of standard design details in order to integrate this flush threshold drainage channel with our flush threshold doors.

This hidden drainage channel is especially useful in conjunction with our slim framed sliding glass doors which have a sub floor level neoprene drainage base that can drain water below the finished floor levels.

Smaller ‘blade drains’ can be incorporated into some of our other flush threshold designs such as the Vitra Pivot.

Maximum Sizes

The Flush threshold drainage channel can be used as drainage across sliding door bases and be designed to continue along building facades or walls. Thanks to the specially designed Connector section with EPDM seal and screw these flush threshold drainage channels can be designed up to lengths to suit your elevation.

The pre made corner detail also makes easy work of these tricky corner sections with a pre cast metal top for a smooth design detail. At the end of the drain must be connected to outlet drainage via the pre designed spigots.

See it at the Showroom

The IQ Glass Showroom in Amersham has been designed to showcase the broadest range of architectural glazing possible, all in a real life environment.

A set of our aluminium bi folding doors are used as the main entrance doors to our office which include our flush threshold drain. Visitors walk over this flush threshold and our drain every day without even realising it.

Without a rebate, these bi folding doors require adequate water drainage to ensure that any rainwater is carried away from the threshold of the doors. Our flush threshold drainage detail is the perfect solution for this step-free entranceway.
