Roofgard SP1 High Performance Clamping Ring Rainwater Outlet

Roofgard SP1 Clamping Ring Outlet is intended for use with Icopal Monarplan PVC, Sureplan FPO, and Icopal Universal POCB waterproofing membranes in warm roof, cold roof and inverted roof applications.

The outlet is suitable for use with Icopal Single-ply roofing membranes in new build or retrofit projects. A refurbishment adapter ring can be used to allow the Ø 82 mm outlet spigot to slot into an existing Ø 110 mm outlet pipe. With its high hydraulic efficiency, the 82 mm outlet can achieve a greater flow rate than the originally installed roof outlet.

For installation procedures please download the Roofgard SP1 Rainwater Outlet Installation Guide.

Icopal’s marine grade cast aluminium Roofgard SP1 Clamping Ring Outlet has been designed specifically for use with Icopal single ply membranes. The outlet has a unique butyl strip which is recessed beneath the clamping ring to seal the membrane and prevent any possible water ingress into the building. With a high hydraulic efficiency, designers can reduce the number of outlets on a flat roof, reducing new build costs and risk.

It can equally be used in the retrofit market, as the 82 mm diameter outlet spigot can achieve a greater flow rate than the originally installed roof outlet.

In addition to its hydraulic efficiency, it can be supplied with a unique recessed insulation box that makes installation fast and trouble-free, whilst also making it compliant with Part L thermal bridging requirements.

The outlet grate and clamping ring are polyester powder coated in cyan blue, and the bowl body is mill finished. The leaf grate is available in a dome or flat grate.

The Icopal SP1 Clamping Ring Outlet assembly comprises the specified outlet with corresponding pipe, along with either the Dome or the Flat Grate.

Flow Rates

Flow rate data has been determined by physical measurements, based on a 35mm head of water adjacent to the outlet, all in accordance with EN 12056. The flow rates should be used as a guide only. Each drainage area will have individual features that may influence overall flow characteristics.

* Outlet limited by max capacity of Ø 82 mm pipe.

Note: 82 mm outlet connected to Ø110 mm pipework (refurbishment scenario) can achieve a flow rate of 10.3 L/s with Dome grate and 9.0 L/s with Flat grate.

Roofgard SP1 Clamping Ring Outlets are manufactured from marine grade aluminium and under normal UK atmospheric conditions, if correctly installed, have a life expectancy of 50 years or more. The life expectancy may be marginally reduced in environmentally aggressive areas, such as highly polluted or coastal locations.

Roof Outlets should be inspected at least once a year, particularly at the end of autumn to ensure the grates are not blocked, as part of a preventative maintenance programme.

Roofgard SP1 Terrace Grate Kit

The Terrace Grate can be used in applications with paving, terraces/balconies or green roofs. A Roofgard SP1 Terrace Grate is always used in conjunction with a Roofgard SP1 Extension Ring to raise the grate to the level of the paving. The Roofgard SP1 Extension Ring is 110mm high, and can be cut down to match the height of the paving, or be stacked one on top of another to raise the height of the square grate to match the overall system depth, for example in warm inverted roofs.

The kit comprises a terrace grate, an extension ring, and M6/M8 fixing nuts, bolts and washers. Additional extension rings can be ordered separately.
