The Allthrough is a drainage flange supplied with either a stainless-steel sleeve and clamp ring or one a piece solid ASA UV stabilised plastic unit. The Allthrough flange and sleeve connects to downpipe creating a visually continuous run of downpipe through balconies with integrated drainage. The clamp ring has an open and closed option for required functions.

The flange is to be rebated into the balcony substrate with membrane dressed into it, the Allthough sleeve and clamping ring is then installed directing the connecting downpipe directly into the drainage flange. When an open Allthough is used this will then allow drainage of the balcony through the downpipe and removes the requirements of further drainage fittings around the balcony.

The AT100 O has been hydraulically tested using an independent NATA accredited laboratory. It is suitable for draining the roof and individual balconies up to 5 litres per second without splash from the downpipe through the Allthrough grating onto waterproof membrane level.

For all other product selections roof drainage will require a closed sleeve.

Please note the compatibility with waterproof membranes when selecting a flange option, especially if a heat-applied membrane is being used.

Accepted Alternative Solution to meet standards required to protect penetrations in membrane deck while also allowing downpipes to pass through.
