In many roofing systems, the sealing of the roof waterproofing membrane to the rainwater outlets relies on a clamping ring and a mastic seal.

 

This means there will be a future maintenance item directly in the water flow.To ensure that the connection between the Sarnafil roofing membrane and the rainwater outlet is as well sealed as the seams in the membrane itself, Sika Sarnafil provide a wide range of rainwater outlets that are simply hot air welded to the roofing membrane, creating a permanent watertight joint.

 

Each of the standard Sarnafil outlets has been tested against the requirements of BS EN 1253 (with the Sarnafil leafguard fitted) and eliminate the cold bridging associated with traditional metal rainwater outlets.

 

To complement the product range, Sika Sarnafil also provide a drainage calculation service, enabling the designer to optimise the number of outlets on the roof early in the design stage. As detailed information is required to enable us to carry out drainage calculations for a Sarnafil roof, please download and complete the Roof Drainage Evaluation - Data Request Form and return to and we will endeavour to complete these calculations within 3-5 working days.
