Usage

SikaRoof® Water-Infiltration Reduction Layer is suitable for use on inverted roofs finished with gravel ballast, green roof systems and concrete pavers on appropriate supports. It is intended to minimise the cooling effect associated with rainwater flowing down through the insulation and draining away. It can significantly reduce the insulation thicknesses required to achieve specified U–values.

Shelf Life

Will not expire under normal storage conditions.

Storage Conditions

The polyethylene packaging, which is recyclable, should not be considered adequate for outdoor protection. Ideally, rolls should be stored inside a building. If, however, outdoor storage cannot be avoided, then the rolls should be stored on their sides, on a clean dry surface, and covered with an opaque polythene sheet or weatherproof tarpaulin.
Technical Information
