Retention-Trim-for-side-image-page-11IKO Edge Retention Trims are L-shaped metal edging profiles that can be used on extensive green roofs which do not have a check kerb or parapet.

They retain the extensive landscaping system at roof edges and at intermediate positions on the roof, whilst allowing full drainage to the external rainwater systems.
