Cold Melt®

Approved for use on

Balconies, Terraces & Walkways Blue Roofs Flat Roofs Green Roofs Inverted Roofs Podium Decks Roof Gardens Warm Ballasted Roofs Zero Falls Buried Roofs 

The BBA has judged Cold Melt® to be satisfactory for use as a protected waterproofing layer in inverted roofs, flat roofs, podium decks, balconies, warm roofs, green roofs and roof gardens, including zero fall roofs, with limited or pedestrian access.

Substrate

Concrete Insulation Boards Timber 

Cold Melt® is suitable for application on the following substrates:

• Precast concrete
• Concrete block
• Timber decks
• Rigid insulation boards

Durability

25 Years 

Cold Melt satisfies the requirements for a life of at least 25 years. In the opinion of the BBA, when fully protected and subjected to normal service conditions, the system will provide an effective barrier to the transmission of liquid water and water vapour for the design life of the roof in which it is incorporated.

In situations where maintenance or repair to the protection layer are necessary, the durability of the membrane may be reduced. In these circumstances, the Certificate holder should be consulted.

Installation Requirements

The system should only be installed by contractors who have been trained and approved by the Certificate holder.
